THE MUSHROOM r> U U K. ^ POPULAR GUIDE TO THE IDENTIFICATION AND STUDY OF OUR COMMONER FUNGI, WITH SPECIAL EMPHASIS ON THE EDIBLE VARIETIES BY NINA L. MARSHALL WITH MANY ILLUSTRATIONS IN COLOR AND BLACK AND WHITE PHOTOGRAPHED FROM NATURE BY J. A. & H. C. ANDERSON NEW YORK DOUBLEDAY, PAGE & COMPANY 1905 Copyright, 1901, 1904, by Doubleday, Page & Company Korfajooli ^resB : Berwick St Smith Co., Norwood, Mass., U-S-A. PREFACE The author of this book makes no claim to the discovery of the facts presented. The ma- terial has all been drawn from monographs written by men who have made specialties of the different divisions of fungi. A list of works consulted is given at the close of this book. The plates are reproductions of photographs made by Mr. J. A. Anderson, and coloured by Miss H. C. Anderson. They are as true to nature as it is possible to make them with the best meth- ods of reproduction now known, and by them alone an acquaint- ance with many species may be acquired. Many of the cuts have been redrawn by the author from vari- ous reliable sources, and many have been drawn directly from nature. With a few exceptions, the line drawings of sections were made from the specimens photographed. It has been the aim of the author to write a book simple enough to serve as a source of knowledge for the many who, though busy with other pursuits, yet take an in- terest in science and wish to obtain information about the fungi, either for the sake of using them as food, or for the Coprinus coniatus.

A great effort has been made not to sacrifice accuracy in this attempt. The number of species of the fungi is so great that to de- scribe them all would necessitate a book of huge dimensions, so that it has seemed best simply to give a general idea of the characteristics upon which the larger groups, the classes, orders, and genera, are based, by describing some of the species in each. Seven genera of the Spore-sac Fungi are illustrated with ten species, and thirty-five genera of the Basidiomycetes with seventy-three species, making a total of eighty-three species represented by photographs in colour and half-tone. In addition a number of species are given in rough pen drawings, with sufficient accuracy for identification, and many species have been described without illustration. An effort has been made to describe the species in terms intelligible to the average reader without constant reference to an unabridged dictionary, and, whenever possible, the terms have been illustrated by line cuts. Although the technical names necessarily used are a serious hindrance to the popularization of the study of fungi, it has seemed best, in most cases, to give only the Latin form of the names of species, since, by so doing, there will be less danger of confusing harmless species with those which are harmful ; and, also, if their Latin names are adhered to, one will find it much simpler to consult the scattered literature on this subject, as this nomenclature is used by all naturalists of whatever nationality. That the pronunciation of names may be rendered as simple as possible, each vowel has been marked long or short. These vowel-marks are not necessarily indicative of the true syllabic quantity, but are rather diacritical points denoting the popular pronunciation by the English system. Each word has been divided into syllables according to the accepted rules, and an accent has been placed on the syllables to be accented. The author is under deep obligations to Professor Lucien M. Underwood, of Columbia University, for aid and encouragement in the work of this book, and for his cheerful willingness at all times to assist in the search for material and in the work of revising proof. VI Preface Thanks are also due to Professor Charles H. Peck, the New York State Botanist, for his kind assistance in identifying many of the specimens illustrated. A list of books consulted has been placed at the end of the book, for the benefit of those who may wish to pursue the study further. Coprinus comatus.

The gills of the Agaricus are not fastened to the stem, but are rounded off at the end near the stem, while others, between the long ones, extend from the edge of the cap only far enough toward the stem to fill up the angles formed by the long gills. The surface of the gills is the fruiting portion of the mushroom. It is here that the spores are formed. The structure of the fungus plant up to this point has been similar throughout. A loose tangle of threads underground formed the myce- lium—the food provider. A more closely matted tangle above ground formed the stem and cap and veil, and even the central part of the gill — the fruiting parts of the plant. On the surface of the gill a difference in structure is found, which will be clearly understood from a picture of a thin section cut across a gill. (i) The central portion of the gill is made by loosely tangled mycelium threads {tr) draping themselves in thin plates from the surface of the cap. (2) Just outside of this loose mycelium, on either side, are layers of short cells {c), which bear club- shaped bodies standing out over both surfaces of the gills {b). (3) Each club bears two slen- der processes {st) at the free end, and each process bears a spore {sp). 13 Com smut Leaf rust on Hepaiica triloba From Spore to Mushroom AH corn smuts, wheat smuts, leaf rusts, toadstools, puff- balls, and brackets bear their spores on club-like cells, and for this reason are put in one group, called Basidiomycetes. The fact that corn smuts and leaf rusts feed on living plants, while toad- stools, brackets, and pufifballs feed on dead plants, separates them in- to two groups ; the smuts and rustsformingthe lower group, and the others the higher group. It is the higher Basidiomycetes which we wish to con- sider, as this group includes most of the con- spicuous fungi, most of the edi- Pouch-fungus section, to show spores in hollow rind Section to show gills Section of a Boletus, to show pores Clavaria with spores on spines ble, and those fungi which are dangerous because of their re- semblance to edible species. Remembering that toadstools, puffballs, and brackets all start from spores ; that all have the tangled thread - like plants, seeking the dark ; that they all have the spore recep- tacle in the light, and bear their spores on club-like cells, one can readily understand their be- ing put in one group. With a few exceptions not necessary for us to consider, all the higher fungi naturally divide into two groups — pouch-fungi (Gasteromycetes), which conceal their spores in a definite rind, or peridium, as the puffballs do ; and membrane fungi (Hymenomycetes), now called Agari- cales, which bear their spores exposed on the surface of gills, pores, spines, or teeth, as the garden mushrooms, the Boleti, the Clavarias, and the Hydnums. Section of Hydnum, to show teeth H CHAPTER IV: THE KEY WHAT A KEY IS, AND WHY A NAME IS DESIRABLE A KEY in the study of botany is a guide by which a student may trace a specimen until he finds a name for it. Having found a name, he may learn from books or from friends what is known of its habits of growth, of its value as a food or drug, whether it is harmful or harmless, whether it is to be protected or whether war is to be waged against it. He may learn whether it has figured in history or the myths, and how the poets and artists viewed it, and may perhaps learn to see it with their eyes. He may watch similar specimens as they grow, and may add the results of his observations to the facts already recorded about his specimen. HOW A KEY FOR FUNGI IS MADE, AND WHY IT IS DESIRABLE In the first place, only such plants are considered as grow from spores and have no leaf-green. (The spore characteristic is one the amateur must decide upon either by seeing the spores or by inferring their existence from the fact that seeds do not appear.) There are some thirty-five thousand species of fungi known to botanists, so that it would be impossible to find a name for a specimen if one had to read at random until the right description for his specimen was found ; but since all of these plants may be put in one or another of three groups, on account of certain points of resemblance which they have in common, and since these three groups may each in turn be divided and subdivided, one may, by selecting groups rather than individual specimens, find a short path to the name desired. The three primary groups, called classes, are made as follows : The first contains many mould-like fungi which resemble one another in microscopic characters. The second contains other mould-like fungi and many con- The Key spicuous fungi which bear their spores in transparent sacs (see first page of Key). The third contains all fungi which bear their spores on en- larged cells called basidia (see first page of Key). To even partially understand the inconspicuous fungi is a task impossible to one who is not familiar with the use of a com- pound microscope. To acquire a knowledge sufficiently accu- rate to identify nearly all of the conspicuous fungi is within the power of any intelligent person, for the two groups or classes containing the conspicuous species may be divided, on account of easily distinguished characters, into groups called orders. The orders may be divided into groups called families, and the families into groups called genera (singular genus), and the genera into individual specimens called species; and all these groups may be arranged in such a way that the series of selec- tions may be quickly made. Such an arrangement of groups is called a key. i6 Key . «0 w >«i qi c^ -«'Y c/l JJ Q .^ O^ I/) < O N ,S ra U 0) ut d, >i^ ;?H Qh C-- C jn o o ;_ J5 O ^ ^ ..-* o c re 3 [1. on o I| 00 ^ rt p ■ S o o CO < ^ vO US •n u u o hn u- m >1 a. ■^ \ * US ^ s bjO — M fi _ Ul •— ' fTl y-^siii , 1 ^ (J T) f § J3 c 1 ^ 0) c >1 3 o c« -a •a o XI o u o t) p 3 T-t fl) c/l 3 1) C CU ■4-» < ■C3 E ( Cu ';2 'rt^ rt 3 « h c r- n OJ u cx >^ •r) x: <1J Vi -*-• lU >-. u.

Their family name, Agaricacece, is derived from a typical member of the family, Agaricus campestris. The family is the largest and most widely distributed of all the families, and contains some five thousand described species, which are placed in groups or genera, more or less large, based on such characters as the colour of the spores; the position and shape of the lamellae; the colour and texture, as well as the shape, odour, taste, and appendages of the cap and stem. The colour of the spores is one of the most important char- acteristics, as the decision as to whether the plant is wholesome or not often rests upon it. The colour may be determined by placing the cap, with spore surface down, on a sheet of white or black paper, and leaving it for a time under an inverted glass, so as to cut off all drafts which may blow the spores away. A print of the radiating gills will then be made in the colour of the spores — white, pink, rusty brown, or black. For external characters of the stem, one must be careful to get the entire stem from the ground ; for a most important char- acteristic, the volva, if present, will be found at the base. The volva may be membranous and attached to the base, excepting at the rim, or membranous and loose, or present only in the form of rings of scales at the base, with perhaps traces on the surface of the cap. The surface of the stem may be smooth or rusty or mealy white. It may or may not have near the cap a ring of the membrane which covered the gills of the young plant. The character of the lamellae and the internal characters of the stem may best be determined by cutting the cap and stem from top to base with a sharp knife, for then it may be seen whether the gills are free from the stem or attached to it, or 46 White-spored Series Veil whether they grow down on the stem; and whether the stem is hollow, solid, or filled with web-like mycelium, and whether it is fleshy or has a tough and hard rind. The lamellae may be of different or of equal lengths, and their edges may be entire or toothed or thin or blunt. To know a genus of the gill-bearing fungi, one must know the cap, gills, stem, and habit of growth which characterise that genus. A very young plant of the genus Amanita is enveloped in a membranous wrapper. The relation of the young plant to the wrapper will readily be understood by cutting a young plant through its length. As the plant grows, the wrapper is ruptured, a part is left at the base to form a cup or sheath, or a part maybe carried up on the cap, to ap- pear in small patches. The cap is, as a rule, regular and broadly convex. It may be almost flat when mature. The stem has a conspicuous collar and the gills are free from the stem. There are twenty American species in the genus Amanita ; some of them are the most poisonous Patches., fungi known, while others are most highly esteemed for the table. Since the most dan- .Cap gerous species belong to this genus, it would be better for the )...Voiva amateur not to eat of specimens Wrapper. Section of young plant in wrapper Young plant in wrapper Free gills .Stem Wrapper ruptured A. muscaria (See Plate III.) which havestalks with a swollen base surrounded by a cup- like or scaly envelope, especially if the gills are white. In gath- ering all white-gilled species, care should be taken to get A-mSn'-l-tS 47 Fun£ri with Gills below the base of the stalk ; for it often happens that the bulb is broken off and left behind, and thus the principal charac- teristic lost which would mark it as a specimen not to be eaten. Death Cup; Poison Amanita (Poisonous) Amanita phalloides Cap or Pileus — White or greenish or greyish brown; smooth, no striations ; width, 3-5 inches. Stem or Stipe — Ring present. Abruptly bulbous at the base ; bulb margined by the wrapper remains. White in white- cap forms, tinged with a paler shade than the cap in brown- cap forms. Pithy when young, hollow when old. 3-6 inches long. F«7— White in white-cap forms, tinged with brown in brown- cap forms. Gills or Lamellce — White, free from the stem, rounded at the stem end, rather broad. Spores — Globose and white. /%j/4— White. Time — July to October. Habitat — Woods, groves, open places, and pastures. The poisonous principle of the death cup is known as phal- lin, one of the tox-albumins, the poisons found in rattlesnakes and other venomous animals, and the poisons which produce death in cholera and diphtheria. The phallin acts directly upon the blood corpuscles, dissolv- ing these, so that the serum of the blood escapes from the blood- vessels into the alimentary canal and drains the whole system of its vitality. There is no known antidote by which the effects of phallin may be counteracted. If one has eaten of the Amanita phalloides, the only chance of saving life is to remove the undi- gested parts from the alimentary canal by stomach-pump and oil purgatives ; then, if the amount of phallin absorbed into the system is not too great, the remainder may wear itself out on the blood and the patient may recover. The amount of the fungus which is necessary to produce death is small; even the handling of specimens and the breathing in of spores affect some people unpleasantly. Phai-loi'-des 48 DEATH CUP. DESTROYING ANGEL {Amanita j^kalloides^ Fries) Reduced. Nat. size; Cap, 35^ inches; stem, /J^ inches White-spored Series Fly Amanita (Poisonous) Amanita muscaria Cap or Pikus — Orange red to pale yellow or almost white. The young plants are brighter, and fade from the margin inward as the plant matures. Floccose scales, the wrapper remains,- are scattered on the cap. The margin is often striate. 3-6 inches broad. Stem or Stipe — White or slightly tinged with yellow. Pithy or hollow. Base not broad and abrupt, but ovate, covered with the scaly margins of the wrapper. 4-6 inches long. Veil and Ring or Annulus — The veil covers the gills of the young plant, and later is seen as a collar-like ring on the stem. Gills or Lamella — White or slightly tinged with yellow. Various in length ; short ones terminating in length with almost vertical abruptness. Spores — White, broadly elliptical. Flesh — White, tinged with yellow under the epidermis. Habitat^ Wong roadsides, on borders of fields, in groves of conif- erous trees. It prefers poor soil, gravelly or scanty. It grows singly, not in groups. Time — June until freezing weather. Young Plant — This is at first egg-like, then dumb-bell shaped. As the parts within expand, the wrapper breaks up into scales, so that the convex, unexpanded cap is densely covered with more or less concentric fragments of the wrapper, and the bulbous stem is covered with rings of iringy scales. As the stem expands, these scales are left on the bulbous base, while the fragments on the cap are more widely separated by the growth of the cap. The fly amanita is a very conspicuous and handsome species. There are conflicting statements concerning the properties of this fungus; some claim that it is edible, and yet it is known to have caused much sickness and many deaths. It caused the death of the Czar Alexis of Russia, and of the Count de Vecchi in Washington. It is said that it is cooked and eaten by the Russians, and still it is on record that several French soldiers ate of it in Russia and became very ill. The Siberians steep dried specimens of the fly amanita in whortleberry juice, and thus make a drink which produces an intoxication similar to that produced by the "haschisch" and "majoon" of the East. Miis-ca'-rl-S. 3 49 Fungi with Gills There is something about it particularly attractive to flies, and yet for them to sip its juices means death, as may be seen by the circle of dead flies lying on the ground under the shadow of its cap. The chief poison of this fungus is an alkaloid called musca- rine, which paralyzes the nerves controlling the action of the heart. Injections of atropine in doses of from one one-hundredth to one-fiftieth of a grain are employed as an antidote for this poison. In addition, the most powerful emetics are used. Cap striate, and free from warts Orange Amanita (Edible) Amanita Ccesared Cap or Pileus — Smooth, glabrous, and free from warts or scales. Red or orange, fading to yellow on the margin or all over the cap. Margin distinctly striate. When fully ex- panded, nearly flat. When moist, slightly sticky and viscid. Stem — Yellow. When young, fibrous or cottony within, later hol- low. Wrapper or Volva — White and mem- branous, loosely sheathing the base of the stem. F^y— Covers the gills of the young plant. Remains are seen on the stem only, where it hangs down like a white ruffle. Gills or Lamella — Rounded at the stem end and not attached to the stem. Yellow, an exception to the rule that the col- our of the gills in mature plants resembles the colour of the spores. Young Plant — When young, the cap and stem are contained in a wrap- per not unlike a hen's egg in shape, size, and colour. As the cap and stem within develop, the wrapper ruptures in its upper part, the stem elongates, and the cap is carried up, CS'-sS-re'-i 50 Section of A.

Spores — White, elliptical. Flesh — White stained with yellow under the separable epidermis and next the line of attachment of the gills. Taste — Mild and pleasant. Habitat — Thin woods, preferably pine woods and sandy soil. Abundant in southern Europe, common in the Southern States, and occasionally found in New York and Massa- chusetts. Time — July, August, September. The Amanita CcRsarea is one of the handsomest species. The Greeks and Romans esteemed it as an article of food. The names, "Food of the gods," "Cibus Deorum," " Imperial mush- room," "Caesar's mushroom," and " Kaiserling," suggest the esteem in which it was held. 51 Fungi with Gills i ^.g^ (H er. stem n rgined tipper. i o c c n -^ V- tS sT o (li ilar t( h sma Base ightly m of the w i o E 'o "-§ § 3 >^ E ■«-( P E < 'TB o C t/5 Pileus ia, bu -Noc ly; on rema > .bp C/3 re 00 >e« >- 8S ca -Q >^ 3 c " a. . s +-" s. tu la £ < « "5= « « "S c 2 X H O r Pileus — Or orned with nsisting of ptured volv —No cup. sm bulbous 6 -White, ra w tinted. ent, the pla Fr6s «.

See Genus, p. 53 White-spored Series GENUS CANTHARELLUS The members of the genus Cantharellus differ from all other gill-bearing fungi in that the gills are in the form of shallow folds growing down the stem. The folds are generally narrow and forked or branching. The name Cantharellus, meaning little cup or goblet, refers to the shape of the fungus, some of the species being so deeply depressed that a cup not unlike a tall goblet results. Cantharellus floccosus (Edible) (See Plate Facing Page 1 36) Cap or Fileus — Funnel form or trumpet shaped, depressed even into the stem. The surface of the depression is woolly or scaly. The scales some- times persist and sometimes dis- appear. Reddish yellow, fading to yellow. Gills or Lamellcz — Blunt, narrow, close; forked branched so as to appear as a network. Yellow to yellow brown. Stem or Stipe — Short, smooth, or hairy. Sometimes extending like a root among fallen leaves. Spores— ^\(\\&. i%j>4— White, thin. Time — July to September. Habitat — In groups in woods. The specimen pictured was found grow- ing in moss by a stream among laurels and rhododendrons. Section of c. floccosus GENUS AMANirOPSIS The genus Amanitopsis has white spores, the gills free from the stem, and at the base of the stem a volva, the remains of the wrapper which enclosed the young plant. There is no annulus or ring on the stem, a feature which separates the genus Amani- topsis from the genus Amanita.

The caps of the specimens found Section of A. in North Carolina varied in colour from parcivolvata (reduced) almost white to white with a red centre, and from orange or shades of orange to brilliant red. GENUS MYCENA The members of this genus have white spores ; no volva nor annulus ; lamellae thin, with acute edges ; gills with a little bay cut out near the stem, sinuate, and the stem with a cartilaginous rind. Cap membranous and striate on the margin — that is, with depressed parallel lines. Mycena haematOpoda (See Plate Facing Page 93) Cap or Fileus — Bell-shaped ; reddish brown, deeper shade on margin. Gills or Lamella — Paler tint of colour of cap ; adnate. PSr'-cI-v61-va'-' My-ce'-nS 55 Hem'-i-tSp'-S-da Fungi with Gills Stem or Stipe — Colour of cap ; hollow ; a mere tube, with thin walls.

GENUS P LEU ROT US In the genus Pleurotus the stem is attached to the cap at some point to one side of the centre. The stem may be on the very margin of the cap, or may be wanting altogether. The three species to be mentioned all grow on dead wood — either on dead trees or on dead branches of living trees. The name Pleurotus comes from a Greek word meaning side, and has reference to the position of the stem. Oyster Mushroom (Edible) Pleurotus ostreatus Cap or Pileus — Fleshy, convex, smooth, and moist. White, or tinted with ash colour or brown. Gilh or Lamella — White, or tinted with ash ; broad ; growing down the stem, and branching again and again at the base. Stem or Stipe — Short or wanting.

Spores — White, globose. Time — September to November. Habitat — Conspicuous on dead parts of standing elms. Large and white. Sometimes found on other than elm trees. GE}^US HYGROPHORUS The members of this genus maybe recognized by their moist caps and by the waxy nature of their gills, which usually grow downward on the stem (decurrent), and are not very closely placed side by side. No species is known to be dangerous. Chantarelle hygrophorus (Edible) Hygrophorus cantharellUS (See Plate Facing Page 6o) Cap or Pileus — Thin, convex at first, but later depressed.

Habitat — The speci- men photo- graphed was found growing among moss and fallen leaves in dense wood, Lake Placid. Section of H. eburneus GEl^VS ARMILLARIA The members of this genus have white spores, and the gills attached by the inner extremity to the stem. The stem has a collar, but no wrapper at the base. The name is derived from the Latin armilla, a bracelet, referring to the ring upon the stem. Honey-coloured Armillaria (Edible) Armillaria mellea Cap or Pileus — Colour from almost white to dark reddish brown. Young plants have numerous minute tufts or scales of brownish or blackish hairs. Margins sometimes striated. 1-6 inches broad. Eb-iir'-ne-iis Ar'-rall-la'-ri-a 61 Ma'-ie-a Fungi with Gills Stem or Stipe — Usually reddish brown, paler above than below. Uniform in thickness, narrowed or slightly thickened at the base. Firm externally; soft and spongy, or hollow within. 1-6 inches long. Ring or Annulus — Cottony to membranous, sometimes lacking in old plants. Gills or Lamella — Simply joined to the stem or run- ning down it. White or whitish ; sometimes va- riegated with reddish- brown spots. Spores — White, elliptical. Flesh — White or whitish. Section of A. mellea Taste unpleasant or acrid. Quality inferior. Habitat — Common in woods or in cleared land, on the ground or on decayed wood. Solitary or clustered. Time — Abundant in September. Found in June. Var. obscura has cap covered with numerous small, blackish scales. Var. flava has cap yellow or reddish yellow. Var. glabra has cap smooth. Var. radicata has tapering stem which penetrates the earth deeply. Var. bulbosa has bulbous base. Var. exannulata has cap smooth, margin even, stem tapering, annulus slight and evanescent, or wholly wanting. The Armillaria mellea has a disagreeable taste when raw, but when cooked it is thought by some to be very good. Dr. Peck says he does not know of any unwholesome species for which it may be mistaken. The Armillaria mellea has the habit, very unusual for a member of the group of Agaracales, of producing from its my- celial threads tuber-like masses of fungal substances from which the fruiting caps arise. The fungal masses of the Armillaria, the so-called sclerotia, are ribbon or string like, and may be found between the wood and bark of cone-bearing trees. These sclerotia send out cylindrical branches, called rhizomorphs, which may penetrate the soil and attack the roots of other trees, and so continue their work of destruction in the forest. 6b-scu'-r5 Gla'-bra Bai-bo'-sS Flav'-a Rid-I-ca'-ta Ex-Sn'-nu-Ia'-ta 62 SI I "a White-spored Series It is to the luminosity of tiiese mycelial threads, which per- meate the decaying wood, that the weird phosphorescent light in dense woods is due. GENUS LEPIOTA (See plate Faong page 64) The members of this genus have the gills free from the stem, and have no wrapper remains at the base of the stem. In some species the cap or pileus has the surface scaly, owing to the rup- ture of the fibres which compose it. It is this feature which has suggested the name Lepiota, from the Latin word lepis — a scale. There are about thirty species represented in the United States, of which a few are commonly eaten. Parasol Mush- room ; Tall Lepiota (Edi- ble) Lepiota procera Cap or Pileus — Con- vex, like an open umbrella. Thin, umbonate, cov- ered with closely pressed scales. 3-5 inches broad. Stem or Stipe — Long, hollow, or with cottony pith ; bulbous at the base ; usually covered with closely pressed scales. 5-10 inches long. Veil or Ring — Thick and firm ; often movable on the stem. L^p-i-o'-ta Section of L. procera Pr69'-S-ri 63 Fungi with Gills Gills or LamellcB—C\Q?,dy placed, side by side. Wliitisli, or tinged with yellow. The inner extremity remote from the stem. Spores — White, elliptical. Flesh — White, soft, and dry. Time—]\Ay to September. Habitat — Thin woods, pastures, and by roadsides. The specific name, Procera, from the Latin procera (tall), refers to the length of the stem. There is no poisonous species for which it can be mistaken if one bears in mind that it has a long stem with bulbous base, a brownish, spotted cap with dark apex, and a broad basin about the insertion of the stem. Smooth Lepiota (Edible) Lepiota naucinoides Cap or Pileus — Smooth, white ; rarely the central part of the cap is tinged with a smoky hue. 2-4 inches broad. Stem or Stipe — Coloured like the cap ; thickened at the base. Hollow or webby. 2-3 inches long. Veil or Annulus — White. Exter- nal edge generally thicker than the inner ; often mov- able on the stem. Gills or Lamellce — White when young ; when old, pinkish or smoky brown. Rounded at the inner extremity and not attached to the stem. Narrower toward the stem than in the middle. Spores — White, sub-elliptical. Flesh — Thick, white, and ten- der. Time — August — November. The smooth lepiota resembles the chalk agaric {Agaricus cretaceous), which has brown spores, and the meadow mush- Nau'-9ln-oi'-des' Section of L. naucinoides SMOOTH LEPIOTA (EDIBLE) {Lepiota nancznoides.

White-spored Series room {Agaricus campestris), which has darker gills, a persistent collar, and a stem tapering at the base. No harm can come from confusing these for edible purposes. Great care should be taken to be sure that a specimen thought to be a smooth lepiota has no volva or wrapper at the base, for the absence of a volva is the most marked difference between it and the poisonous vernal amanita (Amanita verna). The gills of the smooth lepiota turn a dingy brown or pink, and those of the vernal amanita remain white ; and the cap of the smooth lepiota has not the moist smoothness and the brilliant whiteness of the vernal amanita, Lepiota Friesii Cap or Pileus — Rather thin, convex, or nearly plain, with soft, tawny fibres forming small patches over the surface. 1-4 inches wide. Stem or Stipe — Tapering toward the cap, slightly bulbous at the base. The lower part of the stem coloured like the cap, and with similar fibrils. Hollow. Powdery white above the ring. 2-5 inches long. Ring or Annulus — Present and pendulous. Gills or Lamella — 'Narrow, crowded, free from stem ; white ; some forked. Spores — White. Flesh — Soft, white, with a slight odour when bruised. Ring or Annulus — Well developed, drooping. White above, and tawny or scaly below. Habitat — Soft, loose soil in bushy places. Time — ^July to September. GENUS MARASMIUS The genus Marasmius belongs to the white-spored series. The plants are small, and wither and shrivel in dry weather, to revive again when wet. The gills are thin, and have acute edges. The generic name comes from the same Greek word as the word marasmus, the name applied to a disease from which the patient wastes away without any apparent cause. The signifi- cance of the name will be apparent to one who watches the fleshy little plant shrink away when the sun shines. Fre'-st-I Ma-rSs'-ml-iis ? 65 Fungi with Gills Fairy-ring Mushroom (Edible) Marasmius oreades Cap or P/Zfaj— Fleshy, tough, smooth, convex, or nearly plane, often with the centre higher than the space between it and the rim. Reddish ; fading, as it ages or dries, to pale yellow or buff. 1-2 inches broad. Gills or Lamellm — Broad and wide apart, creamy or yellowish, rounded at the stem end, unequal. Stem or Stipe — Whitish, slender, tough, solid, coated with dense woolly hairs. 1-2^ inches long. Ring or Annulus — None. Spores — White. Flesh — Thin, white, tough. Time — May to October. Habitat — In circles or groups. Dangerous fungi somewhat resembling the M. oreades, and found in company with it, may be distinguished by their darh- coloured spores. GENUS COLLYBIA The members of this genus have white spores, and the lamellae with thin edges attached to the stem by their inner ex- tremity. The stem has a cartilaginous rind ; that is, it is hard and of a tough texture. The genus contains fifty-four American species, some of which are regarded as edible, while others are regarded as deleterious. The velvet-stemmed collybia, or Col- lybia velutipas, is edible, and remarkable for its habit of growing long after the frosts of winter have come. It is easily recognised by its yellowish and viscid cap, and its habit of growing in tufts, and developing on the stem a dense coat of velvety hairs. The rooted collybia, Collybia radicata, may be recognised by the char- acter of its stem, as the lower part is like a slender tap root, gener- ally penetrating the earth to a depth equal to the length of the stem above' the surface.

Time — September. Section of C. familia Habitat — The specimen photographed was found growing upon a prostrate evergreen tree near Lake Placid. GENUS PANUS (See plate facing page 145) The members of this genus are leathery plants, with the stems lateral or wanting. The gills are simple, not forked, and the spores are white. Panus stypticus is common on rotten wood, and gives out a weird, phosphorescent light. The species of the genus Panus so much resemble species of the genus Lentinus, which do not have toothed margins, that Panus and Lentinus axe considered by some as one genus, with the name Lentinus. GENUS TROGIA But one American species is reported; this is small and leathery, brownish in colour, with the spore-bearing surface white. The lamellae are obtuse on their edges, and are not hairy. The spores are white. This plant is common on fallen branches of the alder. GENUS SCHIZOPHYLLUM The members of this genus have white spores and a leathery pileus, with the lamellae hairy and grooved, or split. Schii^^o- phyllum commune is common on twigs or branches. It varies from )4 to 2 inches across, appearing as fluted shells on the bark. Fa-mil'-I-i Pa'-nus Trog'-l-a Sklz-o-phyl'-lfim C6in-mii'-ne 67 Fungi with Gills GENUS OMPHALIA The members of this genus have white spores, and the gills growing down on the stem. They have a hard, tough rind to the stem, which distinguishes them from the genus Clitocybe, which has fleshy stems. Omphalia umbellifera is a small species, with a cap about an inch broad. It is the common mushroom on the top of Mount Marcy, the highest mountain in the State of New York. GENUS RUSSULA The genus Russula may usually be recognised by its brittle character, added to its fleshy stem and the fact that the lamellse are usually joined to the stem. Bright clear reds and purplish hues prevail, but several species exhibit a green colour, or an approach to green. The spores are white or yellowish, and the flesh never exudes a milky or coloured juice. Emetic Russula (Dangerous) Russula emetica Cap or Pileus — Rosy tint to rich red. Section of R. emetica Flesh thin. The margin furrowed with parallel lines. Skin separable, somewhat viscid. Cap diameter of specimen photographed, y/a inches. Gills or Lamella — White.

At first globose, then expanded ; convex or depressed at the centre. Firm and dry. Not viscid, but adorned with flaky greenish or yellowish patches, produced by the cracking of the skin. 2-4 inches broad. Margin marked with impressed lines. Section of R. virescens Gills or Lamella — White. Moderately close ; free, or nearly so ; narrow as they approach the stem. Some forked, others not. Stem or Stipe — Shorter than the diameter of the cap. Smooth, white, and solid, or somewhat softer within. 1-2 inches long. Spores — White, rough, nearly globose. Flesh — White ; mild in taste. \r(-rSs'-5ens 69 Fungi with Gills Time — July and August. Habitat — Grassy grounds, groves, and open woods. No milky nor coloured juice, no coloured circular zones. Variable Russula (Edible) Russula heterophylla Cap or Pileus — Variable in colour. Greenish or pinkish grey, but fleshy, firm ; slightly convex, then depressed ; smooth, and polished, the very thin skin disappearing. Margin thin, smooth, or with slightly depressed lines closely placed. Stem or Stipe — Solid, firm, smooth, shining white, the apex oc- casionally dilated in the form of a cup. Annulus or Volva — None. Gills or Lamellce — Narrow, crowded, forked ; white ; of different lengths. Spores — White. Flesh — White ; mild in taste. Habitat — Woods. Common. Time — ^July to October. The specific name refers to the difference in the lengths of the gills. GENUS CLITOCYBE The members of the genus Clitocybe have the spores white, no volva nor annulus, the gills with thin edges not notched on the edge near the stem, and generally decurrent. Clitocybe laCCata (Edible) (See Plate facing Page 67) Cap or Pileus — When moist, pale red, buff red, or flesh red ; when dry, greyish to pale yellowish brown.

New Jersey. cantharellus Craterellus is at present classified as one of the family Thelephoracece. For convenience we have placed it under " Fungi with Gills." It is interesting, as it forms a connecting link between fam. Thelephoracece and fam. Agaricaceoe. GENUS AGARICUS The genus Agaricus includes all brown-spored species which have free gills and a stem with a collar. The distinctive features of several edible species may be quite satisfactorily seen by refer- ence to the table with parallel columns. Mushroom-growing is becoming quite an important industry in this country ; both professional horticulturists and amateurs successfully engage in it. It is not a difficult matter to raise the common mushroom, as the conditions necessary are easily ob- tained. Mushrooms will grow almost anywhere out of doors, and also in cellars, caves, and tunnels where a uniform and mod- erate temperature of from 50° to 60° Fahr. can be maintained. The part of a cellar devoted to mushrooms must be darkened some- what, must have a dry floor, and must be protected from wet overhead and from winds. These conditions are common in cel- lars which are rather dark, but sufficiently well ventilated not to be musty. The bed for the mushrooms is prepared in a manner Cra'-t^r-Sl'-liis Th«l-e-ph5-ra'-9e-ae A-gir'-K-ciis 73 Fungi with Gills similar to that employed in making a hot-bed, care being taken that the conditions are such that too great heat is not generated.

Section of H. sublateritium Fungi with Gills GENUS STROPHARIA There are about seven species of this genus in America. The spores are brown, there is no volva, the stem has a collar, and the lamellae are united with the stem. They have no special economic importance. GENUS PSATHYRA Two American species are reported for this genus. The spores are dark brown, there is no volva, the veil is inconspicu- ous or wanting, and the lamellae attached to the stem or notched at the inner extremity. The margin of the cap in the young plant and mature plant is always straight. GENUS PSILOCYBE Eleven American species are reported for this genus. The spores are dark brown. There is no volva, the veil is incon- spicuous or wanting, and the lamellae are attached to the stem or notched at the inner extremity. In the young plant the cap curves in at the margin. GENUS PILOSACE This genus has but one American species recorded. The spores are dark brown. There is no volva, and the veil is incon- spicuous or wanting. The lamellae are free from the stem.

GENUS EhlTOLOMA The members of this genus have pink spores, and the lamellae attached to the stem, or with a notch near the junction of gill and stem. The stem is fleshy, and not tough and hard as in Leptonia and Nolanea, genera with pink spores and adnate or sinuate lamellae. There are some twelve species in this genus, none of which have any economic interest. GENUS ECCILIA The members of the genus Eccilia have neither volva nor annulus. The gills grow downward on the stem, the spores are pink, and the stems have a hard, tough rind, not fleshy as in Clitopilus. There are three species known in America. GENUS VOLVARIA The members of the genus Volvaria are fleshy fungi, soon becoming putrescent. The spores are salmon colour. A volva is present, but no annulus. Distinguished from Amanitopsis by having salmon-coloured spores instead of white. GENUS CLITOPILUS The members of this group have neither volva nor annu- lus. The gills grow downward on the stem, the spores are pink, and the stem is fleshy, without a hard and tough rind as in Eccilia. There are fourteen American species, of which at least two species are edible. En-t8-lo'-m5 No-la'-ne-S Ec-9ll'-!(-a L«p-to'-nI-a V61-va'-ri-a. Cli-to-pi'-liis s f^ - s 5 Black-spored Series GENUS COPRINUS Ink Caps (EdibJe) The genus Coprinus may be readily recognised from the fact that the spore-bearing plates dissolve to an inky fluid soon after the spores mature. An amateur mushroom hunter may feel perfectly safe in col- lecting ink caps for his table, as all the species large enough to tempt the collector are not only edible, but are generally conceded to be of the best. Their general appearance is such that even the most un- trained observer should not mistake them for species of other groups. The oblong or nearly cylindrical cap, which does not expand until ready to dissolve in inky drops, is too striking a character- istic to permit of any one making a mistake in identifying it as a specimen safe to eat. These plants literally grow up in a night and perish in a day, as their period of growth is spent underground, and it is not until all the parts of the fruiting portions of the plants are fully developed that they push themselves above ground. Then they push and crowd from the ground in such numbers, where but a few hours before no evidence of them was seen, that each one is compressed from its cylindrical form to that of a many- sided prism, so that there would be no chance for the expansion of those within the group if it were not that those on the outer rim so rapidly expand and dissolve away. Specimens to be eaten should be gathered in the young stage and should be cooked promptly; for though not poisonous in the black stage,, they are surely not attractive. Shelley must have had the ink caps in mind when he wrote of the fungi in the garden of "The Sensitive Plant": "Their mass rotted off them flake by flake, Till the thick stalk stuck like a murderer's stake, Where rags of loose flesh yet tremble on high, Infecting th« winds that wander by." Co-prl'-ntts 89 Fungi with Gills Shaggy-mane; Horsetail; Maned Agaric (Edible) Coprinus comatus (See Pages I, V, viii) Cap or Pileus — Cylindrical or barrel-shaped; becoming bell-shaped or expanded, with split margins, when old. Colour of the buttons or young plants dark ; but that of the older forms white, flecked with dark patches or scales. Surface shaggy. 1/4-3 inches long before expansion. Stem or Stipe — White, smooth, hollow. 3-4 inches long. Ring or Annulus — Slightly adherent, or movable in the young plant ; later lying on the ground at the base of the stem, or wholly disappearing. Gills or LamellcE — Crowded. White, then tinged with pink ; finally black, and dripping an inky fluid. Spores — Black, elliptical. Flesh — Fragile, tender, digestible, with nutty flavour. Time — Autumn. Habitat — Loose, rich earth. By roadsides, in pastures, and in dumping grounds. If one study the specimens of the shaggy-mane from the time it pushes its little brown head above the ground until, as a tall black umbrella, it melts away into inky blackness, he will find much that is beautiful and interesting. A little brown button may be cut with a sharp knife through- out its length to show the unexpanded gills lying close to the part which is afterwards to become the stem. An older button cut in the same way will show the gills separated from the stem and the outer cover of the cap at the lower end of the gills joined to the stem. A still older specimen will show the connection of the outer cover broken loose from the base of the gill and the torn part still remaining on the stem as a temporary collar. The outer layer of brown threads which covers the button will be found to break as the threads within expand, and to re- main in the older specimens on the surface as patches of brown threads. Underlying these are broken white threads which in a younger stage, unbroken, formed a white cover under the brown. It is these loosely hanging threads which give the shaggy ap- pearance to the cap of the mature plants and which have suggested the names of shaggy-mane, horsetails, and comatus {comatus, in Latin, meaning hairy). C6-ma'-tfls 90 Si e 5 Black-spored Series Inky Coprinus (Edible) Coprinus atramentarius Cap or Pileus — Cylindrical at first, broadening by degrees until it is cone-shaped.

The glistening coprinus is small and beautiful, and grows in clusters on decaying woods, stumps, or buried roots. At'-rS-mSn-ta'-ri-Ss Mi-ca'-je-iis 91 Fungi with Gills GENUS GOMPHIDIUS This genus has black spores. The lamellae are waxy, and grow downward on the stem. GENUS PSATHYRELLA The members of this genus are fleshy fungi, with black spores. They have no annulus, and the lamellae are not waxy or decurrent. The cap is striate, and the stem has a hard, tough rind. GENUS PAN^OLUS There are six or more species of this genus in America. They have black ovoid spores, a cap smooth and not striate, a fleshy stem. GENUS LACTARIUS A milky or coloured juice exuding from the broken gills of a fungus marks it as a Lactarius. The species are mostly stout and fleshy, the cap resembling an inverted cone ; the gills are more or less decurrent, and the stem short and stout. Many of the species have a hot, acrid taste, and some have zones of colour on the surface of the cap. The spores are white or yellow. The juice exuded may be white or orange or blue. Peppery Lactarius (Edible) Lactarius piperatus Cap or Pileus — Creamy white, fleshy, firm, depressed in the cen- tre. Dry, never viscid, and uncommonly broad. 3-12 inches in diameter.

Time — September. Habitat — Common among mosses under fir trees. The specimen pictured was found growing in mixed woods at Lake Placid. LJg-nl-o'-tfls 93 CHAPTER VI: FUNGI WITH TEETH— HYDNACE.^ The fungi with teeth are so called because, instead of bear- ing their spores on the surface of gills and pores, they bear them on the surface of awl-shaped teeth, which project down- ward. The genera of the family Hydnacece are distinguished by the size, shape, and attachment of the teeth. Plants with teeth only, and no basal membrane, make the genus Mucronella. Plants with flattened, leaf-like teeth attached to a leathery mem- brane, growing on wood, either in the form of a cap, or simply spreading over the host, make the genus Irpex. Plants with thick, blunt, irregular spines make the genus Radulum. Fleshy or membranous plants with caps and flattened teeth, growing on the ground, make the genus Sistotrema. Plants which spread over their host, closely attached to its surface, and have simple, bristle-hke teeth, make the genus Pycnodon. Plants growing in a manner similar to those of the genus Pycnodon, but having low-crested wrinkles instead of bristles, make the genus Phlebia ; while those with smooth hemispherical warts make the genus Grandinia, and those with crested papillose warts make the genus Odontium. The typical genus Hydnum has the teeth cylindrical, so that a cross section would appear circular. This is the only large genus, and in it are found several impor- tant edible species. These may be put in two groups, one con- taining the species with a cap and central stem, and one the species growing in branched masses with no distinct cap. These are commonly known as Hedgehog Mushrooms.

Variable in colour ; light red, pale buff, or rusty yellow. Convex, plane, or deeply con- cave by the stem becoming hollow. Margins often wavy. 1-4 inches broad. Teeth or Aculei — Pointed, whitish, easily detached, leaving little cavities in the fleshy cap. Stem or Stipe — Stem solid in young specimens, hollow in older specimens. Surface rather rough ; often eccentric. 1-3 inches long. Flesh — Watery, lighter colour than cap. Spores — Whitish. Time — ^July to October. Habitat — Woods and open places. Singly or in clusters. The speci- men pictured was found in North Carolina in February. Section of H. repandum Hydnum rufescens (edible) is redder than the typical form, is smaller and more regular. White Hydnum (Edible) Hydnum albidum Cap or Pileus — White, fleshy. 1-2 inches broad. Teeth or Aculei — White, short. Stem or Stipe — White, solid, short. 1-2 inches long. Flesh— ^\\\\t.

Section of H. caput-ursi Flesh — White when young, creamy when old. Habitat — On prostrate or standing tree trunks of decaying de- ciduous trees. Erect, if on the upper side; ascending or pendulous or both, if on the side of the trunk. The bear's-head hydnum is very variable in form.

Medusa's Head (Edible) Hydnum caput-meduscB Hydnum caput-medusce has knob-like branches, with short, distorted teeth above, and long, uniform ones below. At first it is white, but later changes to a smoky or ash colour. The change in colour from white to an ashy tint distinguishes it from H. caput-ursi, which changes to creamy white. Hedgehog Hydnum (Edible) Hydnum echinaceus The hedgehog hydnum is white at first, and then creamy. The branches are knob-like, and bear numerous straight, equal teeth about two inches long. Coral Hydnum (Edible) Hydnum coralloides Plant — Pure white, becoming creamy with age. Branches and Teeth — Numerous, spreading, angular or flattened. Terminal branches often curved upwards, terminating in a crowded mass of spines. Teeth, Yd-Yi of an inch long. Stem — Short, dividing into branches almost from the base. Flesh — Tender, white, with agreeable taste. Time — ^July to October. Habitat — On prostrate trees in mountainous or hilly country. When a mere child, Elias Fries was so attracted by this beau- tiful coral-like fungus, which grew in his native forests in Sweden, that he was led to take up the study of fungi, and later became one of the most prominent students in that branch of botany, and laid the foundation for the study of the Basidiomycetes.

They are fleshy fungi of upright growth, which have their spore-bearing surface exposed on the apices of branching or simple club-like forms. Many are extremely beautiful, re- sembling corals of exquisite shades of pink, violet, yellow, or white. The seven genera are distinguished by the colour of the spores, by their habit of growth — whether simple or branched, and, if branching, by the form of the branches ; whether club- like or thread-like, flat or round, cartilaginous or leathery. Many of the members of this family are edible, and none are known to be unwholesome, so that it will be safe for a beginner to try any of them. GENUS PHYSALACRIA Plant small, simple, hollow, and enlarged at the apex. GENUS PISTILLARIA Plants conspicuous, club-shaped or thread-like, with two spicules to each spore-bearing cell. GENUS TYPHULA Plants conspicuous, club-shaped or thread-like, with four spicules to each spore-bearing cell. Ciav'-ar'-I-a'-5«-£ Phys-J- la'-cri-i PIs-tll-la-ri-a Typh'-u-li 98 f^ -s s a Genus Clavaria GENUS SPARASSIS Plants conspicuous, with tlie branciies strongly flattened or leaf-like. Sparassis crispa somewhat resembles a yellow cauliflower, and often forms masses as large as one's hand. It is considered an excellent fungus for the table. GENUS PTERULA The members of this genus are mostly slender, thread-like forms, cartilaginous when moist, and horny when dry. GENUS LACHNOCLADIUM The members of this genus are leathery plants covered with hairs. GENUS CLAVARIA The genus Clavaria is the largest genus in the family Clava- riacece. Many of the species are edible, and so easily recognised that the beginner may venture without hesitation to eat any of the branching forms. The club-like forms might be mistaken for certain club-shaped forms of the sac-fungi unless an examina- tion of the spores were made. The Clavarias would have the spores on little spicules, as in the garden mushroom, whereas the forms for which they might be mistaken would have them in membranous sacs. In collecting species of Clavaria, notes should be taken as to the character of the apices of the branches, the colour of the branches, the colour of the spores, the taste, and the place of growth. Pale Yellow Clavaria (Edible) Clavaria flava Plant — White and pale yellow. 2-5 inches high ; the mass of branches 2-5 inches wide.

CSv'-l-pes P6-r6'-stts De-^p'-J-Sns Pa-Ifis'-tSr PJc'-ttts 103 Fungi with Pores — Boletaces GENUS BOLETUS The species in the genus Boletus are numerous, and many are extremely beautiful. They are distinguished from the other pore-bearing fungi by the fact that their tubes are easily separable from each other and from the portion on which they are borne. They are to be looked for in the warmest part of the season, and with a few exceptions will be found on the ground. As it is difficult to dry specimens so that they will retain their size, shape, and colour, careful notes should be taken of these points, together with the colour of the spores, the colour of the tubes, the colour of the flesh before and after being bruised, the char- acter of the stem, the presence or absence of hairs and fibres on the several parts of the plant. The genus Boletus contains many edible species, and also many which are dangerous ; and as the recognition of the different species is a difficult matter, even for experts, the beginner should be especially cautious. In general it will be well to avoid for edible purposes all Boleti which change colour on exposure to the air or on being pressed; all those which have red-mouthed tubes, or mouths of a deeper colour than the rest of the tube ; and all those with a peppery or acrid taste. Experiment cautiously with the other species. A detailed description of the species is out of the question in this book; for such the reader must refer to " Boleti of the United States,"* or to " Filhrer fur Pilzfreunde."t Boletus glabellas Cap — Smoky yellow. Flesh — White, changing to blue when wounded. Tubes — Brownish yellow tinged with green, changing to blue when wounded.

POLYPORACEy^ The fungi with pores permanently united to the surrounding tissue and to each other form a large and important group, the Polyporacece. With but few exceptions they are leathery, corky, membranous, or woody. Nearly six hundred species have been reported from America. Ed'-u-lls Sflb'-to-mSn-to'-sus A-mgr'-i-ca'-niis P6'-ly-p6-ra-9S-£e 109 Fungi with Pores — Polyporaces GENUS MERULIUS Merulius lacrymans The simplest of these Polyporacece is the dry-rot fungus, Merulius lacrymans. The food-seeking portion consists of fine white threads, mycelium, which penetrate the woodwork of buildings, causing it to crumble to dust. The fruiting portion consists of flat, irregular bodies whose under surface bears the spores in shallow pits separated by narrow ridges. Water is excreted from these flat disks, which, from the habit of dropping like tears, has suggested the specific name lacrymans, from the Latin lacrymare, to weep. GENUS POLYPORUS The genus Polyporus and the genus Trametes have the pores closely packed and united to together. In Trametes the uniting substance is the same as the substance of the cap, but in Poly- porus the uniting substance is different frorn the substance of the cap. The genus Polyporus in its widest sense is a large, one, numbering some five hundred species, and containing every texture from fleshy or pulpy to woody. The fruiting portion is often seen in the form of brackets shelving out from standing or fallen trees. The mycelium pene- trates the wood, softening it, and causing it to crumble, so that in the course of time the tree dies. The external evidence that the tree has been attacked is the appearance of the fruiting por- tion, which often attains a very great size. Elfvingia (polyporus) megaloma Polyporus megaloma is attractive to frequenters of the woods, as its spore surface when fresh is soft and white, and furnishes an attractive surface for stencil drawings. Elfvingia (polyporus) fomentaria The brackets of Elfvingia fomentaria resemble horses' hoofs.

See p. no Genus Polyponis German tinder, which, in the form of sticks or fusees, commonly known as punk, is used for hghting cigars and pipes in the wind, or for touching off fireworks. The fusees are made by beating the fungus substance until it is flexible, and then dipping it into saltpetre, Polyporus conchatus Polyporus conchatus is a beautiful species found on the under side of fallen trees, growing in such a manner that from the spore-bearing surface the shells look like rosettes of shim- mering golden-brown velvet. Polyporus velutinus Polyporus velutinus is common in the form of stiff ruffles with white or creamy spore surface, and grey or tan-coloured plush-like upper surface. Polyporus pergamenus Polyporus pergamenus has a somewhat bristle-like, tan- coloured spore surface, and a velvety drab upper surface, often tinged with green from a green alga which grows upon it. Polyporus perennis Polyporus perennis resembles a slender-stemmed goblet. Polyporus sulphureus Polyporus sulphureus is an edible fleshy form. It grows in clusters, the stemless caps often five or six inches broad and overlapping. The colour of the young cap is yellowish red or pale orange, with the margin wavy, and of a beautiful yellow. It is soft and juicy, and often — when cut — exudes a yellow juice. The plants may be found on the dead wood of trees during showery weather from May to October. The mature plants become dry and crumbling, and as they dry they lose Con-cha'-tiis V£l-u'-tl-nus Per-ga-me'-nfis Per-en'-nis Sul-phu'-re-us III Fungi with Pores— Polyporacese their attractive colours.

Polyporus squamosus Polyporus squamosus is found often on decayed ash trees and sometimes on others. The cap has a thick lateral dark stem and is pale yellow tinged with brown, and covered with dark scales. It is reported to have been found seven feet in circumference, with a weight of forty-two pounds, and that it attained this growth in the short time of four weeks. Polyporus lucidus Polyporus lucidus has a lateral stem which, with all but the margin of the cap, is highly polished, as if varnished, and is in colour a rich mahogany brown.

Polyporus versicolor* Polyporus versicolor has a leathery cap, thin and rigid, plane, depressed at the attached portion, velvety, shining with varie- gated two-coloured zones. The pores are minute, round, with acute and ragged edges. White, then yellowish. It is common on decaying tree trunks and upon telegraph poles.

The caps are thick, round, without zones, velvety, and of a rusty-yellow colour. The lower surfaces of the caps, with the stems are woody and corky, but the upper surfaces of the caps are soft and woolly. The stem is swollen and covered with yellow wool. The pores are decurrent, minute, and un- broken, and of a dusky grey colour. This is a handsome species, especially remarkable for its double cap. The stem is an inch long and almost equally thick. The cap is three to four inches wide, and the flesh is uniform in colour. GENUS TRAMETES Trametes pint is brown, and grows on pines and other cone- bearing trees. Trametes cinnabarina is bright red, and common on birch and cherry. Trametes suaveolens is white, and grows on willows.

Sordid white. This fungus, in the form of brackets, is found espe- cially on birch trees, but it is also found on various other kinds. It is a wide- spread species, and is quite variable. The lamellse are at first thick white; then thinner, with acute edges.

GENUS D/EDALEA The genus Dcedalea has the spore-bearing surface in the form of winding and labyrinthine lamellae, so that instead of pores there are irregular branching slits on the under surface. These fungi are normally sessile, woody, and hard. Dsedalea unicolor Dcedalea unicolor is in form like a full leather ruffle with scalloped edge, so full that the scallops overlap. The branching slits are very minute, and the upper side is in zones of tan colour, with a plush-like surface. The zones are often tinged with blue or green from algse which grow upon them. Daedalea confragosa Dcedalea confragosa has a rough grey upper surface, and grows from the centre in the form of depressed sessile caps. The texture is firm and leathery. Daedalea quercina Dcedalea quercina is a woody or corky species, rugged, and without zones on the surface. At first it is porous ; then, by the breaking down of the walls of the pores, slits are formed, with blunt partitions. It is common on oak trees.

It is this resemblance to an ear which has suggested the names, Jew's ear and Judas's ear. Its habit of growing on elder has given rise to the belief that Judas Iscariot hanged himself on this tree. This fungus is prized by the Chinese as an article of food, and is imported by them from the South Sea Islands. Its manner of bearing the spores on basidia places it in Class III, Basidiomycetes, which contains fungi with gills, teeth, and pores. Tremellodon Tremellodon is a clear fungus, which in colour resembles a piece of water-soaked snow, but in form resembles a Hydniim, as it has teeth-like projections on the under surface. Guepinia Guepina is a bright yellow fungus, about an inch high, in form like little spatules or goblets. It is common in cracks of logs and stumps.

CHAPTER X: OFFENSIVE FUNGI— ORDER PHALLALES The Phallales are all terrestrial fungi ; that is, they are found growing on the ground, and not on logs and trees. They are in- teresting, but too offensive to attract any but the most coura- geous students. They are more common in the South than in the North, where they make themselves too conspicuous by their intoler- able odour. They are structurally different from the other pouch-fungi, the puffballs, in that they do not retain their spores in the skin (pe- ridium) until they are fully mature, but send them into the light, exposed on a quickly deliquescing jelly-like mass, the gleba. The order may conveniently be divided into two families: ( Receptacle latticed, sessile, or stalked. FAMILY I. CLATHRACE/€ \ Spore mass borne on the inner sur- ' face of the receptacle. ( Receptacle tubular or cylindric, with a FAMILY II. PHALLACE/E j Cap. ( Spore mass on the surface of the cap. GENUS PHALLUS Stinkhorns The genus Phallus may be readily distinguished by the cylindrical shape of the spore receptacles and the intolerable odour. No one with his sense of smell developed would think of eating the members of this group. The botanist and the artist, however, have braved this lion on his own territory, and have found much that is beautiful and interesting ; the artist having the advantage in his task of portraying the handsome specimen, Phai-la-les Clith-ra'-ce-s Phai-la'-9e--E Phal-lus 117 OfTensive Fungi in that he can inclose it in a sealed glass case and work in comfort. The experience of the botanist must be realised to be appreciated. An overpowering fetid odour suddenly evident upon the premises has many times filled with consternation the guests at summer resorts, causing among them much speculation, with suggestions of bad sewerage, and carelessness on the part of their host, together with other comments equally disastrous to the reputation of the place. The distracted householder searches in vain for a solution of the difficulty, and the odour disappears as mysteriously as it came. If he is one of the initiated, however, he will search until he finds the haunt of the offender, and will destroy all chance of a repeti- tion of the nuisance — for one summer, at least. The mischief-maker is a handsome specimen, as its plate shows. The white stem, bearing at its summit a mass of gela- tinous green substance capped with a yellow-white ring, and emitting its intolerable odour, has surely come into existence for a purpose — a purpose soon suggested — as hundreds of flies wing their way hither to sip the semi-fluid mass. The botanist tells us that the spores of this plant are mixed in the green fluid, and that they are carried away on the feet and in the bodies of the flies to other places, where new colonies may be started. The plant has undoubtedly emerged from the ground for the sole purpose of disseminating its spores, and all its parts have been developed to accomplish this function in the most effectual manner. The banquet for the flies is prepared underground, and the table, with its viands all ready, is pushed into the light, while the invitation to the guests is wafted swiftly on the breeze. One is curious to learn the mechanism by which so much is accomplished in apparently so short a time, and finds in this instance, as in all others where great things are accomplished with ease, that many forces have been slowly at work to insure everything being in readiness for the success of a final flourish. A search underground shows the mycelial threads to have per- meated the soil for many feet in every direction in search of building material, and a glance at a vertical section of one of the pink eggs which has pushed its way out of the soil will show ii8 Genus Phallus in outline tlie plan of what is to be. The pink "eggshell," or peridium, is lined with a jelly-like substance, which has un- doubtedly Pink^ eggshell Future jreen mass of Cap Jelly-like 6ub5tance Future stem Compressed cells served as a safe packing to what is within, a protection against blows and insect rav- ages. Within this coat, in section, ap- pears as two dark - col- oured saddle-bags that which later is to form the green mass on the cap of the fully developed spore table. Between these dark masses lies in section the future stem ; it is hollow, and bears on its rim the spore-bearing cap. The walls of this cap consist of flattened cells, which by extraordinary growth and expansion are to force the stem through the eggshell and carry the banquet of spores several inches into the light, leaving the torn wrapper as a volva at its base, a natural "Jack-in-the-box."

It is thought that this delicate white network, which hangs lilie a lace skirt below the cap, renders the fungus additionally conspicuous after dark, thus attracting the night moths and other night-flying insects.

The volva ruptures, and the receptacle issues in a similar manner. The members of this family have the spore receptacle latticed or branched instead of tubular or cylindrical, and bear the spores on the inner surface of the receptacle rather than on the outer surface.

Col- lectively, the closed chambers are called the gleba, and this gleba is surrounded by a definite rind (peridium), which, in different puffballs, has various and characteristic ways of opening to per- mit the spores to escape. The different ways in which the rinds (peridia) open are explained under the separate examples of the pouch fungi — puffballs, earth-stars, stinkhorns, birds' nests, and calostomas. The Lycoperdales, known in different parts of the country as smokeballs, devil's snuffboxes, puffballs, etc., have their spores enclosed until maturity in closed chambers, surrounded by a con- tinuous skin or peridium. They spend most of their lifetime underground, getting their food from decaying vegetable matter, and are for this reason called subterranean saprophytes. When they are about ready to scatter their spores, they emerge from the ground, and are then to be seen in pastures, and on fallen logs in woods and along roadsides. Every country child has pinched them to see the " smoke" rise, little knowing that he was doing for the puffball just that for which it had come into existence — scattering its spores far and wide to grow into new plants. The plants of the puffballs, the mycelial threads, form an extensive network of white threads in the decaying vegetable matter in which they grow ; then little balls appear on the white threads, as in the Agaricales, with the difference that they in- crease in size without forming gills and stem. The balls have a fleshy interior, cheesy and white at first, but afterwards yel- lowish or pinkish, gradually darkening until the whole or a part Ly'-co-pSr-da'-Ies 123 Puffballs of the fleshy interior becomes filled with dust-like spores, when the rind of the ball breaks to let the spores escape. Sometimes the wall breaks off in scales ; sometimes it is punctured at the summit with one hole, sometimes with several, and sometimes it splits and turns back to form a star on the ground. Sometimes the balls contain elastic threads (capillitium), which help to push out the spores, and sometimes they do not. Sometimes there are threads massed at the base without spores in them, so that they form a sterile base or sterile subgleba, and sometimes the threads are massed to form a central column (columella) in the interior of the ball. These characters, with others, form the basis on which the puffballs are separated into the genera Lycoperdon, Geaster, Calvatia, Bovistella, Bovista, and Calostoma. GENUS LYCOPERDON The Lycoperdons, or true puffballs, produce within the ball vast numbers of dust-like spores mingled with elastic threads. When the ball is compressed, the rind or peridium bursts at the summit to form a single mouth, and the elastic threads cause the spores to fly out in puffs like smoke. The spore-bearing part of the plant is globe-shaped, obovoid, or top-shaped, and at the base of the gleba no spores are pro- duced ; the cells here are coarse and empty. The rind or peridium of the ball con- sists of two parts, the outer bark or outer peridium being adorned with spines or scales or warts or gran- ules. Sometimes the exterior coat may be peeled off, sometimes it dries and falls away in fragments. The inner coat is thin and papery, and opens on the top with one opening. At first the ball is fleshy within, the microscope showing the flesh to con- sist of a great number of simple or branched threads and enlarged cells. The enlarged cells bear usually four Ly'-c6-pgr'-d6n 124 Lycoperdon Sterile base Section of Lycoperdon (diagrammatic) m 2; S, *»«* Genus Lycoperdon spicules, on the tips of which are the spores. When the plant is fully developed, the fleshy part becomes so filled with moisture that water may be squeezed out as from a sponge. As the flesh becomes moist, the colour changes from white, through yellow, to olive. After the change in colour, the wet mass becomes dry and powdery, a mass of globose spores and elastic threads or capillitium. The Lycoperdons are of small size, usually found in fields and woods. A section made by cutting a ball from top to base will show that the threads form a more or less well developed sterile base or subgleba underneath the fertile gleba, or mass of threads containing spores. Sometimes the sterile threads from the base rise upward in the centre of the fertile mass and form a little column, the columella. Usually the threads which bear the spores are in two sets ; one set extending inward from the walls of the rind, and another set extending outward from the central columella. Pear-shaped Puffball (Edible) Lycoperdon pyriforme Peridium or Pouch — Pear-shaped. Dingy white or brownish, with mycelium of long, white, branching fibres. Diameter ^-i % inches. Height 1-2 inches. Bark or Outer Coat — Thin ; of minute, often persistent, scales or granules, or short, stout spinules. Whitish grey or brownish. Inner Coat — Smooth, papery, whitish grey or brownish, opening by apical mouth. Subgleba — Small, white, quite compact, the cells minute. Columella — Present. Spores — Globose, even, greenish yellow to brownish olive. Threads — Branched, long, forming a dense tuft in the centre. Time — July to October. Habitat — On old timber or on the ground, in groups sometimes several feet across in extent. The commonest of puffballs, and found throughout the world. Pinkish Puffball (Edible) Lycoperdon subincarnatum (See Plate Facikg Paoe 134) Peridium or Pouch — Globe-shaped, sessile, without a stem-like base. Rarely over one inch in diameter. Py'-ri-f6r'-m^ Sub-In'-car-na'-tiim I2S Puffballs Bark or Outer C(7(7/— Pinkish brown, with minute short, stout spin- ules, which fall away at maturity. Inner Coat — Ash coloured.

Spores and Capillitium — Spores round, minutely warted. Greenish yellow, then brownish olive. Threads long, simple, and transparent. Time — August to October. Habitat — Old trunks in woods. GE}^US CALVATIA The Calvatias are puffballs of large size, all with thick cord- like mycelium rooting from the base. They all eject their spores through irregular openings in the upper part of the peridium, and they all have a d e n se network of branching threads (capillitium) traversing the tissues ofthespore- bearing por- t io n, the gleba. These threads are elastic, and project the spores from the rind or case as they twist and turn. The sterile portion, the subgleba, is definitely limited and concave above. Sterile base Calvatia Section of Calvatia Brain-shaped Calvatia (Edible) Calvatia craniformis Peridium or Pouch — Very large, obovoid or top-shaped, depressed above.

Genus Calvatia wrinkling to resemble somewhat the surface of the brain, whence its name craniformis. Inner Coat — Thin, ochreous to bright brown, velvety, extremely fragile. The upper part breaks into fragments. Subgleba — Occupies half the peridium ; cup-shaped above, per- sistent. Spores — Greenish yellow, then olivaceous. Globose, even, with minute pedicel. Threads — Long. Habitat— On ground in woods. Giant Puffball (Edible) Calvatia maxima Peridium or Pouch — Very large, 8-15 inches in diameter, or larger. Globose, depressed globose, or obovoid, with a thick cord- like root. Park or Outer Cca/— Flocculous or nearly smooth, thin, and fragile. White or greyish, becoming yellowish or brown; usually remaining closely adherent to the inner coat. Inner Coat — Thin and fragile after maturity, breaking up into fragments. Subgkba — Shallow or none. Spores and Threads — Greenish yellow, then brownish olive. Spores globose, threads long and branched. Time — August to September. Habitat— Gra.5sy places. Calvatia maxima has been known as Lycoperdon giganteum, and also as Lycoperdon maxima. It has been transferred from the genus Lycoperdon to the genus Calvatia because it ruptures the peridium irregularly to discharge its spores, instead of form- ing a small hole at the apex, as other Lycoperdons do. It is asserted on good authority that the giant puffball has been found with a diameter of three feet and a weight of forty- seven pounds. The giant puffball is considered by many as a choice article of food when the flesh is white. It is said that if the flesh of a growing puffball is cut or injured the wounds will fill up with new tissue. It will be interesting for some one to try this experiment. In the days before matches came into use, the dry, spongy threads were used as tinder to catch the sparks which flew from the flint-stone when it was struck for fire, and the spore-dust was used to stanch the flow of blood. 127 Puffballs Cup-shaped Puffball (Edible) Calvatia cyathiformis Peridium — Large, top-shaped. Bark or Outer Coat — Thin, adherent, smooth, and continuous, easily peeling off. Inner Coat — Pale to dark purple, loosely woven, fragile at matur- ity, breaking up into fragments from above downward. Subgleba — Short and. thick, with cord-like root, persistent, cup- shaped, occupying }4->^ the peridium. Spores and Threads — Violet to dark purple. Spores globose and warted, threads long. Time — August to October. Habitat — On the ground in meadows and pastures. The old name was Lycoperdon cyathiforme. Cyathiforme, meaning cup-shaped, is suggested by the cup-like base which remains after the dispersion of the spores and threads (capillitium). GENUS BOFISTA In the genus Bovista the rind or peridium opens by an apical mouth, as do the species of Lycoperdon, but the species of Bovista have no sterile base. They are puff- balls of small size, growing in fields and woods. The outer coat is thin and fragile, and scales off at maturity. The inner coat is thin, becoming papery, and then opens by an apical mouth. Bovista plumbea is esteemed a delicacy. It is shaped like a flattened globe, with a smooth, white inner coat, and a lead- coloured outer coat opening by an apical mouth.

GENUS GEASTER Earth-stars The Geasters or Earth-stars are the most picturesque forms of the putfballs. At first they are sunk deep in the soil, and are connected with it by abundant thread-like mycelium, which issues from every part of the surface. In the earth-stars the covering to the pouch is double, the outer cover is thick and leathery, and at first closely invests the inner coat, but is separate from it. At maturity the outer coat breaks its connection with the mycelium in the soil and bursts to form separate lobes, which become reflexed and lift the inner ball from the ground into the air, where it remains, seated at the centre of the expanded star- B6-vIs-t«l'-m O-hi-^n'-sls Ge-Ss'-tSr 9 129 Puff balls like coat. The coat of this ball is thin and papery, and opens by one apical mouth. The threads or capillitium, which bear the spores, project from the tissue of the inner wall and also from a central columella. The Geasters have no economic value, but are rather inter- esting to the nature student on account of their beauty and their curious methods of discharging their spores. The Smallest Earth-star Geaster minimus Peridium or Pouch — Globose, depressed, not pointed; vaulted underneath. Bark or Outer Cd>a/— Segments acute at the apex, many lobed ; the lobes, seven to nine, expanding ^-i inch. Inner Coat — Ovoid, y^-\ inch in diameter, white to pale brown, with a distinct pedicel, seated in a plain circular disk. Mouth — Lifted on a cone, lip bordered with hair-like fringe. Spores — Brown, globe-shaped, minutely warted. Threads — Transparent. Habitat — Grassy grounds. Water-measuring Earth-star Geaster hygrometricus Peridium or Pouch — Sub-globose, depressed, the bark or skin fall- ing with the mycelium. Bark or Outer Coat — Deeply parted ; the segments, acute at the apex, seven to twenty. Strongly hygrometric, expanding to a breadth of 2-3 inches. Inner Coat — Globose, depressed, sessile, covered with a network. Whitish or greyish. Mouth — Rim irregular. Spores — Brown, globe-shaped, minutely warted. Threads — Transparent, much branched and interwoven ; continu- ous with the hyphse or threads of the inner coat. Habitat — Fields and woods, in sandy soil. The Geaster hygrometricus, or Astrceus hygrometricus as it is called by some, is found all over the world. When the Mln'-l-miis Hy'-gr6-m^t'-ri-cus 130 LEAST EARTH-STAR {Geasier minimus, Schw.

It is a fair-weather traveller, always resting at night and on damp days. GENUS COLOSTOMA This genus has but three known American species. The plants are remarkable in structure and substance. The spore mass or gleba lies at the centre of a base, and is in its young stages surrounded by four layers. The outermost coat is gelati- nous, and soon disappears. This is known as the volva or wrapper. The layer just within the wrapper also soon disap- pears ; it is known as the exoperidium. The layer just within the exoperidium is known as the endoperidlum, and is the layer seen on the exterior of older specimens. Between the exope- ridium and endoperidium is a layer of red threads, part of which is torn away when the exoperidium breaks, and a part of which remains as a red star at the apex of the ball. The exoperidium is cartilaginous ; it is thin and fragile when dry, but when wet it is flexible, translucent, and soft. The endoperidium is hard and rigid when dry, and is conspicuous for the brilliant red which shows at its mouth. Within the endo- peridium is a sac which contains the spores ; when the spores are mature, this sac contracts, and forces the spores out into the air. The mycelium, or vegetative part of the Calostoma plant, is composed of numerous cord-like fibres, translucent, jelly-like, and tough, which, branching and anastomosing into a dense net- work, form a rooting columnar base to the spore-bearing part of the plant. The name Calostoma means beautiful mouth, referring to the red star which surrounds the opening through which the spores escape. Cai-6s'-t6-mS 131 Puffballs Calostoma lutescens Ball or Peridium — Globular, with a thick, entangled, rooting base. Outer Coat or Exoperidium — Dingy yellow, rupturing so as to form a ragged collar at the base, a thin cap on the summit, and small fragments between. The cap is marked on the under side with a vermilion star outlined with yellow. Inner Coat or Endoperidium — Smooth, globular. Pale yellow. Mouth — With several rays of a bright red colour. Footstalk — Thick, of entangled strands finer than those of C. cin- nabarinum. Stem long, yellowish green. Spores — Globular, with protuberances. Calostoma Ravenelil Bailor Peridium — Globular, with a thick, entangled, rooting base. Outer Coat or Exoperidium — Cartilaginous, gelatinous. Fragments remain upon the inner coat in the form of irregular warts or scales. Inner Coat or Endoperidium — Yellowish. Tough when wet, rigid when dry. Mouth — Red starred. Footstalk — Short and rooting, composed of mycelial threads netted to form cartilaginous cords. Spores — Elliptical, oblong, smooth. Calostoma cinnabarinum Outer Coat or Exoperidium — Vermilion within, breaking at the base and sometimes at the apex. Inner Coat or Endoperidium — Yellowish, often slightly vermilion. Smooth. Mouth — Rays several. Vermilion. Footstalk — Reddish brown or brownish. Spores — Elliptical oblong,, spined or punctured, pale ochre yellow.

See page 138. Genus Scleroderma ORDER NIDULARIALES The members of this order, Nidulariales, or bird's-nest fungi, are curious fungi of small size. They resemble, when mature, tiny birds' nests containing eggs, as the pouch in which the spores are developed opens at the top to form a nest or bowl or trumpet, and the globular cases in which the spores are contained have strong walls, and remain in the open pouch like eggs in a nest. One genus of the order, Sphcerobolus, has two walls or layers to its nest and but one spore case or "egg." This "egg" is jelly-like, and is forcibly thrown from the nest when the spores in it are mature. While a part of this action is due to the mechan- ical working of the teeth, it is thought that underneath the spore case gases are formed which expand, and so help force out the "egg." The other genera have but one wall to their nests. The genus Nidularia has ragged edges, the genus Cyathus is trumpet- shaped, and the genus Crucibulum is bowl-shaped. ORDER SCLERODERMA TALES The puffballs of the order Sclerodermatales have the rind or peridium thick. The spores remain in the peridium until maturity, when they escape from an irregular opening in the rind. The species are not numerous, but some are abundant and widely distributed. GENUS SCLERODERMA The species of the genus Scleroderma, or thick-skinned puff- balls, represent a transition from the subterranean forms to those which emerge from the ground and have a definite opening from which they eject their spores. To illustrate : there is one group {Hymenogastrales) in which the species remain in the ground, NW-u-ia'-ri-a'-les NM-u-ia'-rl-i Cru-9Yb'-u-lura ScI«r-6-dSr'-ma Sphe-r6b'-6-lus 5y'-^-thiis Scler'-6-dgr'-mS-ta'-les 133 Puffballs even when mature, unless washed out by rains or nosed out by animals, and which rely upon being crushed by accident or upon the disintegration of their rinds to free their spores. All true puff- balls push themselves out of the ground before the spores are mature, and then, by rupturing the skin in a definite manner when mature, disperse their spores. The thick-skinned puff- ball goes a step farther than the first mentioned and emerges from the ground ; but it remains behind the true puffballs, which disperse their spores from a definite opening, for it ruptures the skin irregularly. Scleroderma vulgare (Edible) Peridium or Pouch — Rough and warty; depressed, globose. Pinkish to buff, remaining solid until the fungus is quite old. Sessile or with a rooting base. Ruptures irregularly to scatter the spores. Subgleba — None. Spore Mass — Lead colour marbled with white. Habitat^Old stumps and buried roots. This fungus has been eaten without harm, but is pronounced very unattractive. Viil-ga'-re Section of S. vulgare «34 FLESH-COLOURED PUFFBALL (EDIBLE) {Lycoperdon subincarnatum.

These asci are, as a rule, collected, together with slender empty asci, called para- physes, in variously shaped bodies, known in different orders by different names, such as perithecium, ascoma, apothecium, and receptacle. This class includes in its numbers individuals ranging in size from microscopic one- celled plants to conspicuous and often beautiful specimens. We shall con- cern ourselves with but a few of those conspicuous ones which are attractive either from an edible or an artistic standpoint. Asci and paraphyses ORDER TUBERALES— TRUFFLES The order Tuberales contains the truffles, which are subter- ranean fungi, ranging in size from an acorn to a good-sized po- tato. The asci or spore-sacs are formed on the inte- rior of the fungus, the warty truffle itself being called an as- coma, as it contains the asci. Since the time of Pliny and Dioscorides, truffles have been known and esteemed as a table delicacy. Since they mature As'-c6-my-ce'-tes Tu'-b^r-a'-les 135 Section to show position of asci TrufHes, ascoma Spore-sac Fungi — Ascomycetes underground, they must be hunted for by dogs and pigs trained for the purpose. A pig will scent a truffle at a distance of twenty feet, and will run quickly to the spot to dig it out with her snout. An attendant must follow the pig to secure the truffle before the pig eats it. Edible species have not been found growing in this country. ORDER HYPOCREALES The order Hypocreales contains certain fungi which are parasitic on other fungi, and also on insects. In the genus Cordyceps there is a club-like form about an inch long, and of a rich red colour, which lives as a parasite on the pupae of various moths buried beneath dead leaves. In New Zealand a similar fungus lives on caterpillars. The mycelium in time replaces the body, but maintains out- wardly the form and appearance of the caterpillar. These growths are much prized by the natives as food. The form which grows on the truifle-like Elaphomyces is shown in the species of Elaphomyces upon which the Cordy- ceps lives as a parasite grow two or three inches below the surface of the ground, and somewhat resembles a truffle in appearance. ORDER SPHERULES (See Plate Facing Page 1 16) The Xylaria pictured is a woody fungus which is common, growing on logs or at the bases of trees or stumps. The collections of asci {perithecia) are fully im- bedded in the fleshy part of the fungus {stroma), which is formed almost wholly of Fungus growing on caterpillar hardened mycelium.

See Genus, p. 116 Order Pezizales— Cup Fungi ORDER PEZIZALES-CUP FUNGI The Pes^iiales or cup fungi, which are typically disk or cup- shape, comprise an extensive group, and vary in size from forms scarcely visible to the naked eye to forms several inches in diameter. One genus, Pe:{iia, has a smooth ascomata, regularly saucer-shaped or cup-shaped. The genus contains many species which are met with chiefly on decaying vegetable matter. The spore-sacs are situated on the upper surfaces of the cups, and the spores are ejected with such force and in such profusion that they form a cloud around the plant from which they are expelled. Peitia ceruginosa is a stalked green form, and is interesting because it permeates the wood of oaks and beeches with its mycelium, and gives a rich green colour to the wood, which makes it valuable for the manufacture of the famous "Tunbridge ware." One may often find the wood affected when the fruit cups are not evident. Pe^i:{a Willkommii produces on larch trees a disease known as the "larch canker," which shows itself as a sunken, blistered hole from which resin flows. This patch is formed because the mycelium of the fungus attacks and destroys the cambium or green layer which lies under the brown bark, and since this is the tissue which builds up the wood of the trees, the growth of wood in this part is prevented. The fruits appear above the bark in the form of little cups, white outside and scarlet within. When branches bearing golden-yellow needles are seen among the fresh green shoots of a larch, pre- maturely giving to the tree an autumnal appearance, one may expect to find Pe\i:{a Willkommii at work. Peziza odorata (Edible) Cup — Yellowish, translucent, becoming dull brown when old. The flesh is moist and watery, and separable into two layers; the outer layer rough, and the inner smooth. The frame is cup-shaped when young, but flattened and split on the mar- gin when old. E'-ru-gKn-o'-sS Wll-kdm'-M 6'-d8r-a'-ti Section to show two layers 137 Spore-sac Fungi — Ascomycetes Stem — None. Habitat— 'Wit specimen pictured was found in December, among the violets in a cold frame in New Jersey. Golden Peziza (Edible) PeT^i^a aurantia Cup — Orange red within, golden or whitish outside, with a frosted appearance. Subsessile, irregular. Habitat — In clusters on the ground, usually in the autumn. ORDER HELVELLALES—EAR TH- TONGUES The order Helvellales contains the fleshy spore-sac fungi which have the spore-bearing body, the ascoma, open from the earliest stage of its development. FAMILY GEOGLOSSACEyE The family Geoglossacece, which belongs to this order, con- tains the earth-tongues, which are club-like forms, green or black or yellow, and from one to three inches high, common on the ground, growing in rich wood mould. In consistency they are fleshy, gelatinous, or waxy, and their asci open by means of a terminal pore. GENUS SPATHULARIA The genus Spathularta has the spore body flattened and growing down both sides of the stem. Velvety Spathularia Spathularta velutipes (See Plate Facing Page 132) Spore 5^4-— Flattened, tawny yellow, shaped like a spatula, with the spore surface wavy and growing down two sides of the stem. Stem — Hollow, minutely velvety, dark brown tinged with yellow. Flesh — Firm and tough, shrinking little in drying. Habitat — Mossy trunks in damp woods.

Genus Vibrlssea Spathularia clavata Spore Body — Clear yellow, shaped like a spatula, sometimes tinged with red. Obtuse or cleft at the apex, the surface wavy, the margin crisped, growing down the stem some distance on opposite sides ; hollow. Stem — Thick, hollow. White, often becoming yellowish. i?-/«A— Dry. GEhlUS GEOGLOSSUM The genus Geoglossum has the spore body simple, erect, and club-shaped, and entirely black. The spore surface is ter- minal. Geoglossum hirsutum Geoglossum hirsutum is black, dry, and everywhere velvety. Lanceolate, ovate, oblong, or almost round, often irregular. The spore-bearing portion is one-quarter to one-half the length of the fungus. Geoglossum glabrum Geoglossum glabrum is dry, black, or brownish black, some- times tinged with olive or purple. Club-shaped or sometimes laterally compressed. The spore-bearing portion not sharply distinct from the stem below. GENUS VIBRISSEA The genus Vibrissea contains fungi with vertical and simple stems, and horizontal caps with their thick margins rolled in to- ward the stem. The spore-sacs are borne on the upper surface. Vibrissea truncorum Vibrissea truncorum Is a clear orange-red or sometimes yel- low or brownish-red fungus, about an inch high, found on decayed wood, branches, or leaves which are submerged in water.

The stem is long, pallid, or reddish. The plant is found chiefly in pine woods. GENUS MITRULA The genus Mitrula has the spore body erect, black or bright coloured, and dry, spatulate, or cylindrical, often compressed lat- erally. The spore-bearing surface is sharply distinct from the scaly or mealy stem below. Irreg-ular Mitrula (Edible) Mitrula vitellina, var. irregularis * Spore Body — Bright egg yellow. Club-shaped, somewhat lobed, cylindrical or compressed ; apex narrow, obtuse, smooth. No two plants are quite alike. Length, 1-2 inches. Stem — Short, white, rather distinct, covered with fibres. Spongy and white within. Habitat — In mossy places in woods during the autumn. The specimen pictured was found growing among fallen birch leaves, hemlock needles, and moss, in the dense woods at Lake Placid. FAMIL Y HELVELLACE/E— MORELS A second family Helvellacece contains three important gen- era, Morchella, Gyromitra, and Helvella, in which are the largest and most highly prized spore-sac fungi known. They are dis- tinguished from the earth-tongues by the cap-like form of the spore body or ascoma, but especially by the character of the spore-sac, which opens by a little lid instead of by a simple pore.

Genus Morchella GENUS GYROMITRA The genus Gyromitra contains seven species. These have the ascomata distinctly stalked, and the upper surface covered with gyrose folds. The largest spore-sac fungi belong in this genus. Gyromitra esculenta (Edible) Cap — Bay red, round, lobed, irregular, gyrose-wrinkled, attached to the stem in several places. Hollow, white, and uneven within. Stem — Whitish, hollow, scurfy. Two or more inches long. Flesh — Edible only when young and freshly gathered. Habitat — In sandy soil, during the wet weather of May and June. G. esculenta M. deliciosa Section to show margin of the cap united to the stem. GENUS MORCHELLA The genus Morchella has the cap covered with a network of blunt ridges enclosing irregular depressed spaces. The spore-sacs are devel- oped in both ridges and depressions. All the species when young are of a buff yellow tinged with brown, but later they are darker. The stems are rather stout and hollow, white or whitish in some spe- cies, and attached to the cap at the apex only ; but in others, attached to the rim as well. All the species Es'-cti-lSn'-tS 141 M. esculenta Spore-sac Fungi — Ascomycetes are edible and highly esteemed. They must be looked for during wet weather, early in the season. They may be classed in two groups, according to the attachment of the stem.

They all have lobed, irregular, or saddle-shaped caps, which are fleshy, and attached to the stem at the apex. They are contorted in such a way that no two of the species appear alike. Helvella Helvella elastica (See Plate Facing Page 140) Ca/— Brownish grey. Cup-shaped, flattening out when mature ; when young, the under surface is covered with little spines or hairs. Both surfaces are smooth when mature. Stem — Slender, of the same colour as the cap, tapering toward the cap. Solid and white within.

They are living organisms which have no chlorophyll, or leaf-green, and which in their vegetative state resemble certain groups of the Protozoa, or unicellular animals, which live in water. In their manner of reproduction they show resemblances to certain fungi, and the spore cases or sporangia of some resemble tiny puffballs in form and maimer of ejecting their spores. In the growing stage they consist of a naked mass of yel- lowish or whitish protoplasm, which creeps about in the dark, in accumulations of dead parts of plants, or under the bark of rotting stumps or logs. When a spore germinates, the mem- brane about it bursts, and a bit of naked and slimy protoplasm escapes. This tiny mass creeps about, absorbing food from its surroundings, and increasing in size until it may perhaps cover an area of many inches. After a time spores begin to form, then either the whole mass is transformed into a single spore case or a number of spore cases are formed. The spore cases of Lycogala epidendron are pretty things, resembling pink coral beads. When fresh, a case is filled with a thin pink paste; but when mature, with fine brown dust-like spores. When the spore case bursts, these spores escape, and if they fall in favourable places the life cycle begins anew.

See Genus, p. 67 CHAPTER XIV : FU>JGI FOR THE HERBARIUM There are no plants more difficult to preserve for an her- barium than the fleshy fungi, and yet my personal observation leads me to believe that there are many people who would be willing to undertake the task if they knew how to set about it ; and there is no class of plants in which the assistance of the amateur may help the botanist more than in this, provided that, at the time of gathering a specimen, full descriptive notes are made of all the characteristics of the plant. To aid one in quickly taking notes, it is well to have with one in the field some printed or written blanks. A convenient form is suggested by the following outline, which is the one used by the Boston Mycological Club : Species Collected by No. Locality Date COLLECTOR'S NOTES. N.B. — When collecting, be sure to get the whole plant, base and all, uninjured; and to get young as well as mature specimens. Note here at once the Habitat.

Collector's Outfit. — For collecting fungi there is nothing better than a cheap sphnt basket with a cover. The size will .depend upon the ambition and strength of the collector. In ad- dition, a chisel for woody fungi and a trowel or broad-bladed knife will be found convenient ; also a few small boxes for fragile species, and a package of thin, tough, uncoloured paper in which other specimens may be put. Sheets of six inches square and also of twelve by twenty-four are convenient sizes. Before the specimens are put in the basket, those of a kind should be compactly piled in the centre of a sheet, and the four corners of the sheet brought together and fastened by twisting them. The slip with the notes may either be put inside the package or fastened on the outside. Care of Specimens. — As soon as possible after reaching home, the packages should be taken from the basket and spread out in convenient places. If the specimens are to be used imme- diately for identification, begin with the most perishable, or they will be lost by decay. If they are to be preserved for future use, put them in the warmest place available where they will not burn. This may be under or over the kitchen stove, or in the furnace-room of the hotel or laundry ; or, if any of these places is not practicable, then a drier may be improvised by placing over a lamp a frame made of wire screening. Collecting Spores. — At least one specimen of each kind should be set for spores. This is readily done by thrusting the stem of one plant through a hole in a disk of gummed paper so that the paper fits closely against the gills. This disk may be held in place by thrusting the stem of the fungus through a piece of thin paper and then bringing the paper above the cap and twisting the corners. Use white disks for fungi suspected of having coloured spores, and coloured paper for those suspected of 147 Fungi for the Herbarium having white spores. If there is any doubt, set two fungi — one with a coloured disit and the other with a white one. It is an easy matter to fix spores for future use, but a more difficult matter to fix them so fhat they represent a picture of the radiating gills. In order to do this the stem must be cut from the cap, and the cap must be so arranged over the paper that no draughts shall disturb the spores as they fall, and also so that it may be removed from the paper without disturbing the spores iifter they have fallen. The writer would suggest that two fine wires should be thrust horizontally and at right angles to each other through the cap, and that the ends of the wires should be supported in a convenient manner, so that the cap may just swing free from the paper which is to receive the spores. The whole must be covered to keep the spores from being disturbed by draughts. When the spores have fallen, the cover can be re- moved, the cap raised, and the spore-print fixed. Various methods of fixing spores for prints are recommended. The following are quoted from a bulletin of the Boston Mycoiog- ical Club : The following directions iox fixing spore prints are taken from Herpel (" Das Prapariren der Hutpilze "). Paper which is somewhat absorbent must be used; unglazed blue or black paper (of which the colour must be unaffected by the fixative) for white-spored species. The piece of paper bearing the spore print is to be laid, spores upward, in a flat plate or platter on which a thin layer of fixative has first been poured. The fixative is al- lowed to soak up through from below, and should not overflow the edges of the paper. When it is certain that the spores as well as the paper are thoroughly soaked, the preparation is removed and dried; sometimes, to prevent sticking, being laid on moistened blotting-paper. The fixative to be used will vary with the species. For instance, the spores of Cantharellus cibarius and some others may be fixed by water alone. The following solution is recommended for Boleti and species with coloured spores: One partsan- darac, two parts mastic, and two parts Canada balsam, dissolved in thirty parts of ninety-five per cent, alcohol. In the use of this it has been found that the time of soaking necessary to fix the spores is for Boleti,t\NO minutes; Dermini, Coprinarii, Gomphidius, Paxillus, Jiussula, and Lactarius, four to five minutes ; pink-spored agarics, also dark brown spored (as the meadow mushroom), and Cortinarii, six to eight minutes. It is important that the alcohol should be full strength. A gelatine solution is useful for white-spored species. This is prepared and used warm. Its strength varies with the species. Lepiota procera, Collybia radicata, and Clitocybe laccata may be fixed by a solution of one part gelatine to thirty of water. For species of Tricholoma this is too strong, and one to sixty, or one to two hun- dred must be the formula. The difficulty arises here from the fact that an excess of 148 Fungi for the Herbariun gelatine makes the spores transparent and even invisible. Their opacity may be secured by previous treatment with a solution of one part mastic in thirty of ether. For certain kinds {Tricholoma personatum, Lepiota granulosa, Amanitopsis vaginata, and others which experiment will discover), ten to twenty-five per cent, of alcohol must be added to the gelatine solution in order to make the spores adhere. Experience will doubtless show that other fixatives may be used. Gum arable, for instance, suggests itself This, however, if strong, is apt to cake the spores to- gether. If one method fails, invention and repeated trials must find a successful means. Reports are requested from all who engage in the amusement of making spore prints. To these a suggestion not without value is that dry agarics (like Marasmius and some Collyhias) may be kept in a condition to shed spores by putting moistened blotting-paper under them. Another method of making spore prints is to spray them from an atomizer with a solution of white shellac in alcohol. A saturated solution should be made, and then diluted fifty per cent, with alcohol. The Search for a Name. — When looking up a name for a plant, the best plan is to use fresh specimens, and, if a good supply can be had, make a careful comparison of all, so as to be sure that the characteristics are normal and not due to injury. If the attempt to find a satisfactory description is not successful, preserve the specimens dried, together with full notes, and send a part of them to the State botanist for determination. The name of a fungus is not the vital thing. In pursuit of a name do not neglect the plant. Observe it as it grows and in its different stages. Make a friend of it, and you will find it good company. The Preparation of Rough-dried Plants for the Herba- rium — Put the dried plants in a place where they will absorb just moisture enough to make them pliant. Either put them in a box containing something damp, as a wet sponge, sand, or paper; or spread them where they can absorb the moisture of the atmos- phere without getting too wet. When pliant, bend the stem and cap so that they lie in the same plane, and arrange them in as natural a form as possible; then place them between driers of un- glazed paper, with a weight just sufficient to keep them from curling out of shape. Mounting — The specimens may be placed loose in envelopes made by folding paper as for mosses or lichens, or they may be glued directly to mounting sheets, or they may be kept in boxes of varying sizes. 149 Fungi for the Herbarium Sections — A section of a fungus is a very thin slice cut from the plant by running a thin-bladed knife from the top of the cap down through the stem. When well made, sections of young and mature plants are valuable in addition to the notes and dried specimens. A section to be of any value must show the form of the cap ; the attachment of the gills to the stem ; the thickness of the stem ; and the interior, whether solid, hollow, or stuffed. To preserve the section, it must be placed, while fresh, upon a sheet of gummed paper, and then covered with a sheet of waxed paper, and placed between driers, under heavy pressure. Poisoning Herbarium Specimens — It will be found necessary to use every means possible to keep insects from the herbarium, as fungi are particularly subject to such pests. In order that no eggs and larvae may be packed away with the dried plants, it will be well to apply a poisonous solution to the specimens just after they have been moistened to be put into press. Professor Peck, the State botanist of New York, uses a solution made by dissolving strychnine in warm water, and then adding alcohol in sufficient quantities to make the mixture spread easily with a brush. Sulphate of strychnia }i ounce Warm water 4 or 5 ounces Alcohol About 2 ounces In addition to this precaution, the specimens must be kept where insects cannot get at them, or the havoc which they make will be disastrous. An ingenious person can improvise all the apparatus necessary for a successful collection of moderate size; and then, if his enthusiasm continues, he can provide himself with everything of the most improved style from dealers who make a specialty of botanical supplies. ISO CHAPTER XV : FUNGI FOR THE TABLE Before you attempt to use fungi for the table be sure that they are edible ; the consequences which follow a mistake are too serious to warrant any risks. Unless you are experienced in making careful observations and comparisons, eat only those fungi which have been shown to you by some one who has tried them and knows them to be wholesome. If you are experienced in making careful observations and comparisons, and wish to make experiments, make them cautiously, using a small quantity of the fungus for the first trial, and, if no ill effects are felt, in- crease the amount until you are satisfied as to its edibility. There is no general rule by which one may know an edible species from a poisonous species. One must learn to know each kind by its appearance, and the edibility of each kind by experi- ment. Some edible mushrooms change colour when bruised, some edible ones do not. Some poisonous mushrooms change colour when bruised, and some poisonous ones do not. Some mushrooms with bright colours, or viscid caps, or pleasant taste, or agreeable odour are edible, and some axe. poisonous. Some edible mushrooms will turn a silver spoon black, and so will some poisonous ones. Cautions for the Inexperienced Never use specimens which are decomposed in the slightest degree. Never use those which are at all burrowed by insects. Never collect, for food, mushrooms in the button stage, as it is difficult for a novice to distinguish the buttons of poisonous species from the buttons of harmless species. Never use fungi with swollen bases surrounded by sac-like or scaly envelopes. Fungi for the Table Never use fungi with milicy juice unless the juice is fed- dish. Never use fungi with caps thin in proportion to the width of the gills when the gills are nearly all of equal length, especially if the caps are bright coloured. Never use for food tube-bearing fungi in which the flesh changes colour when cut or broken, nor those with the tubes reddish. Be very cautious with all fleshy tube-bearing fungi. Never use for food fungi with a web-like ring around the upper part of the stem. The novice may safely experiment with Clavarias, coral fungi, morels, and puffballs. The Food Value of Fungi. — Many people thoughtful for the welfare of those with limited opportunities for varying their bill of fare have hoped to solve the problem by introducing into more general use the varied and abundant fungi which grow everywhere throughout our country. In order to accomplish this object, bulletins have been published by the several agricul- tural departments, and have been distributed freely to those wishing to have them. The result has been that a wide-spread interest has been created in this branch of botany, and fungi have become a common dish on tables where they were never before seen. As accessories, for relish or variety, edible fungi are undoubt- edly valuable ; but that they can never take the place of meat, as many fondly hoped, nor rank very high as an essential food, has been shown by the experiments of Mr. L. B. Mendel in the Sheffield Laboratory of Physiological Chemistry, Yale University. Mr. Mendel has demonstrated by chemical analysis and by ex- periments in artificial digestion that the proportion of proteid matter — the material which meat supplies — is smaller than it was formerly supposed to be, and also that a large proportion of that present is not acted upon by the digestive juices. Since, also, the proportion of water to solid matter is very great, being from seventy to ninety per cent, in the most desirable edible species, it would be necessary that a man should eat a great many pounds of even the richest fungi in order to obtain the daily requisite of proteid matter necessary to maintain a healthy constitution. The specimens marked edible in this book have been repeat- 152 Fungi for the Table edly tried by many people, and without ill effects. Some marked edible are harmless, but poor, while others are extremely de- licious and appetizing. A few directions for preparing different species for cooking are given below, that those who wish to experiment may have the benefit of the experience of others. Receipts for cooking the common mushroom, Agaricus campestris, may be found in all complete cook-books, and these receipts as they are given or modified may be used for other kinds also, provided that the directions for the preparation of the different species are fol- lowed. To Keep Mushrooms Temporarily. — Cleanse, remove the parts to be rejected, rinse in cold water the parts to be used, dry with a cloth, then put in boiling water and keep boiling for five or ten minutes. Drain, and wipe dry. To Prepare the Edible Agarics for Cooking. — Cleanse, cut off the stems and throw them away. Rinse the caps in cold water, drain, and leave in cold water acidulated with lemon or vinegar until just before using. To Toast Agarics. — Dry with a cloth, dust with flour, put a little butter, pepper, and salt on the gills. Lay the caps, gills upward, on a wire-net toaster, over a moderate fire, and cook from five to ten minutes. To Bake Agarics. — Dry with a cloth. Line a porcelain pie- dish with toast, spread the peeled caps on the toast, sprinkle with pepper and salt, and pour over them a few spoonfuls of thick cream. Cover with a plate, and place in a moderate oven for fifteen minutes. Serve hot. Or, Line the dish with toast dipped in hot water and buttered. Spread the caps on the toast, with half a teaspoonful of butter on each one. Cover, and cook in a warm oven for ten minutes. To Broil Agarics — Broil lightly on both sides over a bright fire. Arrange on buttered toast, sprinkle with pepper and salt. Put bits of butter or bits of toasted bacon on each, and set in the oven a moment. Serve hot. Mushrooms Stewed — Caps, peeled, one quart; butter, two tablespoonfuls; salt, one teaspoonful; pepper, one-third of ? teaspoonful; water or stock, one-half cupful. Boil gently in a covered stewpan for five minutes. Or, Caps, peeled and cut in pieces, one pint; butter, one table- 153 Fungi for the Table spoonful; salt, one-half teaspoonful; pepper, one pinch. Simmer in a stewpan for ten minutes. To Prepare Russulas — Reject the stems and gills, but not the peel. Cleanse the caps, rinse in cold water, then put for a moment in boiling water, and dry with a cloth. Cook by the receipts given for agarics. To Prepare Fungi with Milky Juice — Remove the stems, cleanse, rinse, and scald. Steep for six hours in a liquid pre- pared by mixing one wineglass of strong vinegar, one table- spoonful of salt, and one pint of water. Boil for ten minutes in salt and water. Cook by the receipts given for agarics. Lactarius deliciosus — Known by its greyish-orange cap marked with brighter zones, and by its orange milk. Also Lactarius volemus — Known by its reddish-brown cap, two to five inches across, with stems of the same colour, and white milk. May be prepared by simply removing the bases of the stems and then rinsing in water. To Prepare Amanitas — Reject the stems and peel, and cook but a short time. To Prepare Chanterelles — Cut off the base of the stems, rinse in cold water, soak in warm milk for six hours. Stew a long time with plenty of butter or stock. Use with meat hashes and stews, or in omelet. To Fry Chanterelles — Wash, slice, put in melted butter, and stir for ten minutes, simply keeping them warm. Add more butter, pepper, salt, crumbs of bread, and minced parsley, and fry over a hot fire. To Prepare Coprini — Ink Caps — Use only young specimens. Remove the base of the stems, wipe with a damp cloth. Throw for an instant into boiling water. Fry in boiling butter or lard. Remove from the pan as soon as they break or sink. Serve on toast. To Prepare Boleti — Remove the tubes with a spoon. Reject the stems. To Prepare Hydnum repandum — Remove the bases of the stems, and scrape off the spines. They require little cooking. To Prepare Morels— Cleanse; rinse by shaking them in several waters, or run the cold water from the faucet over them until the pits are thoroughly cleansed. They require to be cooked for a long time. 154 Fungi for the Table To Prepare Beefsteak Fungus — Gather when of a light- red colour. Remove the hard base, cleanse in cold water. For salad — Cut in thin slices and serve with dressed lettuce. Minced — Mince fine, put in a stewpan with butter, three ounces to the pound. Season with salt, pepper, minced parsley, and onion juice. Stew gently for twenty minutes. Bind with egg-yolk beaten in cream, and serve with toast. This mince may be used with veal or chicken hash. To Prepare Gyromitras. — Cleanse, cut in slices, boil in water fifteen minutes, then wash by shaking in two successive waters boiling hot. Dry on cloths, and cook as directed for morels. To Prepare Woody Pore-bearing Fungi — Polypor/E. — Take the soft parts of young specimens. Put in boiling water for a few moments, rinse in cold water, and dry on cloths. Spread with butter, lay in a stewpan, and cover; then keep them for ten minutes just warm enough to melt the butter. Strain, broil for fifteen minutes, or stew half an hour or more with gravy. To Prepare Clavarias and Branched Hydnums. — Cleanse, throw into scalding water for a moment, and then put into cold water made acid with lemon or vinegar until they are to be cooked. Divide the large ones, and tie the small ones into bundles. Place in a stewpan with bits of butter laid on them. Cover the pan, and expose to heat enough to- melt the butter. Leave for ten minutes, and drain. To Cook Clavarias. — Put into a hot stewpan with bits of butter; season with salt, pepper, and lemon juice. Cover closely, and stew for half an hour. Thicken with cream and flour, season to taste, and cook until tender. Clavarias may also be cooked as directed for agarics. To Prepare Puffballs. — Cleanse, peel, trim off the base. Cut in two pieces, and reject all those which are not pure white within. To Cook Puffballs. — Fry in lard five or six minutes, with bacon, parsley, onion juice, salt, and pepper; or cook as directed for agarics. To Cook the Giant Puffball. — Cut in slices half an inch thick, dip in the beaten yolk of egg, pepper, and salt. Fry in boiling fat for five or six minutes. Puffball Salad. — Cut in strips, and serve with green salad dressed with mustard, oil, and vinegar. 155 AUTHORITIES CONSULTED ATKINSON. Studies and Illustrations of Mushrooms, 1, II. Bull.
