Part 34

This species is remarkable for the peculiar upper surface of the pileus which is broken into pyramidal areas. The sides of these are marked by parallel lines in such a way that they appear as if formed by small tablets placed one upon another, each successive tablet being a little smaller than the one immediately preceding it. Only dried and broken specimens have been seen by me and the notes of the collector do not give the color of the young lamellæ. There is a trace of a thick ring on the broken stem of one specimen. _Peck_, Bull. Torr. Bot. Club, Vol. 25, No. 6, 1898.

Not elsewhere reported. Edible qualities not given.

=PILOSACE= Fr.

(Plate XCV.)

Hymenium differentiated from the stem. =Gills= free from the stem; general and partial veil both absent, hence there is no ring on the central stem. =Spores= purple-brown.

A peculiar genus, with the habit of Agaricus, but without a trace of a ring. _Massee._

P. eximius Pk., 24th Rep. N.Y. State Bot., is the only species thus far reported in America. Edible qualities unknown.

STROPHA´RIA.

_Gr_—a sword-belt. (Referring to the ring.)

=Flesh= of stem and pileus _continuous_. =Veil= present, when ruptured forming a distinct ring on the stem. =Gills= more or less _adnate_.

On the ground or epiphytal.

Separated from all the genera of the purple-spored series but Agaricus by the presence of a distinct ring, and from that by the continuity of flesh in stem and pileus, and by the gills not being free. =Pileus= somewhat fleshy, sometimes viscid.

The species belonging to this genus are rather small, and from their habitats are frequently passed or overlooked. Yet many of them are common and plentiful. Those which have been tested are excellent and worth seeking in their season. The entire genus has been under a cloud. Writers upon it assert some of its members to be dangerously poisonous. So far as carefully tested by the writer no doubtful one has been encountered, and one—semiglobata—has been eaten by himself and friends since 1881, notwithstanding its dangerous reputation.

The division between this genus and Agaricus is not always sharply defined. S. æruginosa, S. semiglobata and S. stercoraria were formerly placed in Psalliota, now Agaricus.

ANALYSIS OF TRIBES.

_A._ VISCIPELLES (_viscum_, bird-lime; _pellis_, a skin). Page 349.

Pellicle of the pileus even or scaly, generally viscid.

* Mundi—_mundus_, clean. Not growing on dung.

** Merdarii—_merda_, dung. Ring often incomplete.

_B._ SPINTRIGERI (Stropharia spintriger).

Pileus without a pellicle, but fibrillose, not viscid. None known to be edible.

_A._ VISCIPELLES. Pellicle of the pileus even or scaly.

* Mun´di—_not growing on dung._

(Plate XCVI.)

=S. ærugino´sa= Curt.—_ærugo_, verdigris. =Pileus= fleshy, but not compact, convex-bell-shaped then flattened, somewhat umbonate (obtuse when larger), _with very viscid pellicle_, the ground color yellowish but _verdigris from the azure-blue slime_ with which it is more or less covered over, becoming pale as the slime separates. =Stem= _hollow_, soft, equal, _at the first scaly_ or fibrillose _below the ring, viscid, becoming_ more or less _azure-blue green_. =Ring= distant. =Gills= adnate, plane, 2 lines and more broad, not crowded, soft, whitish then dusky, becoming somewhat purple.

The above are the essential marks of this species. Variable in form, sometimes cespitose. The typical and handsomest form is gathered in soaking weather in later autumn in shaded woods; it is large (pileus and stem 3 in. and more), stem squarrose with white spreading scales, intensely verdigris or azure-blue-pelliculose and very glutinous. From this there is a long series of forms with the gluten more separating (on the separation of the gluten the pileus becomes yellow), and the scales alike of the pileus and stem rubbed off. Finally, a smaller form occurs in open meadows, stem scarcely 2 in. long, only 2 lines thick, becoming azure-blue-green and without scales, pileus 1–2 in. broad, pale verdigris soon light yellowish, less viscid. In this form the ring is incomplete, while in the typical form it is entire, spreading, and persistent.

In woods, meadows, etc. Common. July to November. _Stevenson._

=Spores= ellipsoid or spheroid-ellipsoid, 8×4–5µ _K._; 5×7µ _W.G.S._; elliptical, 10×5µ _Massee_.

POISONOUS. _Stevenson._

“There is a white variety, in which the pileus is perfectly white from the first.” _Cooke._

S. æruginosa has been noted here by Schweinitz in Pennsylvania, Curtis in North and South Carolina, Frost in Vermont and Massachusetts, Harkness and Moore, California, Morgan, Ohio. The qualities of the American representatives are not reported. I have not seen the species. As it is asserted to be poisonous by European writers it may be. M.C. Cooke says: “It has the reputation, which is somewhat general on the continent, of being poisonous, but probably this is only assumed from its disagreeable taste and repulsive appearance.” Collectors are cautioned to look out for it, and not to eat of it carelessly.

I can find no case of poisoning by this species reported. It presents another case of “Not proven.”

** Merda´rii—_ring often incomplete._

=S. stereora´ria= Fr.—_stercus_, dung. =Pileus= 1 in. broad, yellow, fleshy, but thin at the margin, hemispherical then expanded, obtuse, orbicular, with a viscid pellicle, naked, smooth, even or at length slightly striate only at the margin. =Stem= 3 in. and more long, 2–3 lines thick, stuffed with a separate fibrous pith, equal, clothed to the ring (which is scarcely 1 in. distant from the pileus, viscous, narrow, but somewhat spreading) with the flocculose veil which is at the same time viscous (so that it appears as if smooth), yellow. =Gills= adnate, very broad behind, 2 lines broad, somewhat crowded, dusky-umber or dusky-olivaceous, of one color, quite entire.

Stem silky-viscous when moist, when dry becoming even, shining and yellowish-white, and without a manifest veil. The gills are truncate and somewhat decurrent. _Fries._

=Spores= 17×13µ _W.G.S._; elliptical, 18–20×8–10µ _Massee_.

West Virginia, 1881–1885; Pennsylvania; New Jersey. June to November. _McIlvaine._

I have enjoyed this species, which is common, since 1881. It is usually conspicuous upon droppings and manure piles. It also occurs on richly-manured ground, in wood and field, usually single; sometimes two or three are united.

Caps and stems are edible, but do not cook in the same time. It is better to cook the caps only. They are delicious.

(Plate XCVI_a_.)

=S. semigloba´ta= Batsch.—_semi_, half; _globus_, a ball. =Pileus= commonly ½ in. broad, _light-yellow_, slightly fleshy, hemispherical, not expanded, very obtuse, even, _viscous_. =Stem= about 3 in. long, 1 line thick, tubed, slender, firm and straight, equal, even, smooth, becoming yellow, paler at the apex, powdered with the spores, otherwise smeared with the glutinous veil which is abrupt above terminating in an _incomplete_ (not membranaceous) viscous, distant _ring_. =Gills= adnate, _very broad_, plane, _clouded with black_.

=Spores= dusky-purple. _Stevenson._

=Spores= blackish-purple, 13×8µ _W.G.S._; elliptical, ends rather acute, 12×6µ _Massee_.

Grows on dung, rich lawns and pastures. April to November. A common, frequent, solitary species, easily recognized by its hemispherical cap, dark mottled gills. At first sight it resembles Naucoria semiorbicularis.

The caps are equal to any mushroom. I have eaten it since 1881. M.C. Cooke says: “It was Sowerby who drew attention to this species as dangerous, and intimated that it had been fatal. Since that period we are not aware of any further evidence against it.”

It is tender, good and harmless.

=Pileus= more or less fleshy, margin at first incurved. =Veil= _webby, adhering in fragments to the margin of the pileus_, not forming a distinct ring on the stem. =Stem= fleshy, similar in substance to that of the pileus with which it is continuous. =Gills= attached to the stem, sometimes with a notch at the juncture (emarginate), occasionally separating and then appearing to be free.

Generally cespitose, mostly growing on wood above or under the ground.

Members of this purple-spored genus grow upon decayed wood, either standing or as roots in the ground, or from ground heavily laden with woody material. They grow singly, in groups, or in densely-tufted or overlapping masses. The several species vary in shades of yellow, red, orange, brick-color and brown; their caps are from 1–6 in. across; their stems are short or long, as the number in the cluster permits; when growing singly the stems are short and sturdy. There is a floccose veil, or remnants of one, about the stem. The gills are yellowish, greenish, olivaceous or greenish shades of yellow, gray, purple, almost black. They are showy, easily recognized and are found from September until mid-winter. I have gathered them when frozen hard. The flesh is solid, or spongy, flexible or fragile, white or yellowish; the tastes are sweet, nutty, bitter and saponaceous. Patches of them—and they are frequent in almost every woods in the land—often yield several bushels. Tons of them annually go to waste.

Old authors and some copyists say “the species are not edible, the tough ones being bitter, the fragile ones almost void of flesh.” Eighteen years of experience with them warrants my saying that there is not a single wild genus approaching it in economic value, and when its most prominent species are properly cooked, few equal it in consistency and flavor. As a pickle the Hypholomas have no superior.

Half a dozen or more of the species are exceedingly difficult to separate. Professor Peck has happily made a new species, H. perplexum, which is well named. For all culinary purposes these affiliated species may be gathered under that convenient name; for botanic purposes his description covers several perplexing characteristics common to what have been written as separate species, and covers a composite species.

The occasional bitter taste of some species is not constant, and can not be relied upon as a distinguishing mark. In the same tufts some individuals may be mild, others bitter; some individuals in groups are in a position and of an age to absorb water; others are not. There will be a marked difference in their taste raw. A few in the same group may have been infested by insects; others not. Those infested are often intensely bitter, while their companions are of pleasant flavor. The same remarks apply to neighboring clusters and individuals. I am of the opinion, from long observation, that the bitter is largely due to the injury and excrement of larvæ. Changes of taste occur in toadstools in a most marked and rapid manner. Apples from the same tree, chestnuts from the same tree, acorns from the same oak, radishes from the same seed, blackberries from the same bush, differ widely in taste. Why not toadstools of the same species?

I have often seen species of this genus, described as having stems up to 5 in. long, stretch and twist their stems to over a foot in order to get their caps from the inside of, or from a crack in a decaying stump, out into the light; and I have seen stems of the same species stout, solid and sturdy when individuals grew upright and singly. But wherever and however they grow, Hypholomas are safe. I have eaten them indiscriminately since 1881, and as long ago as 1885 published their edibility.

FASCICULA´RES. Pileus smooth, etc.

=H. perplex´um= Pk.—_perplexus_, perplexed. Perplexing Hypholoma. (Plate XCVII, fig. 2, p. 352.) =Pileus= convex or nearly plane, glabrous, sometimes broadly and slightly umbonate, reddish or brownish-red fading to yellow on the margin, the flesh white or whitish. =Lamellæ= thin, close, slightly rounded at the inner extremity, at first pale-yellow, then tinged with green, finally purplish-brown. =Stem= nearly equal, firm, hollow, slightly fibrillose, whitish or yellowish above, rusty-reddish or reddish-brown below. =Spores= elliptical, purplish-brown, 8×4µ.

The Perplexing hypholoma has received the name because it is one of a group of five or six very closely allied species, whose separation from each other is somewhat difficult and perplexing. Of these six species three have a decidedly bitter, unpleasant flavor, and three are mild, or not decidedly bitter, if we may rely on the published descriptions of them. The three bitter ones, also, have no purplish tints to the mature gills; but two of the mild ones have. By using these and other distinguishing characters the six species may be tabulated and their several peculiarities more clearly shown.

Taste bitter 1

Taste mild, or not clearly bitter 3

1. Stem solid or stuffed, flesh whitish, gills sublateritium whitish, then sooty-olive

1. Stem hollow, flesh yellow 2

2. Cap yellow or tinged with tawny, stem yellow, fasciculare gills yellow, becoming greenish

2. Cap brick-red, stem ferruginous, gills green, elæodes becoming olive

3. Cap red or brick-red, with a yellow margin; gills perplexum yellow, then greenish, finally purplish-brown

3. Cap yellow, or slightly tawny on the disk only 4

4. Gills gray, becoming purplish-brown capnoides

4. Gills yellow, becoming gray, neither green nor epixanthum purplish

Probably in general appearance the Perplexing hypholoma most nearly resembles the brick-red Hypholoma, H. sublateritium; but it has often been mistaken for the tufted Hypholoma, H. fasciculare. From this it may be separated by the more red cap, the whitish flesh, the purplish-brown color of the mature gills, and the mild flavor. From H. sublateritium it is distinguished by its usually smaller size, more slender hollow stem, the yellow greenish and purplish tints of the gills, and the absence of a bitter flavor. Some may prefer to consider it a variety of this fungus, rather than a distinct species.

Its cap is 1–3 in. broad, its stem 2–3 in. long and 2–4 lines thick. It commonly grows in clusters, though sometimes singly, on or about old stumps or prostrate trunks of trees, in woods or open places. The caps of the lower ones in a cluster are often defiled and apparently discolored by the spores that have lodged on them from the upper ones. It appears in autumn, and continues until freezing weather stops its growth. It is a very common species, as well as a late one, and may often be gathered in large quantity. Its flavor is not first quality, but with good preparation it makes a very acceptable dish. It has been tested by myself and correspondents several times, and has been proved harmless. _Peck_, 49th Rep. N.Y. State Bot.

West Virginia, 1881–1885; New Jersey, North Carolina, Pennsylvania, October to January. On stumps, roots, ground containing decayed woody matter. _McIlvaine._

H. perplexum is abundant in most if not all the states. I have eaten it and its allied species since 1881; dried them, pickled them, and fed them to many. If the collector gets puzzled, as he will, over one or all of these species, because no description fits, he can whet his patience and appetite by calling it H. perplexum and graciously eating it.

=H. capnoi´des= Fr. _Gr_—like smoke, from the color of the gills. =Pileus= 1 in. sometimes 3 in. broad, _ochraceous-yellowish_, fleshy, convex, then flattened, obtuse, dry, _smooth_. =Flesh= somewhat thin, white. =Stem= 2–3 in. long, 2–4 lines thick, growing together at the base, _hollow_, equal, often curved and flexuous, _becoming silky-even_, pallid, whitish at the apex, here and there striate, becoming rust-colored under the surface-covering when old. Cortina appendiculate, white, then becoming brownish-purple. =Gills= adnate, easily separating, somewhat crowded, rather broad, arid, _at first bluish-gray then becoming brownish-purple_.

Cespitose, fasciculate; odor and taste mild. On pine-stumps. Uncommon. _Fries._

=Spores= ellipsoid-spheroid, 7×5µ _K._; elliptical, brownish-purple, 8×4µ _Massee_.

California, _H. and M._; Minnesota, not necessarily in fir-woods, _Johnson_; New York, on or about stumps or decaying wood of spruce. _Peck_, 50th Rep.

Haddonfield, N.J., 1894. Pine roots and stumps, and on ground. Cespitose. September to frost. _McIlvaine._

A pretty species with caps up to 1½ in. across. =Stem= 2–4 in. long, ¼-⅜ in. thick, growing together (connate). The taste and smell are pleasant. The basket is soon filled from its clusters. There is not a better Hypholoma. The slightly soapy taste which attaches to most of the abundant and better known species is absent in this.

=H. fascicula´ris= Huds.—_fasciculus_, a small bundle. (Plate XCVIII, p. 352.) =Pileus= about 2 in. broad, _light yellow_, the disk commonly darker, fleshy, thin, convex, then flattened, somewhat umbonate or obtuse, even, smooth, dry. =Flesh= _light yellow_. =Stem= very variable in length, hollow, thin, incurved or flexuous, fibrillose, of the same color as the pileus and flesh. =Gills= adnate, very crowded, linear, _somewhat deliquescent, sulphur-yellow then becoming green_.

It is very easily distinguished from the preceding species by its _bitter odor and taste, light-yellow flesh, and somewhat deliquescent, sulphur-yellow then green gills_. It forms also more crowded clusters. There are many remarkable varieties; one _robustior_ (more robust), stem thickened at the base, another _nana_ (dwarf), both on the ground.

Cespitose on old stumps and the ground. Extremely common. _Stevenson._

=Spores= elliptical, 7×4µ _Massee_; 6–7×4µ _K._; 6×4µ _W.G.S._; ferruginous purple, 6×4µ _Morgan_.

“It is very usual to regard this as a poisonous species, but possibly it is not so in reality.” _Cooke._

West Virginia, 1881, Pennsylvania, New Jersey, North Carolina, _McIlvaine_.

A very common species appearing in October and lasting until well into the winter, growing in large, overlapping masses or in tufts from old stumps or roots, and about trees where decay has begun. Sometimes solitary. It is then short-stemmed and sturdy. There are several closely allied species. To know the one from the other, a careful study of the group is necessary. (See introduction to genus, H. epixanthum, H. sublateritium, H. capnoides, H. elæodes, and H. perplexum.) Old authors give it as bitter and poisonous. The bitter is not always present. Any there is disappears in cooking. It is not poisonous, but one of our most valuable species. I have eaten it since 1881. A little lemon juice or sherry will cover the slightly saponaceous taste sometimes present. The caps only are good. It makes a choice pickle and a good catsup.

=H. epixan´thum= Fr. _Gr_—_epixanthos_, yellowish-brown. =Pileus= 2–3 in. broad, light-yellow or becoming pale, the disk commonly darker, fleshy, moderately thin, convexo-plane, obtuse or gibbous, even, _slightly silky then becoming smooth_. =Flesh= white, becoming light-yellow. =Stem= about 8 in. long, 3–4 lines thick, _hollow_, attenuated from the thickened base or equal; _floccose-fibrillose, pale rust color_ or becoming dingy-brown _below_, with a frosty bloom at the apex; veil hanging from margin of pileus, white. =Gills= adnate, crowded, _at first light yellow-white, at length becoming ash-colored_, not deliquescent, and not becoming purple or green.

Strong smelling, odor acid; extremely variable in stature; not hygrophanous. _Fries._

=Spores= elliptical, 7×4µ _Massee_.

West Virginia, Pennsylvania, New Jersey, North Carolina. On oak, chestnut stumps and growing from tree roots in ground. October to December. _McIlvaine._

(See H. perplexum, H. sublateritium and compare descriptions.)

This species, in common with its allies, is extremely hard to determine. When growing singly from roots or from ground heavily charged with decaying wood, it is a sturdy, solid plant; when in clusters the stem is longer, more flexible and the whole character of the plant is modified. Except for botanic purposes there is no occasion to puzzle over it. It is in every way an excellent and useful fungus.

=H. disper´sus= Fr.—_dispergo_, to scatter. =Pileus= 1–1½ in. broad, _tawny-honey-color_, not hygrophanous, _slightly fleshy_, bell-shaped then convex, at length expanded, even, _superficially silky round the margin_ with the veil, or squamulose, otherwise even and smooth. =Flesh= thin, a little paler than the pileus. =Stem= 2 in. or a little more long, 2 lines thick, tubed, equal, _tense and straight_, tough, _fibrilloso-silky_, somewhat rust-colored, becoming dingy-brown at the base, pale at the apex. =Gills= adnate, thin, _ventricose, broad_, 3–4 lines, _crowded, at first pallid-straw color, at length crowded_, obsoletely green. _Fries._

Gills broader than H. fascicularis, etc. Solitary, scarcely ever cespitose. On pine stumps and the ground. April to November.

=Spores= elliptical, 7×3–4µ _Massee_.

North Carolina, in pine woods, _Curtis_; California, _H. and M._; West Virginia, Pennsylvania, North Carolina, New Jersey, _McIlvaine_.

Difficult to distinguish from H. fascicularis when growing solitary. Its edible qualities are precisely the same.

=H. elæo´des= Fr. _Gr_—_an olive_; _Gr_—_eidos_, appearance. =Pileus= brick-red or tan, fleshy, rather plane, somewhat umbonate, _dry, smooth_, opaque. =Flesh= yellow. =Stem= stuffed then hollow, equal, commonly slender, incurved or flexuous, fibrillose, of the same color as the pileus, becoming rust-color. =Gills= adnate, crowded, thin, _green then_ pure olivaceous.

Cespitose. Odor bitter. On trunks and on the ground. _Fries._

=Cap= 1–2 in. across. =Stem= 2–4 in. long, ¼-⅜ in. thick, stuffed then hollow.

West Virginia, 1881–1885, Haddonfield, N.J.; Pennsylvania. On stumps, roots and ground in woods, etc. _McIlvaine._ Not reported elsewhere.

Its habit is the same as H. fascicularis, to which it is closely allied, and to me seems but a form of this very variable species. It is equally good.
