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.

]

=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.

=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.

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.

=H. sublateri´tium= Schaeff.—_sub_ and _later_, a brick. (Plate XCVII,

fig. 3, p. 352.) =Pileus= 2–3 in. and more broad, tawny-brick-red, but

paler round the margin and covered over with a superficial, somewhat

silky, whitish cloudiness (arising from the veil), fleshy,

convexo-plane, obtuse, _discoid_, _dry_, even, _becoming smooth_.

=Flesh= _compact_, white, then becoming yellow. =Stem= 3–4 in. long, 3–5

lines thick, _stuffed, stout_ and firm, commonly manifestly attenuated

downward, rarely equal, _scaly-fibrillose_, fibrils pallid, rust-colored

downward. =Cortina= superior, at first _white, at length becoming

black_. =Gills= adnate, more or less crowded according to stature,

narrow, at first _dingy yellowish_ and darker at the base, _then sooty_,

and at length inclining to olivaceous.

=Spores= brownish purple. Somewhat cespitose. =Stem= incurved from

position. There are many varieties: _B_, somewhat solitary, the pileus

and stem, which is thickened at the base, of the same color, reddish.

_C_, smaller, pileus light yellowish, the hollow stem equal. _Schaeff._

Var. _squamo´sum_, Cooke. Pileus convex, bright brick-red, shading to

yellow at the margin, spotted with superficial scales. Flesh very thick,

yellowish. Gills narrowish, adnate. Stem elongated, stout, pale above,

rust-colored below, hollow, veil hanging from the margin when young.

On trunks. A very beautiful variety, larger and more robust than the

typical form. _Massee._

=Spores= 6×3µ. _W.G.S._; elliptical, sooty-brown, 8×4µ _Massee_.

West Virginia, 1881–1885; Pennsylvania, New Jersey, densely cespitose on

stumps and roots. October to long after frosts. _McIlvaine._

Edible. _Dr. Taylor_, 1893. Dept. of Agr. Rep. No. 5.

H. sublateritium has many forms. Both Fries and Stevenson indicate this

as a variable species and my own observation confirms the truth of this.

This is a very common autumnal species, lasting into the winter. Old

authors give it as bitter and very poisonous. I tested it in 1881 and

have been eating it, in common with all Hypholomas I have found, ever

since. At times it is bitter. I believe this to be due to the passage of

larvæ through the flesh. Unattacked specimens are slightly saponaceous

to the taste while others in the same bunch are bitter.
