umbonate. =Veil= absent or appearing only as fibrils or down on the
margin of the pileus. =Gills= sinuate (the small sudden curve near the
stem always apparent in the young plant), sometimes with a slightly
decurrent tooth. =Stem= central, usually stout, fleshy-fibrous, without
a bark-like skin. =Flesh= continuous with that of the pileus. =Ring= and
=Volva= absent. =Spores= white or dingy.
But one is known to be poisonous. Some are acrid or unpleasant in
flavor. With one exception all grow on the ground in pastures and woods,
appearing from May to late in the autumn.
Gills generally white or dingy, frequently spotted or stained. The
pileus may be smooth or adorned with fibrous or downy scales, dry,
moist, viscid or water-soaked.
The distinguishing feature of Tricholoma is the sinuate gills. In
Collybia the stem bears a distinct bark-like skin; in Clitocybe the
gills are never sinuate; species of Pleurotus are distinguished by
growing on wood only, and Paxillus by their strongly-incurved margin and
anastomosing gills.
In cooking Tricholoma consistency must be the guide to plan and time.
The tougher varieties require to be cut into small pieces and to be well
cooked, while the brittle and delicate varieties will cook quickly. Many
of them make excellent soups.
ANALYSIS OF TRIBES.
_A._ PILEUS VISCID, FIBRILLOSE, SCALY OR DOWNY, NOT WATER-SOAKED.
Stem fibrillose from the remains of the adnate universal veil.
LIMACINA (_limas_, a slug or snail, slimy). Page 61.
Cuticle of pileus viscid when moist, innately fibrillose or scaly, but
not lacerated; flesh of pileus thick, firm; margin almost naked.
* Gills not discolored, nor becoming reddish.
** Gills discolored, usually spotted with reddish-brown.
GENUINA. Page 67.
Cuticle of the pileus never moist or viscid; torn into downy or floccose
scales. Flesh soft, not water-soaked; margin involute and slightly downy
at first.
* Gills not changing color, nor spotted with red or black.
** Gills becoming reddish or gray, the edge at last generally with
reddish or black spots.
RIGIDA (_rigeo_, to be stiff). Page 74.
Pileus rigid, hard, somewhat cartilaginous when fleshy, very fragile
when thin, cuticle rigid, granulated or broken up when dry into smooth
scales, not torn into fibrils. Young specimens occur which are
fibrillose from the veil, not from laceration of the cuticle.
* Gills white or pallid, not becoming spotted with red or gray.
** Gills becoming reddish, grayish or spotted.
SERICELLA (_sericeus_, silky). Page 74.
Pileus first slightly silky, soon becoming smooth, very dry, neither
moist, viscid, water-soaked, nor distinctly scaly; rather thin, opaque,
absorbing moisture, but is the same color as the gills. Stem fibrous, by
which the smaller species resembling Collybia may be distinguished.
* Gills broad, rather thick, somewhat distant.
**:sericella2 Gills narrow, thin, crowded.
B. PILEUS EVEN, SMOOTH, NOT DOWNY NOR SCALY, NOT VISCID.
In rainy weather moist; when very young pruinose (but rarely
conspicuously) from the universal veil. Flesh soft and spongy or very
thin when it is water-soaked.
GUTTATA (_gutta_, a drop). Page 76.
Pileus fleshy, soft, fragile, marked with drop-like spots or rivulose.
Appearing in spring, rarely in autumn.
Cespitose, in troops or often in rings.
* Gills whitish.
** Gills becoming reddish or smoky-gray.

Pileus thin, somewhat umbonate; flesh at length soft, watery. Stem
rootless, containing a pith, entirely fibrous.
Flesh not exceeding in depth the width of the not broad, thin gills;
thinnest toward the margin, hence somewhat umbonate. Color of the pileus
either moist or dry, very variable in the same species. Pileus sometimes
pulverulent from the persistence of the veil in dry weather.
* Gills whitish, not spotted.
** Gills more or less violet, gray or smoky. Not represented.
_Series A._
PILEUS VISCID OR FIBRILLOSE, DOWNY OR SCALY.
I.—LIMA´CINA. Viscous when moist.
* _Gills not becoming discolored, nor becoming reddish._
=T. eques´tre= Linn.—_equestre_, belonging to a horseman or knight, from
distinguished appearance. =Pileus= fleshy, compact, convex becoming
expanded, obtuse, pale-yellowish, more or less reddish tinged, the disk
and central scales often darker, the margin naked, often wavy. =Flesh=
white or tinged with yellow. =Gills= rounded behind, close, nearly free,
_sulphur-yellow_. =Stem= stout, solid, pale-yellow or white, white
within. =Spores= 6.5–8×4–5µ.
=Pileus= 3–5 in. broad. =Stem= 1–2 in. long, 6–10 lines thick.
Pine woods, especially in sandy soil. Albany county. September to
November.
This is a noble species but not plentiful in our state (N.Y.). The
pileus is said to become greenish very late in the season. The stem, in
the typical form, is described as sulphur-yellow in color, but with us
it is more often white. The scales of the disk are sometimes wanting. In
our plant the taste is slightly farinaceous at first, but it is soon
unpleasant.
Var. _pinastreti_ A. and S. is a slender form having a thin, even
pileus, thinner and more narrow gills and a more slender stem. A.
crassus Scop., A. aureus Schaeff., and A. flavovirens Pers. are recorded
as synonyms of this species. _Peck_, 44th Rep. N.Y. State Bot.
Professor Peck later says in “Mushrooms and Their Use,” p. 52: “I
confidently add it to the list of edible species.”
New Jersey, Pennsylvania and West Virginia. In pine forests and groves.
September to frost. _McIlvaine._
I have eaten it since 1883. All disagreeable odor about T. equestre
(which I have seldom noticed) disappears upon cooking. The substance is
rather tough, but good.
=T. coryphæ´um= Fr.—chief, leader. From its distinguished appearance.
=Pileus= very fleshy but not compact, convex then plane, obtuse, viscid,
yellowish, streaked with small brownish scales. =Stem= solid, attenuated
upward. =Gills= emarginate, crowded, white, edge yellow.
Large and of striking appearance. In shady beech woods.
Pronounced a good edible by the Boston Myc. Club.
The color of the plants is given as greenish-yellow. Bull. Boston Myc.
Club, 1896.
=T. ustale= Fr.—_uro_, to burn. =Pileus= fleshy, convex, then plane,
obtuse, even, smooth, viscid, bay-brownish. =Stem= stuffed, equal, dry,
rufo-fibrillose, apex naked, silky, nearly smooth. =Gills= emarginate,
crowded, white, at length with reddish spots. _Cooke._
Chiefly in pine woods.
=Pileus= 3 in. =Stem= 2–3 in. long, about ½ in. thick.
=Spores= 5×8µ _W.G.S._; 7–8×5µ _Massee_.

=T. resplen´dens= Fr.—shining brightly. =Pileus= fleshy, convex then
nearly plane, even, bare, _viscid, white_, sometimes hyaline-spotted or
yellowish on the disk, shining when dry, the _margin straight_. =Flesh=
white, taste mild, odor pleasant. =Gills= nearly free when young, then
emarginate, somewhat crowded, rather thick, entire, white. =Stem=

It is of excellent flavor, consistency and food value.
=T. transmu´tans= Pk.—changing. =Pileus= convex, _nearly bare_, viscid
when moist, brownish, reddish-brown or tawny-red, usually paler on the
margin. =Flesh= white, taste and odor farinaceous. =Gills= narrow,
close, sometimes branched, whitish or pale yellowish, becoming dingy or
reddish-spotted when old. =Stem= equal or slightly tapering upward,
_bare_ or slightly silky-fibrillose, stuffed or hollow, whitish, often
marked with reddish stains or becoming reddish-brown toward the base,
white within. =Spores= subglobose, 5µ.
=Pileus= 2–4 in. broad. =Stem= 3–4 in. long, 3–6 lines thick.
Woods. The plants are often cespitose.
I suspect that Agaricus frumentaceus of Curtis’s catalogue belongs to
this species. Both the pileus and stem, as well as the gills, are apt to
assume darker hues with age or in drying, and this character suggested
the specific name. The species is classed as edible. _Peck_, 44th Rep.
N.Y. State Bot.
Curtis catalogues T. frumentaceum as edible.
T. transmutans is reported from many states. It has a mealy taste and
odor. Wherever it is found it is a valuable food species.
=T. sejunc´tum= Sow.—separated; from the peculiar manner in which the
gills separate from the stem. =Pileus= fleshy, convex then expanded,
umbonate, slightly viscid, _streaked with innate brown or blackish
fibrils_, whitish or yellowish, sometimes greenish-yellow. =Flesh=
white, fragile. =Gills= _broad, subdistant_, rounded behind or
emarginate, white. =Stem= solid, stout, often irregular, white. =Spores=
subglobose, 6.5µ.
=Pileus= 1–3 in. broad. =Stem= 1–3 in. long, 4–8 lines thick.
Mixed woods. Suffolk county, N.Y. September.
The plants referred to this species are not uncommon on Long Island,
growing on sandy soil in woods of oak and pine. They are usually more or
less irregular and the pileus becomes fragile. It is quite variable in
color, sometimes approaching a smoky-brown hue, again being nearly
white. The taste of the typical form is said to be bitter, but the
flavor of our plant is scarcely bitter. In other respects, however, it
agrees well with the description of the species. _Peck_, 44th Rep. N.Y.
State Bot.
=Spores= 6µ. _W.G.S._
Flesh is tender. Cooked, of good body and peculiar but pleasant flavor.
A valuable species, baked, scalloped, fried.
=T. terri´ferum= Pk.—_terra_, earth; _fero_, to bear. =Pileus= broadly
convex or nearly plane, irregular, often wavy on the margin, glabrous,
viscid, _pale-yellow_, generally soiled with adhering particles of earth
carried up in its growth. =Flesh= white, with no decided odor. =Gills=
thin, crowded, slightly adnexed, white, not spotted or changeable.
=Stem= equal, short, solid, white, _floccose-squamulose at the apex_.
=Spores= minute, subglobose, 3µ.
=Pileus= 3–4 in. broad. =Stem= 1–1.5 in. long, 6–8 lines thick.

Found in West Virginia, Pennsylvania, New Jersey. August to frost.
_McIlvaine._
Not inviting, hard to clean, nevertheless edible and good.
=T. portento´sum= Fr.—_portentosus_, strange, monstrous. =Pileus= 3–5
in. broad, _sooty_, livid, sometimes violaceous, fleshy, but thin in
comparison with the stoutness of the stem, convexo-plane, somewhat
umbonate, unequal and turned up, viscid, _streaked with black lines_
(innate fibrils), but otherwise even and smooth, the very thin margin
naked. =Flesh= not compact, white, fragile. =Stem= commonly 3 in. often
4–6 in. long, 1 in. thick, stout, _solid_, the whole remarkably
fibrous-fleshy, somewhat equal, _naked_, but _fibrilloso-striate_,
white; the base, which is occasionally attenuato-rooted, villous.
=Gills= rounded, almost free, 3–4 lines to as much as 1 in. broad,
_distant, white_, but varying, becoming pale-gray or yellow. _Fries._
=Spores= 4–5×4µ _K._; 5×4µ _W.G.S_
West Virginia, 1882; New Jersey, Pennsylvania, in woods and open places.
May to November. _McIlvaine._
It is one of the first toadstools I experimented upon. I have been
constant to it. Its caps fried in butter are unsurpassed.
** _Gills discolored, usually spotted with reddish-brown._
=T. fla´vo-brun´neum= Fr.—_flavus_, yellow; _brunneus_, brown. =Pileus=
fleshy, conical, then convex, at length expanded, subumbonate, viscid,
_clothed with streak-like scales_. =Stem= _hollow, somewhat ventricose_,
fibrillose, _at first viscid, yellowish within_, tip naked. =Gills=
emarginate, _decurrent_, crowded, yellowish, then reddish. _Fries._
Odor that of new meal. =Stem= 3–5 in. long, ½ in. thick, dull-reddish or
brownish. =Pileus= 3–6 in. broad, disk darker, dingy dull-red or
reddish-brown.
North Carolina, _Curtis_; damp woods, A. fulvus, _Schweinitz_.
Edible, _Cooke_, 1891.
=T. rus´sula= Schaeff.—reddish. (Plate XVIII, fig. 3, p. 60.) =Pileus=
fleshy, convex, becoming plane or centrally depressed, obtuse, viscid,
even or dotted with granular squamules on the disk, _red or incarnate_,
the margin usually paler, involute and minutely downy in the young
plant. =Flesh= white, sometimes tinged with red, taste mild. =Gills=
sub-distant, rounded behind or subdecurrent, white, often becoming
red-spotted with age. =Stem= solid, firm, whitish or rose-red,
squamulose at the apex. =Spores= elliptical, 7×4µ.
=Pileus= 3–5 in. broad. =Stem= 1–2 in. long, 6–8 lines thick.
Mixed woods. Albany. Cattaraugus and Steuben counties. September and
October.
According to the description the typical plant has the pileus incarnate
and the stem rosy-red, but in the American plant the pileus is generally
more clearly red and the stem white, though this is often varied by
reddish stains. _Peck_, 44th Rep. N.Y. State Bot.
Mixed woods. August until after frost. At Mt. Gretna, Pa. 1897–1898 the
patches were large, generous yielders.
Edible, _Cooke_; edible, _Cordier_, _Roques_.
T. russula is a dressy fungus and has a fashion of its own. The
mottlings upon its cap, gill and stem, in shades of red, subdued though
they be, give it a handsome personality distinct from any other.
The species is a variable one in its minor markings. When moisture is
prevalent the caps of all are viscid. Both young and old are often
cracked. Stems frequently not squamulose at apex, frequently rosy when
young, often flattened. The fibrous interior of the stem and its fibrous
connection with the flesh of the cap are very marked. Gills emarginate
in youth as well as in age. It is solitary, gregarious, occasionally
bunched.
An excellent fungus, a free late grower, meaty, easily cooked, and of
fine flavor.
=T. frumenta´ceum= Bull.—_frumentum_, made of corn. =Pileus= 2–3 in.
broad, whitish or clay-color and variegated dull red, truly fleshy,
convex then plane, obtuse, viscous, dry in fine weather, _even, smooth_.
=Flesh= white. =Stem= 3 in. long, ½ in. thick, _solid, equal,
fibrillose_ when dry, whitish. =Gills= _rounded_, somewhat crowded,
rather broad, white, at length spotted-red.
Wholly _becoming pale white_, but the stem and pileus are alike
_marked-red_, and the gills are at length reddish, wherefore, as well as
for the _strong smell of new meal_, it is undoubtedly nearest to A.
pessundatus. When full grown it has all the appearance of Entoloma. On
the ground. _Stevenson._
=Spores= 6µ _W.G.S._
North Carolina, _Curtis_. Edible. Porcher says Dr. Curtis was the first
to declare it edible.
=T. pessunda´tum= Fr.—_pessum dare_, bent downward. =Pileus= fleshy,
compact, convex, very obtuse, repand, viscid, _granulose or spotted_.
=Stem= solid, firm, at first ovato-bulbous, _everywhere villose with
whitish scales_. =Gills= emarginate, nearly free, crowded, white, at
length spotted with red.
In pine woods. Odor and taste mealy.
=Pileus= bay, reddish, paler at the margin. Stature of Ag. equestris.

=T. decoro´sum= Pk.—_decorus_, decorous. =Pileus= firm, at first
hemispherical, then convex or nearly plane, adorned with numerous
_brownish sub-squarrose tomentose scales_, dull ochraceous or tawny.
=Flesh= white. =Gills= close, rounded and slightly emarginate behind,
the edge slightly scalloped. =Stem= solid, equal or slightly tapering
upward, white and smooth at the top, elsewhere _tomentose-scaly_ and
colored like the pileus. =Spores= broadly elliptical, 5×4µ.
=Pileus= 1–2 in. broad. =Stem= 2–4 in. long, 2–4 lines thick.
Decaying trunks of trees. Catskill mountains and Alleghany county.
September and October.
A rare but beautiful species. It is often cespitose. It departs from the
character of the genus in growing on decaying wood. _Peck_, 44th Rep.
N.Y. State Bot.
Tricholoma decorosum is not rare in Pennsylvania. I have found it at
Angora, Philadelphia and in Chester county, Pa., growing in clusters and
singly. At first sight one might take it for one of the many forms of
Armillaria, but even cursory examination shows the difference.
It is of good consistency and flavor, having a decided mushroom taste.
=T. flaves´cens= Pk.—pale yellow. =Pileus= convex, firm, often
irregular, dry, _slightly silky becoming bare_, sometimes cracking into
minute scales on the disk, _whitish or pale yellow_. =Flesh= whitish or
yellowish. =Gills= close, white or pale-yellow, emarginate, floccose on
the edge. =Stems= firm, solid, often unequal, central or sometimes
eccentric, single or cespitose, colored like the pileus. =Spores=
subglobose, 5µ in diameter.
=Pileus= 2–3 in. broad. =Stem= 1–2.5 in. long, 4–6 lines thick.
Pine stumps. Albany and Rensselaer counties. October.
The species seems to be related to T. rutilans but has not the red or
purplish tomentum of that fungus. It, like T. decorosum, is always
lignicolous. T. rutilans is sometimes so. _Peck_, 44th Rep. N.Y. State
Bot.
Frequently found in New Jersey, Pennsylvania and West Virginia. Pine
stumps. September to frost. _McIlvaine._
The flesh compares with that of T. rutilans, and makes an equally good
dish.
=T. gran´de= Pk. =Pileus= thick, firm, hemispherical, becoming convex,
often irregular, dry, _scaly_, somewhat silky-fibrillose toward the
margin, _white_, the margin at first involute. =Flesh= grayish-white,
taste _farinaceous_. =Gills= close, rounded behind, adnexed, white.
=Stem= stout, solid, fibrillose, at first tapering upward, then equal or
but slightly thickened at the base, pure white. =Spores= elliptical,
9–11×6µ.
=Pileus= 4–5 in. broad. =Stem= 2–4 in. long, 1–1.5 in. thick.
Among fallen leaves in woods. Cattaraugus county. September.
The plants are often cespitose, and then the pileus is more or less
irregular and the gills somewhat lacerated. The species is related to T.
columbetta, from which its larger size, constantly scaly pileus, more
cespitose mode of growth, larger spores and farinaceous taste separate
it. The scales of the pileus are brownish, and the pileus itself is
sometimes slightly dingy on the disk. The young margin is pure white
like the stem, and both it and the upper part of the stem are sometimes
studded with drops of moisture.
The plant was found on trial to be edible, but not of first quality. The
flesh is not very tender, nor the flavor captivating even in young
specimens. _Peck_, 44th Rep. N.Y. State Bot.
Mt. Gretna, Pa. Mixed woods. August to frost. _McIlvaine._
Gross when old. Young specimens of medium quality and flavor.
=T. columbet´ta= Fr.—_columba_, a pigeon. (Plate XVIII, fig. 5, p. 60.)
=Pileus= convex, then nearly plane, fleshy, obtuse, rigid, somewhat
flexuous, dry, _at first bare, then silky-fibrillose_, becoming even or
scaly, _white_, the margin at first _involute_, more or less tomentose.
=Flesh= white, taste _mild_. =Gills= close, emarginate, thin, white.
=Stem= stout, solid, unequal, nearly bare, white. =Spores= 7–8×4.5µ.
The species is very variable and the following varieties have been
described:
Var. _A_. =Pileus= nearly always repand or lobed, at first bare, even,
at length cracked-scaly, often reddish spotted, the margin when young
inflexed, tomentose. =Stem= obese, even, unequal, swollen, an inch
thick. The typical form.
Birch wood among mosses.
Var. _B_. =Pileus= subflexuous, silky-fibrillose, at length scaly,
sometimes dingy-brown spotted, the margin scarcely tomentose. =Stem=
longer, equal or slightly narrowed at the base.
Bushy places. Intermediate between _A_ and _C_.
Var. _C_. =Pileus= regular, flattened, evidently fibrillose, sometimes
spotted with blue, four inches broad. =Stem= equal, cylindrical,
fibrillose-striate, four inches long.
Beech woods. A showy variety so diverse from variety _A_ that it might
be regarded as a distinct species, did not variety _B_ connect them, and
so much resemble both that it might with equal propriety be referred to
either.
=Pileus= 2–4 in. broad. =Stem= 1–4 in. long, 3–12 lines thick.
Woods and pastures. Albany county, N.Y.
It may be distinguished from T. album by its mild taste. It is recorded
as edible. _Peck_, 44th Rep. N.Y. State Bot.
Edible, _Curtis_, _Cooke_, _Stevenson_.
This much varied Tricholoma is as varied in its habitat. I have found it
on vacant lots in Philadelphia, in mixed woods at Devon, Pa., and in the
forests of the West Virginia mountains, and eaten it since 1881.
It cooks readily and is of mild, agreeable flavor.
=T. ru´tilans= Schaeff.—_rutilo_, to be reddish. =Pileus= fleshy,
campanulate becoming plane, dry, at first _covered with a dark-red or
purplish tomentum_ then somewhat scaly, the margin thin, at first
involute. =Flesh= yellow. =Gills= crowded, rounded, _yellow, thickened
and downy on the edge_. =Stem= somewhat hollow, nearly equal or slightly
thickened or bulbous at the base, soft, pale-yellow variegated with red
or purplish floccose scales. =Spores= 6.5–8×6.5µ.
