TRICHOLOMA
glabrous, sometimes striate, spores elliptical, minutely rough, pale dirty flesh
color, 7-8 X 4-5 m-
Singly, in groups, or in clusters of several, on the ground, often under old
leaves, in the woods or on decaying vegetable matter. Sept. -Oct.
This species is rather common and is one of the better edible species,
although it may have a disagreeable flavor if the pilei are old and water-soaked.
It varies considerably in color but there is always some lilac.
According to European accounts, T. personatum exhibits the blue color
only in the stipe, and specimens with blue pilei and lamellae are referred to
T. nudum (Bull, ex Fr.) Kummer. We have referred a smaller species with
much deeper color and slightly diff'erently colored spore print to T. nudum.
The exact identity of these species is somewhat in doubt but they are all edible.
This group of species in which the spore print is not pure white and at least
some of the spores are minutely roughened has been separated from Tricholoma
as the genus Lepista.

piLEUS 2-4 in. broad, at first convex becoming expanded, reddish bay to
reddish brown or rufous tan, paler toward the margin to a whitish flesh color,
viscid, glabrous, margin inrolled at first, flesh white, tinged reddish, firm,
odor and taste farinaceous, lamellae sinuate to adnate or decurrent by a
tooth, crowded, white staining reddish, stipe 1 }4-3 in. long, y^-\ in. thick,
equal to shghtly bulbous and narrowed below the bulb, glabrous or with a few
fibrils, whitish or becoming stained reddish brown, solid, spores white, ovoid-
ellipsoid, 4.5-6 X 2.5-4 M.
Gregarious, in troops under conifers. Sept.-Oct.
This species is included as the representative of a group of somewhat
similar species occurring with conifers, especially pines, and with reddish
brown pilei and the lamellae staining reddish. From our herbarium records
this appears to be the commonest species.
T. flavobrunneum (Fr.) Kummer also has a farinaceous odor but the stipe
is sulphur-yellow within and the lamellae are pale sulphur-yellow. T. albo-
brunneum (Fr.) Kummer has a faint farinaceous odor, the pileus is minutely
striate with innate fibrils, and the stipe is somewhat squamulose above.
T. transmutans Peck has a farinaceous odor but the taste of the surface of the
pileus is bitter. T. ustale (Fr.) Kummer lacks the farinaceous odor and the
pileus is glabrous and viscid, whereas T. imbricatum (Fr.) Kummer, which
also lacks the farinaceous odor, is dry and the surface of the pileus breaks up
into rather coarse, more or less imbricate scales.
