tem rosy-red, the cap may be red and the stem white
or whitish with stains of red. During wet weather the caps of all are
viscid; when dry, all may be cracked more or less. The stems may not be
scaly at the apex, often rosy when young. They are found in the woods
solitary, in groups, or frequently in dense clusters. The specimens in
Figure 51 were found in Michigan and photographed by Dr. Fischer.

I found this plant in Poke Hollow. The gills were quite decurrent.

_Tricholoma acerbum. Bull._

THE BITTER TRICHOLOMA.

Acerbum means bitter to the taste.

The pileus is three to four inches broad, convex to expanded, obtuse,
smooth, more or less spotted, margin thin, at first involute, rugose,
sulcate, viscid, whitish, often tinged rufous, or yellow, quite bitter
to the taste.

The gills are notched, crowded, pallid or rufescent, narrow.

The stem is solid, rather short, blunt, yellowish, squamulose above or
about the apex. The spores are subglobose, 5-6u.

These plants were found growing in a thick bed of moss along with
Armillaria nardosmia. They were not perfect plants but I judged them to
be T. acerbum from their taste and involute margin. I sent some to Prof.
Atkinson, who confirmed my classification. They grow in open woods in
October and November.

_Tricholoma cinerascens. Bull._

Cinerascens means becoming the color of ashes.

The pileus is two to three inches broad, fleshy, convex to expanded,
even, obtuse, smooth, white, then grayish, margin thin.

The gills are emarginate, crowded, rather undulate, dingy, reddish often
yellowish, easily separating from the pileus.

The stem is stuffed, equal, smooth, elastic.

They grow in clusters in mixed wood. They are mild to the taste.

_Tricholoma album. Schaeff._

THE WHITE TRICHOLOMA. EDIBLE.

[Illustration: Figure 52.--Tricholoma album. Entirely white.]

Album means white.

The pileus is two to four inches broad, fleshy, entirely white, convex,
then depressed, obtuse, smooth, dry, disc frequently tinged with yellow,
margin at first involute, at length repand.

The gills are rounded behind, rather crowded, thin, white, broad.

The stem is two to four inches long, solid, firm, narrowed upwards,
smooth.

This plant is quite plentiful in our woods, growing usually in groups.
It grows upon the leaf mould and is frequently quite large. It is quite
acrid to the taste when raw, but this is overcome in cooking. It is
found from August to October.
