the plant.

The pileus is one to three inches broad, fleshy, convex, then expanded,
plane, slightly umbonate, sometimes depressed, or flexuous and
irregular, margin at first involute, dingy or reddish-yellow, at first
silky, becoming smooth and even.

The gills are rather thick, narrowed behind, emarginate or acutely
adnate, sulphur-colored.

The stem is two to four inches long, somewhat bulbous, sometimes curved,
frequently slightly striate; stuffed, often hollow; sulphur-yellow,
yellow within; furnished at the base occasionally with many rather
strong, yellow, fibrous roots. Odor strong and disagreeable. Flesh thick
and yellow. Spores are 9-10x5u.

It grows in mixed woods. I find it frequently where logs have decayed.
The specimen in Figure 46 was found in Haynes' Hollow and photographed
by Dr. Kellerman. Found in October and November.

_Tricholoma quinquepartitum. Fr._

Quinquepartitum means divided into five parts. There is no apparent
reason for the name. Fries could not identify Linnaeus' Agaricus
quinquepartitus and he attached the name of this species.

The pileus is three or four inches broad, slightly fleshy; convex,
rather involute, then flattened, somewhat repand; viscid, smooth, even,
pale yellowish.

The gills are notched at the point of attachment to the stem, broad,
white.

The stem is three to four inches long, solid, striate or grooved,
smooth. The spores are 5-6x3-4.

This species differs from T. portentosum in the pileus not being
virgate, and from T. fucatum in the smooth, striate or grooved stem.
This plant is found in thin woods where logs have decayed. I have not
eaten this species but I have no doubt of its edibility. The taste is
pleasant. Found in October and November.

_Tricholoma laterarium. Pk._

[Illustration: Figure 47.--Tricholoma laterarium.]

Laterarium is from _later_, a brick; so called because there is nearly
always a slight tinge of brick red on the disk.

The pileus is two to four inches broad, convex, then expanded, sometimes
slightly depressed in the center; pruinose, whitish, the disk often
tinged with red or brown, the thin margin marked with slight subdistant,
short, radiating ridges.

The gills are narrow, crowded, white, prolonged in little decurrent
lines on the stem. The stem is nearly equal, solid, white. The spores
are globose, .00018 inch in diameter. _Peck's_ 26th Rep.

This plant is quite widely distributed in the United States. It is found
