d summer.

The pileus is thin, adnate behind, somewhat extended, more or less
fan-shaped or kidney-shaped, simple, often much lobed, narrowed behind
to the point of attachment; whitish, downy, then strigose.

The gills are radiating, gray, then brownish-purple, and sometimes
white, branched, split along the edges and rather deeply rolled
backwards. The spores are nearly round, 5-6u.

This is a very common species all over the world. I found it in the
winter of 1907 on decayed shade-trees along the streets of Chillicothe.
It seems to be partial to maple timber. Some call this S. alneum. It is
very easily identified from its purple gills being split.

_Trogia. Fr._

Trogia is so called in honor of the Swiss botanist, Trog.

The pileus is nearly membranaceous, soft, quite tough, flaccid, dry,
flexible, fibrillose, reviving when moist.

The gills are fold-like, venose, narrow, irregular, crisped.

_Trogia crispa. Fr._

Crispa means crisp or curled. The pileus tough, cup-shaped, reflexed,
lobed, villous, whitish or reddish toward the attachment, often
tan-colored.

The gills are quite narrow, vein-like, irregular, more or less branched,
blunt on the edge, white or bluish-gray, quite crisped, edge not
channeled.

The caps are usually very much crowded and imbricated. It revives during
wet weather and is found throughout the year, generally on beech limbs
in our woods.

CHAPTER III.

THE ROSY-SPORED AGARICS.

The spores of this series are of great variety of color, including rosy,
pink, salmon-color, flesh-color, or reddish. In Pluteus, Volvaria, and
most of Clitopilus, the spores are regular in shape, as in the
white-spored series; in the other genera they are generally irregular
and angular. There are not so many genera as in the other series and
fewer edible species.

_Pluteus. Fr._

Pluteus means a shed, referring to the sheds used to make a cover for
besiegers at their work, that they might be screened from the missiles
of the enemy.

They have no volva, no ring on the stem. Gills are free from the stem,
white at first then flesh-color.

_Cervinus is from cervus, a deer._ The pileus is fleshy, bell-shaped,
expanded, viscid in wet weather, smooth, except a few radiating fibrils
when young, margin entire, flesh soft
