ge, the edge of the gills sometimes almost or quite
white, violet, rose.

The stem is even, nearly naked, somewhat villous at the base, sometimes
almost white when young, later assuming the color of the cap, hollow,
smooth.

The spores are white and oblong, 6-8x3-3.5. M. Pelianthina differs
from this in having dark-edged gills. It differs from M. pseudopura and
M. zephira in having a strong smell. M. ianthina differs in having a
conical cap.

This plant is quite widely distributed. Our plants are light-violet in
color, and the color seems constant. I have found it in mixed woods. It
is found in September and October.

_Mycena vulgaris. Pers._

Vulgaris means common.

The pileus is small, convex, then depressed, papillate, viscid,
brownish-gray, finely striate on the margin.

The gills are subdecurrent, thin, white; the depressed cap and decurrent
gills make the plant resemble an Omphalia. Spores, 5x2.5u.

The stem is viscid, pale, tough, fibrillose at the base, rooting,
becoming hollow. It differs from M. pelliculosa in not having a
separable cuticule and the fold-like gills.

This plant will be recognized by its smoky or grayish color, umbilicate
pileus, and viscid stem. It is found in woods on leaves and decayed
sticks. August and September.

_Mycena epipterygia. Scop._

[Illustration: Figure 96.--Mycena epipterygia.]

Epipterygia is _Epi_, upon, and _Pterygion_, a small wing.

These are small, the pileus being one-half to one inch broad,
membranaceous, bell-shaped, then expanded, rather obtuse, not depressed,
striate, the cuticule separable in every condition and viscid in damp
weather, gray, often pale yellowish-green near the margin often minutely
notched when young.

The gills are attached to the stem with a decurrent tooth, thin, whitish
or tinged with gray.

The stem is two to four inches long, hollow, tough, rooting, viscid,
yellowish, sometimes gray or even whitish. The spores are elliptical,
8-10x4-5u.

These plants have a wide distribution and [are?] found on branches,
among moss and dead leaves. They are found in clusters and solitary.
They resemble in many ways M. alcalina but do not have the peculiar
smell.

The plants in Figure 96 were photographed by Prof. G. D. Smith of Akron.

_Omphalia. Fr._

Omphalia is from a Greek word meaning the navel; referring here to the
central depression in the cap.

The pileus from the first is centrally depressed, then funnel-shaped,
