whitish, varying to grayish brown or dark brown,
the center sometimes darker than the margin, as is usual in many plants.
The surface of the pileus is often marked in radiating streaks by fine
dark hairs. The =gills= are white, very broad, adnexed, and usually
deeply and broadly notched next the stem. In age they are more or less
broken and cracked. The =spores= are white, elliptical, 7--10 x 6--7 mu.

The plant resembles somewhat certain species of _Tricholoma_ and care
should be used in selecting it in order to avoid the suspected species
of _Tricholoma_.

MYCENA Fr.

The genus _Mycena_ is closely related to _Collybia_. The plants are
usually smaller, many of them being of small size, the cap is usually
bell-shaped, rarely umbilicate, but what is a more important character
the margin of the cap in the young stage is straight as it is applied
against the stem, and not at first incurved as it is in _Collybia_, when
the gills and margin of the pileus lie against the stem. The stem is
cartilaginous as in _Collybia_, and is usually hollow or fistulose. The
gills are not decurrent, or only slightly so by a tooth-like process.
Some of the species are apt to be confused with certain species of
_Omphalia_ in which the gills are but slightly decurrent, but in
_Omphalia_ the pileus is umbilicate in such species, while in _Mycena_
it is blunt or umbonate. The spores are white. A large number of the
plants grow on leaves and wood, few on the ground. Some of those which
grow on leaves might be mistaken for species of _Marasmius_, but in
_Marasmius_ the plants are of a tough consistency, and when dried will
revive again if moistened with water.

Some of the plants have distinct odors, as alkaline, or the odor of
radishes, and in collecting them notes should be made on all these
characters which usually disappear in drying. A few of the plants exude
a colored or watery juice when bruised, and should not be confounded
with species of _Lactarius_.

=Mycena galericulata= Scop. =Edible.=--_Mycena galericulata_ grows on
dead logs, stumps, branches, etc., in woods. It is a very common and
very widely distributed species. It occurs from late spring to autumn.
The plants are clustered, many growing in a compact group, the hairy
bases closely joined and the stems usually ascending. The plants are
from 5--12 cm. high, the caps from 1--3 cm. broad, and the slender stems
2--3 mm. in thickness.

The =pileus= is conic to bell-shaped, som
