INOCYBE Fr.

In the genus _Inocybe_ there is a universal veil which is fibrillose in
character, and more or less closely joined with the cuticle of the
pileus, and the surface of the pileus is therefore marked with fibrils
or is more or less scaly. Sometimes the margin of the pileus possesses
remnants of a veil which is quite prominent in a few species. The gills
are adnate, or sinuate, rarely decurrent, and in one species they are
free. It is thus seen that the species vary widely, and there may be,
after a careful study of the species, grounds for the separation of the
species into several genera. One of the most remarkable species is
_Inocybe echinata_ Roth. This plant is covered with a universal veil of
a sooty color and powdery in nature. The gills are reddish purple, and
the stem is of the same color, the spores on white paper of a faint
purplish red color. Some place in it _Psalliota_. Collected at Ithaca in
August, 1900.

TUBARIA W. Smith.

In the genus _Tubaria_ the spores are rust-red, or rusty brown
(ferruginous or fuscous-ferruginous), the stem is somewhat
cartilaginous, hollow, and, what is more important, the gills are more
or less decurrent, broad next to the stem, and thus more or less
triangular in outline. It is related to _Naucoria_ and _Galera_, but
differs in the decurrent gills. The pileus is convex, or with an
umbilicus.

=Tubaria pellucida= Bull.--This species grows by roadsides in grassy
places. The plants are from 3--4 cm. high, and the cap 1--2 cm. in
diameter, and the stem 2--3 mm. in thickness.

[Illustration: FIGURE 153.--Tubaria pellucida. Dull reddish brown
(natural size).]

The =pileus= is conic, then bell-shaped, often expanded and with a
slight umbo; the color is dull, reddish brown, and it has a watery
appearance. The plant is sometimes enveloped with a loose and delicate
universal or outer veil, which remains on the margin of the cap in the
form of silky squamules as shown in the figure. The margin of the pileus
is faintly striate. The =gills= are only slightly decurrent. Figure 153
is from plants (No. 2360 C. U. herbarium) collected along a street in
Ithaca.

The stem is at first solid, becoming hollow, tapering above, and the
apex is mealy.

CREPIDOTUS Fr.

In _Crepidotus_ the pileus is lateral, or eccentric, a
