uite thick when the plant is young.
It is scaly on the under side, clinging to the margin of the pileus in
triangular remnants, appearing like a crown. The color of the veil and
of its remnants is the same as the color of the scales of the cap.

The spores in mass are light brown, and when fresh with a slight purple
tinge. (The color of the spores on white paper is near walnut brown or
hair brown of Ridgeway's colors.) Under the microscope they are
yellowish, oval or short oblong, often inequilateral, 6--8 x 4--5 mu.

Figure 151 is from plants (No. 4016, C. U. herbarium) collected at
Blowing Rock, N. C., September, 1899, on a fallen maple log. The plants
sometimes occur singly. It has been collected at Ithaca, N. Y., and was
first described from plants collected at Waynesville, Ohio.

=Flammula sapinea= Fr., is a common plant growing on dead coniferous
wood. It is dull yellow, the pileus 1--4 cm. in diameter, and with
numerous small scales.

HEBELOMA Fr.

In _Hebeloma_ the gills are either squarely set against the stem
(adnate) or they are notched (sinuate), and the spores are clay-colored.
The edge of the gills is usually whitish, the surface clay-colored. The
veil is only seen in the young stage, and then is very delicate and
fibrillose. The stem is fleshy and fibrous, and somewhat mealy at the
apex. The genus corresponds with _Tricholoma_ of the white-spored
agarics. All the species are regarded as unwholesome, and some are
considered poisonous. The species largely occur during the autumn. Few
have been studied in America.

=Hebeloma crustuliniforme= Bull.--This plant is usually common in some
of the lawns, during the autumn, at Ithaca, N. Y. It often forms rings
as it grows on the ground. It is from 5--7 cm. high, the cap 4--8 cm. in
diameter, and the stem is 4--6 mm. in thickness.

The =pileus= is convex and expanded, somewhat umbonate, viscid when
moist, whitish or tan color, darker over the center, where it is often
reddish-brown. The =gills= are adnexed and rounded near the stem,
crowded, whitish, then clay color and reddish-brown, the edge whitish
and irregular. The =gills= are said to exude watery drops in wet
weather. The =stem= is stuffed, later hollow, somewhat enlarged at the
base, white, and mealy at the apex. Figure 152 is from p
