reads. The sub-hymenium is very thin and composed
of small cells; the =basidia= are clavate, 25--30 x 9--10 mu, and
four-spored. The =spores= are dull rose color on paper, subgloblose,
5--8 mu in diameter, angular with 5--6 angles as seen from one side. The
=stem= is the same color as the pileus, but considerably lighter. It is
hollow with white fibers within, fibrous striate on the surface,
twisted, brittle, and somewhat cartilaginous, partly snapping, but
holding by fibers in places, cylindrical, even, ascending, with delicate
white fibers covering the lower end.

LEPTONIA Fr.

In _Leptonia_ the stem is cartilaginous, hollow or stuffed, smooth and
somewhat shining. The pileus is thin, umbilicate or with the center
darker, the surface hairy or scaly, and the margin at first incurved.
The gills are adnate or adnexed at first, and easily separating from the
stem in age. Many of the species are bright colored.

[Illustration: FIGURE 142.--Leptonia asprella. Cap hair brown (mouse
colored), minute dark scales at center, stem same color, but sometimes
reddish brown, green or blue, gills flesh color.]

=Leptonia asprella= Fr.--This species occurs on the ground in woods or
in open grassy places. The plants are 3--5 cm. high, the cap 2--4 cm.
broad, and the stem 2--3 mm. in thickness.

The =pileus= is convex, then more or less expanded, umbilicate, rarely
umbonate, hair brown (mouse colored), with dark scales on the center and
minute scales over the surface, striate.

The =gills= are sinuate to adnexed. The =spores= are strongly 5--6
angled, 10--12 x 8--10 mu. The =stem= is smooth, even, usually the same
color as the cap, but sometimes it is reddish brown, green, or blue.

Blowing Rock, N. C., during September, 1899.

=Leptonia incana= Fr., is a more common species, and is characterized by
an odor of mice.

ECCILIA Fr.

The genus _Eccilia_ corresponds with _Omphalia_ of the white-spored
agarics. The stem is cartilaginous, hollow or stuffed. The pileus is
thin and somewhat membranaceous, plane or depressed at the center, and
the margin at first incurved. The gills are more or less decurrent.
