derived. The plants grow on the ground or on very rotten wood in woods
during late spring and in the summer. The plant is not very common in
this country, but appears to be widely distributed both in Europe and
here, having been collected in Carolina, Ohio, Vermont, New York, etc.
The plants are 12--20 cm. high, the cap 2--2.5 cm. broad, and the stem
4--7 mm. in thickness.

The =pileus= is fleshy, tough, convex or bell-shaped, then expanded,
sometimes umbonate, or in age sometimes the margin upturned and more or
less wavy, not viscid, but finely striate when damp, thin. The color
varies from vinaceous cinnamon to chestnut or light leather color, or
tawny, paler in age, and sometimes darker on the center. The =gills= are
sometimes more or less crowded, narrow, 5--6 mm. broad, adnate, but
notched, and sometimes becoming free from the stem. The color is light
leather color, brick red or bay, the color and color variations being
due to numbers of colored cystidia or spicules scattered over the
surface of the gills and on the edge. The =cystidia= are fulvous,
fusoid, 75--90 mu long. The =spores= are oval, white, small, 6 x 3 mu.
The =stem= is long and slender, nearly cylindrical, tapering somewhat
above, slightly enlarged below, and rooting. The color is the same as
that of the pileus or dark bay brown, and shining, and seems to be due
to large numbers of spicules similar to those on the gills. The color is
paler below in some cases, or gradually darker below in others. The
stems are bound together below by numerous threads.

Figure 130 is from plants (No. 2373, C. U. herbarium) collected in woods
near Freeville, N. Y. The plants have been collected near Ithaca on
three different occasions, twice near Freeville about nine miles from
Ithaca, and once in the woods at Ithaca. It is easily distinguished by
its color and the presence of the peculiar setae or cystidia.

Although the plant has been collected on several different occasions in
America, it does not seem to have been recognized under this name until
recently, save the record of it from Carolin
