broad, flesh color when moist, whitish when dry, convex,
then flattened, obtuse or gibbous, margin at first involute, then
flattened and slightly striate. +Stem+++ 2 to 4 inches long, 1 to 2
lines thick, very hollow (fistulose), rigid, fragile, slightly tapering
upward, rarely compressed, very smooth, except the base, even, color
brown or reddish-brown. +Gills+ are at first adnexed, soon free,
crowded, linear, narrow, plane, flesh color and then whitish. It grows
in tufts (caespitose). The stems are sometimes white, tomentose at the
base. Stevenson says the cap is flesh color, but our specimen was of a
pale or tan brown color, less than 2 inches broad; when moist it was
much paler. Found in mixed woods in September.

+PSATHYRELLA DISSEMINATA = scattered.+
+The Widely-spread Psathyrella.+

+Cap+ a light-colored yellowish-brown, changing into an ash color; the
disc with a yellowish shade; of an oval shape, then bell-shaped, and
marked with lines, almost sulcate. The margin does not extend beyond the
gills. It is a small mushroom, measuring from 2 or 3 lines across the
cap to 1 inch. +Stem+ about 1 inch long or more, fragile, hollow,
sometimes curved and bending, smooth and light-colored. +Gills+ adnate,
rather broad, slightly narrowed at both ends, at first whitish and then
turning a brownish color. The plants vary greatly in height and size,
are sometimes caespitose and at other times scattered. The disc in some
specimens was slightly raised in the middle, almost umbonate. It was
found about stumps and on the ground, at the end of May, in mixed woods.
It soon withers, but does not melt into fluid.

+HYPHOLOMA CAPNOIDES = smoke.+
+The Gray-gilled Mushroom.+

+Cap+ is reddish-brown, 1 to 3 inches broad, fleshy, convex, then
flattened, obtuse, dry, smooth. The margin in our specimen was slightly
revolute. Flesh white. +Stem+ 2 to 3 inches long, 2 to 4 lines thick,
growing together at the base (connate), hollow, equal, often curved,
becoming silky, even, whitish at apex, and here and there striate.
+Gills+ gray color, adnate, easily separating, rather broad, waxy. The
name is given on account of the smoke-colored gills. It is not common,
and is generally found on or about stumps in the autumn.

+HYPHOLOMA PERPLEXUM = perplexing.+
+The Perplexing Hypholoma.+

+Cap+ brownish and turning to yellow, 1 to 3 inches broad and slightly
