On dead herbaceous stems. Winter. [United States.]
Forming a thin, black, velvety stratum, easily recognised under a lens
by tbe globose beads witb which tbe hairs of the pile are terminated.
Scarcely i a line high ; stem stiff, brown, obscurely annulated; spores
large, globose, pellucid, brown, minutely eehinulate. The apex of the
stem is generally a little incrassated, forming a receptacle for the sporidia.

spores globose, smooth.—Berk. Ann. N.H. no. 226,1.13,/. 16.
On dead leaves of grass. King’s Cliffe, &c.
Extremely minute, not one-fourth of a line high, dark black; stem slender
with 4-5 articulations ; heads globose ; spores globose, smooth, with a globose
nucleus. The whole plant is dark, so th at it requires a good light to
see the articulations of the stem, which are, however, very evident.—
