Not common. Foxhall, Captain W auch— In Fngland, I believe it has
been found only by the Rev. Charles A bbott of Bedford, from whose
specimens Mr Sowerby made his drawing.
Gregarious, often confluent (several growing into each other), scentless, <
brittle, whitish, at length yellowish, and more or less tinged with reddish
brown. Stipes h a lf an inch or less to an inch in height, variable
in thickness, attenuated at the base, central or lateral, horizontal or
even vertical, according to circumstances, rarely wanting. Pileus generally
somewhat more than an inch in breadth, depressed; the margin
sometimes lobed, and often irregular, from the propensity of the
pilei to coalesce. Processes o f the hymenium wliitish, distinct, thin, entire
or laciniate, curved or gyrose, never forming p ores; producing
fructification on both sides. Sporidia globose, often adhering in little
clusters to the extremities of the processes.
Of the species formerly referred to the genus Sistotrema,
F r i e s has retained only the one now described. He observes
