P/arei] resupinate, spreading, 3-6 inches in length or more, and 2-3 inches
in breadth, of a dry thin substance, following most closely every inequality
of the bark, the margin not in the least byssoid, forming roundish
irregular lobes. The surface is nearly destitute of papillce, even, or
more or less rugged, according to the nature of the bark beneath, thickly
set with exceedingly minute, short bristles. The colour is opaque,
ferruginous-brown, with sometimes a slight purplish tinge, and a grey
bloom, as if it had been covered with a very thin wash of white body-
colour. Bristles under the microscope jointed. Sporidia globose, very
minute.
