The two or three glumes at the base are tolerably perfect, while the top
looks as if it had been pinched up into a point when young, and afterwards
charred. The outer coat is black and glossy, studded here and there with
minute punctures, surrounded like a little eyelet hole, with a white border,
which leads down to a subglobose cell, the walls of which are clothed with a
white or greyish gelatinous mass of spores.—M. J .B .
