H ab. On the putrefying hoofs of the horse ; the hoofs and horns of the ox,
and other animals ; rare. Autumn.
Gregarious, white, two lines to a quarter of an inch high. Stipes firm, thick,
solid. Head globose, often flattened or depressed, one to near two lines
in diameter. Peridium white, somewhat pulverulent, or, appearing rather
like a delicate white crust than a membrane, at length bursting
and falling off irregularly, leaving the mass of pale reddish-brown, globose
ovate, pellucid sporidia, retaining its round form for a long time,
in consequence of some adhesion between the sporidia themselves,
though unaccompanied by filaments.
