Status:

Found solitary or in groups on ground or decaying wood in forests.

Description:

Fruiting body: Some shade of brown covered with coarse warts/scales; mostly spherical; tough skin. Spores: Firm white mass when young, becoming marbled gray/purplish/black, finally becoming blackish/brownish at maturity. Skin rots away exposing powdery spores (J. Solem, pers. comm).
