mycelial bull) at the base. Gleba of capillitium ami spores; capillitium co])ious,

pubescent). — Peridium depressed-globose, up to fin. (10 mm.) high, ^in. (20 mm.) 
diameter; exoperidium persistent, dingy brown, almost black, in the nature of 
almost coarse mycelial fibres mixed with vegetable debris ; endoperidium
