pulverulent, globose ; stalks white, thickened at the base, cottony,

The filmy reticulate mycelium at length disappears, and the peridia 
are scattered, looking at first sight, from their white stems, like 
Diachcea. The species is altogether distinct from Trichia lateritia 
Lev. The dust of the peridia consists of irregular fragments of a 
bright orange-red.
