Genus Diderma

Sporocarpous, plasmodiocarpous or occasionally pseudo-aethaloid. Peridium with granular lime, typically double , but can be single or triple. In the latter case, crystalline lime may be present in the middle layer. Columella usually conspicuous but sometimes reduced to a thickened base . Capillitium lime-free, consisting of branched and anastomosed threads.

Species Diderma cingulatum var. rimosum f. pallidosporum

Sporocarps crowded, sessile. Sporothecae smooth or minutely bullate from small heaps of lime, white, subglobose, 0.5(-1) mm diam. Columella obsolete . Peridium double , the outer layer a lime crust, the inner layer membranous, hyaline , holding some white lime globules . Dehiscence irregular, the layers separate. Capillitium profuse, brown, simple or branched 1-2 times, strongly fenestrate (the narrowly acute axils with numerous cross-bars or small-meshed nets ), flexuose, slightly undulate , radiating from the base to the peridium and with numerous irregular dark warts . Spores pale violet-brown, with a pale line, 19 µm diam., rather densely, distinctly verruculose .
