Diderma antarcticum

Description

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.

Physical Description

Species Diderma antarcticum

Sporocarps sessile, closely aggregated in groups of 10-50 or more. Sporothecae dark reddish brown, subglobose or angular from mutual pressure . Peridium double , the outer wall thick, brittle above, persistent and cartilaginous below, closely united with the delicate membranous inner layer upon which minute white lime globules are densely scattered . Capillitium rather scanty, the threads coarse or slender, dark in the centre, pale at the tips , occasionally with pale brown membranous expansions from which the threads radiate . Columella rough, indeterminate, calcareous, pale yellow. Spore-mass black. Spores dark purplish brown and encircled by a pale band, minutely spinulose , often bearing one or more raised bands , 10.5-11.5 µm diam. Plasmodium unknown.
