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 cingulatum var. rimosum
Sporocarps , sessile, crowded on an extensive calcareous white hypothallus, ± isodiametric, polygonal, with raised ridges dividing the polygons, white, 0.5-1 mm diam. Peridium of two closely adherent layers, the inner layer membranous, red-brown at the base , colourless above, with a very few included lime globules , the outer a thick, brittle, calcareous crust composed of packed lime globules. Dehiscence along the ridges, either leaving a cup which is rather persistent when the top platelets have dropped away or splitting to the base. Columella large, pale brown to off-white, rugose , subglobose to hemispherical, filled with, often crystalline, lime. Capillitium of abundant, ± undulate , radiating threads and flattened, perforated strands up to 3 µm wide, dichotomously branched. Spore-mass dark brown. Spores pale red-brown, 8-10 µm diam., with rather widely and irregularly placed, rather dark irregular small warts , and often a few pressure lines that form a broken reticulum .
