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 aurantiacum

Sporocarps in small groups, stalked, c. 1.5 mm total height . Sporotheca dull orange, red-brown around the stalk apex, 0.5-0.6 mm diam., hemispherical or oblate-subglobose. Hypothallus discoid , rather dark, sometimes confluent . Stalk over 50% of the total height, rather slender, grooved , the base wide, attenuate upwards, red-brown in reflected light, translucent orange brown by TL , with little or no refuse matter, apically sometimes with some calcic globules , plicate throughout. Peridium sub-cartilaginous, double , orange, filled with lime globules. Dehiscence by splitting above into 4-5 revolute lobes , orange inside and without. Columella slightly clavate , mostly filled with lime globules, reaching up to 50% the sporotheca. Capillitium dark, especially centrally, slender, rather simple , sparingly branched, inter-connected only near the tips by small pale membranes . Spores pale grey, distinctly verruculose , subglobose, (10-)11(-12) µm diam.
