Description

Genus Didymium

Sporocarpous or plasmodiocarpous. Peridium a thin membrane with a covering of crystalline lime. The peridial lime may be scattered loosely over the surface or united into a crust. Columella or pseudo-columella usually present. Capillitium lime-free, consisting of branched and anastomosed threads, often with nodular thickenings.

Sporocarps scattered , greyish, total height 0.5-0.8 mm. Sporotheca hemispherical, c. 0.7 mm diam. Hypothallus large, by TL red-brown, glossy, concolorous with the stalk and radially veined. Stalk 0.5-0.7 mm long, stout, black or nearly so, umber-brown, translucent , free of granular matter, costate , gradually passing into the peridium where the ribs are converted into veins. Columella none. Peridium with a powdery coating of white lime, colourless above, rather pale rosy-umber beneath , veined at the base . Dehiscence irregular, the flat basal part persistent . Capillitium scanty, consisting of thin, purple-brown and/or colourless, flexuose threads which are attached to the base and connected transversely, and with many irregular, long, dark-brown, often confluent thickenings.
