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.
Physical Description
Species Didymium clavus
Plasmodium colourless or grey. Sporocarps stalked, up to 1 mm high. Hypothallus discoid and dark. Stalk 0.2-0.8 mm long, cylindrical, stout, grooved , black and opaque from refuse matter. Sporotheca discoid with a wide, dark, basal umbilicus, 0.2 mm thick and 0.5-1 mm diam., white. Peridium with a thickened basal plate , purple-brown and, with the exception of the basal plate, dusted with white stellate lime crystals which are larger than the spores. Dehiscence into fragments above. Columella absent. Capillitial threads abundant, thin, sparsely dichotomously branched, colourless or pale purple, radiating from the basal plate. Spore-mass dark brown. Spores almost colourless, (5-)6-8 µm diam., with widely spaced, very fine, pale warts, sometimes cluster-warted.
Habitat
Typically found at an altitude of 0 to 4,653 meters (0 to 15,266 feet).Mean = 388.410 meters (1,274.311 feet), Standard Deviation = 740.790 based on 477 observations. Altitude information for each observation from British Oceanographic Data Centre.
