Overview
Sporocarps stalked, gregarious, solitary, or united in simple or compound, corymbose clusters. Sporothecae appearing globose or somewhat irregular or lobed, 0.4-0.7 mm diam., in reality discoid and deeply reflexed, white or greyish. Peridium thin, membranous, fragile, translucent, densely covered with a white, powdery layer of stellate crystals. Stalk white or pale yellowish to ochraceous, smooth, subulate, 1-1.3 mm long, with an opaque core of coarse, not stellate, lime crystals and a hyaline cortex. Hypothallus extensive, branching, white and calcareous at the bases of the stalks, elsewhere colourless or nearly so. Columella small, dome-shaped, inconspicuous, its place largely taken by the inverted sporotheca base. Capillitium profuse, colourless, delicate, freely branched and anastomosed. Spore-mass black. Spores dark violaceous brown, densely covered with long, dark spines arranged to form a partial and irregular reticulum and apparently immersed in a gelatinous surface layer, 10-12 µm diam. Plasmodium unknown.
