Sporocarps sessile, crowded on an extensive, white, calcareous hypothallus, subglobose, rugose, 0.4-0.6 mm diam. Peridium of two, ▒ adherent layers, the inner layer membranous, either pale yellow-ochraceous at the base and hyaline above, or hyaline throughout, the outer layer densely calcareous, with scale-like thickenings making the whole peridium rough or bulbous. Columella subglobose, white, smooth or rugose, filling only 20-25% of the diam. of the sporotheca, lime in the columella mostly crystalline. Capillitium radiating, yellow brown to dark brown, round or flattened, flexuose, dichotomously branched, the angles sometimes with membraneous expansions, cross-bars very rare. Spore-mass dark brown.
