Hypothallus forming a narrow rim around the base of the sporocarp. Stalk thick, calcareous, grooved, ochraceous. Peridium double, domed, the outer layer an egg-shell crust of compacted crystals, the inner layer membranous. Dehiscence circumscissile, allowing the peridium to fall off as a lid, leaving a cup-like base. Columella hemispherical, large, ochraceous to pale red. Capillitium radiating from the columella, consisting of rigid, sparingly branched threads, hyaline or lilac- or yellow-brown, with a few swellings containing calcareous deposits. Spore-mass black.
