Overview | |
Sporocarps scattered to densely clustered, usually sessile, globose, oval to obovate, usually constricted at the base, 1.0-1.5 mm diam., white to cream coloured. Hypothallus large, continuous, venulose, white, usually calcareous. Peridium double, outer layer free from the inner layer, consisting of a thick calcareous crust, brittle, usually smooth but occasionally wrinkled, inner layer thin, membranous, white when lime is present, brownish when lime is lacking. Stalk, when present, as a white or cream-coloured extension of the hypothallus, furrowed, rarely attaining more than 33% of the total height. Columella conical to clavate, white, often attaining 50% of the sporotheca, occasionally reaching the apex and there confluent with the peridium and then the sporotheca apex is usually umbilicate. Capillitium dense, persistent, threads brown with the bases and extremities colourless, flexuose, branched and anastomosed to form a dense reticulum with few free ends, often expanded in the axils. Spore-mass purple-brown. Spores violet-brown, verrucose, 10-12 µm diam., paler, smoother and occasionally thicker on one side, the warts often variable in size and sometimes irregularly distributed. Nivicole.
