Overview | |
Sporocarps densely clustered but not heaped, sessile, hemispherical, pulvinate on a broad base, occasionally slightly elongated, 1-2 mm diam., light bluish grey, grey or steel-grey. Peridium appearing single, thin, fragile, smooth to minutely rugose to wrinkled, the wrinkles often forming a distinct reticulum, with scanty deposits of lime globules. Dehiscence from above as irregular fragments. Hypothallus inconspicuous, often evident as a non-calcareous ring at the base of each sporocarp or extremely thin, transparent and appearing absent. Columella either absent or present, when present, reduced to a slight mound at the base of the sporotheca, white to cream coloured, calcareous. Capillitium extremely dense, consisting of straight, rigid, dark purplish brown threads, paler at the extremities, often branched and anastomosed, but not forming a distinct net, the apices persistently attached to the peridial fragments. Spore-mass purple-brown. Spores violet-brown distinctly and uniformly warted, 10-12(-16) µm diam. Plasmodium unknown. Nivicole.
