Overview
Sporocarps stalked, gregarious, sometimes crowded, erect or nodding. Sporothecae globose or depressed, 0.4-0.6 mm diam., usually umbilicate below, grey, brownish grey, or bronze, depending upon the amount of lime present. Peridium thin, metallic, with limy scales on the surface. Dehiscence floriform into 6-12 segments. Stalk calcareous, white or yellowish, often shading to fuscous or black below, rather long, tapered upwards. Hypothallus inconspicuous. Capillitium delicate, white or colourless, the nodes usually forming a central pseudocolumella, the remaining nodes few, small, oval or sub-fusiform, many junctions of the net limeless. Spore-mass brown. Spores pale violet-brown, minutely punctate, 8-10 µm diam. Plasmodium pale grey.
