#1. Sporocarps dispersed or in small groups, erect, stalked, 1-4 mm tall, rarely almost spherical, but usually cylindrical, 0.5-0.8 mm diam., almost white, pale grey, beige, or rarely ochraceous. Stalk concolorous with the sporotheca or darker. Calyculus smooth or minutely reticulate on the inside. Capillitial net usually small-meshed, expanding slightly upwards to 1.5 x the original height, firmly connected to the cup, tubules in the centre and base of the sporotheca 4-6 µm diam. and strongly warted or spinulose, the basal threads smooth or nearly so, at the periphery covered with spines and half rings, 2-4 µm diam. Spores almost colourless, covered with very fine warts (oil-immersion) and a few larger warts, (6-)7-8 µm diam.
#2. SPOROCARPS: stalked, scattered to gregarious some times united by their fused stalks and accruing in digitate clasters of 2 -20 sporangia 0.3 – 0.4 mm tall. Sporotheca ovate to cylindrical, usually tapering towards the apex, pale grey to light brown, ochraceous or sometimes yellowish brown, 0.1 – 0.8 mm in diameter.
STALK: slender, pallid or black up to 2 mm length. Hypothallus discoid or contiguous for a group of sporangia, transparent and often not evident.
PERIDIUM: persisting as a shallow calycus in mature fruiting bodies only, with a smooth, delicately stippled, finely reticulate inner surface.
CAPILLITIUM: consisting of a network of threads 2 – 6 µm in diameter and densely covered with small blunt spines (occasionally also with cogs, bands or reticulations), firmly attached to the calyculus.
SPORES: Pale grey or light yellow in mass, colourless by transmitted light, with a few scattered warts 6 – 7µm in diameter.
PLASMODIUM: White less often grey or pale yellow.
HABITAT: Decaying wood, leaf litter and dung.
NOTES: This species has two diffrent forms ovate or cylindrical and two diffrent colours grey or ochraceous.
