(L.) Wettst
Description:
SPOROCARPS: stalked, gregarious to crowded but occasionally scattered, 2 to 6 mm. Sporotheca ovate to cylindrical, pinkish red to brick red 0.4 - 1.2 wide.

STALK: slender, sriate, same colour as the sporotheca or darker 0.5 -1.5 mm long. Hypothallus ether small and inconspicuous under individual sporangia or contiguous for a group of sporangia, reddish brown with a silvery sheen.

PERIDIUM: persisting as a shallow calycus in mature fruiting bodies only, shining, plicate, smooth or nearly so.

CAPILLITIUM: consisting of a network of threads 3 - 4 µm in diameter and marked with cogs and half-rings, firmly attached to the whole surface of the calyculus.

SPORES: Red or reddish brown in mass, colourless by transmitted light, with a few scattered warts 6 - 8 µm in diameter.

PLASMODIUM: White.
