None in PDD

Fruiting body a stalked (or occasionally sessile) sporangium to rarely subplasmodiocarpous, usually gregarious, 1.0–1.5 mm tall. Sporotheca subglobose to turbinate or obovoid to cyathiform or cylindrical, erect, 0.3–0.7 mm in diameter. Stalk cylindrical or expanded upward, sometimes slightly flattened, plicate, reddish brown, translucent, up to one-half the total height, rarely absent. Hypothallus inconspicuous, small, circular, thin, membranous, colourless or light bright in the centre. Peridium membranous, calcareous and white or yellowish white above, ochraceous to yellow-brown or red-brown below, the lower portion persisting as a cartilaginous, ochraceous to reddish brown calyculus, dehiscence circumscissile or sometimes rather irregular. Columella absent. Capillitium physaroid, consisting of large, irregular, white, ochraceous or yellow lime nodes and slender, branching, hyaline connecting filaments with frequent membranous expansions at the junctions, sometimes forming a prominent, central pseudocolumella. Spores black in mass, violaceus brown by transmitted light, 7–9 µm in diameter, minutely verrucose or spinulose. Plasmodium yellow.

This species can be recognised on the basis of having a sporangium that is white above and yellow-brown to reddish-brown below. Several varieties have been described for Craterium leucocephalum, but all of these appear to be linked by intergrading forms (Martin & Alexopoulos 1969) and thus are hardly worth recognising.
