[Notes from Kew Type specimen, PRJ 2010] Type K(M) 57899. Wood of the type specimen hard, blackened on very surface only, pale inside; matches wood on which this fungus typically found in the forest.

Plants stipitate or substipitate, shallow cup-shaped, 1-1.5 cm. in diameter and about 5 mm. deep, dried plants pale-yellow (probably much brighter when fresh) marked with concentric rings about the outer margin, externally covered with loose cells which sometimes approach rudimentary hairs but with no well developed hairs, wrinkled when dry especially near the base of the cup; stem very short or almost wanting, sometimes not more than 1 mm. in length, never long as in related species; asci cylindric, about 400-475 x 20 µ, gradually tapering below; spores 1-seriate or with the ends slightly overlapping, fusoid with the ends quite strongly narrowed, with one or two large oil-drops and granular within, striations consisting of several broad, longitudinal bands extending the length of the spore, 30-40 x 12-15 µ; paraphyses filiform, scarcely enlarged above.

DISTRIBUTION: West Indies, New Zealand, Australia, and Africa.

The plants of this species examined are almost sessile although the species is often described and illustrated with a stem several mm. long. The stem is probably variable as in other species of the genus although it has never been found to attain the length characteristic of other species of the genus. With the exception of the shorter stem, and absence of hairs the cups of this species might easily be mistaken for a subsessile form of Cookeina sulcipes. The spores however are quite different. Geopyxis Mölderiana P. Henn.² does not seem to differ materially from this species so far as can be judged from the published description.
