Hymenophore annual, readily removed as a thin film, arachnoid-mucedinioid, forming irregularly linear areas to 20 x 4 cm; hymenial surface cream or pallid ochre, even; margin thinning out, concolorous, arachnoid. Context of a few repent hyphae 8-10 µm diameter, walls to 1 µm thick, without clamp connections; fertile hyphae erect, mainly arranged in cymes, bearing terminal clusters of basidia and paraphyses. Basidia cylindrical or subclavate, 12-16 x 8-11 µm, bearing 6, occasionally 8 spores on sterigmata 2-5 µm long. Paraphyses cylindrical or subclavate, 8-10 x 5-7 µm. Spores irregularly fusiform or naviculate, apices bluntly acuminate, sometimes rounded, bases attenuate and apiculate, 7-10 x 3-4 µm, walls smooth, hyaline, 0.1 µm thick.

DISTRIBUTION: North and South America, Europe, Australia, New Zealand.

HABITAT: Effused on dead bark or decorticated wood.

Collections agree with part of the type collection of'Corticium' vagum examined in Kew herbarium. The species may be separated from P. scabrida by the narrower, smooth-walled repent hyphae and different type of branching; and from P. filamentosa by the differently shaped spores, and habitat.

TYPE LOCALITY: South Carolina, U.S.A.
