Description: 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.
Habitat: HABITAT: Effused on dead bark or decorticated wood.
Distribution: DISTRIBUTION: North and South America, Europe, Australia, New Zealand.
Notes: 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.
