Hymenophore annual, membranous, adherent, effused forming linear areas 3-20 x 1-4 cm; hymenial surface cream, when old tinted ochre, isabelline, or pallid reddish-brown, finely velutinate, sometimes sparsely creviced when old; margin thinning out, white, fibrillose, adherent. Context white, 150-500 µm thick, basal layer narrow, of parallel hyphae, intermediate layer forming the bulk of the context, of loosely arranged hyphae becoming more dense and erect towards the surface; generative hyphae 6-8 µm diameter at the base, attenuated to 4-6 µm beneath the subhymenium, walls 1.5-2 µm thick, encrusted beneath the hymenium, branched at a wide angle, sometimes articulated at septa, without clamp connections, bridging hyphae common. Metuloids arising from the hymenial layer and subhymemum, the former projecting to 50 µm, cylindrical with rounded apices or as often fusiform and with acuminate apices, 60-85 x 8-10 µm, commonly with exposed surfaces finely encrusted, sometimes with tips only coated, or a few naked; embeddea metuloids narrowly fusiform, usually with acuminate apices, 45-72 x 12-20 µm, upper part coarsely encrusted. Hymenial layer to 40 µm, deep, a loose palisade of basidia, paraphyses, and metuloids. Basidia subclavate, 26-36 x 5-6 µm, bearing 4 spores; sterigmata slender, to 4 µm long. Paraphyses subclavate, 16-20 x 3-4 µm. Spores elliptical or suballantoid, 6-7.5 x 2.5-3 µm, walls smooth, hyaline, 0.25 µm thick.

DISTRIBUTION: Europe, North America, Japan, Australia, Tasmania, New Zealand.

HABITAT: Effused on bark or decorticated wood of dead branches.

P. cremea, P. filamentosa, and P. gigantea show certain relationships, for hyphae are of greater diameter than in other species described herein, are without clamp connections, and metuloids are of similar size and shape. P. cremea differs from P. filamentosa in that hyphae are encrusted with calcium crystals beneath the hymenium, possess thicker walls, branch at a wide angle, and margins are without rhizomorphs. In P. gigantea hyphae are naked.

TYPE LOCALITY: Tyrol, Austria.
