Description: 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.
Habitat: HABITAT: Effused on bark or decorticated wood of dead branches.
Distribution: DISTRIBUTION: Europe, North America, Japan, Australia, Tasmania, New Zealand.
Notes: 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.
