Description: Hymenophore annual, adherent, membranous, effused forming linear areas 6-10 x 2-3 cm, 1-3 mm thick. Hymenial surface white, pallid cream, or wood colour, irregular, appearing irpiciform, not creviced; margin thinning out, a delicate white zone 2-5 mm wide when young, sometimes fertile to the edge, fibrillose, irregular, sometimes with white rhizomorphs. Pores not in strata, irregular in size and shape, often oblique, 1-2 per mm in young plants, 0.5-1.5 mm diameter in old, to 0.8 mm deep; dissepiments 50-150 µm thick, tapering, toothed. Context white, 50-200 µm thick, of intertwined hyphae embedding crystals; generative hyphae 3.5-4 µm diameter, walls 0.25 µm thick, branched, septate, without clamp connections. Hymenial layer to 30 µm deep, a close palisade of basidia and paraphyses. Basidia subclavate, 14-22 x 4-7 µm, bearing 4 spores; sterigmata erect, to 4 µm long. Paraphyses subclavate, 10-16 x 4-5 µm. Spores narrowly elliptical, or obliquely apiculate, 5-7 x 3-4 µm, walls smooth, hyaline, 0.1 µm thick.

Habitat: HABITAT: Decorticated fallen trunks, branches and worked timber, associated with a white rot.

Distribution: DISTRIBUTION: Europe, North America, Australia, New Zealand.

Notes: Specific features are the monomitic hyphal system without clamp connections on the generative hyphae, large-diameter, often irpiciform pores, and elliptical spores. Plants resemble closely in macrofeatures collections of P. vaporaria from Sweden. The latter differs in its dimitic hyphal system, presence of clamp connections on the generative hyphae, and allantoid spores 4 x 1.5 µm. Specimens agree with European collections of the species in Kew herbarium, differing mainly in that rhizomorphs are not so well developed and in one collection are wanting. Australian records of the presence of P. vaporaria were based on specimens of P. versipora, judged from collections examined in Kew herbarium. The former has not been found in this botanical region.
