Hymenophore annual, adherent, fragile, membranous, effused forming irregular areas 3-15 x 1-5 cm, 1-1.5 mm thick, with numerous outlying islands. Hymenial surface isabelline or alutaceous, even, slightly glancing; margin cream, fibrillose, to 3 mm wide, irregular, thinning out, adherent. Pores not in strata, 5-7 per mm, 100-200 µm diameter, to 1.5 mm deep, round or angular, sometimes oblique when linear; dissepiments 50-100 µm thick, equal, even or delicately velutinate. Context cream, 0.2-0.4 mm thick, of densely intertwined hyphae embedding abundant crystals; generative hyphae hyaline, 3-3.5 µm diameter, branched, septate, with clamp connections, walls 0.2 µm thick. Hymenial layer to 20 µm deep, a compact palisade of basidia and paraphyses. Basidia clavate, 6-8 x 4-5 µm bearing 4 spores; sterigmata arcuate, slender, to 4 µm long. Paraphyses subclavate, 4-6 x 3-4 µm Spores obovate or pip-shaped, 5-5.5 x 3-3.5 µm walls smooth, hyaline, 0.1 µm thick.

DISTRIBUTION: Australia, New Zealand.

HABITAT: Bark of fallen branches, associated with a white rot.

Collections agree with the type, differing slightly in surface colour. The species resembles P. mollusca and P. curreyana in the minute pores and obovate or pip-shaped spores. It differs from the former in colour of the hymenial surface and arrangement of context hyphae; and from the latter by the different surface colour, absence of pigment granules, narrow diameter of generative hyphae, and larger spores.

TYPE LOCALITY: Swan River, Western Australia.
