Hymenophore annual, solitary, dimidiate, firm, somewhat brittle. Pileus applanate, to 7 cm. x 3.5 cm. x 20-25 mm. at the base; surface at first white, becoming pallid ochre, fawn, or dingy grey, covered with loose radiately arranged coarse strigose hairs which are finer towards the margin and of the same colour, in the centre compacted into coarse strigose erect tufts, cuticle wanting; margin bluntly acuminate, slightly inturned, lacerate, or strigose; hymenial surface white when fresh, drying dingy honey colour or pallid ochre, even, slightly concave or as often slightly convex, dissepiments toothed. Context white, to 15 mm. thick, of loosely woven hyphae arranged in parallel somewhat radiate bands; generative hyphae 4-6 µ thick, wall 1-1.5 µ, sparsely branched, septate, clamp connections large and abundant. Pores angular, less often rounded, 3-7 mm. deep, in section white, honey colour near orifices, separated from the context by a more densely woven layer to 0.5 mm. thick, 100-200 µ diameter, or 3-4 per mm.; dissepiments brittle, 50-100 µ thick, equal, apex even or finely velutinate. Basidial type clavate, basidia clavate, to 12 x 5 µ. Spores allantoid, 3.5-4.5 x 1-1.5 µ, smooth, hyaline.
New Zealand.
Growing solitary on decorticated decaying wood, usually on the under surfaces of logs.
Separated from P. atrostrigosus, which it resembles in other features, by the coarse, hyaline, usually radiately arranged strigose hairs, larger pores, and waxy brittle dissepiments.
Lloyd (1919, p. 823) recorded the species from Australia. His description shows that he had some other species before him, probably P. pelles Lloyd (syn. P. atrohispidus Lloyd) which has elliptical spores 6-7 x 4 µ, with an epispore tinted yellow. P. pelles in turn resembles P. spumeus Fr., differing mainly in the darker colour of the context. Both possess a monomitic hyphal system.
