Hymenophore annual, adherent, membranous, effused forming linear areas 5-22 x 1-4 cm; 1-2 mm thick. Hymenial surface at first snow white, glancing, drying white or pallid cream, even, not creviced; margin thinning out, white, fibrillose, to 5 mm wide, adherent. Pores not in strata, angular, when old a few in the central area becoming elongated, 3-6 per mm, 100-200 µm diameter, to 2 mm deep; dissepiments entire, equal, 50-110 µm thick, apices tufted with delicate hyphae. Context white, 50-200 µm thick, floccose, of closely intertwined hyphae embedding scattered crystals; skeletal hyphae 2.5-3 µm diameter, walls 0.5-1 µm thick, sparsely branched, aseptate; generative hyphae 1.5-2 µm diameter, walls 0.2 µm thick, branched, septate, with clamp connections. Hymenial layer to 15 I µm deep, a close palisade of basidia, paraphyses, and paraphysate hyphae. Basidia clavate or subclavate, 8-12 x 3.5-4 µm, bearing 4 spores; sterigmata erect, slender, to 4 µm long. Paraphyses subclavate, 6-10 x 3-3.5 µm. Paraphysate hyphae capitate, apices to 5 µm diameter, projecting to 20 µm, scattered or crowded in dissepiments and especially near apices, some crystal encrusted. Spores allantoid, many lunate, 2.5-4 x 1-1.5 µm, walls smooth, hyaline, 0.1 µm thick.

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

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

Collections agree with the excellent description and figure published by Eriksson (1949, p. 11). The species may be separated from related soft white ones by the allantoid, often lunate small spores, dimitic hyphal system and moderately small pores with thin dissepiments and presence of occasional capitate paraphysate hyphae sometimes bearing crystals. The type collection of Poria minutipora was found to be of this species, with similar lunate spores, minute pores, and skeletal hyphae.

TYPE LOCALITY: Finland.
