FAGACEAE. Nothofagus fusca: Wellington, Gollans Valley, 120 m. MELIACEAE. Dysoxylum spectabile: Auckland, Whitianga. Coromandel Road, 70 m. IN KEW HERBARIUM: Only one collection from the region, ex "Q., Toowoomba", filed under Poria blepharistoma.

Hymenophore annual, at first adherent, becoming loosely attached, membranous, brittle, effused forming irregularly linear areas 5-18 x 2-4 cm, with a few elliptical outlying islands. Hymenial surface white, drying cream, pallid alutaceous or wood colour, even, sometimes irregularly creviced; margin thinning out, fibrillose, white, 1-5 mm across, sometimes with brief rhizomorphs. Pores at first 2-3 per mm, often splitting when old when 1-3 mm long, 1-3 mm deep; dissepiments equal, 75-120 µm thick, apices even or toothed. Context 50-150 µm thick, white, of closely intertwined hyphae; generative hyphae 2-3.5 µm diameter, walls 0.2 µm thick, sparsely branched, septate, with clamp connections. Hymenial layer to 20 µm deep, a close palisade of basidia and paraphyses. Basidia subclavate, 8-15 x 3-4 µm, bearing 2-4 spores; sterigmata erect, slender, to 3 µm long. Paraphyses subclavate, many cylindrical, 6-14 x 3-3.5 µm. Spores obovate, oval, many cylindrical, abundant, 3-4.5 x 3-3.5 µm, walls smooth, hyaline, 0.1 µm thick.

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

HABITAT: Decorticated wood of fallen branches and trunks, associated with a white rot.

Characters of the species are the large and (when old) irregular pores, fragile context, monomitic hyphal system with clamp connections on the generative hyphae, and minute, abundant, obovate or oval spores. In surface features the species resembles P. vaporaria but the latter differs in its dimitic hyphal system and allantoid spores. No authentic collection of P. vaporaria from the region has been seen.

TYPE LOCALITY: Europe.
