Description: Hymenophore biennial, probably perennial, adherent, firm, woody, effused forming irregular areas 6-14 x 5-10 cm, 2-10 mm thick. Hymenial surface irregular, nodose or crenulate, light or dark umber, when young fulvous, slightly glancing; margin thinning out, layers receding, to 2 mm wide, at first tan becoming black, thick and crenate, adherent. Pores in one or two layers, 5-6 per mm, 75-125 µm diameter, 1-5 mm deep in each layer; dissepiments 25-100 µm thick, equal, even. Context fulvous, 0.2-0.5 mm thick, of compact intertwined hyphae embedding crystals; skeletal hyphae to 4.5 µm diameter, walls 1 µm thick, yellow-brown, septate, sparsely branched; generative hyphae to 3 µm diameter, walls 0.2 µm, thick, hyaline, septate, branched. Hymenial layer to 15 µm deep, a dense palisade of setae, basidia and paraphyses. Setae ventricose, bases inflated, apices acuminate, 12-16 x 4-6 µm walls chestnut, abundant. Basidia oblong, 6-8 x 3.5-4 µm, collapsing, bearing 4 spores; sterigmata erect, slender, to 3 µm long. Paraphyses oblong or obovate, 5-6.5 x 3-3.5 µm. Spores oval, broadly oblong, subglobose or globose, 5-6 x 4-5 µm, walls smooth, yellow brown, 0.2 µm thick.
Habitat: Bark of fallen trunks, associated with a white rot.
Distribution: New Zealand.
Notes: Separated from the other species present in the region possessing coloured spores, by the abundant small ventricose setae, pores with thin dissepiments, and fulvous context with freely septate skeletal hyphae. This last condition is unusual in species of the genus.

Notes: The species is characterised by strongly coloured spores, and it is restricted to Nothofagus.
