IN KEW HERBARIUM: Only the type collection, ex "N.Z., Dannevirke, Colenso, b 522".

Hymenophore annual, solitary, hard and woody, laterally attached by a broad base, sometimes dimidiate and imbricate. Pilei triquetous or flabelliform, 2-4 cm wide, 1.5-2.5 cm radius, 5-8 mm thick; pileus surface dingy grey or black, densely clothed with coarse imbricated strigose tufts of hyphae radiately arranged, with walls fuscous and bearing granules of mucilage, obscurely sulcate; without a cortex; margin bluntly acuminate, lacerate, inturned; hymenial surface wood colour or smoky brown, irregular. Pores irregular, wood colour in section, angular, 4-6 per mm, 100-200 µm. diameter, to 5 mm deep; dissepiments 50-150 µm thick, tapering, apices strongly toothed. Context white or cream, 2-5 mm thick, firm and woody, of parallel hyphae radiately arranged and aggregated at intervals into compact bands; generative hyphae 5-7 µm diameter, 3-4 µm in dissepiments, walls 0.5-1.5 µm thick, sparsely branched, septate, with clamp connections. Hymenial layer to 18 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 10-12 x 3.5-4 µm, bearing 2-4 spores; sterigmata erect, slender, to 3 µm long. Paraphyses subclavate or subcylindrical, 6-10 x 3-3.5 µm. Spores allantoid, 4-5.5 x 1.5-2 µm, walls smooth, hyaline, 0.1 µm thick.
New Zealand, Tasmania.
Solitary or occasionally imbricate on bark or decorticated dead branches and trunks, associated with a brown cubical rot.
Specific features are the coarsely imbricated strigose black hairs clothing the pileus surface, small pores, and allantoid spores. The species is close to T. setiger, differing mainly in the smaller pores and different type of surface hairs. Lloyd (1922b, µm. 1147) recorded the species from Tasmania, but as he described spores as being elliptical, 6 x 5 µm, it is probable he had at hand a specimen of T. pelliculosus, which it resembles in surface features.
LOCALITY: Dannevirke, Hawke's Bay.
