UNKNOWN HOST. Queensland, Cooroy (herb. Kew).

Hymenophore annual, coriaceous, pileate, sessile. Pilei applanate, sometimes imbricate, 1-3 cm radius, 3-7 cm wide; pileus surface tobacco-brown, finely tomentose, concentrically zoned, plicate; pileus margin lobed, acute, plane; hymenial surface tobacco-brown, or umber, even, not creviced. Context ferruginous, to 500 µm thick, of compact parallel hyphae; cortex absent; abhymenial hairs closely arranged, slightly inflated at apices, brief; skeletal hyphae to 6 µm diameter, walls 0.5 µm thick, ferruginous; generative hyphae 3.5-4 µm diameter, walls 0.2 µm thick, hyaline or tinted yellow. Setal layer to 95 µm deep, composed of 3-5 rows of overlapping crowded setae; setae aculeate or fusiform, some projecting to 20 µm, 25-40 x 5-7 µm, walls naked, reddish-brown, 1-2 µm thick. Hymenial layer to 30 µm deep, a dense palisade of basidia and paraphyses. Basidia cylindrical, 12-18 x 4.5-5 µm, bearing 4 spores; sterigmata erect, to 4 µm long. Paraphyses cylindrical, 8-12 x 3-3.5 µm. Spores elliptical or suballantoid, 4-4.5 x 2.5-3 µm, walls smooth, hyaline, 0.1 µm thick.

DISTRIBUTION: India, South America, West Indies, Australia.

HABITAT: Bark of dead branches; type of rot not seen.

The collection listed has been compared with the type in Kew herbarium and found to agree in most features, differing in that surface hairs are more strongly developed. The species is pileate and, as it is without a cortex, belongs to Section II. It may be recognised by the small setae crowded in three to five overlapping rows, and short abhymenial hairs with slightly inflated apices arising directly from the context.

TYPE LOCALITY: Khasia Mountains, India.
