Remarks (public):The imbricate, ochraceous basidiocarps with irpicoid pores, and the bladder-like cystidia make the species easy to identify. For a discussion about the taxonomic position of the species, see Ryvarden (1992).

Basidiocarps annual, usually effused-reflexed and imbricate with several individual pilei arising from the same context, coriaceous when fresh, dense and cartilaginous when dry, pileus up to 1.5 cm wide or rarely wider, 1-2 cm long, but sometimes fused with adjacent pilei, margin sharp when fresh, usually strongly curved when drying; pilear surface first white to pale ochraceous, later pale buff, in old and hibernating specimens often darker from the base with dingy spots, glabrous, usually with radial lines or narrow folds or furrows; hymenophore first poroid, but soon irpicoid as the pores split, teeth flattened to round and pointed, 1-2 per mm, when young pruinose, later smooth, concolorous with the pilear surface; context dense, tough, whitish to pale ochraceous, up to 2 mm thick.
Hyphal system dimitic; generative hyphae with clamps, hyaline, thin-walled, 2.5-4 Jim wide; skeletal hyphae abundant, hyaline, unbranched, smooth, thick-walled, 37 µm wide, protruding in the dissepiments parallel to the tube walls, not projecting obliquely through the hymenium.
Cystidia present, but often difficult to find, smooth, thin-walled, tubular to bladderlike or ventricose with a swollen base and elongated neck, hyaline and negative with sulfobenzaldehyde, embedded in the hymenium or in the dissepiments, with a root up to 60 µm long, up to 181.1m wide.
Basidia clavate, 12-18 x 4-8 µm, with four sterigmata.
Basidiospores oblong-ellipsoid, (4.5)5-6 x (2.5)3-3.5 µm.
Substrata. On dead hardwoods.
Distribution. Known from New Zealand, Australia, South Argentina, in Asia known from India to Thailand, Vietnam, China (Jiangxi and Zhejiang), Far East Russia, and Japan (Kyushu and Honshu).
