Basidiocarps perennial, resupinate, becoming widely effused, woody, not readily separable; margin at first yellowish brown, tomentose, up to 2 cm thick, receding, becoming black and rimose in older specimens; pore surface yellowish- to grayish brown, dull, smooth, the pores circular, 6-8 per mm, the dissepiments thick, entire, minutely tomentose; Contextual hyphae dark brown in KOH, thin- to thick-walled, rarely branched, occasionally septate, 2.5-5 µm in diam, some almost hyaline, thinner walled; tramal hyphae similar.
Setae lacking; thin-walled, ventricose cystidioid elements present. Basidia broadly clavate, 4-sterigmate, 11-12.5 x 7-8.5 µm.
Basidiospores broadly ovoid to subglobose, hyaline, smooth, strongly dextrinoid in Melzer's reagent, 6.5-8.5 x 5.5-7 µm.
Type of rot - Uniform white rot of dead wood of hardwoods and conifers. Cultural characteristics - See Nobles (1948, 1958, 1965).
