Basidiome resupinate to somewhat reflexed, up to 1 mm thick, fairly tough when fresh. Hymenophore smooth, generally pale coloured to light brown. Hyphal system dimitic; skeletal hyphae 3-6 µm wide, thick-walled, hyaline, unbranched, straight to sinuous, without clamp-connections; other hyphae hyaline, smooth or sparsely incrusted, 2-4 µm wide, clamp-connections scattered and often difficult to find. Cystidia large, thick-walled, acute, strongly incrusted, embedded or commonly projecting above the basidia, 50-160 (200) x 12-25(-30) µm, hyaline to pale yellowish brown with age, arising from subhymenial hyphae or from skeletal hyphae, young cystidia sharply pointed and often smooth. Basidia clavate with a tapering base and with four sterigmata, 40-55 x 8-10 µm, with a basal clamp-connection. Spores cylindrical, smooth, thin-walled, variable in size, 10-16 x 6-7.5 µm.
