| Description： |
Pileus 3-4.5 cm broad, convex, surface siccous, fuscous olivaceous and minutely fuscous scurfy-squamulose. Context 3-4 mm thick, soft, pale yellowish white, color unchanging when bruised. Tubes 2-4 mm thick, adnato-decurrent, yellow then olivaceous. Pores 0.5-1 mm broad, circular to angular, somewhat in rows towards the margin, yellow, slightly cyanescent when bruised. Stipe 4-7.5 cm long, 4-7 mm broad, cylindric and tapered toward apex with whitish mycelium around base, color palely fuscous towards the base, dull red upwards to the yellow apex, surface appressedly whitish fibrillose except the apex. Spore print palely olivaceous. Spores 9.5-11.5 × 5.5-6 μm, ellipsoid. Basidia 36-42 × 13-14.5 μm, clavate, four sterigmata, 5-7 μm long. Pleurocystidia 35-43 × 6-12 μm, versiform, most are fusiform or subventricose with obtuse apex, not always conspicuous. Tube trama of phyl-loporoid type, the hyphae 8-10 μm wide. | |||

| Note： |
Contrary to our findings, Hoehnel gave the pores as being up to 2 mm wide. Besides unique characters like the fuscous scurfy-squamulose pileus and differently adorned stem, this species is found on rotten logs, well agreeing with Hoehnel and Singer. | |||
