Pileus 3–4.5 cm in diameter, subhemispherical to applanate; surface dry, smooth, gray (5 B 1) to brownish gray (5 B 2), staining reddish brown when bruised; margin slightly extended; context whitish (1 A 2) to pallid (1 A 3), changing to reddish (8 B 4) or brownish red (8 C 4) quickly, and then slowly becoming blackish (19 F 5) when injured. Hymenophore adnate to slightly decurrent, or sometimes slightly depressed around apex of stipe when mature; surface initially whitish (1 A 2) to cream (1 A 3) or dirty white to grayish (4 B 1); pores angular to roundish, up to 1 mm wide, tubes up to 6 mm long, concolorous or a little paler than hymenophoral surface, changing to reddish brown (8 C 3) at first and then becoming blackish when injured. Stipe 5–8.3 × 1–4 cm, clavate to subcylindrical, flexuous, solid, grayish (5 C 3) to blackish brown (5 E 2), dark in color downwards, staining reddish brown at first and then blackish when bruising; context white (1 A 1) to cream (1 A 2), changing to brownish red (8 C 4) quickly, then slowly becoming blackish (19 F 5) when injured; basal mycelium white (1 A 1).

Hymenophoral trama boletoid; hyphae cylindrical, 4–10 μm wide, hyaline to yellowish in KOH, yellow to yellowish brown in Melzer’s reagent. Cheilocystidia 34–55 × 8–14 μm, fusiform or subfusiform, thin-walled, hyaline to brownish in KOH, yellowish brown to brownish in Melzer’s reagent; surface without encrustations. Pleurocystidia morphologically similar to cheilocystidia.
