Pileus dimidiate, up to 50 cm wide, upper surface blackish brown or grayish brown, non-laccate, distinctly concentrically ridged and zonate margin obtuse. Context uniformly ochraceous or cinnamon, firm. Tubes brown to deep brown, stratified, 5-7 mm thick each layer. Pore surface brown or yellowish brown, sometimes yellow; pores suborbicular, 4-5 per mm. Pilear crust hard, similar to subanamixoderm, composed of hyaline, thin-walled generative hyphae and thick-walled brown skeletal hyphae agglutinated together. Hyphal system trimitic; generative hyphae hyaline, thin-walled, branched, septate, 3-6 µm diam; skeletal hyphae brownish to brown, thick-walled to solid, arboriform or aciculiform; skeletal stalks 3-5 µm diam, with branches ending in flagelliform binding processes; binding hyphae colorless to faintly yellowish borwn, thick-walled branches, 1-2 µm diam. Basidiospores 9-13.5 × 6-10.5(-12) µm, ovoid, broadly ellipsoid or truncate at apex, bitunicate; exospore hyaline, smooth, endospore distinctly echinulate, brownish to brown.
