Description:Basidioma stipitate-pileate. Pileus tiny, 1.2 cm in diam., broadly convex, crimson (12C8) to dark red (11C8); surface rugose or somewhat areolate, usually cracking, viscid when wet and fibrillose to tomentose when dry; context white to cream, but red to reddish beneath pileipellis, without discoloration when injured. Hymenophore depressed around apex of stipe; hymenophoral surface white to pinkish (13A2); tubes concolorous with hymenophoral surface, color unchanging when injured; pores big, 1/mm; tubes short, up to 3 mm long, without discoloration when bruised. Stipe 2 × 0.2 cm, subcylindrical to clavate; surface red to dark red, but yellow (2A7–8) to yellowish (2A4–5) at apex and bright yellow to chrome yellow at base, covered with concolorous scabrous dotted-elements, without discoloration when touched; context yellowish to yellow, but bright yellow to chrome yellow at base, without discoloration when bruised; basal mycelium bright yellow to chrome yellow. Taste and odor mild.
Basidia 28–43 × 8–11 μm, clavate, 4-spored. Basidiospores (9) 9.5–11 (11.5) × 4.5–5.0 μm [Q = 2–2.3 (2.33), Qm = 2.13 ± 0.08], subfusiform in side view, narrowly oblong to subfusoid in ventral view, colorless to yellowish, smooth. Hymenophoral trama boletoid; hyphae cylindrical, 4.5–11 μm wide. Cheilo- and pleurocystidia absent. Caulocystidia clavate, lanceolate or subfusiform. Pileipellis a hypoepithelium: outer layer consisting of yellow to yellowish brown interwoven hyphae 2.5–6 μm in width with terminal cells 18–53 × 2.5–4.5 μm; inner layer made up of inflated subglobose cells (up to 16 μm in width) 3–4 in chains arising from radially arranged, repent filamentous hyphae 4–7 μm in width. Pileal trama composed of broad interwoven hyphae up to 15 μm in width. Clamp connections absent.
Habitat: Scattered on soil in tropical forest dominated by fagaceous plants (Lithocarpus spp. and Castanopsis spp.).
