Pileus 1-3 mm diam, convex to broadly convex, disc depressed with an acute papilla; margin striate; surface dry, dull, glabrous to minutely pruinose; brownish orange (6C4-5) to light brown (7D5) overall with a brown to black papilla, drying tan to pale brown. Lamellae adnate to a collarium, distant (6-9), yellowish white (2A2) with light brown edges. Stipe 2-4 × 0.2 mm, central, cylindrical, filiform, dry, dull, glabrous, insititious, yellowish white at apex, brown at base; associated with brown, wiry, glabrous rhizomorphs but not arising from them.
Basidiospores 7.5-9 (-10) × 3-4 (-4.5) μm [xmr = 7.9-8.7 × 3.7-3.9 μm, xmm = 8.3 ± 0.6 × 3.8±0.1μm,Q=1.8-3,Qmr =1.6-3,Qmm = 2.2 ± 0.3, n = 26 spores per 2 specimens], ellipsoid, smooth, hyaline, inamyloid. Basidia 20-25 × 6 μm, clavate, 4-spored (few observed). Basidioles 19-25 × 5-7 μm, fusoid to clavate. Cheilocystidia numerous, composed of Siccus- type broom cells; main body 8-15 (-17) × (5-) 6-14 (-17) μm, clavate to broadly clavate or subcylindrical, rarely lobed, hyaline, inamyloid, thick-walled; apical setulae (2-) 3-5 × 0.5-1 μm, forked, cylindrical to conical, subacute to obtuse, seldom forked, yellow, inamyloid, thin- to thick-walled. Pleurocystidia absent. Pileipellis mottled, composed of a hymeniform layer of Siccus-type broom cells; main body (7-) 10-16 × (5-) 7-12 μm, clavate to subclavate or sometimes irregular in outline, rarely lobed, hyaline, inamyloid, thick-walled; apical setulae (3-) 4-8 × 0.5-1 μm, cylindrical to conical, subacute to obtuse, seldom forked, brownish yellow to dull yellow, inamyloid, thick-walled. Pileus trama interwoven; hyphae 3-4 μm diam, cylindrical, hyaline, inamyloid, thin-walled, non-gelatinous. Lamellar trama regular; hyphae 5-7 μm diam, cylindrical, hyaline, inamyloid to weakly dextrinoid, thin-walled, non-gelatinous. Stipe tissue monomitic; cortical hyphae 2-5 μm diam, parallel, cylindrical, smooth, yellow at apex, dull yellow at base, dextrinoid to strongly dextrinoid, thick-walled; medullary hyphae 3-4 μm diam, parallel, cylindrical, smooth, hyaline, inamyloid, thick- walled. Caulocystidia absent. Clamp connec- tions present.
