Anamorph: not known. Teleomorph: Basidiomata agaricoid. Pileus 10–25 mm diam., hemispherical to conical or campanulate, sometimes with incurved margin, becoming plano-convex or remaining broadly conical, often umbonate, sometimes with irregular, lobed outline, margin faintly to strongly translucently striate to half-way, viscid or at least very lubricous, sometimes partially flared, at first usually pink-brown to orange-brown (brick, rusty tawny to fulvous), margin paler sometimes with orange (sienna to apricot) tints, hygrophanous, dried pilei dull orange (saffron to rust). Lamellae ventricose, mostly narrowly to broadly adnate with some slightly decurrent elements, intervenose, concolorous with pileus near pileal attachment, becoming paler towards free edge. Stipe 12–60 × 2–8 mm, cylindrical or compressed, sometimes with clavate base, hollow, sometimes flexuose, viscid but usually slightly less so than pileus, apically concolorous with pileus, paler below, sometimes basally tinted orange (apricot). Dried lamellar trama (lens) often darker than subhymenium and lamellar surfaces. Green pigments entirely absent. Without distinctive taste or smell. Lamellar trama subregular, compartments 20–120 × 4–21 μm. Clamp connections on basidia, within lamellar trama and pileipellis usually normal, occasionally with conspicuously looped hook cells (medallion clamps). Basidia predominantly 4-spored, clavate with attenuated base, (30–)34–57 × 5–9 μm excluding sterigmatal length (3.0–7.0 μm). Basidiospores (6.5–)7.0–9.0 × (4.0–)4.5–5.5(–6.0) μm, per-basidioma mean values 7.5–8.0 × 5.0 μm, Q = 1.3–1.8, mean 1.6, short-ellipsoidal to ellipsoidal, not constricted.
