MycoBank Number: 823307
Description:— Basidiomata medium to large. Pileus 3–11 cm broad, subglobose-hemispherical at first, then applanate, finally slightly depressed, margin enrolled, sometimes faintly wavy-lobed at maturity, smooth or minutely scaly, dry, pale yellow-orange to pale orange-yellow in color, cream-brown (5C3) to brown (5C3) at the centre. Lamellae crowded, 2–3 lamellulae tiers between each pair of entire lamellae, short-decurrent, thin, 1–2 mm broad, dirty white to pale brown. Stipe 0.7–2.3 cm in diam, 3.0– 8.5 cm in length, central, cylindro-clavate, somewhat broadened towards the base, usually flexuous, fleshy, solid to loose, with rhizomorphs, longitudinally striped, concolorous with the pileus. Context 2–4 mm thick, thinner at the margin, white. Odour faint, not distinct.
Spores (4.0–)4.5–5.5 (–6.0) × (2.5–) 3.0–3.7 μm, Q = 1.33–1.64 (Qm = 1.47), ellipsoid to amygdaliform, surface coarse under the SEM, slightly amyloid, not cyanophilous, not collapsing and not adhering in tetrads. Basidia 16.5–32.5 × 4.0–6.0 μm, 4-spored, cylindro-clavate, with sterigmata 5 μm long, without carminophilic/siderophilous granulation. Cystidia absent. Hymenophoral trama regular, made up of cylindrical to inflated hyphae, 5–16 μm diam. Pileipellis a cutis of radially arranged, inflated hyphae, 5–12 μm diam, with intracellular yellow pigment. Stipitipellis composed of repent cylindrical hyphae, 4–10 μm diam. Clamp connections absent in all parts of the basidioma.
Habitat and distribution:—Solitary, on soil with rich humus, in montane coniferous forests, known from temperate zones of southwestern China; found during summer.
