Original description
Basidiocarps single. Pileus 30-50 mm broad, applanate with plane to slightly depressed centre and straight margin, hygrophanous, translucently striate, smooth at centre, slightly sulcate up to 2/3, glabrous, lustrous when moist and then very slightly sticky, reddish ochre-brown (6-7C5) at centre, slightly paler towards margin. Lamellae moderately close, L = c. 30, l = 2-3, emarginate and attached with tooth, slightly nodulose at base, yellowish white to orange-white (± 4-5A2) with concolorous, ± smooth edge. Stipe up to 110 × 3 mm, cylindrical, slightly broadened at apex, bulbose-clavate (8 mm) at base, non-insititious, fistulose, slightly striate at apex (descending lamellae teeth), slightly fibrillose otherwise, slightly fibrillose-tomentose (apex), concolorous with lamellae at apex, light brown (± 6D5) otherwise; with rich whitish basal tomentum. Context concolorous with pileus surface (in pileus) and stipe (in stipe) surface colour, hollow in stipe, without any special smell.
Basidiospores (8.0-)8.5-10 × 3.5-4.0 µm, average = 8.9 × 3.7 µm, E = 2.1-2.8, Q = 2.4, fusoid, navicular, subcylindrical, smooth, thin-walled, hyaline; slightly thick-walled spores also present. Basidia 25-28 × 6.5-7.5 µm, 4-spored, clavate. Basidioles 15-30 × 3.0-7.0 µm, cylindrical, clavate or subfusoid. Cheilocystidia 12-23 × 5.0-12 µm, variable in shape, clavate, fusoid, subcylindrical, often irregular, lobate to subcoralloid, thin-walled. Pleurocystidia 43-77 × 6.0-13 µm, fusoid, sometimes pedicellate, often pimpled, thin-walled, refractive. Trama hyphae formed by cylindrical or fusoid, thin- to slightly thick-walled, often minutely incrusted, hyaline, up to 25 µm wide cells. Pileipellis a hymeniderm composed of cells 20-29 × 12-18 µm, clavate or pyriform, thin- to slightly thick-walled, smooth, pale yellowish in KOH. Stipitipellis a cutis of cylindrical, parallel, slightly thick-walled, smooth, up to 8.0 µm wide hyphae. Caulocystidia absent; scattered (sub)erect, ± cylindrical, obtuse, thin-walled terminal cells present. Clamp connections present in all tissues.
