Diagnosis fuente: Pileus: 10-35 mm, at first campanulate to conical-campanulate, later conicalconvex to plano-convex, as a rule umbonate, sometimes with somewhat uprolled margin, smooth, sometimes slightly radially rugulose, hygrophanous, striate to % radius and more, at first brown, rust-brown or light rust-brown to light brownish, later, beginning from margin becoming paler, to light greyish brown or brownish ochraceous, upon drying pale greyish orange, ochraceous, cream or almost whitish, with paler margin. Lamellae: narrowly adnate to almost free, moderately crowded to crowded yellowish brown to orange, brown, with pale finely flocculose edge. Stipe: 20-70 1-3 mm, cylindrical or slightly thickening towards clavate or nearly bulbous base (up to 5 mm wide), hollow, longitudinally pruinose-striate, at first whitish or cream, later darkening from base upwards to pale yellowish brownish, brownish, brownish orange or dark brownish. Context: in pileus up to 2 mm broad, whitish, in stipe whitish to dull brownish in stipe base. Taste and smell indistinct. Spore-print: light rust-brown. Spores: (8.0-)9.0-11.0(-12.0) x (4.5-)5.0-6.0(-6.5) um, Q=1.6-2.0; av.
Ls = 10.0£0.72 um, av. B =5.540.38 pm, av. Q=1.83+40.09; in face view ovateellipsoid, ellipsoid, in profile ellipsoid, slightly flattened ventrally to nearly in alkali light rust-brown. Basidia: 16.0-24.0 x 7.0-9.5 um, clavate, 4-spored. Cheilocystidia: 17.0-31.0 x 7.0-12.0 pm, lecythiform, neck up to 5.0 x 2.5 um, head 5.0—-6.5 um wide. Pleurocystidiabase:nt Pileocystidia: 24045.065-10.5 um, lecythiform, narrower than cheilocystidia, neck up to 15.0 x 2.5 um, head 3.5—6.5 um wide, scarce. Caulocystidia: mainly lecythiform, 15.5—38.0 x 7.0-18.0 um, neck up to7.0 x 2.5 um, head 4.0-7.5 um wide, with admixture of globose and clavate elements up to 17.0 x 12.0 um, at the top of stipe sometimes also present scattered hairs up to100.0 x 2.5—5.0 pm.
