Remarks (internal):Entoloma sericeoides is easily recognized on account of its depressed pileus. Microscopically it is very similar to E. sericeum, from which it mainly differs by the lack of clamps. Also the ecology is slightly different, as E. sericeoides prefers dry, (semi-)natural grasslands, and frequently appears in spring and early summer.

Holotypus: J. Lange, 12 July 1938, Sönderskov presso Kvaerndrup, Fyn, Danimarca (C).
Pileus 15-35(-60) mm broad, convex to plano-convex with depressed to umbilicate centre, with involute margin, marginal zone undulating and often somewhat grooved with age, hygrophanous, when moist sepia or chocolate brown, not very much paler towards margin, hardly translucently striate at margin, pallescent on drying along radial streaks, glabrous, smooth, subviscid when moist. Lamellae, L = 30-45, l = 1-3, fairly crowded or more or less distant, adnate, often with decurrent tooth or slightly emarginate, segmentiform to narrowly ventricose, grey or brown then with pink tinge, with serrulate, concolorous edge. Stipe 20-40 x 2-6 mm, cylindrical, often with swollen base, concolorous or paler than pileus, strongly longitudinally fibrillose-striate, sometimes twisted, base white tomentose. Context in pileus and stipe-cortex brownish, pallid in inner parts, brittle. Smell spontaneously weak, grassy­-subspermatical, distinctly farinaceous when bruised. Taste farinaceous-rancid.
Spores 7.0-9.0 x 6.0-8.0 µm, Q= 1.0-1.2, (sub-) isodiametrical, 5-6-angled in side-view. Basidia 4-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis a cutis of narrow, 2-7 µm wide, cylindrical hyphae. Pigment encrusting in pileipellis and pileitrama. Clamp-connections absent.
Habitat: in relatively dry, sunny spots, preferably on calcareous or neutral, not acid soil often in association with Rosaceae (Prunus, Crataegus), and in xerophytic grasslands, on dykes and in dune-grasslands on calcareous sandy soil; late spring (may-june) and autumn. Distribution: Wide-spread but rare in northwestern and central Europe.
