Remarks (internal):There are several short-spored taxa in sect. Dysthales that can be distinguished from E. dysthaloides by having a not translucently striate pileus, non-encrusted stipe hairs and habitat in dry grasslands (E. hirtum), by having smaller, thin-walled, poorly angled spores (E. romagnesii); or more robust, paler fruitbodies with reddish stipe hairs and smaller, poorly angled, not nodulose spores (E. pulvereum). Entoloma pseudodysthales differs by having broader spores and the lack of cheilocystidia.

Pileus 3-15(-20) mm broad, conico-campanulate, then expanding to conico-convex, rarely plano-convex with small umbo, with straight margin, not hygrophanous, when moist translucently striate up to ha/f or three-quart of the radius, more rarelynot translucently striate, dark brown or fuligineous or blackish-brown, when young with radially orientated silvery fibrils, becoming (concentrically) fibrillose-squamulose all over with small, fibrilose, pointed, adpressed or slightly uplifted squamules. Lamellae, L = 15-25, l = 1-3, moderately crowded, adnate or emarginate, segmentiform to ventricose, brown to grey-brown, sometimes darker than pileus, with pink tinge with age, with fimbriate, concolorous edge. Stipe 15-60 x 0.5-2 mm, cylindrical or thread-like, concolorous with or slightly paler than pileus, longitudinally silvery striate, minutely flocculose-hairy with pale then brownish hairs, strigose at base with radiating, yellow to rusty-brown hairs, solid or fistulose. Context pale to dark brown, almost concolorous with surface. Smell indistinct. Taste indistinct.
Spores 10.5-13.5(-15.0) x 7.0-8.0(-8.5) µm, Q = 1.4-1.8, nodulose-angular with pronounced angles, relatively thick-walled, pale brown in water. Basidia 4-spored, clampless; abortive basidia with brown, intracellular pigment rare to frequent. Lamella edge sterile. Cheilocystidia 25-60 x 15-30 µm, subcylindrical to narrowly to broadly clavate, (sub-) globose, sometimes in chains, with thin- or slightly thick-walled, pale to dark brown, sometimes encrusted walls. Pilepellis a transition between a cutis and a trichoderm, made up of septate hairs, with elements 25-110 x 10-36 µm (base) x 7-11 µm (apex), gradually narrowing from base to apex. Stipitepellis a cutis of cylindrical, 4-10 µm wide hyphae, with scattered fascicles of up to 400 µm long, septate hairs. Pigment minutely to coarsely encrusting the walls of almost all hyphae in the fruitbody. Clamps absent inall tissues.
Habitat: terrestrial, often in groups on bare soil or in humus, in damp places in deciduous forest, often collected under or near Alnus and Fraxinus. June-Oct.
Distribution: Wide-spread in Europe and North America, not uncommon.
