Page number:343 
Remarks (internal):Entoloma dysthales has such dark, brownish-grey lamellae that is sometimes has been mistaken for a small Inocybe species, also referring to the fibrillose-squamulose pileus. Because of its small size and dark fruitbodies, growing in damp, often dark situation on the forest floor, it is easily overlooked. Entoloma dysthaloides, that grows in similar habitats, differs mainly by its much smaller spores.

Pileus (2-)5-20 mm broad, conico-campanulate or hemispherical, expanding to conico-convex, convex rarely plano-convex, then often with small papilla, with deflexed then straight or finally slightly reflexed margin, with undulating marginal zone with age, weakly hygrophanous, when moist blackish-grey or sepia brown, only slightly paler at margin, translucently striate up to half the radius, slightly pallescent on drying to grey-brown, centra remaining darker, when young with silvery-hyaline hairs that turn brown with age, often united in small pointed, adpressed or reflexed squamules, at margin fringed and sometimes rimose, sometimes entirely minutely squamulose. Lamellae, L = 1-=20, l = 1-3, moderately distant to fairly crowded, narrowly adnate or emarginate, narrowly segmentiform to distinctly ventricose, sometimes transvenose, dark grey to grey-brown, finally with pink tinge, with flocculose, concolorous or slightly paler edge. Stipe 10-50 x 0.3-2 mm, cylindrical, often slightly broadened at base, concolorous with pileus, silvery striate, entirely sparsely to densely hairy, flocculose or subsquamulose with pale to dark brown hairs, base strigose with long, radiating, pale yellow-brown hairs, solid or narrowly fistulose. Context thin, concolorous with surface. Smell indistinct. Taste mild.
Spores 13.5-19.5(-21.5) x (7.5-)8.0-10.5(-11.0) µm, Q = 1.5-2.1, heterodiametrical, more or less ellipsoid in outline with many angles, appearing nodulose in all views, relatively thick­walled, brownish in water. Basidia 4-spored, clampless; abortive basidia rare to abundant, with brown, intracellular pigment. Lamella edge sterile. Cheilocystidia 15-90 x 8-25 µm, narrowly to broadly clavate, (sub-) globose, obpyriform, sometimes in chains, rarely with finger-like apical appendages, 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 30-200 x 10-25 µm (base) x 9-12 µm (apex), gradually narrowing from base to apex. Stipitepellis a cutis of cylindrical, 4-17 µm wide hyphae, entirely beset with septate hairs, short, 1-2-septate at apex, and longer, up to 5 septate towards base, elements 20-55 µm.long, up to 30 µm wide in basal part of hairs, gradually tapering towards apex, 5-12 µm wide. Pigment minutely to coarsely encrusting the walls of almost all hyphae in the fruitbody. Clamps absent in all tissues.
Habitat: terrestrial, often in groups on base soilor humus, in damp situations in deciduous forest, frequently collected under Alnus and Fraxinus, but also in ditch in coniferous forest, once in damp Salix repens vegetation. July-Nov.
Distribution: Wide-spread in Europe and North America, not uncommon.
