Remarks (internal):The distinctive characters of E. dysthaloides are the flocculose stipe with multiseptate, incrusted hairs and the small spores. Entoloma dysthales has much larger spores, and E. hirtum has non-incrusted, differently shaped hairs on the stipe, and another ecology. Entoloma romagnesii has smaller, less nodulose spores (see Noordeloos in Persoonia 10: 225. 1979).

Description:Entoloma dysthaloides Noordel. in Persoonia 10: 219. 1979. - Fig. 83.
Misappl. - Nolanea dysthales sensu Nath.-W. in Acta I lorti Gotoburg. 16: 142. 1946; Rhodophyllus dysthales sensu O. v. Schulmann in Karstenia 5: 31. 1960.
Sel. descr. & figs. - Mos. in Persoonia 7: 286-287, figs. 1a, 2c, 3c-2. 1973 (as Rhodophyllus spec.); Noordel. in Persoonia 10: 222-223, figs. 13-20. 1979.
Pileus 3-15 (-20) mm, conico-campanulate, then expanding to conico-convex, rarely plano-convex with small umbo, with straight margin, not hygrophanous, when moist translucently striate up to half or three-quarters of radius or not striate, dark brown or fuligineous (at centre Mu. 5 YR 2.5/2, at margin 10 YR 4/3), when young with radially arranged silvery white or brownish fibrils, becoming concentrically squamulose with minute, pointed squamules with brownish tips. Lamellae, L = 15-24, I = 1 (-3), moderately crowded, adnate or emarginate, narrowly to broadly ventricose, brown to grey-brown, sometimes darker than pileus (e.g. 7.5 YR 4/2), with pink tinge, with slightly eroded, concolorous edge. Stipe 15-60 x 0.5-2 mm, cylindrical or filiform, sometimes flexuose, concolorous with or slightly paler than pileus (e.g. 7.5 YR 4/2), longitudinally silvery striate, minutely flocculose with pale, then brownish hairs, strigose at base with radiating, yellow to rusty brown hairs, solid or fistulose. Context pale to dark brown, sometimes with grey tinge, membranaceous in pileus, firm in stipe of large specimens. Smell indistinct. Taste indistinct.
Spores 10.5-13.5 (-15.0) x 7.0-8.0 (-8.5) µm, Q = 1.4-1.8, Qav = 1.6, nodulose-angular with pronounced angles and pale brown walls. Basidia 40-54 x 14-19 µm, 4-spored, clampless. Lamella edge sterile, rarely heterogeneous. Cheilocystidia 26-60 x 15-28 µm, narrowly to broadly clavate, subcylindrical to obovate with rounded or attenuated, conical apex, frequently with brown-coloured or incrusted wall. Pileipellis a cutis with transitions to a trichoderm, made up of radially arranged, repent or ascending, multiseptate hairs that are gradually tapering towards the terminal elements, 25-110 µm long, 10-36 µmwide at base., 7-11 µm wide at apex. Stipitipellis a cutis of 4.5-10 µm wide hyphae with scattered fascicules of up to 400 µm long, multiseptate hairs, similar to those on pileus. Pigment coarsely incrusting the hyphae of pileipellis, stipitipellis and trama of pileus, stipe, and lamellae. Clamp-connections absent from all tissues.
Habitat & distr. - Terrestrial, often in groups in moist, shadow rich places, particularly in swamp forests of Alnus. Not uncommon. Wide-spread in Europe. June-Sept.
