Remarks (internal):Entoloma flocculosum differs from the closely related taxa E. phaeocyathus and E. rusticoides mainly in the densely flocculose to squamulose pileal surface. In addition it differs from E. phaeocyathus by the absence of cheilocystidia, and E. rusticoides has more distinctly decurrent lamellae.

Pileus 8-15 mm broad, hemispherical then convex, with distinctly depressed centre, with deflexed, regular or slightly undulating margin, weakly hygrophanous, when moist very dark reddish brown to blackish brown, not translucently striate, pallescent along radial streaks from centre on drying to medium brown, entirely finely floccose to squamulose with pointed squamules with a pallid uplifted tip. Lamellae, L = 12-15, l = 1 (-3), moderately distant, broadly adnate, usually with small decurrent tooth, dark brown concolorous pileus then with pink tinge, with entire, concolorous edge. Stipe 6-15 x 0.5-2 mm, cylindrical or with attenuate base, concolorous with pileus, slightly paler at apex, smooth, almost glabrous or with scattered whitish fibrils. Smell none. Taste unknown.
Spores 8.0-11.0 x 7.0-9.5 µm, Q = 1.0-1.2, isodiametrical, 6-8-angled in side-view. Basidia 4-, rarely also 2-spored, clampless. Lamella edge fertile. Cystidia absent. Pileipellis a cutis with transitions to a trichoderm, made up of repent to ascending, cylindrical hyphae, up to 20 µm wide with more or less clavate terminal elements, 30-70 x 15-25 µm. Pigment dark brown, strongly encrusting the hyphae of pileipellis and upper pileitrama, and in addition also intracellular. Clamps absent.
Habitat: in short-grazed grassland and in xerophytic grassy vegetation, preterably on calcareous soils; also recorded from burnt ground; Aug.-Oct.
Distribution: Wide-spread but rare in Central Europe and northern Italy.
