Remarks (internal):Entoloma hirtum is very rare in the Netherlands, and has been found only once. The description is based on a Netherlands' collection and supplemented by notes on Danish material (see Noordeloos in Persoonia 10: 224. 1979). Entoloma hirtum differs from E. dysthaloides mainly in the type of stipe-covering and the pigmentation of hairs on the stipe, and possibly also in the habitat. Entoloma pulvereum: is much larger, and has smaller, less angular spores.

Sel. descr. & figs. - Noordel. in Persoonia 10: 223-225, figs. 21-26. 1979.
Pileus 4-20 mm, conical, sometimes truncate, usually blunt or with indistinct papilla, rarely with slight central depression, with involute, then straight, sometimes crenulate margin, not hygrophanous, not or faintly translucently striate at margin, ash grey with blackish centre, sometimes with brown tinge, entirely fibrillose-squamulose with triangular squamules, which are erect at centre, adpressed towards margin, dull. Lamellae, L = about 25, I = 1-3, moderately distant, adnate-emarginate, sometimes with slight decurrent tooth, often deeply emarginate to almost free, ventricose, dark grey-brown with pinkish tinge, with subentire or flocculose, concolorous or slightly paler edge. Stipe 30-70 x 1-3 mm, cylindrical or slightly tapering downwards, solid, then narrowly fistulose, concolorous with pileus or slightly paler, with pale to brownish, arachnoid covering, glabrescent, strigose at base with yellow-brown radiating hairs. Context membranaceous, concolorous with surface, in thick-fleshed specimens paler in inner parts. Smell none. Taste none or bitter.
Spores (10.0-)l1.0-15.0 (-15.5)x 7.0-8.0 (-9.0) µm, Q = 1.3-1.8. Qav = 1.55, 6-8-angled in side-view, with pronounced angles. Basidia 34-46 x 10-15 (-20) µm 4-spored, clampless. Lamella edge sterile or heterogeneous. Cheilocystidia 20-60(-75) x (9-)12-35 µm, narrowly to broadly clavate with rounded or conical apex. rarely subglobose or subcylindrical. with thin or slightly thickened, hyaline or brownish, often incrusted walls. Pileipellis a cutis with transitions to a trichoderm, made up of repent to ascending, multiseptate, attenuated hairs. with elements 46-110 µm long, 11-20 µm wide at base, and 4-7 µm wide at apex. Stipitipellis a cutis with scattered 0-2 septate, yellow-brown, not incrusted hairs up to 170 um long, up to 16 µm wide. Pigment slightly to coarsely incrusting the hyphae of pileipellis, pileitrama, stipititrama and hymenophoral trama. Clamp-connections absent from all tissues.
Habitat & distr. - Solitary or in small groups, terrestrial in xerophytic grassland on calcareous loamy soils in shade of Prunus spinosa, Juniperus communis, etc. Very rare (Gronsveld: Savelsbos). Widespread in Europe hut rare. June-Sept.
