Remarks (internal):Entoloma strigosissimum is a very striking species with its long, thick-walled, setiform hairs on stipe and pileus. It has a very wide distribution, but seems to be rare. In the Netherlands E. strigosissimum occured with millions of specimens in the forests on clayey soil in the province of Flevoland from about 1980 on. This habitat, on land recently reclaimed from the sea, rich in sea-shells, there was a situation of relatively virgin soil-conditions, that were obviously very favourable far the species.

Pileus 4-30 mm broad, conical or conico-campanulate with slightly involute or straight margin, hardly expanding with age, not hygrophanous, not translucently striate, dark reddish brown or greyish brown, entirely covered with rather stiff reddish hairs, that sometimes agglutine in coarse, fibrillose scales. Lamellae, L = about 20, l = 0-1, rather distant, thickish, almost free or deeply emarginate, rather dark grey-brown then reddish brown with pruinose, concolorous or slightly paler or darker edge. Stipe 20-70 x 1-4 mm, cylindrical, often slightly to distinctly broadened towards base, dark brown or grey-brown, entirely covered with stiff red-brown hairs similar to those on pileus, base with ochraceous-reddish radiating hairs. Context concolorous with surface. Smell somewhat spermatical or none. Taste inconspicuous.
Spores (12.5-)14-19(-22) x 7-11 µm, Q = 1.5-2.3, strongly nodulose-multiangled in side­view, thick-walled, brownish in water. Basidia 4-spored, clampless, abortive basidia with brown content rather frequent. Lamella edge sterile. Cheilocystidia (25-)40-80 x 12-22 µm, slenderly to broadly clavate, obpyriform to subglobose, sometimes, especially near the margin of the pileus lageniform, with brownish walls, especially in the middle, sometimes also with brownish vacuolar pigment. Pileipellis a trichoderm with transitions to a hymeniderm at centre, made up of cylindrical to clavate terminal elements, up to 25 µm broad, mixed with very long, setiform hairs, up to 1000 x 10-20 (base) x 2-5 µ (apex), gradually tapering towards end, with reddish, thickened, non encrusted walls. Pigment coarsely encrusting in almost allparts of carpophore, in addition also parietal. Clamps absent.
Habitat: in grassland and in deciduous, coniferous or mixed forest, found on bare, clayey soil, in humus and on ratten wood, but also on slightly calcareous sandy soil in damp dune valley with Salix repens; summer-autumn.
Distribution: wide-spread, not very common, but in some localities very abundant in Europe and Northamerica.
