Remarks (internal):Entoloma elodes takes a special position within subgenus Trichopilus because of the weakly hygrophanous pileus, that is glabrescent with age.
Entoloma elodes is a species typically confined to Sphagnum peat bog and peaty areas. Since its habitat rapidly disappears, especially in the lowlands of northwestern Europe, the species becomes increasingly rare.

Pileus 25-70 mm broad, conical then convex to applanate with low umbo or flat and/or slightly depressed at centre, with involute then deflexed margin, hygrophanous when moist not translucently striate or at margin only, dark grey-brown or reddish brown, sometimes with weak purple tinge, slightly pallescent on drying, adpressedly fibrillose or tomentose, often with subglabrous, micaceous patches in irregular patterns or subzonate, glabrescent with age. Lamellae, L = 25-60, l = 3-7, moderately crowded, adnate to emarginate, segmentiform to ventricose, white then pink finally reddish brown, with irregular, concolorous edge. Stipe 20-80 x 3-8 mm, cylindrical or compressed, sometimes broadened at base, pale brown, sometimes almost white or darker grey- or red-brown, always paler than pileus, pruinose at apex or not, downwards silvery striate often twisted, base white tomentose. Context rather brittle, paler than or concolorous with surface. Smell farinaceous, often fairly strongly so. Taste farinaceous-rancid.
Spores (8-)9-11.5(-12.5) x (6-)7-9(-9.5) µm, Q = 1.2-1.6, irregularly 5-8-angled in side-view. Basidia 4-spored, clamped. Lamella edge heterogeneous or sterile. Cheilocystidia 25-70 x 7-20(-25) (basal part) x 3-7 µm (neck), clavate to lageniform, more rarely lecithiform or tibiiform. Pileipellis a cutis of radially arranged, cylindrical to slightly inflated hyphae, sometimes with transitions to a trichoderm of semi-erect terminal elements, up to 20 µm wide. Pigment brown, intracellular in pileipellis. Clamps present.
Habitat: gregarious in peaty soil and in living Sphagnum in bogs or in very wet places in deciduous and coniferous forests; also in dryer heaths on peaty soil with Calluna, Empetrum etc. July-Nov.
Distribution: Wide-spread in northwestern and Central Europe, but becoming rare.
