Remarks (internal):Entoloma turbidum can be distinguished from E. vinaceum particularly in the more robust, tricholomatoid habit and dark colour of the pileus. Noordeloos (1981) distinguished a variety from grasslands with thick, distant lamellae as var. pachylamellatum Noordel. This variety has only been collected on the type-locality in the Netherlands.

Pileus 15-70 mm broad, truncate-conical, campanulate or hemispherical then expanding to convex or plano-convex, with low, broad umbo, with inflexed then deflexed or straight margin, hygrophanous, when moist obscurely to distinctly translucently striate at margin up to half the radius, grey-brown or sepia, sometimes more or less reddish brown, paler towards margin, pallescent on drying, smooth, glabrous or subtomentose at centre when dry. Lamellae, L = 30-45, l = 1-7, fairly crowded, deeply emarginate, almost free or adnexed, ventricose, greyish, rarely almost white when young then pink, frequently with grey tinge, with eroded, concolorous edge. Stipe 25-90 (110) x 3-12 mm, cylindrical or flexuose, usually distinctly tapering towards base, pale grey-brown, especially in the middle, apex often paler base frequently with yellow tinge, particularly when bruised, fibrillose-striate, narrowly fistulo­se. Context concolorous with pileus in cortex, inner parts pale, in base of stipe often tinged yellow. Smell none, rarely somewhat farinaceous. Taste mild to distinctly rancid.
Spores 6.5-8.5(-9.0) x 6.0-7.0(-7.5) µm, Q= 1.0-1.2, very thin-walled and many-angled with weak angles, appearing almost nodulose, cyanophilous. Basidia 4-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis an ixocutis of 2.5-5 µm wide, cylindrical hyphae. Pigment brown, intracellular in pileipellis. Clamps present in all tissues.
Habitat: in or near coniferous forest, also in heaths of Calluna, Erica or Empetrum, usually on peaty or sandy, acidulous soils; summer-autumn.
Distribution: wide-spread in north-western Europe.
