Remarks (internal):Entoloma mougeotii is distinctive because of its delicate violaceous-brown colour and sterile lamella edge with large cheilocystidia. It has a wide distribution all over Europe, but only in very special grassland habitats, for which it is a good indicator species (Vesterholt 2002).

Lamellae adnate, or with a decurrent tooth, white then pink, with concolorous, fimbriate margin. Stipe 20-60 x 1-4 mm, cylindrical to slightly compressed, with longitudinally groove, steel-grey, at first longitudinally fibrillose, then smooth shiny, white tomentose at base.

Spores (8.5-)9-11.5(-12) x 6-8 µm, Q = 1.2-1.6, heterodiametrical, with 5-8 pronounced angles. Basidia 27-48 x 10-14 µm, 4-spored. Lamella edge sterile. Cheilocystidia 16-60(-80) x 7-17 µm, cylindrical to slenderly clavate. Pileipellis a trichoderm, made up of inflated cylindrical to clavate, or utriform terminal elements, 6-25 µm wide. Pigment violaceous-brown, intracellular. Clamps absent from all tissues.
