Remarks (internal):Entoloma pseudoexcentricum is a relatively poorly known species, probably because it is often neglected, and considered a form of E. rhodopolium, to which it indeed is very close.

Bibl.: Eyssartier et al., Bull. Soc. mycol. Fr. 115: 163-167, figs. 11-13. 1999; Noordeloos & Hausknecht in À–stter.Z. Pilzk. 3: 79-80. 1993.
Pileus 30-90 mm, hemispherical to bluntly campanulate at first, quickly expanding to plano-convex or applanate, with broad, large umbo, and undulating, deflexed marginal zone, strongly hygrophanous, when moist translucently striate up to one third of margin, when moist rather pale, usually a tinge of brown mixed with some grey or beige, clay-coloured, horn-brown, paler towards margin, strongly pallescent along radially streaks on drying, glabrous or very slightly rugulose, when dry strongly satiny-shiny. Lamellae rather crowded, adnate-emarginate, segmentiform to subventricose, purely white or pale cream-coloured then pink to salmon, with irregularly eroded, concolourous edge. Stipe 40-100 (-120) x 4-13 mm, cylindrical, flexuous, somewhat attenuate towards base, very pale, much paler than pileus, almost white, fibrous with rather fine silky longitudinal fibrils. Context rather elastic, thin, concolourous with surface. Smell and taste farinaceous.
Spores 9.5-11.5 (-12) x 7.0 - 8.0 µm, Q = 1.15-1.4, subheterodiametrical in side view with 6-7 angles. Basidia 30-50 x 7.0-9.0 µm, 4-, rarely also 2-spored, clamped. Lamella edge fertile. Cystidia absent. Hymenophoral trama regular, made up of short, inflated elements, 25-110 x 7-23 µm. Pileipellis a cutis of narrow, cylindrical, 2.5-7 (-9) µm wide hyphae; subpellis made up of inflated elements. Pigment very pale, intracellular, and hardly detectable. Clamp-connections present.
Habitat and distribution: terrestrial, associated with Populus species on damp, sandy or loamy soils. Distribution not well known, but probably widespread in Europe.
