Remarks (internal):Entoloma saepium can be distinguished from pale forms of E. clypeatum in the rather regular, non-hygrophanous, not striate pileus with its pale creamy colour, and also in the orange or reddish yellow discolouration of the context, particularly in the stipe (insect holes). Entoloma saundersii differs in having more grey tinges in the pileus with micaceous patches, and distinctly larger spores. Entoloma niphoides occurs in the same habitat as E. saepium but differs in having an almost purely white pileus, and in a context that does not discolour on bruising.

Pileus 25-110 mm, conical to conico-convex then expanding to plano-convex or applanate with broad, low umbo, with involute margin when young, marginal zone usually regular, not hygrophanous, not translucently striate, greyish or yellowish cream to very pale brown, rarely with reddish ochraceous flush, particularly in exposed specimens, not or only slightly pallescent on drying, rather regularly radially, innately fibrillose, when exposed sometimes rugulose or tomentose at centre, and/or radially splitting, showing the reddish pileitrama between the fibrils. Lamellae, L = 50-60, l = 3-5-7, moderately crowded, deeply emarginate, segmentiform to ventricose, thin, creamy white then pink without any trace of brown or grey (Mu. 7.5 YR 7/4-6/4) with subentire to coarsely eroded, concolorous edge. Stipe 30-110 x (5-) 8-16 (-24) mm, cylindrical, sometimes flexuose, usually distinctly broadened towards base, very firm, solid, minutely to coarsely fibrillose-striate to costate, sometimes, especially near base and when bruised, with reddish ochraceous fibrils, elsewhere almost purely white. Context firm, white, when bruised discolouring reddish-ochraceous. Smell farinaceous. Taste strongly farinaceous.
Spores (7.0-)8.0-11.0 x (6.5-) 8.0-10.0(-11.0) µm, Q = 1.0-1.25, Qav = 1.15, isodiametrical to broadly ellipsoid, 5-7-angled in side-view. Basidia 35-50 x 11-17 µm, 4-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis an ixocutis of radially arranged, cylindrical, 1.5-7 inn wide hyphae. Pigment pale brown, intracellular in pileipellis and upper pileitrama. Clamp-connections abundant in all tissues.
Habitat & distr. - Solitary or caespitose, often in large fairy-rings under Prunus spinosa and cultivated Prunus-species (fruit trees), fairly common. widespread all over W. and S. Europe. April-June.
