Pileus 30-250 mm broad, conico-convex at first but soon expanding to convex or applanate, with or without a low, broad umbo, sometimes in old specimens irregularly concave with an undulating margin, pale grey-livid, grey-ochraceous or cream-color, smooth and glabrous or somewhat fluffy-rugulose at centre. Lamellae, L= up to 120-150, l = 1-3, moderately crowded, adnate or emarginate, narrowly segmentiform to broadly ventricose, when young with a distinct yellow color, soon changing into salmon-yellow to ochraceous-pink, but retaining the yellow colour for a long time, especially towards margin of pileus, with serrulate, concolorous edge. Stipe 40-150 x 5-35 mm, cylindrical or flexuose, sometimes compressed, often distinctly swollen towards base, but a extreme base often tapering again, white or tinged with cream-color or grey, subconcolorous with pileus, pruinose at apex, downward smooth, fibrillose. Context white, firm. Smell strong, difficult to describe, somewhat acidulous-nauseating or more farinaceous-rancid. Taste nasty-unpleasant.
Spores 8-11 x 7-9.5 µm, Q = 1.0-1.3, usually 6-angled. Basidia 4-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis an (ixo-)cutis of narrow, cylindrical hyphae, 2-5 µm wide, with pale yellow-brown, intracellular pigment. Clamps abundant.
Habitat: in deciduous forest, preferably under Quercus, and Fagus, sometimes also under Birch, on relatively heavy, clayey or loamy soils; late summer-Autumn.
Distribution: Wide-spread allover Europe, but more common in central and southern Europe than in the northwestern part.
