Remarks (public):Tricholoma album is generally smaller and more regularly shaped than T. stiparophyllum, and has distant, rather thick and irregular lamellae. The lamellae and lamellulae are of unequal width. It occurs mainly under Quercus. Tricholoma album var. thalliophilum differs by staining blue-green with thalliumoxide and suIfoformol (Bon, 1970). Since there are hardly any other morphological differences between var. thalliophilum and the typical variety, we do not attach much taxonomic value to it. Tricholoma lascivum differs by the more elongate spores and more frequent clamp-connections in pilei-, stipitipellis, and hymenium. Tricholoma resplendens (Fr.) P. Karst. sensu P. Karst. (1879) is likely misapplied for T. album, but the original description by Fries (1857) may refer to any species in section Lasciva or even to T columbetta (Fr.) Kumm. It is consequently considered a nomen dubium.

Lectotype (Iconotype): Agaricus albus Schaeff., Fung. Bavariae (1762) pl. 37.
Epitype (design. here): France, Territoire de Belfort, Le Salbert, NW of Belfort, 7 Oct. 1998, M. Christensen (MC 98094) (L, isoepitype in C).
Pileus 30-60(-75) mm, conico-campanulate with subinvolute margin, expanding to convex or plano-convex with small umbo, with deflexed then straight margin, white to pale yellow tinge, often with ochre-yellow centre when mature (Mu. 10 YR 8/2, 8-7/6 - 8, 2.5 Y 8/4-2, 7/6), smooth, glabrous, dry and dull, without radial structure. Lamellae, L = 5060, l= (1-)3-5(-7), rather distant, thickish, irregularly segmentiform to ventricose, 4-11 mm broad, entire lamellae and short lamellulae of unequal width, white to pale yellowish (K. & W. 4A2) with serrate edge. Stipe 30-60(-85) x 8-15 mm, cylindrical, broadened or tapering towards base, white to pale brownish yellow (2.5 Y 8/4), then with yellowish spots, becoming brownish when handled, glabrous to minutely granular-flocculose at apex, felted-subfibrillose to fibrillose in lower part, at base sometimes with white mycelial strands. Context white. Smell strong, a mixture of aromatical-sweet (cheap soap, honey) and an unpleasant component (radish), sometimes more farinaceous when cut. Taste very unpleasant, subfarinaceous at first, soon acrid mixed with bitter.
Spores (5.0-)5.5 -6.5(-7.0) x 3.5-4.5 (-5.0) µm, Q = 1.2-1.8, av. Q = 1.3-1.5, broadly ellipsoid to oblong with pronounced hilar appendage. Basidia 25-34 x 5.0-6.0 µm, 4-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis a cutis of cylindrical, 2.5-6.0 µm wide hyphae with scattered subclavate terminal elements, 20-50 x 3.0-9.0 µm; subpellis not differentiated from pileitrama, made up of cylindrical to inflated elements, 19-50(-70) x 3.0-12 µm. Pigment absent or very pale, intracellular. Clamp-connections very rare, practically absent on most septa in covering layers and hymenium.
Habitat & distribution - Ectomycorrbizal, mainly with Quercus on sandy and loamy soils. Widespread in Europe.
