Description

Cap: 3-8 cm in diameter; convex, finally slightly umbonate spreading; white when young, pale yellowish with age, not grayish-tinged; surface bare, dry; its margin infolded for a long time, becoming wavy with age.

Gills: Tooth-adnate; whitish or cream-colored.

Stem: 3-9 cm long, 1-1.5 cm thick; cylindrical, tapering downwards; whitish or brownish-yellow, browning on pressure; surface slightly fibrous.

Flesh: Quite hard; whitish; sweetish, aromatic, floury smell when cut, taste initially slightly floury, then quickly becomes peppery, with bitterish aftertaste.

Spore: White; 5-7 x 3.5-4.5 μm; ellipsoid, smooth.

Occurrence: From July to November; in deciduous forests, primarily under oak, common mushroom species in Hungary.

Edibility: Not edible.

Confusion: Similar to the not edible nauseating knight (T. lascivum), but its cap has a grayish tinge, its center is darker, its stem is whitish, becomes ochre-yellowish on pressure, and grows under beech. The edible dove-colored tricholoma's stem may be bluish spotted at the base, its white cap is silky shiny.

Note: The Tricholoma genus was created by Elius Magnus Fries, meaning hairy-edged. album comes from alba, meaning: white.

Species description: In 1770, Jacob Christian Schaeffer described this mushroom and named it Agaricus albus. A century later, in 1871, the German Paul Kummer mycologist transferred it to the tricholoma genus, and the name thus created is still accepted.
