Cap: 4-12 cm in diameter; convex when young, umbonate, then flattening; its center often remains umbonate; lemon yellow, olive-greenish-yellow base with greenish-brownish, olive-brownish or blackish, radially, innately fibrous; shiny when dry.

Gills: Tooth-adnate to the stem; whitish; their edges coarsely toothed.

Stem: 4-9 cm long, 1-3 cm thick; cylindrical, often tapering at the base; whitish or slightly yellowish-tinged; bare.

Flesh: Solid; white; floury smell, bitterish taste.

Spore: White; 5-7 x 4-6μm; elliptical, smooth.

Occurrence: From September to November; in deciduous and coniferous forests, not rare species.

Edibility: Not edible.

Confusion: Similar to the ringed, volva-stemmed, softer-fleshed, sweetish-smelling, mild-tasting, deadly poisonous death cap, and the yellow-gilled, mild-tasting grey tricholoma.

Note: The Tricholoma genus was created by the Swedish Elias Magnus Fries. tricholoma means hairy-edged. sejunctum is of Latin origin, meaning - separated, divided.

Species description: In 1799, when the British James Sowerby (1757-1822) described this species and named it Agaricus sejunctus, most gilled mushrooms were members of the agaricus genus. The famous French Lucien Quélet in 1872 transferred this species to the Tricholoma genus, so its scientific name became Tricholoma sejunctum.
