The cap is pale ochre-cream to buff-ochre, more red-brown at its centre, convex then expanded; its margin is incurved and grooved-ribbed. The cap surface is matt, dry, silky. The stem is full, club-shaped or cylindrical and tapering at base, yellow to cream-ochre then stains with rust, the apex covered with dense yellow granular scales, without ring. The flesh is white, thick and firm, unchanging; its taste is variable: sometimes mild, or bitter-peppery, or of unripe apple upon chewing; the odour is faint, fruity; its texture is fibrous. The gills are whitish to cream, then spotted with rusty-brown, emarginate to slightly adnate, crowded, narrow . The spore print is white. This species is mycorrhizal. It grows on the ground, in broad-leaved or mixed woods, on a rather calcareous soil, mostly with oaks. The fruiting period takes place from July to November.
Distinctive features : Cap cream-yellow to buff, matt, with an incurved and typically grooved-ribbed margin; creamy-yellow stem dotted with lemon yellow scales at the apex; creamy-white gills stained with rust in bruises or with age; white flesh, often with unpleasant taste Tricholoma acerbum is quite rare and localised in the forest of Rambouillet, and is infrequent, more generally speaking . | ||
