The cap is pure white then creamy white and ochraceous at the disk, sometimes with coloured (pink, green, blue...) spots with age, conical-convex then expanded, often with a broad umbo; its margin is unrolled then often lobed, wavy, splitting with age. The cap surface is smooth, viscid when damp, drying quickly. The stem is white, with blue-green stains at the base, without ring nor ring zone. The flesh is white, unchanging; its taste is mild; the odour is indistinct, or very weak, of meal; its texture is fibrous. The gills are white, emarginate, crowded . The spore print is white. This species is mycorrhizal. It grows on the ground, in broad-leaved (sometimes coniferous) woods, forest edges, on a rather acid soil, with beech, birch, oak, chestnut, hornbeam. The fruiting period takes place from July to December.
Chemical tests : none. Distinctive features : entirely white mushroom; silky cap, slightly viscid and ochraceous at the disk, easily peelable into triangular chunks, with a wavy and split margin; blue-green stains typically present at the stem base, but not always; faint, mealy odour Tricholoma columbetta is quite rare and scattered in the forest of Rambouillet, and is occasional, more generally speaking . | ||
