The cap is with variable shades : rather violaceous but also red to green or brown; its margin is striate when mature. The cap surface is smooth, viscid in wet weather. The stem is white, without ring. The flesh is unchanging; its taste is acrid; the odour is fruity or of acid drops; its texture is grainy (breaking like a chalk stick). The gills are cream, free, emarginate or adnate, distant . The spore print is white. This species is mycorrhizal. It grows on the ground, in broad-leaved and coniferous woods, on a rather sandy soil, with oak most of the time, but also with birch. The fruiting period takes place from July to December.
Chemical tests : flesh becoming pinkish when in contact with iron sulphate; faint or no reaction to Gaïac; strong purple reaction of cap cystidia to sulpho-vanillin. Distinctive features : Cap with variable tints : purple, red, green, with a viscid frosty surface; flesh white and very fragile; edge of gills sometimes toothed (use magnifying glass); strong smell evoking coconut, pelargonium or sweets Russula fragilis is occasional and widely present in the forest of Rambouillet, and is frequent, more generally speaking . | ||
