Russula vesca Fr. |
The cap is with variable shades : Bordeaux to brown (never violet); its margin is striate when mature. The cap surface is smooth, viscid in wet weather. The stem is white sometimes washed with yellow, without ring. The flesh is unchanging; its taste is mild; the odour is not distinctive; its texture is grainy (breaking like a chalk stick). The gills are white, adnate to decurrent, crowded (nb of gills per 90° ~ 39 ). The spore print is white. This species is mycorrhizal. It grows on the ground, in broad-leaved and coniferous woods, on a rather acid soil, with oak, beech, birch, chestnut, pine, spruce. The fruiting period takes place from May to December.
Chemical tests : flesh becoming quickly salmon pink when in contact with iron sulphate; faint purple reaction of cap cystidia to sulpho-vanillin. Distinctive features : cap colour resembling Old rose or ham pink; surface of cap shrinking and retreating with age 1 or 2mm away from margin, showing gills; gills rather thick, flexible and fragile; flesh with nutty taste, turning orange pink when in contact with iron sulphate Russula vesca is frequent and present everywhere in the forest of Rambouillet, and is frequent, more generally speaking . | ||
