Russula fageticola Melzer ex S. Lundell |
The cap is bright red to carmine red, convex then depressed; its margin is smooth. The cap surface is smooth, not viscid nor sticky. The stem is pure white, without ring. The flesh is white, unchanging or very slightly yellowing; its taste is acrid; the odour is faint, fruity or of coconut for young specimens; its texture is grainy (breaking like a chalk stick). The gills are white, crowded . The spore print is white. This species is mycorrhizal. It grows on the ground, under broad-leaved trees, on a rather neutral to acid soil, most of the time with beech, sometimes oak. The fruiting period takes place from October to November.
Chemical tests : flesh becoming ochraceous (without orange) when in contact with iron sulphate; positive reaction to Gaïac (quite bright blue); strong purple reaction of cap cystidia to sulpho-vanillin. Distinctive features : Bright scarlet-red cap, slightly depressed and not discoloured to yellow; firm flesh (unlike R. mairei or R. emetica); white gills, with a greenish tinge; under beech Russula fageticola is quite rare and scattered in the forest of Rambouillet, and is very frequent, more generally speaking . | ||
