Russula decipiens (Singer) Svr?ek |
The cap is purple-red to vinaceous red, but discolouring to olivaceous-ochre in the middle, flat then soon depressed, often deformed; its margin is smooth at first, then later furrowed with age. The cap surface is smooth, peelable half-way through, matt in dry weather, but viscid under wet weather conditions. The stem is cylindrical or thicker at the base, full then hollow, white and longitudinally veined, becoming greyish starting from these veins. The flesh is white, firm, turning grey; its taste is mild at first then hot; the odour is faint, fruity; its texture is grainy (breaking like a chalk stick). The gills are cream at first, then bright golden yellow, emarginate to slightly adnate, crowded, broad . The spore print is orange yellow. This species is mycorrhizal. It grows on the ground, in broad-leaved woods, mostly with oak or beech. The fruiting period takes place from July to November.
Chemical tests : stem becoming pink to vinaceous red when in contact with iron sulphate; blue to pale grey with gaïac, vinaceous brown with phenol. Distinctive features : Reddish cap, discolouring to ochre-olive at the centre; orange yellow gills; stem and flesh turning grey; flesh with acrid taste; with broad-leaved trees Russula decipiens is quite rare and localised in the forest of Rambouillet, and is occasional, more generally speaking . | ||
