Russula luteotacta Rea |
The cap is red to rose, discoloured to whitish patches, convex then shortly funnel-shaped; its margin is smooth. The cap surface is smooth, viscid in wet weather. The stem is white, sometimes washed with pink or red, becoming yellow when pressed, without ring. The flesh is white, yellowing slowly (>1h) on stem and gills; its taste is acrid; the odour is faint, fruity, of honey or coconut; its texture is grainy (breaking like a chalk stick). The gills are white, turning yellow strongly when pressed or bruised, slightly but distinctively decurrent, crowded (nb of gills per 90° ~ 24 ). The spore print is white. This species is mycorrhizal. It grows on the ground, under broad-leaved trees, on damp clayey soil or in the mud, on a rather calcareous soil, most of the time with oak. The fruiting period takes place from July to November.
Chemical tests : flesh becoming pale orange when in contact with iron sulphate; positive reaction to Gaïac (bright blue);. Distinctive features : matt cap surface, pinkish red, not easily peeled off; intense yellowing when bruised especially on gills and stem after several hours; in damp soils with broad-leaved trees (preferring oaks) Russula luteotacta is quite rare and localised in the forest of Rambouillet, and is infrequent, more generally speaking . | ||
