Description

The most salient characteristic is the weak gills, which feel greasy to the touch, are flexible and do not break. The cap is 4-10 cm wide, convex at first and later flattened, and greenish to bright brown (they vary considerably in color). The stipe is pure white, slightly convex underneath, up to 10 cm in height and 1.5-2.5 cm in diameter. The spores are pure white.

Distribution and habitat

Russula cyanoxantha grows in slightly acidic, but nutrient-rich soil. Like all Russulas, it is a mycorrhizal fungus. They appear from May to November, with the highest concentration in July to September.
