§1

Description

This medium-sized member of the genus Russula has a cap that is an egg-yolk yellow. Measuring 4–12 cm (1.5–4.5 in) in diameter, it is slightly sticky when moist, and leaves and other debris often stick to it. There is usually a slight depression in the centre of mature specimens, with the margin becoming furrowed. The cap is half peeling. The stem is 3–8 cm long, white, fairly firm, straight and 1–2 cm thick. Its gills are pale ochre, and are adnexed to almost free. All parts turn dark grey on aging or bruising. The smell is fruity and the spore print is pale ochre, and the oval warty spores average 9.5 x 8 μm.

Similar species. The edible but acrid Russula ochroleuca resembles this species, but has a duller yellow cap. R. lutea is also similar.

Range & habitat

Russula claroflava appears in summer and autumn, usually with birch (Betula), or aspen (Populus), on heaths and moors, preferring damp places near ponds or lakes, often occurring in sphagnum. It is occasionally found in drier places. It occurs in Britain, across northern Europe, and throughout North America.
