Russula claroflava

Russula claroflava, commonly known as the yellow russula, yellow swamp russula or yellow swamp brittlegill, is a basidiomycete mushroom of the genus Russula. It has a yellow cap, white gills and stipe and bruises grey.

The species is found in wet places under birch and aspen woodlands across Europe and North America. It is mild-tasting and regarded as a good edible mushroom.

Taxonomy

It was described in 1888 by William Bywater Grove, based on a specimen from Sutton Park in the English Midlands. Its specific epithet is derived from the Latin clarus 'bright' or 'clear', and flava 'light yellow'.

Description

This medium-sized member of the genus Russula has a cap that is an egg-yolk yellow. Measuring 4–12 cm in diameter, 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,

Similar species

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

Distribution and 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.

Edibility

This mushroom is edible and good, with a mild taste, both in Europe and North America.
