Russula mairei

Russula mairei, commonly known as the Beechwood Sickener, is a basidiomycete mushroom of the genus Russula.

Description
The cap is a red or rosy colour, 3–6 cm wide, convex to flat, or slightly depressed, and weakly sticky. Taste sharp. The gills are narrowly spaced, white, often with a faint blue-green sheen. The stipe is 2–5 cm long, 1–1.5 cm wide, cylindrical, white.

Distribution
Not surprisingly given the name, the Beechwood Sickener can be found growing under beech.
