Russula azurea
Description
Russula azurea belongs to the genus Russula, and family Russulaceae. It is a small to medium-sized mushroom. It is easily recognized by the exceptional bluish-violet color of the cap, the white lamellae and stem, and the non-bitter taste.
In a similar habitat, the Amethyst Dove (Russula amethystina) can be found with a wine cap, white stub and non-bitter taste. However, the lamellae turn yellow as the spores mature, as there is ocher spore pollen.
Common names: Russule azurée (French), Weißblättriger Reif-Täubling (German).
