How to separate similar species

Compare especially with these similar species: Russula foetens, Russula emetica. Check the combination of cap shape and colour, spore-bearing surface, stem, flesh changes and habitat. A single feature or photograph is not enough; if the key characters do not match the description, do not treat the identification as confirmed.
