How to separate similar species

Compare especially with these similar species: Lactarius vellereus, Lactifluus piperatus. 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.

Similar species

  • Fleecy milkcap (Lactarius vellereus)

    Fleecy milkcap has a velvety-felted cap and exudes acrid white latex when damaged.

  • Lactifluus piperatus

    Peppery milkcap has very crowded gills and abundant acrid white latex; Russula delica has no latex.
