How to separate similar species

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

  • Lactifluus vellereus

    Larger, whitish and felted, with far less orange-brown coloration.

  • Oak milkcap (Lactarius quietus)

    Usually browner, differently scented, and without such abundant latex.
