Lactarius deliciosus, commonly known as the Saffron milk cap, Red pine mushroom, is one of the best known members of the large milk-cap genus Lactarius in the order Russulales. It is found in Europe and has been accidentally introduced to other countries under conifers and can be found growing in pine plantations. Michael Kuo, primary founder of the MushroomExpert website, cites Belgian mycologist Jorinde Nuytinck who determined that the mushroom is a "genetically, morphologically, and ecologically distinct European species that does not occur in North America".
