After analysing DNA from collections around the world, mycologists Jorinde Nuytinck, Annemieke Verbeken, and Steve Miller have concluded that L. deliciosus is a distinct European species that differs genetically, morphologically, and ecologically from populations in North America or Central America [REF].
Lactarius deliciosus is also very popular in Russian cuisine, and Siberian pine forests are a favourable habitat of this species.
