Suillus sibiricus (Sing.) Sing., described from the Altai region in 1938, was later recorded in the Alps and the Pacific Northwest of North America. In Czechoslovakia, it was found in the Belanské Tatry mountains in 1970. This boletus forms mycorrhizal associations with Pinus cembra in Europe and Pinus sibirica in Asia. The occurrence of Tricholoma terreum as a second symbiont of Pinus cembra was also noted. The paper details ecological and distributional observations.
