Specimens of Agaricus bernardii (Quél.) Sacc., collected by the author on July 7, 1971, in northern Mongolia at the western foothills of the Khentey Mountains (ca. 1500 m), are described and illustrated in color. This species, described from Western Europe and typically growing in saline coastal meadows, was also found on saline soils in Hungary. The Mongolian material matches Western European specimens and confirms the presence of the species in steppe habitats. It has not yet been found in Czechoslovakia. A previously misidentified illustration from Bohemia actually represents Agaricus squamuliferus var. caroli. Vasilkov’s concept of A. bernardii likely refers to a collective species encompassing relatives from section Agaricus (= Sect. Campestres).
