Abstract: Ten species of Lycoperdaceae classified into three genera, Bovista, Calvatia and Lycoperdon are reported from the Beartooth Plateau, Rocky Mountains, U.S.A. All are new records for this alpine area. Among them, Lycoperdon frigidum is a new record for the lower 48 States. Also, an alpine record of Calvatia booniana extends the known habitat of this fungus in North America.

Introduction: The Rocky Mountains extend Montana and Wyoming which is part of the along the spine of North America, continuing Middle-Northern Rocky Mountain Floristic Zone 5,000 km from Canada to New Mexico, U.S.A. with tree-lines at ca. 3,000 m elevation (Cripps & The Beartooth Plateau is located north of Horak 2008). The Beartooth plateau has rich Yellowstone National Park along the border of alpine vegetation, consisting of woody Salix 160 Kasuya.
