Species of Calvatia (Lycoperdaceae) from arctic and subarctic regions are described. The diagnostic characters in Calvatia are discused with emphasis on strutures of peridium and capillitium and colour of gleba. Ten species are recognized. Three species: C. Candida, C. excipuliformis, C. utriformis are confined to subarctic stations, while seven species have their main distribution in the arctic zones. Three of these are new species: C. connivens, C. horrida, C. septentrionalis , while three other species are redefined after studies of type material: C. arctica, C. bellii and C. turneri. Several specimens studied show characters pointing to a hybrid origin.
