This is a taxonomic study of Cintractia spp. on nearly one hundred host species, mainly in Canada, northern United States, and southern Alaska. Coverage is very incomplete for northern Alaska, Greenland, and parts of the Canadian arctic archipelago. Eighteen species and varieties are recognized including one new species, Cint. atratae, and four new varieties, Cint. carpophila vars. kenaica and verrucosa and Cint. caricis vars. intermedia and acutarum. Two recombinations are made. The biology and phylogeny of the group are also discussed.
