Forty-eight species and two varieties of the generaCetraria, Hypogymnia, Parmelia, Parmeliopsis, andPlatismatiain the lichen family Parmeliaceae are reported from a 13ensp;400-km2area in the mountains and foothills of southwestern Alberta. Twelve of these taxa are new to Alberta. The distribution and habitats occupied by each of the taxa are described. Thirty-four (67) of the taxa are of Circumpolar distribution and 17 (33) are endemic to North America. The three best represented distribution elements are Circumpolar, Arctic ndash; Boreal Alpine ndash; Montane (13 taxa, 26); Circumpolar, Boreal Montane (9 taxa, 18); and American, Cordilleran (12 taxa, 24).
