Forty-eight species and two varieties of the genera Cetraria, Hypogymnia, Parmelia, Parmeliopsis, and Platismatia in the lichen family Parmeliaceae are reported from a 13 400-km 2 area 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 – Boreal Alpine – Montane (13 taxa, 26%); Circumpolar, Boreal Montane (9 taxa, 18%); and American, Cordilleran (12 taxa, 24%). One new combination, Hypogymnia enteromorpha var. inactiva, is proposed.
