Arctoparmelia

Arctoparmelia is a genus of ring lichens in the family Parmeliaceae. The genus was circumscribed by American lichenologist Mason Hale in 1986 with A. centrifuga (formerly in Xanthoparmelia) as the type species. Hale included five species in his original conception of the genus; the Siberian species A. collatolica was added in 2019.
