The genus Punctelia Krog gen. nov., comprising subgen. Punctelia (the Parmelia borreri group) and subgen. Flavopunctelia Krog subgen. nov. (the Parmelia flaventior group), is here segregated from Parmelia s. str. The main differences between the two genera lie in the development of the pseudocyphellae, the chemical properties of the medulla, and the centres of distribution. Parmelia s. str. has its highest number of species in East Asia and the Australian region, Punctelia in the Americas and Africa.
