Arctoparmelia separata, commonly known as the rippled ring lichen,[2] is a species of foliose, ring lichen in the family Parmeliaceae with a roughly circumpolar distribution.
Taxonomy
The lichen was first described scientifically by Theodor Magnus Fries in 1879 as a species of Parmelia.[3] Mason Hale transferred it to Xanthoparmelia in 1974.[4] In 1986, Hale segregated five Xanthoparmelia species to the newly created genus Arctoparmelia in 1986. This group of species, including X. separata, is characterized by the velvety, ivory-white to purplish colour of the lower surface of the thallus, the presence of alectoronic acid, and a geographical range restricted to arctic or boreal locations.[5] Arctoparmelia separata is commonly known as the rippled ring lichen.[6]
Description
Arctoparmelia separata resembles the more common Arctoparmelia centrifuga, but is distinguished from that species by the dull mouse-grey colour of its lower surface, and its thicker and more rigid thallus,[6] and its long lobes that are divaricately branched. The lichen has an incompletely circumpolar distribution. It has been recorded from northern North America,[6] Greenland,[7] and Japan, and Siberia west to Novaya Zemlya.[5] It has not been recorded in continental Europe.[8]
