Arctoparmelia incurva is a species of saxicolous (rock-dwelling), foliose lichen in the family Parmeliaceae. First described in 1794 by Christiaan Hendrik Persoon, it has undergone several taxonomic reclassifications before being placed in its current genus in 1986. This yellowish-green lichen, characterised by its narrow, convex lobes and globular soralia, typically grows on sun-exposed siliceous rocks in alpine and arctic habitats. It has a circumpolar distribution, found across North America, Europe, and parts of Asia. A. incurva can be distinguished from similar species by its specific morphological features and chemical spot test reactions.
