2017Wild Icelandic Vegetation II (Bullseye Lichen Sheetlet) - Sheetlets

Common orange lichen (Xanthoria parietina) is a common lichen in places where maritime climate is prevalent in Iceland. It is widespread in the South and West of Iceland, growing on rocks, concrete walls and sometimes tree trunks. In bird cliffs the lichen can cover whole rock faces. It is quite big, often 6-10 cm in diameter and best distinguished from other lichens by distinctively leafy edges which can easily be pried loose from the underlay. It is very rare in the north of Iceland.
