Arctoparmelia
Sign in to saveArctoparmelia is a genus of foliose lichens in the family Parmeliaceae. Established in 1986, the genus comprises five species of rock-dwelling lichens found primarily in arctic and boreal regions of the Northern Hemisphere. These lichens are characterized by their distinctive velvety or ivory-white to pale brown lower surfaces, concentric growth patterns, and unique chemistry, including the presence of alectoronic acid and negative reactions to iodine-based tests. Arctoparmelia species, commonly known as ring lichens, vary in size from small thalli to specimens up to in diameter, and typically

Arctoparmelia is a genus of foliose lichens in the family Parmeliaceae. Established in 1986, the genus comprises five species of rock-dwelling lichens found primarily in arctic and boreal regions of the Northern Hemisphere. These lichens are characterized by their distinctive velvety or ivory-white to pale brown lower surfaces, concentric growth patterns, and unique chemistry, including the presence of alectoronic acid and negative reactions to iodine-based tests. Arctoparmelia species, commonly known as ring lichens, vary in size from small thalli to specimens up to in diameter, and typically grow on exposed rocks in cold, dry environments. While most species show broad circumpolar distributions, some are restricted to specific regions.
