Pseudocyphellaria perpetua is a species of corticolous (bark-dwelling), foliose (leafy) cyanolichen in the family Peltigeraceae. It was described as new to science in 2002 by lichenologists Bruce McCune and Jolanta Miądlikowska.[1] It is distinguished from similar species, including some forms of P. crocata, by its yellow medulla and mostly marginal soralia. Other characteristics include its narrow, linear lobes, and its pale lower undersurface.[1] Some molecular phylogenetic analysis suggests that Pseudocyphellaria perpetua and P. crocata are morphotypes of the same phylogenetic species.[2] P. perpetua occurs on both conifer and hardwood trees in oceanic areas of the western North America and in the Russian Far East.[1] It has also been documented as an uncommon species in Nova Scotia (eastern Canada).[3]
