Parmotrema perforatum, commonly known as the perforated ruffle lichen, is a species of foliose lichen in the family Parmeliaceae. The lichen was first formally described as new species in 1787 by Nikolaus Joseph von Jacquin. It was transferred to the genus Parmotrema by Italian lichenologist Abramo Bartolommeo Massalongo in 1860. The lichen is characterized by its apothecia (fruiting body) often having a perforated hole in the center. The genus Parmotrema has a naked (white) zone on the underside margin and often has long hair-like projections on the lobe edges called cilia; P. perforatum is no different.
