Opegrapha perturbans

Species of lichen

Opegrapha perturbans is a species of lichenicolous (lichen-dwelling) fungus in the family Arthoniaceae. Discovered on the Pacific coast of Chile, it was described as new to science in 2003 by Gerhard Follman. The holotype was collected in Coquimbo, north Chile in 1838 by the French naturalist Claude Gay. The fungus grows specifically on the thallus of Ingaderia pulcherrima, a fruticose lichen. The species epithet perturbans refers to the long-standing mistaken identity of its ascomata with the true fructifications of its host lichen.
