Parmotrema acrotrychum

Parmotrema acrotrychum is a species of lichen in the family Parmeliaceae. First discovered in Papua New Guinea, it was originally described in 1979 by Japanese lichenologist Syo Kurokawa as a species of Parmelia. Heinar Streimann transferred it to the genus Parmotrema in 1986. The lichen has also been found in Queensland (Australia) and Malaysia. It has been shown to contain a variety of secondary chemicals, including atranorin, fumarprotocetraric acid, succinprotocetraric acid, chloroatranorin, protocetraric acid, protolichesterinic acid, and lichesterinic acid.
