Platismatia erosa is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae. Found in Asia, it was formally described as a new species in 1968 by William and Chicita Culberson. The species epithet erosa refers to the "eroded" quality of the reticulations on the upper thallus surface.[1] The lichen has been recorded from Japan, Taiwan, Java, Vietnam, Nepal, the Philippines, and Sikkim, and Tibet. Chemical analysis of the lichen (using thin-layer chromatography) revealed two lichen products previously unknown in genus Platismatia, pannaric acid and jackinic acid. Two chemotypes of P. erosa have been identified, containing different proportions of these substances.[2]
