Platismatia is genus of medium to large foliose lichens in the family Parmeliaceae. The genus is widespread and contains 11 species. They resemble many other genera of foliose lichens in the Parmeliaceae, particularly Parmotrema, Cetrelia, and Asahinea. Most species are found in forests on the trunks and branches of conifer trees, although some species grow on rocks. Species of Platismatia can be used to produce an orange-brown, yellow-brown, or brown dye, and at least one species was traditionally used to dye wool in Europe.
