A revision is made of the lichen family Parmeliaceae in Dominica, based on previous published records by Elliott and on collections by the author. Twenty-two species are now known for Parmelia, the only genus in this family on the island. A new species, Parmelia mordenii, is described from rock habitats in the dry scrub woodland.
