Hypotrachyna brasiliana is a species of foliose lichen in the family Parmeliaceae. It was originally described by William Nylander in 1885 as a species of Parmelia. Mason Hale transferred it to the new genus Hypotrachyna in 1975. The lichen is found in the mountains of southeastern Brazil at elevations of 800–2,400 m (2,600–7,900 ft), where it grows on siliceous rocks, or on mosses over rocks.
