Bulbothrix is a genus of lichen-forming fungi in the family Parmeliaceae. Established in 1974 by the American lichenologist Mason Hale as a segregate from the genus Parmelia, Bulbothrix comprises about 40 accepted species as of 2025. These foliose lichens are distinguished by their characteristic black, bulb-tipped hairs (cilia) along the lobe edges and are found roughly equally divided between the Old World and New World, growing predominantly on trees in lowland rainforests and shrublands.
