A revision of the lichen genus Hypotrachyna (Parmeliaceae) in tropical America

Hale, Mason E. (author.). Smithsonian Institution. Press, (publisher.).

Summary: A revision is made for 77 species of Hypotrachyna occurring in tropical America. Fifty-eight of these are endemic to the New World. These species are classified loosely in chemical constellations based on the secondary depside-depsidone products. The possible role of hybridization of fertile species and the evolution of vegetative morphs are discussed. Five new species are described: H. andensis, H. lopezii, H. partita, H. producta, and H. protenta. The remaining 72 species are transferred from the genus Parmelia to Hypotrachyna.
