Parmotrema aberrans
Parmotrema aberrans is a species of lichen in the family Parmeliaceae. It is found in the Neotropics, from Mexico to Paraguay. The species was originally described by Edvard August Vainio in 1890 as a form of "Parmelia xanthina". In 1958, Henry Nicollon des Abbayes promoted it to species level within "Parmelia". Luciana Canêz and Marcelo Marcelli transferred it to "Parmotrema" in 2008.

Characteristics of "Parmotrema aberrans" include a greenish-yellow thallus (due to the presence of usnic acid), continuous cilia on the margins, cylindrical isidia with cilia, and the presence of gyrophoric acid in the medulla. "Parmotrema xanthinum" is quite similar in appearance and morphology, but lacks medullary gyrophoric acid.

The lichenicolous fungus "Macroskyttea parmotrematis" (Helotiales), reported as a new genus and species in 2015, inhabits the thalli of "Parmotrema aberrans" (as well as "P. ultralucens").
