Punctelia purpurascens is a species of foliose lichen in the family Parmeliaceae. Found in Brazil, it was formally described as a new species in 2007 by lichenologists Marcelo Marcelli and Luciana da Silva Canêz. The type specimen was collected in the municipality of Vicara in the southern Brazilian state of Rio Grande do Sul. There it was found growing on a basaltic rock in an open field. The specific epithet purpurascens refers to the unusual K+ purple reaction of the medulla.

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

Canoparmelia subroseoreagens is a species of foliose lichen in the family Parmeliaceae. Found in Brazil, it was formally described as a new species in 2009 by lichenologists Marcelo Marcelli, Luciana da Silva Canêz, and John Elix. The type specimen was collected from a Brazilian pine forest in Fazenda da Estrela (Vacaria, Rio Grande do Sul) at an altitude of 905 m (2,969 ft), where it was found growing on tree bark. The lichen is named for its similarity to Canoparmelia roseoreagens (found in the same locality) but that species produces isidia rather than soredia. Canoparmelia subroseoreagens

Canoparmelia roseoreagens is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae.

Canoparmelia consanguinea is a species of saxicolous (rock-dwelling), foliose lichen in the family Parmeliaceae. Found in Brazil, it was formally described as a new species in 2009 by lichenologists Marcelo Marcelli, Luciana da Silva Canêz, and John Elix. The type specimen was collected from an open field in Fazenda da Estrela (Vacaria, Rio Grande do Sul) at an altitude of 920 m (3,020 ft), where it was growing on basaltic rock.

Punctelia osorioi is a species of foliose lichen in the family Parmeliaceae. It is found in Brazil.

Punctelia nashii is a species of foliose lichen in the family Parmeliaceae. It is known only from California.

Punctelia involuta is a species of foliose lichen in the family Parmeliaceae. Found in Brazil, it was described as a new species in 2010 by Luciana Canêz and Marcelli Marcelo. It is a member of the Punctelia microsticta species group, a set of related Punctelia lichens with a black lower surface and similar morphology. The type specimen of Punctelia involuta was collected in São Luiz do Paraitinga at the Serra do Mar State Park. In an open forest there it was found growing on mosses at the base of a thin, rotting Myrtaceae trunk; the elevation was 975 m (3,200 ft). The thallus of Punctelia

Punctelia ruderata is a species of foliose lichen in the family Parmeliaceae. It is a member of the Punctelia rudecta species complex. Found in Asia and East Africa, it was first formally described as a new species in 1921 by Finnish lichenologist Edvard August Vainio as Parmelia ruderata. The type was collected by Atsushi Yasuda in Honshu, Japan, where it was found growing on tree bark. The lichen was reported from South America in a 2009 Ph.D. thesis, and the taxon transferred to the genus Punctelia. The new combination, however, was not validly published, and molecular phylogenetic
