Canoparmelia is a genus of lichen-forming fungi in the family Parmeliaceae. The widespread genus contains about 35 species. Canoparmelia, a segregate of the parmelioid lichen genus Pseudoparmelia, was circumscribed by John Elix and Mason Hale in 1986.
Bulbothrix cinerea is a species of lichenized fungi within the family Parmeliaceae. Among other Bulbothrix species, only B. isidiza has isidia combined with an underside that is light coloured. B. isidiza's laciniae are wider, while its thallus is pale, and contains salazinic acid. In turn, B. ventricosa is larger and a black underside and rhizinae. The African species B. decurtata is an obligately saxicolous lichen, and while similar, it has a dark underside and produces salazinic acid in its medulla. The species' name thus refers to its uncommon dark gray colouration of its thallus.
Canoparmelia albomaculata is a species of lichen in the family Parmeliaceae. This species is very similar to the apostulate Canoparmelia caroliniana, showing the same colour, size and reticulate maculae. C. caroliniana, however, has true isidia. Big coralloid pustules that in some cases become sorediate are a characteristic feature for C. albomaculata.
Hypotrachyna angustissima is a species of foliose lichen in the family Parmeliaceae. This species is characterised by the occurrence of usnic acid in its cortex, and salazinic acid in its medulla and laminal isidia. In this it resembles Hypotrachyna microblasta, but the latter has wider laciniae and larger apothecia, and is laterally overlapping. Its epithet angustissima is derived from the Latin angusti, meaning "narrow", due to this species' very narrow laciniae.
Parmotrema zicoi is a species of saxicolous lichen in the family Parmeliaceae. Found in Brazil, it was introduced as new to science in 2002.
Bulbothrix meizospora is a species of foliose lichen in the family Parmeliaceae. It is found in Africa, Asia, and South America, where it grows on tree bark.
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).
Punctelia fimbriata is a species of foliose lichen in the family Parmeliaceae. Found in Brazil, it was formally described as a new species in 2007 by Luciana Canêz and Marcelo Marcelli. 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 tree trunk in an open field on an abandoned farm. It has a greenish-gray thallus measuring up to 10 cm (4 in) in diameter. The specific epithet fimbriata refers to the characteristic phyllidia of this species. Phyllidia are small, corticate, scale-like, dorsiventral structures that develop at the margins or on the upper surface of a lichen thallus. In Punctelia fimbriata, these delicate structures at the margins of the thallus may become lobulate (lobe-like) in age, and develop a "fringed" (fimbriate) appearance.
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.
Punctelia nashii is a species of foliose lichen in the family Parmeliaceae. It is known only from California.
Punctelia osorioi is a species of foliose lichen in the family Parmeliaceae. It is found in Brazil.
Punctelia constantimontium is a species of foliose lichen in the family Parmeliaceae. Its range includes South America, Africa, and Mexico, where it grows on bark and twigs.
Punctelia reddenda is a widely distributed species of foliose lichen in the family Parmeliaceae. It occurs in Africa, Europe, North America, and South America, where it grows on bark and on rock.
Punctelia riograndensis is a species of foliose lichen in the family Parmeliaceae. Found in Africa and South America, it was formally described as a new species by Norwegian lichenologist Bernt Lynge in 1914, as Parmelia riograndensis. The type specimen was collected in 1892 from Porto Alegre Municipality in Rio Grande do Sul State (Brazil) by Swedish lichenologist Gustav Malme. In 1982, Hildur Krog circumscribed the genus Punctelia to contain Parmelia species with rounded pseudocyphellae, and P. riograndensis was one of the 22 species that she transferred to the new genus.
Punctelia jujensis is a species of foliose lichen in the family Parmeliaceae. It is found in Argentina and Brazil.
Punctelia colombiana is a species of corticolous (bark-dwelling) and foliose (leafy) lichen in the family Parmeliaceae. It is found in South America.
Punctelia subpraesignis is a species of foliose lichen in the family Parmeliaceae. It occurs in Mexico, South America, and East Africa, where it grows on bark and on rocks. Major characteristics of the lichen that distinguish it from other Punctelia species include the C+ and KC+ rose spot tests of the medulla, ascospores that are smaller than 20 μm, and unciform (hooklike) conidia.
Punctelia punctilla is a species of foliose lichen in the family Parmeliaceae. It is found in Africa, South America, and North America, where it grows on bark and on rocks. The main characteristics that distinguish Punctelia punctilla from other species of Punctelia are the presence of isidia on the thallus surface, a pale brown thallus undersurface, and the presence of lecanoric acid in the medulla.
Punctelia bolliana, the eastern speckled shield lichen, is a species of foliose lichen in the family Parmeliaceae. It is found in North America, with a distribution extending from the Canadian province of Ontario south to the central and northeastern United States and Mexico. It grows on the bark of both deciduous trees and coniferous trees. The combination of characteristics that distinguishes this species from others in genus Punctelia are the absence of the vegetative propagules isidia and soralia, a pale brown lower thallus surface, and the presence of the secondary chemical protolichesterinic acid in the medulla.
Punctelia graminicola is a species of foliose (leafy) lichen in the family Parmeliaceae. It grows on rocks, and, less frequently, on bark in North America, South America, and East Africa. It has a blue-grey thallus measuring up to about 15 cm (6 in), covered with tiny pores called pseudocyphellae. Sometimes the lichen forms small lobes that project out from the surface. Fruiting bodies are uncommon in this species; if present, they resemble small cups with a brown internal disc measuring 3–10 mm (0.1–0.4 in) in diameter. A lookalike species, Punctelia hypoleucites, is not readily distinguishable from Punctelia graminicola by appearance or habitat alone; these species can only be reliably differentiated by examining the length of their conidia.
