Cetreliopsis is a genus of four species of lichens in the family Parmeliaceae.
The genus was circumscribed by Ming-Jou Lai in 1980, with Cetreliopsis rhytidocarpa as the type species. [1]
In 2017, Divakar and colleagues used a recently developed "temporal phylogenetic" approach to identify temporal bands for specific taxonomic ranks in the family Parmeliaceae, suggesting that groups of species that diverged within the time window of 29.45–32.55 million years ago represent genera. They proposed to synonymize Cetreliopsis with Nephromopsis , along with several other Parmelioid genera, so that all the genera within the Parmeliaceae are about the same age. [2] Although some of their proposed taxonomic changes were accepted, the synonymization of the Parmelioid genera with Nephromopsis was not accepted. [3]
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.
Ahtiana is a genus of lichenized fungi known as candlewax lichens in the family Parmeliaceae. A monotypic genus, it contains the single species Ahtiana sphaerosporella or the mountain candlewax lichen, found in western North America. This species was segregated from the genus Parmelia by Canadian lichenologist Trevor Goward in a 1985 publication. It had been suggested that the genus include A. aurescens and A. pallidula based on similarities in morphology, but this transfer is not supported by molecular analysis.
Allocetraria is a genus of lichenized fungi in the family Parmeliaceae. It consists of 12 species, with a center of distribution in China.
Arctocetraria is a genus of foliose lichens in the family Parmeliaceae. It has three species.
Cetrariella is a genus of foliose Northern lichens in the family Parmeliaceae. It contains three species.
Kaernefeltia is a genus of lichenized fungi in the family Parmeliaceae.
Masonhalea is a genus of two species of lichenized fungi in the family Parmeliaceae.
Vulpicida is a genus of lichenized fungi in the family Parmeliaceae. Circumscribed in 1993 to contain species formerly placed in Cetraria, the genus is widespread in Arctic to northern temperate regions, and contains six species. The genus is characterized by the presence of the secondary metabolites pulvinic acid and vulpinic acid, compounds that when combined with usnic acid, give the species their characteristic yellow and green colors.
Tuckermannopsis is a genus of foliose lichens in the family Parmeliaceae.
Melanohalea is a genus of foliose lichens in the family Parmeliaceae. It contains 30 mostly Northern Hemisphere species that grow on bark or on wood. The genus is characterized by the presence of pseudocyphellae, usually on warts or on the tips of isidia, a non-pored epicortex, and a medulla containing depsidones or lacking secondary compounds. Melanohalea was circumscribed in 2004 as a segregate of the morphologically similar genus Melanelia.
Cetrelia is a genus of leafy lichens in the large family Parmeliaceae. They are commonly known as sea-storm lichens, alluding to the wavy appearance of their lobes. The name of the genus, circumscribed in 1968 by the husband and wife lichenologists William and Chicita Culberson, alludes to the former placement of these species in the genera Cetraria and Parmelia.
Parmotrema is a genus of lichen belonging to the family Parmeliaceae. It is a large genus, containing an estimated 300 species, with a centre of diversity in subtropical regions of South America and the Pacific Islands.
Nesolechia is a genus of parasitic fungi in the family Parmeliaceae. All three species in the genus grow on lichens. Nesolechia probably evolved from a lichen ancestor, as it is closely related to many lichenized species of fungi.
Cetrariopsis is a genus of foliose lichens in the large family Parmeliaceae. The genus contains three species, including the type, Cetrariopsis wallichiana.
Tuckermanella is a genus of lichen-forming fungi in the family Parmeliaceae.
Coelopogon is a genus of lichen-forming fungi in the family Parmeliaceae. The genus contains two species found in southern South America and South Africa.
Esslingeriana is a fungal genus in the family Parmeliaceae. The genus is monotypic, containing the single foliose lichen species Esslingeriana idahoensis, commonly known as the tinted rag lichen. It is found in northwestern North America.
Crespoa is a genus of five species of lichen in the family Parmeliaceae. Species in this genus are characterized by having an upper thallus surface that is wrinkled and reticulately ridged to coarsely foveolate.
Usnocetraria is a genus of foliose lichens in the family Parmeliaceae.
Raesaenenia is a fungal genus in the large family Parmeliaceae. It is a monotypic genus, containing the single lichenicolous fungus Raesaenenia huuskonenii, which parasitises lichens of genus Bryoria in the Northern Hemisphere.
