Parmelia is a genus of medium to large foliose lichens. It has a global distribution, extending from the Arctic to the Antarctic continent but concentrated in temperate regions. There are about 40 species in Parmelia. In recent decades, the once large genus Parmelia has been divided into a number of smaller genera according to thallus morphology and phylogenetic relatedness.
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.
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 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.
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.
Everniopsis is a fungal genus in the family Parmeliaceae. It consists of a single species, the bark-dwelling lichen Everniopsis trulla, which occurs in Africa and South America.
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.
Cetraria aculeata or the spiny Iceland lichen is a dark brown to black fruticose, soil Iceland lichen from the family Parmeliaceae. The species was first described by German naturalist Johann Christian Daniel Edler von Schreber in 1771 under the name of Lichen aculeatus. Later on Erik Acharius, the "father of lichenology" gave it a name of Cornicularia aculeata, which lately has been changed to Coelocaulon aculeatum. Finally the taxonomic revision of Ingvar Kärnefelt and colleagues assigned the species to the genus Cetraria.
Jan Eric Ingvar Kärnefelt is a Swedish lichenologist.
Melanohalea zopheroa is a species of lichen in the family Parmeliaceae. It was first formally described in 1977 by Ted Esslinger as Parmelia zopheroa. A year later, he transferred it to the new genus Melanelia, which he created to contain the brown Parmeliae species. In 2004, after early molecular phylogenetic evidence showed that Melanelia was not monophyletic, Melanohalea was circumscribed by lichenologists Oscar Blanco, Ana Crespo, Pradeep K. Divakar, Esslinger, David L. Hawksworth and H. Thorsten Lumbsch, and M. zopheroa was transferred to it. The lichen has a disjunct distribution, as it is found in South America (Chile) and in New Zealand.
Melanohalea subverruculifera is a species of lichen in the family Parmeliaceae. Found in China, it was first formally described as a new species in 1980 as Parmelia subverruculifera. It was transferred to the segregate genus Melanelia in 1991, and then to the genus Melanohalea in 2004.
Usnocetraria is a genus of foliose lichens in the family Parmeliaceae.
Allocetraria corrugata is a species of foliose lichen in the family Parmeliaceae. It is found in high-elevation locations in Yunnan, China, where it grows on rocks with mosses.
