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.
The Graphidaceae are a family of lichen-forming fungi in the order Graphidales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark.
Ramalina is a genus of greenish fruticose lichens that grow in the form of flattened, strap-like branches. Members of the genus are commonly called strap lichens or cartilage lichens. Apothecia are lecanorine.
Thelotrema is a genus of lichen-forming fungi in the family Graphidaceae, the family to which all taxa in the former Thelotremataceae now belong.
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.
Relicina is a genus of foliose lichens belonging to the large family Parmeliaceae. It contains 59 species.
Xanthoparmelia is a genus of foliose lichen in the family Parmeliaceae. Xanthoparmelia is synonymous with Almbornia, Neofuscelia, Chondropsis, Namakwa, Paraparmelia, and Xanthomaculina. This genus of lichen is commonly found in the United States, as well as Australia, New Zealand and Ecuador.
Hypotrachyna taylorensis is a species of foliose lichen in the family Parmeliaceae. Described by M.E. Mitchell in 1961, and transferred to genus Hypotrachyna by Mason Hale in 1975, the lichen occurs in the Appalachian region of North America.
Hypotrachyna parasinuosa is a species of foliose lichen in the family Parmeliaceae. Found in Ecuador, it was described as new to science in 2011.
Hypotrachyna guatemalensis is a species of foliose lichen in the family Parmeliaceae. Found in Guatemala, it was described as new to science in 2011.
Hypotrachyna indica is a species of foliose lichen in the family Parmeliaceae. Found in India, it was described as new to science in 2011.
Hypotrachyna paraphyscioides is a species of foliose lichen in the family Parmeliaceae. Found in Colombia, it was described as new to science in 2011.
Hypotrachyna paracitrella is a species of foliose lichen in the family Parmeliaceae. Found in Ecuador, it was described as new to science in 2011.
Hypotrachyna lueckingii is a species of foliose lichen in the family Parmeliaceae. Found in Costa Rica, it was described as new to science in 2011.
Klaus Kalb is a German lichenologist and an authority on tropical lichens.
Astrochapsa is a genus of lichen-forming fungi in the subfamily Graphidoideae of the family Graphidaceae. It has 28 species. The genus was circumscribed by Sittiporn Parnmen, Robert Lücking, and H. Thorsten Lumbsch in 2012, with Astrochapsa astroidea assigned as the type species. It was segregated from the genus Chapsa, from which it differs in having a more frequently densely corticate thallus, an apothecial margin that is mostly recurved, and the almost exclusively subdistoseptate, non-amyloid ascospores.
Halegrapha is a genus of lichen-forming fungi in the family Graphidaceae. It has nine species. The genus was circumscribed in 2011 by Eimy Rivas Plata and Robert Lücking, with Halegrapha chimaera assigned as the type species. The generic name honors American lichenologist Mason Hale.
Robert Lücking is a German lichenologist. He earned his master's and PhD from the University of Ulm, focusing on the taxonomy, ecology, and biodiversity of foliicolous lichens. He has received numerous awards for his work, including the Mason E. Hale award for his doctoral thesis, the Augustin Pyramus de Candolle prize for his monograph, and the Tuckerman Award twice for his publications in The Bryologist. Since 2015, he has been serving as the curator of lichens, fungi, and bryophytes at the Berlin Botanical Garden and Botanical Museum, and several lichen species and a genus have been named in his honour.
