Trapelia is a genus of lichenized fungi in the family Trapeliaceae.
Acanthothecis is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909.
Cladia is a genus of lichenized fungi in the family Cladoniaceae. Cladia species have a crustose primary thallus and a fruticose, secondary thallus, often referred to as pseudopodetium. The type species of the genus, Cladia aggregata, is widely distributed, occurring from South America, South Africa, Australasia and South-East Asia to southern Japan and India. Most of the other species are found in the Southern Hemisphere.
Japewiella is a genus of lichen in the family Lecanoraceae. It was circumscribed in 2000 by German botanist and lichenologist Christian Printzen as a segregate of the genus Japewia. The genus name of Japewia was in honour of Peter Wilfrid James, who was an English botanist. The genus was circumscribed by Christian Printzen in Bryologist vol.102 on page 715 in 1999.
Lecidella is a genus of crustose lichens in the family Lecanoraceae.
Pyrrhospora is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855, with Pyrrhospora quernea assigned as the type species.
Rhizocarpon is a genus of crustose, saxicolous, lecideoid lichens in the family Rhizocarpaceae. The genus is common in arctic-alpine environments, but also occurs throughout temperate, subtropical, and even tropical regions. They are commonly known as map lichens because of the prothallus forming border-like bands between colonies in some species, like the common map lichen.
Lepraria is a genus of leprose crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains. Members of the genus are commonly called dust lichens. The main vegetative body (thallus) is made of patches of soredia. There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products are important characters to distinguish between similar species in Lepraria.
Chrysothrix is a genus of lichen-forming fungi in the family Chrysothricaceae. They are commonly called gold dust lichens or sulfur dust lichens, because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia. Apothecia are never present in North American specimens.
Phlyctis is a genus of lichenized fungi in the order Gyalectales, and the type genus of the family Phlyctidaceae. Members of the genus are commonly called blemished lichens.
Megalaria is a genus of lichen-forming fungi in the family Ramalinaceae. The genus was circumscribed by Austrian lichenologist Josef Hafellner in 1984, with Megalaria grossa assigned as the type species.
Tephromela is a genus of lichens in the family Tephromelataceae. There are about 25 species in this widespread genus.
Neoprotoparmelia is a genus of crustose lichens that was created in 2018. It contains 24 tropical and subtropical species that mostly grow on bark. Neoprotoparmelia is in the subfamily Protoparmelioideae of the family Parmeliaceae, along with the morphologically similar genera Protoparmelia and Maronina.
Gintaras Kantvilas is an Australian lichenologist, who earned his Ph.D in 1985 from the University of Tasmania with a thesis entitled Studies on Tasmanian rainforest lichens. He has authored over 432 species names, and 167 genera in the field of mycology.
Catillaria is a genus of crustose lichens in the family Catillariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852. It is the type genus of Catillariaceae, which was circumscribed by Austrian lichenologist Josef Hafellner in 1984.
Loxospora is a genus of lichen-forming fungi in the family Sarrameanaceae. It has 13 species. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852, with Loxospora elatina assigned as the type species. This crustose lichen was originally named Lecanora elatina by Erik Acharius in 1810.
Lepra is a genus of lichen-forming fungi in the family Pertusariaceae. Although the genus was created in 1777, it was not regularly used until it was resurrected in 2016 following molecular phylogenetic analyses. It has more than 80 species, most of which were previously classified in genus Pertusaria.
Schizotrema is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 2009 by Armin Mangold and H. Thorsten Lumbsch.
