Cliostomum is a genus of lichenized fungi in the family Ramalinaceae. It has about 25 species.
Bryonora is a genus of crustose lichens in the family Lecanoraceae. The genus was circumscribed in 1983 by lichenologist Josef Poelt, with Bryonora castanea assigned as the type species.
Xenolecia is a genus of saxicolous (rock-dwelling) and crustose lichens in the family Lecideaceae. It has two species: X. cataractarum, and the type species, X. spadicomma. The genus was circumscribed by German lichenologist Hannes Hertel in 1987 to contain the type, a lichen known at that time only from the type locality on Wellington Island, Chile. Its range has since been expanded to include the Falkland Islands and northern Patagonia. X. cataractarum, found in Campbell Island, New Zealand was added to the genus in 2017.
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.
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 36 genera and about 600 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.
Coccotrema is a genus of lichen-forming fungi. It is the type genus of the family Coccotremataceae, in the order Pertusariales. The genus contains 16 species.
Tephromela is a genus of lichens in the family Tephromelataceae. There are about 25 species in this widespread genus.
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.
Hymenelia is a genus of lichen-forming fungi belonging to the family Hymeneliaceae.
Lambiella is a genus of lichen-forming fungi in the family Xylographaceae. The genus was circumscribed by German botanist Hannes Hertel in 1984, with Lambiella psephota assigned as the type species.
Hydropunctaria alaskana is a species of crustose lichen in the family Verrucariaceae. Found in Alaska, it was described as a new species in 2020 by Holger Thüs and Sergio Pérez-Ortega. The type specimen was collected from the Hoonah-Angoon Census Area in Glacier Bay National Park, where it was found growing on metamorphic rocks beside a creek. Buellia coniops and Verrucaria aethiobola were other lichens on the same rock. Hydropunctaria alaskana is also known to occur on Mitkof Island in Alaska, and on Vancouver Island in British Columbia.
Buellia sharpiana is a species of crustose lichen in the family Physciaceae. It was formally described as a new species in 2013 by lichenologists James Lendemer and Richard Harris. The type specimen was collected from the summit area of Mount Le Conte at an altitude of 6,300 ft (1,900 m). The specific epithet sharpiana honors Evelyn Bunches Sharp, wife of bryologist Aaron J. Sharp. The Sharps collected samples for the cryptogamic herbarium at the University of Tennessee at Knoxville, especially after the original collection was destroyed by a fire in 1998.
Buellia magaliesbergensis is a species of crustose lichen in the family Caliciaceae. Found in South Africa, it was formally described as a new species in 2021 by lichenologists John Alan Elix and Helmut Mayrhofer. The type specimen was collected in the Magaliesberg Range, at an altitude of 1,720 m (5,640 ft). Here the saxicolous lichen was found growing on rocks on the ground. The species epithet refers to the type locality, which is the only location where the lichen has been documented. The results of standard chemical spot tests are: thallus K+ (yellow), P+ (yellow-orange), and C−. Buellia magaliesbergensis contains norstictic acid as a major secondary chemical, and connorstictic acid as a minor compound.
Rhizocarpon haidense is a species of crustose lichen in the family Rhizocarpaceae. Found in Canada, it was described as a new species in 2020 by lichenologists Irwin Brodo and Alan Fryday. The type specimen was collected from the Skincuttle Inlet area of Moresby Island. Here it was found on the edge of a beach, growing on a rock at the base of a cliff. The specific epithet haidense references the type locality in Haida Gwaii.
Xenolecia cataractarum is a species of saxicolous and crustose lichen in the family Lecideaceae. It is only known to occur on Campbell Island, New Zealand.
Buellia dijiana is a species of terricolous (ground-dwelling), crustose lichen in the family Caliciaceae. It is found in Australia.
Tephromela lignicola is a species of lignicolous (wood-dwelling), crustose lichen in the family Tephromelataceae. It is found in the Falkland Islands, where it grows on fenceposts and similar timber.
Schaereria porpidioides is a species of saxicolous (rock-dwelling), crustose lichen in the family Schaereriaceae. It is found in the Falkland Islands.
Pseudephebe mariensis is a species of fruticose lichen in the family Parmeliaceae. It is found on Mount Maria in the Falkland Islands, where it grows in grassland and Empetrum-heath. The lichen is found from elevations ranging from 500 to 650 m.
