This is a list of species in the lichen genus Caloplaca . Although there were estimated to be more than 500 species in 2008, [1] the family Teloschistaceae has undergone major revisions since then. Several molecular phylogenetic studies have been published that have established a phylogenetic framework to more appropriately classify lichens that were previously grouped in Caloplaca. [2] [3] [4] [5] As of December 2023 [update] , Species Fungorum (in the Catalogue of Life) accepts 173 species of Caloplaca. [6]
The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family has a cosmopolitan distribution, although its members occur predominantly in temperate regions. Most members are lichens that either live on rock or on bark, but about 40 species are lichenicolous – meaning they are non-lichenised fungi that live on other lichens. Many members of the Teloschistaceae are readily identifiable by their vibrant orange to yellow hue, a result of their frequent anthraquinone content. The presence of these anthraquinone pigments, which confer protection from ultraviolet light, enabled this group to expand from shaded forest habitats to harsher environmental conditions of sunny and arid ecosystems during the Late Cretaceous.
Gallowayella is a genus of lichen-forming fungi in the family Teloschistaceae. It has 15 species. The genus was circumscribed in 2012 by Sergey Kondratyuk, Natalya Fedorenko, Soili Stenroos, Ingvar Kärnefelt, Jack Elix, and Arne Thell, with Gallowayella coppinsii assigned as the type species. The generic name honours New Zealand lichenologist David John Galloway (1942–2014).
Gyalolechia is a genus of lichen-forming fungi belonging to the family Teloschistaceae. It contains 18 species of crustose lichens.
Calogaya is a genus of lichen-forming fungi belonging to the family Teloschistaceae. It has 19 species. The genus was circumscribed in 2013 by Ulf Arup, Ulrik Søchting, and Patrik Frödén. The generic name Calogaya honours Dr. Ester Gaya, a Spanish botanist from the University of Barcelona.
Flavoplaca is a genus of crust-like or scaly lichens in the family Teloschistaceae. It has 28 species with a mostly Northern Hemisphere distribution.
Squamulea is a genus of lichen-forming fungi in the family Teloschistaceae. It has 15 species. The genus was circumscribed in 2013 by Ulf Arup, Ulrik Søchting, and Patrik Frödén, with Squamulea subsoluta assigned as the type species. Five species were included in the original account of the genus. The genus name alludes to the squamulose growth form of most of its species. Squamulea has a worldwide distribution; when the genus was originally created, the centre of distribution was thought to be in southwestern North America.
Brownliella is a genus of crustose lichens in the subfamily Teloschistoideae of the family Teloschistaceae. It has two species. The genus was circumscribed in 2013 by Sergey Kondratyuk, Ingvar Kärnefelt, John Elix, Arne Thell, and Jae-Seoun Hur, with the widely distributed lichen Brownliella aequata assigned as the type species. The genus contains species formerly referred to as the Caloplaca cinnabarina species group. The generic name honours Australian botanist Sue Brownlie.
Filsoniana is a genus of squamulose lichens in the family Teloschistaceae. It has six species. It was circumscribed in 2013 by Ingvar Kärnefelt, Arne Thell, Jae-Seoun Hur, Sergey Kondratyuk, and John Elix following a molecular phylogenetic analysis of the Teloschistaceae. The generic name honours Australian lichenologist Rex Filson, "in recognition of his contribution to lichenology, in particular to the lichen flora of Australia".
Huneckia is a genus of crustose lichens in the subfamily Caloplacoideae of the family Teloschistaceae. It has four species.
Neobrownliella is a genus of crustose lichens in the subfamily Teloschistoideae of the family Teloschistaceae. It has five species. The genus was circumscribed in 2015 by lichenologists Sergey Kondratyuk, Jack Elix, Ingvar Kärnefelt, and Arne Thell, with Neobrownliella brownlieae assigned as the type species. It is a segregate of the large genus Caloplaca. Characteristics of Neobrownliella include a thallus that is continuous or areolate, the presence of anthraquinones as lichen products, a cortical layer with a palisade paraplectenchyma, and the lack of a thick palisade cortical layer on the underside of the thalline exciple. Two species were included in the original circumscription of the genus; an additional three species were added in 2020.
Wetmoreana is a genus of lichen-forming fungi in the family Teloschistaceae. It comprises 15 formally described species, one subspecies, and three undescribed species of crustose or squamulose that are predominantly saxicolous (rock-dwelling). The genus is characterized by its distinct lobes, orange zeorine apothecia when present, and the frequent occurrence of asexual propagules such as schizidia, isidia, or soredia. A key diagnostic feature is the presence of calcium oxalate crystals in the thallus medulla of many species.
Tassiloa is a genus of lichen-forming fungi in the family Teloschistaceae. It has two species.
Rusavskia is a genus of lichen-forming fungi in the family Teloschistaceae. It has 12 species. It is a member of the subfamily Xanthorioideae. The thallus of Rusavskia is characterized by its foliose (leaf-like) structure with distinct and typically narrow lobes that curve outwards.
Marchantiana is a genus of lichen-forming fungi in the family Teloschistaceae. It contains seven species of corticolous (bark-dwelling), crustose lichens that occur in the Southern Hemisphere.
Orientophila is a genus of lichen-forming fungi in the family Teloschistaceae. It has 15 species of mostly saxicolous (rock-dwelling), crustose lichens. All Orientophila species occur in Northeast Asia including China, Japan, South Korea, and the Russian Far East.
Caloplaca sipmanii is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. Found in Queensland, Australia, it was formally described as a new species in 2009 by the lichenologists Sergey Kondratyuk, Ingvar Kärnefelt, John Elix, and Jan Vondrák. The type specimen was collected by the third author from Baga National Park at an elevation of 50 to 150 m, where it was found growing on Eucalyptus bark. The species epithet of this lichen pays homage to the Dutch lichenologist Harrie Sipman, in whose honour the volume featuring this species was dedicated. Caloplaca sipmanii contains lichexanthone as a major lichen product.
Xanthocarpia jerramungupensis is a species of terricolous (ground-dwelling), crustose lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2009 by lichenologists Sergey Kondratyuk, Ingvar Kärnefelt, and John Elix; they classified it in the genus Caloplaca. The type specimen was collected from Jerramungup, Western Australia, where it was found growing among scrub on sandy soil. The species epithet refers to the type locality, which, at the time of its original publication, was the only known location of this lichen. Kondratyuk and colleagues transferred the taxon to the genus Xanthocarpia in 2013, as part of comprehensive molecular phylogenetics-led restructuring of the Teloschistaceae.
Franwilsia bastowii is a species of ramicolous (twig-dwelling), crustose lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2009 by lichenologists Sergey Kondratyuk and Ingvar Kärnefelt. It was transferred to the genus Franwilsia in 2014. The species epithet bastowii honours the Scottish naturalist Richard Austin Bastow, who collected the type specimen in Mornington in 1901. The lichen is known to occur in Western Australia, South Australia, and Victoria, where it grows on the twigs of various shrubs and trees.
Eilifdahlia dahlii is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. Widely distributed in Southern Australia, it was formally described as a new species in 2009 by John Elix, Sergey Kondratyuk, and Ingvar Kärnefelt. The type specimen was collected by the first author in 1990 from Mountain Creek in Jimberoo State Forest, where it was found growing on a dead Callitris on a rocky ridge dominated by that tree. It has also been recorded growing on the branch and twig bark of Casuarina stricta, and species of Eucalyptus, Leptospermum, and Melaleuca. The species epithet dahlii honours the Norwegian lichenologist Eilif Dahl, "for his significant contribution to Australian lichenology". The taxon was transferred to Eilifdahlia in 2014, a newly circumscribed genus in which it is the type species.
