Tassiloa is a genus of lichen-forming fungi in the family Teloschistaceae. [1] It has two species. [2]
The genus was circumscribed in 2015 by lichenologists Sergey Kondratyuk, Ingvar Kärnefelt, Arne Thell, Elix and Jae-Seoun Hur. According to their molecular phylogenetic analysis, Tassiloa appears as a sister group to the genus Catenarina , in the subfamily Teloschistoideae of family Teloschistaceae. The genus name honours German lichenologist Tassilo Feuerer. [3]
Tassiloa is identifiable by its vibrant orange colouration. Its thallus can range from a crustose appearance to a more elevated, microfruticose form. The surface of the thallus may be either smooth or have a denser texture. This genus is further characterized by lobules that are reminiscent of terete (i.e., cylindrical or slightly tapering) isidia in structure. These lobules or isidia stand out predominantly and align vertically. When considering reproductive attributes, the apothecia of Tassiloa can be categorized as either zeorine or lecanorine . Its true exciple has a paraplectenchymatous tissue structure. In terms of chemistry, Tassiloa contains anthraquinones, notably those linked with the parietin chemosyndrome . [3]
Tassiloa digitaurea is found growing on rock surfaces, detritus, and even over other lichen species. These habitats are typically located within exposed outcrops amidst shrub vegetation and grasslands in coastal regions. Notably, while they are found in coastal areas, their habitats are not strictly maritime. T. wetmorei is parasitic (lichenicolous), targeting various host lichens found on non-calcareous rocks. [3]
Tassiloa species are native to both the American continents. T. digitaurea is identified in southern Patagonia. Meanwhile, T. wetmorei has been recorded in the Sonoran Desert located in southwestern North America. [3]
The taxon Tassiloa magellanica(Søchting & Sancho) S.Y.Kondr. (2019) is now known by its original name, Caloplaca magellanica . [4]
The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. 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. Collectively, the family has a cosmopolitan distribution, although members occur predominantly in subtropical and temperate regions. Although most members are lichens that either live on rock or on bark, about 40 species are lichenicolous fungi–meaning they live on other lichens.
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).
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.
Fulgogasparrea is a genus of crustose lichens in the subfamily Xanthorioideae of the family Teloschistaceae. It has five species. The genus was circumscribed in 2013, with Fulgogasparrea decipioides assigned as the type species; this lichen had originally been formally described as a species of Caloplaca, and then a couple of years later transferred to Wetmoreana. Six are credited with authorship of the genus: Sergey Kondratyuk, Jeong Min-hye, Ingvar Kärnefelt, John Alan Elix, Arne Thell, and Jae-Seoun Hur. The genus name alludes to the resemblance of the type species with both of the Teloschistaceae genera Fulgensia and Gasparrinia.
Brownliella is a genus of crustose lichens in the subfamily Brownlielloideae of the family Teloschistaceae. It has four 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.
Kaernefia is a genus of crustose lichens in the family Teloschistaceae. It has three species, found in Australia or South Africa.
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.
Gallowayella aphrodites is a species of corticolous (bark-dwelling), foliose (leafy) lichen in the family Teloschistaceae. It is found in the Mediterranean countries Greece, Cyprus, and Italy. Characteristics of the lichen include its small thallus, the disposition of the rhizines on the thallus undersurface, and the lack of vegetative propagules.
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.
Golubkovia is a single-species genus in the family Teloschistaceae. It contains the species Golubkovia trachyphylla, a crustose lichen. The genus was circumscribed in 2014 by Sergey Kondratyuk, Ingvar Kärnefelt, John Elix, Arne Thell, and Jae-Seoun Hur. The generic name honours Russian lichenologist Nina Golubkova (1932–2009), who, according to the authors, "made important contributions to lichenology in northern Eurasia".
Wetmoreana is a genus of lichen-forming fungi in the family Teloschistaceae. It has two crustose, saxicolous (rock-dwelling) species.
Gallowayella hasseana, the poplar sunburst lichen, is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. It occurs in North America.
Catenarina is a genus of lichen-forming fungi in the family Teloschistaceae consisting of three species. These crustose lichens are characterized by their reddish-brown pigmentation and the presence of the secondary compound 7-chlorocatenarin. The genus is found in the southernmost regions of the Southern Hemisphere, including Antarctica, southern Patagonia, and the Kerguelen Islands.

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.
Cerothallia yarraensis is a species of corticolous (bark-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, as Caloplaca yarraensis. Kondratyuk and colleagues transferred it to the genus Cerothallia in 2014.
