Leptotrema is a genus of lichen-forming fungi in the family Graphidaceae. [1] The genus was circumscribed in 1856 by Camille Montagne and Roelof Benjamin van den Bosch, with Leptotrema zollingeri assigned as the type species. [2]
As of March 2023 [update] , Species Fungorum (in the Catalogue of Life) accepts 15 species of Leptotrema. [1]
Bacidia is a genus of lichen-forming fungi in the family Ramalinaceae. The genus was circumscribed by Giuseppe De Notaris in 1846. Species in the genus are crust-like lichens with stemless apothecia; they have green algae (chloroccoid) as photobionts. Their asci have 8 colorless, cylindrical to acicular, multiseptate spores, with curved and thread-like conidia.
Phaeographis is a genus of lichen-forming fungi in the family Graphidaceae. It has an estimated 180 species.
Lecania is a genus of lichenized fungi in the family Ramalinaceae. The genus was circumscribed by Abramo Bartolommeo Massalongo in 1853. Lecania is widely distributed, especially in temperate regions, and contains about 64 species.
Porina is a genus of lichens in the family Trichotheliaceae. A 2020 estimate places about 145 species in the widespread genus.
Clathroporina is a genus of lichenized fungi in the family Trichotheliaceae. It was circumscribed by Swiss lichenologist Johannes Müller Argoviensis in 1882.
Diploschistes is a genus of lichen-forming fungi in the family Graphidaceae. Members of the genus are crustose lichens with a thick, cracked (areolate) body (thallus) with worldwide distribution. The fruiting part (apothecia) are immersed in the thick thallus so as to have the appearance of being small "craters". The widespread genus contains about 43 species.
Thelotrema is a genus of lichen-forming fungi in the family Graphidaceae, the family to which all taxa in the former Thelotremataceae now belong.
Phaeotrema is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 1887 by Johannes Müller Argoviensis, with P. subfarinosum assigned as the type species.
Huea is a genus of lichenized fungi in the family Lecanoraceae. It was circumscribed by Carroll William Dodge and Gladys Elizabeth Baker in 1938.
Chiodecton is a genus of lichens in the family Roccellaceae. The genus was circumscribed by lichenologist Erik Acharius in 1814, with Chiodecton sphaerale assigned as the type species.
Arthopyrenia is a genus of fungi within the Arthopyreniaceae family. The genus has a widespread distribution, a cosmopolitan distribution. It formerly contained about 117 species.
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.
Melaspilea is a genus of lichen-forming and lichenicolous fungi in the family Melaspileaceae. The genus was circumscribed by Finnish lichenologist William Nylander in 1857.
Graphina is a genus of script lichens in the family Graphidaceae. It has about 25 species. The genus was circumscribed in 1880 by Swiss lichenologist Johannes Müller Argoviensis. Müller Argoviensis did not indicate a type species for the genus in his original publication; David Hawksworth proposed to designate Graphina anguina as a lectotype in 1981.
Pseudosagedia is a genus of corticolous (bark-dwelling) lichens in the family Trichotheliaceae. It was first circumscribed as a section of genus Arthopyrenia by Swiss botanist Johannes Müller Argoviensis in 1862. Maurice Choisy elevated it to distinct generic status in 1949. Pseudosagedia was little used until, in 1995, Josef Hafellner and Klaus Kalb resurrected the genus to contain members of the Porina nitidula species group with the perithecial pigment called Pseudosagedia-violet and lacking setae.
