Schismatomma is a genus of mostly lichen-forming fungi in the family Roccellaceae. [1]
Schismatomma leucopsarum was assessed as a Critically Endangered species in 2023 for the IUCN Red List. The lichen is known from only a single location in the municipality of Honda, Cundinamarca Department, where it is threatened by deforestation for timber extraction and expansion of industrial areas. Despite surveys in similar habitats, the species has not been rediscovered since its initial collection. [2]
As of July 2024 [update] , Species Fungorum (in the Catalogue of Life) accepts seven species of Schismatomma, [3] although many more than this have been named.
The Roccellaceae are a family of mostly lichen-forming fungi in the order Arthoniales, established by the French botanist François Fulgis Chevallier in 1826. Species in the family exhibit various growth forms, including crustose and fruticose (shrub-like) thalli, and diverse reproductive structures. Roccellaceae species typically have disc-like or slit-like fruiting bodies, often with distinct blackened margins. Molecular phylogenetics studies have revealed considerable genetic diversity and complex evolutionary histories within the family.
Sarcographa is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by theFrench botanist Antoine Laurent Apollinaire Fée in 1825.
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.
Chiodecton is a genus of lichens in the family Roccellaceae. The genus was circumscribed by the lichenologist Erik Acharius in 1814, with Chiodecton sphaerale assigned as the type species.
Ancistrosporella is a genus of lichen-forming fungi in the family Roccellaceae. The genus was circumscribed in 1995 by Swedish lichenologist Göran Thor, with Ancistrosporella australiensis assigned as the type species. The International Union for Conservation of Nature has classified A. leucophila as a Critically Endangered species due to its limited known distribution in South America and the threats to its habitat from deforestation and land-use changes.
Enterographa is a genus of lichens in the family Roccellaceae.
Opegrapha is a genus of lichenized fungi in the family Opegraphaceae.
Lecanographa is a genus of about 40 species of lichens in the family Lecanographaceae. It was circumscribed in 1994 by José M. Egea and Pilar Torrente, with Lecanographa lyncea as the type species.
Lecanactis is a genus of crustose lichens, commonly called old wood rimmed lichen. The genus was circumscribed in 1855 by German lichenologist Gustav Wilhelm Körber, who assigned Lecanactis abietina as the type species.
Merismatium is a genus of lichenicolous (lichen-dwelling) fungi of uncertain familial placement in the order Verrucariales. The genus was circumscribed in 1898 by Friedrich Wilhelm Zopf.
Arthopyrenia is a genus of fungi in the family Trypetheliaceae. It was formerly classified in the eponymic family Arthopyreniaceae, but molecular phylogenetics studies showed that the type species, Arthopyrenia cerasi, was a member of the Trypetheliaceae.
Synarthonia is a genus of lichen-forming fungi in the order Arthoniales. The genus has not been placed into a family. Synarthonia was circumscribed by Swiss lichenologist Johannes Müller Argoviensis in 1891.
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.
Vigneronia is a genus of lichen-forming fungi in the family Roccellaceae. It has five species. The genus was circumscribed in 2014 by Damien Ernst, with Vigneronia spieri assigned as the type species. This species, originally described as Schismatomma spieri from collections made in the Galápagos Islands, has since been recorded from mainland Ecuador and the Antilles (Curaçao). The genus is named after Ernst's wife, Nathalie Vigneron, who accompanied him on collecting trips.
Fouragea is a genus of lichen-forming fungi in the family Opegraphaceae. It has nine species.
Fulvophyton is a genus of lichen-forming fungi in the family Roccellographaceae. It has 11 species. Fulvophyton is characterised by its crust-like thallus, which is often pale yellowish-brown in colour. This genus features a photobiont from the green algal genus Trentepohlia and exhibits a unique arrangement of reproductive structures.
Phacographa is a genus of lichenicolous (lichen-dwelling) fungi in the family Roccellaceae. It has three species.
Snippocia is a monospecific fungal genus in the family Arthoniaceae. It contains the single species Snippocia nivea, a crustose, corticolous (bark-dwelling) lichen. This lichen was previously known as Schismatomma niveum; Snippocia was established to accommodate the species after molecular studies indicated that it did not belong in its previously assigned genus.
