Gassicurtia is a genus of lichenized fungi in the family Caliciaceae. [1]
The genus was circumscribed by French botanist Antoine Laurent Apollinaire Fée in Essai Crypt. Exot. (Paris) 1: XLVI, 100 in 1825. [2]
The genus name of Gassicurtia is in honour of Louis Claude Cadet de Gassicourt (1731–1799) who was a French chemist who synthesised the first organometalic compound. [3]
It was later resurrected by Bernhard Marbach in his 2000 monograph on Buellia sensu lato. The genus contains species that are part of the tropical Buellia group with 2-celled ascospores, and which lack algae in the margin. [4]
As of January 2024 [update] , Species Fungorum accepts 36 species in the genus Gassicurtia:
Diorygma is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Franz Gerhard Eschweiler in 1824. Species of the genus are widely distributed in tropical and subtropical regions of the world.
Carbacanthographis is a genus of corticolous (bark-dwelling) lichens in the family Graphidaceae. The genus was circumscribed by German lichenologists Bettina Staiger and Klaus Kalb in 2002. An updated worldwide key to the genus was published in 2022 that added 17 new species.
Acanthothecis is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909.
Porina is a genus of lichens in the family Trichotheliaceae. A 2020 estimate places about 145 species in the widespread genus.
Fellhanera is a genus of mostly leaf-dwelling lichens in the family Pilocarpaceae. The genus, circumscribed by lichenologist Antonín Vězda in 1986, honours Austrian lichenologist Josef Hafellner.
Micarea is a genus of lichenized fungi in the family Pilocarpaceae. The widely distributed genus contains 126 species and new species are described actively. Species in the genus are crustose lichens and their photobiont is a single-celled green alga.
Cratiria is a genus of lichen-forming fungi in the family Caliciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 20 species. The genus was circumscribed by Austrian lichenologist Bernhard Marbach in 2000, with Cratiria lauri-cassiae assigned as the type species.
Amandinea is a genus of lichenized fungi in the family Caliciaceae. Genetic studies indicates that the genus Amandinea and Buellia are the same, although this is not widely accepted.
Cryptothecia is a genus of white to greenish crustose lichens that grow on bark, wood, or leaves, in tropical or subtropical areas worldwide. It has a conspicuous prothallus that develops around its periphery which can be bright red in some species, hence the common name wreath lichen. The main vegetative body (thallus) lacks a cortex (ecorticate and is often immersed in the substrate or byssoid. The medulla is white, well defined, and often peppered with calcium oxalate crystals. Ascomata are not well defined, being cushions of soft white mycelium immersed in the medullary tissue, hence the name from the Greek krypto = "to conceal" and theke = "a container or sheath". It contains Trentepohlia, a green alga, as its photobiont partner.
Cresponea is a genus of lichens in the family Roccellaceae. The genus, circumscribed in 1993, contains species that were formerly classified in Lecanactis. Cresponea is widely distributed, but most species are found in tropical and subtropical regions. The genus is named in honor of Spanish lichenologist Ana Crespo.
Lecidella is a genus of crustose lichens in the family Lecanoraceae.
Ramboldia is a genus of lichen-forming fungi in the family Ramboldiaceae. The genus was circumscribed in 1994 by Gintaras Kantvilas and John Alan Elix. It was emended in 2008 by the inclusion of Pyrrhospora species containing the anthraquinone russulone in their apothecia and having a prosoplectenchymatous exciple. The family Ramboldiaceae was circumscribed in 2014 to contain the genus.
Echinoplaca is a genus of lichens in the family Gomphillaceae.
Megalaria is a genus of lichen-forming fungi in the family Ramalinaceae. The genus was circumscribed by Austrian lichenologist Josef Hafellner in 1984, with Megalaria grossa assigned as the type species.
Malmidea is a genus of crustose lichens and the type genus of the family Malmideaceae. It was established in 2011 to contain a phylogenetically distinct group of species formerly placed in the genus Malcolmiella. The crust-like thallus of Malmidea lichens has a surface that varies from smooth to rough, featuring textures such as verrucose (wart-like), granulose (grainy), or pustulate (pimpled). These textures are often formed by goniocysts, which are spherical clusters of green algal cells from the family Chlorococcaceae, encased in fungal hyphae. Malmidea comprises nearly 70 mostly tropical species that grow on bark, although a few grow on leaves.
Baculifera is a genus of lichens in the family Caliciaceae. It was circumscribed in 2000 by Bernhard Marbach and Klaus Kalb. Species in this genus are characterized by having bacilliform conidia typically measuring 8–11 μm long, and a non-inspersed hymenium. The genus is roughly similar in morphology to Buellia.
Myriostigma is a genus of lichens in the family Arthoniaceae. The genus was circumscribed by German lichenologist August von Krempelhuber in 1874.
