Ptychographa is a genus of lichenized fungi in the family Xylographaceae. It is a monotypic genus, containing the single species Ptychographa xylographoides. Both the species and genus were described as new in 1874 by Finnish botanist William Nylander.
Glyphis is a genus of lichen-forming fungi in the family Graphidaceae. The genus has a widespread distribution, especially in tropical regions.
Pycnothelia is a genus of lichen-forming fungi in the family Cladoniaceae. Pycnothelia was promoted to generic status by French naturalist Léon Jean Marie Dufour in 1821; it was originally circumscribed by Erik Acharius in 1799 as a section of the now-defunct genus Cenomyce.
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.
Gassicurtia is a genus of lichenized fungi in the family Caliciaceae.
Norrlinia is a genus of two species of fungi in the family Verrucariaceae. The genus was circumscribed by Ferdinand Theissen and Hans Sydow in 1918. The genus name honours the Finnish botanist Johan Petter Norrlin. Both species are lichenicolous, meaning they parasitise lichens. The host of both fungi is the foliose genus Peltigera.
Peltula is a genus of small dark brown to olive or dark gray squamulose lichens that can be saxicolous ) or terricolous. Members of the genus are commonly called rock-olive lichens. They are cyanolichens, with the cyanobacterium photobiont from the genus Anacystis. They are umbilicate with flat to erect squamule lobes that attach from a central holdfast or cluster of rhizenes. Lichen spot tests are usually negative.
Phaeocalicium is a genus of fungi in the family Mycocaliciaceae. The genus was circumscribed in 1970 by German lichenologist Alexander Schmidt, with Phaeocalicium praecedens assigned as the type species.
Sphinctrina is a genus of lichenicolous fungi, usually not lichenized, in the family Sphinctrinaceae. Its species are most commonly parasitic on lichens of the genus Pertusaria.
Placynthium is a genus of lichen-forming fungi in the family Placynthiaceae. Members of this genus are commonly called blackthread lichens.
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 39 genera and about 670 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.
Dactylina is a genus of lichen-forming fungi in the family Parmeliaceae. The genus was circumscribed by Finnish botanist William Nylander in 1860, with Dactylina arctica assigned as the type species.
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.
Sculptolumina is a genus of corticolous lichens in the family Caliciaceae. The genus was circumscribed by Bernhard Marbach in 2000, with Sculptolumina japonica designated as the type species.
Endohyalina is a genus of 10 species of corticolous lichens in the family Caliciaceae. The genus was circumscribed by Bernhard Marbach in 2000, with Endohyalina rappii designated as the type species.
Chrismofulvea is a genus of lichen-forming fungi in the family Caliciaceae. The genus was circumscribed by Austrian lichenologist Bernhard Marbach in 2000, with Chrismofulvea dialyta assigned as the type species. It was one of several segregate genera proposed by Marbach in his 2000 revision of American species of Buellia.
Fluctua is a lichen genus in the family Caliciaceae. It is monotypic, containing the single crustose lichen species Fluctua megapotamica. The genus was circumscribed by Austrian lichenologist Bernhard Marbach in 2000. It was one of several segregate genera proposed by Marbach in his 2000 revision of American species of Buellia. The lichen is found in Brazil and Uruguay.
Leproplaca is a genus of lichen-forming fungi in the family Teloschistaceae. Its exhibits a leprose growth form, where the thallus consists primarily of asexual propagules called soredia.
