The Physciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. A 2016 estimate placed 19 genera and 601 species in the family.
Platygramme is a genus of lichen-forming fungi in the family Graphidaceae consisting of about 30 species. The genus was circumscribed by Antoine Laurent Apollinaire Fée in 1874.
Septotrapelia is a genus of lichen-forming fungi in the family Pilocarpaceae. It has four species. It was validly published as a genus in 2007 by lichenologists André Aptroot and Jose-Luis Chaves.
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.
Gassicurtia is a genus of lichenized fungi in the family Caliciaceae.
Dirinaria is a genus of lichenized fungi in the family Caliciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 35 species.
Diploicia is a genus of lichenized fungi in the family Caliciaceae. The genus has a widespread distribution, especially in temperate regions, and contains 6 species.
Pyxine is a genus of foliose lichens in the family Caliciaceae. The genus has a widespread distribution in tropical regions.
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.
Vainionora is a genus of lichen in the family Lecanoraceae. The genus, which was circumscribed in 1991 by German lichenologist Klaus Kalb, honours the Finnish lichenologist Edvard Vainio, who described the type species as Lecanora pallidostraminea in 1890.
Traponora is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed in 2009 by Dutch lichenologist André Aptroot, with the Papua New Guinean Traponora asterella assigned as the type, and at that time, only species. Four newly described species were added to the genus in a 2009 publication, a species formerly in Pyrrhospora was transferred to the genus in 2017, and a new species from Australia added in 2018. Traponora lichens are predominantly from Australasia, with all species but one known to occur in Papua New Guinea.
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 36 genera and about 600 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.
Caliciales is an order of mostly lichenized fungi in the class Lecanoromycetes. It consists of two families: Caliciaceae and Physciaceae, which together contain 54 genera and more than 1200 species. The order was circumscribed by American botanist Charles Edwin Bessey in 1907.
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.
Polyblastidium is a genus of foliose lichens in the family Physciaceae. It has 18 species. The genus was circumscribed by German lichenologist Klaus Kalb in 2015, with Polyblastidium japonicum assigned as the type species. Polyblastidium is similar in morphology to Heterodermia, but its lower surface is cobweb-like in structure (arachnoid), and its ascospores are mostly 1-septate with 1 to 3 sporoblastidia. It is this latter feature that is referenced in the genus name Polyblastidium. The genus contains several species that were formerly classified in the genus Anaptychia.
Leucodermia is a genus of lichen-forming fungi in the family Physciaceae.
Klaus Kalb is a German lichenologist and an authority on tropical lichens.
Halegrapha is a genus of lichen-forming fungi in the family Graphidaceae. It has nine species. The genus was circumscribed in 2011 by Eimy Rivas Plata and Robert Lücking, with Halegrapha chimaera assigned as the type species. The generic name honors American lichenologist Mason Hale.
