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.
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.
Anaptychia is a genus of lichen-forming fungi in the family Physciaceae.
Heterodermia is a genus of lichenized fungi in the family Physciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 80 species.
Gassicurtia is a genus of lichenized fungi in the family Caliciaceae.
Pyxine is a genus of foliose lichens in the family Caliciaceae. The genus has a widespread distribution in tropical regions.
Bulbothrix is a genus of lichen-forming fungi in the family Parmeliaceae. This genus is synonymous with Bulbothricella V.Marcano, S.Mohali & A.Morales. Bulbothrix was circumscribed by lichenologist Mason E. Hale in 1974 with Bulbothrix semilunata as the type species.
Relicina is a genus of foliose lichens belonging to the large family Parmeliaceae. It contains 59 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.
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. Malmidea comprises more than 50 mostly tropical species that grow on bark, although a few grow on leaves.
Orcularia is a genus of four species of lichens in the family Caliciaceae. It was originally circumscribed as a section of the genus Rinodina by Swedish botanist Gustaf Oskar Andersson Malme in 1902. Klaus Kalb and Mireia Giralt promoted it to generic status in 2011. Orcularia is characterized by the presence of ascospores that develop in such a way that the septum is inserted after lateral wall thickenings become distinct, and also by threadlike (filiform) conidia.
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.
Eugeniella is a genus of mostly leaf-dwelling (foliicolous) lichens in the family Pilocarpaceae. It contains 13 species. The genus was circumscribed in 2008 by lichenologists Robert Lücking, Emmanuël Sérusiaux, and Klaus Kalb, with Eugeniella psychotriae assigned as the type species. This lichen was originally called Patellaria psychotriae by Johannes Müller Argoviensis in 1881. The seven species that were initially included in the genus had previously been placed in the genera Bacidia and Byssoloma. Several newly identified species from Australasia and Central and South America were later added. Most of the species grow on leaves, although four of the Australasian species grow on bark.
Leucodermia is a genus of lichen-forming fungi in the family Physciaceae.
Loxospora is a genus of lichen-forming fungi in the family Sarrameanaceae. It has 13 species. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852, with Loxospora elatina assigned as the type species. This crustose lichen was originally named Lecanora elatina by Erik Acharius in 1810.
Klaus Kalb is a German lichenologist and an authority on tropical lichens.
Myriostigma is a genus of lichens in the family Arthoniaceae. The genus was circumscribed by German lichenologist August von Krempelhuber in 1874.
Klauskalbia is a genus of lichen-forming fungi in the family Physciaceae. It has four species of foliose lichens.
