Lichinales is the sole order of ascomycete fungi in the class Lichinomycetes. It contains three families: Gloeoheppiaceae, Lichinaceae, and Peltulaceae. Most species are lichenized. Lichinales was proposed in 1986 by German lichenologists Aino Henssen and Burkhard Büdel. The class Lichinomycetes was created by Valérie Reeb, François Lutzoni and Claude Roux in 2004.
Gloeoheppiaceae is a family of ascomycete fungi in the order Lichinales. The family contains ten species distributed amongst three genera. Most species are lichenised with cyanobacteria. Species in this family are mostly found in desert areas. Modern molecular phylogenetics analysis casts doubt on the phylogenetic validity of the family, suggesting a more appropriate placement of its species in the family Lichinaceae.
The Lichinaceae are a family of ascomycete fungi. Most species are lichenized with cyanobacteria, and have a distribution largely in temperate regions.
Mazosia is a genus of lichen-forming fungi in the family Roccellaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1854.
Lempholemma is a genus of lichen-forming fungi in the family Lichinaceae.
Lichinella is a genus of lichen-forming fungi in the family Lichinaceae. It was circumscribed in 1872 by Finnish lichenologist William Nylander. Five species are accepted by Species Fungorum.
Peccania is a genus of lichenized fungi within the family Lichinaceae. As of July 2023, Species Fungorum accepts five species of Peccania, although many more species have been placed in the genus.
Psorotichia is a genus of lichen-forming fungi in the family Lichinaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1855, with Psorotichia murorum assigned as the type species.
Pterygiopsis is a genus of fungi within the family Lichinaceae. It contains 11 species.
Stromatella bermudana is a saxicolous (rock-dwelling) crustose lichen. It is the only species in Stromatella, a monotypic fungal genus in the family Lichinaceae. The genus was circumscribed in 1989 by German lichenologist Aino Henssen. This species was originally described as Psorotichia bermudana by US botanist Lincoln Ware Riddle in 1916, from specimens collected in Bermuda.
Zahlbrucknerella is a genus of filamentous, rock-dwelling lichens in the family Lichinaceae.
Peltula is a genus of small dark brown to olive or dark grey squamulose lichens. These lichens typically grow on rocks in arid and semi-arid environments worldwide. They consist of a fungus living in symbiosis with a photosynthetic partner, specifically a cyanobacterium of the genus Chroococcidiopsis. Peltula is the only genus in the family Peltulaceae, which belongs to the Lichinomycetes, a class of fungi that form lichens. The genus includes about 50 recognised species, which exhibit a variety of growth forms ranging from flat and crust-like to more complex, leaf-like structures. Peltula lichens play important ecological roles in harsh environments, contributing to soil stability and nutrient cycling.
Sagiolechia is a genus of lichen-forming fungi in the family Sagiolechiaceae. The genus was circumscribed by lichenologist Abramo Bartolommeo Massalongo in 1854, who assigned Sagiolechia protuberans as the type species. The family Sagiolechiaceae was proposed in 2010 to contain Sagiolechia as the type genus, and genus Rhexophiale; molecular phylogenetic analysis showed that these two genera formed a distinct clade in the Ostropales.
Heppia is a genus of olive, brownish, gray, or blackish squamulose, crustose, or peltate like lichens. Heppia was once the type genus of the family Heppiaceae, but that family was folded into synonymy with Lichinaceae.
Massalongia is a genus of lichen-forming fungi in the family Massalongiaceae. It has four species. The genus was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855, with M. carnosa assigned as the type species.
Sporastatia is a genus of crustose lichens in the family Sporastatiaceae. It has four species. Sporastatia lichens are long-lived species that grow on siliceous or weakly calcareous rocks in arctic and alpine locales.
Harpidiaceae is a small family of lichen-forming fungi, containing two genera and five species. It is of uncertain classification in the Pezizomycotina.
Blastodesmia is a monotypic fungal genus in the family Pyrenulaceae. It contains the single species Blastodesmia nitida, a corticolous (bark-dwelling) crustose lichen found in Europe. Both the genus and the species were described in 1852 by the Italian botanist Abramo Bartolommeo Massalongo. Historically, two other species have been included in the genus, but are currently not accepted by Species Fungorum:
Pseudoheppia is a fungal genus in the family Lichinaceae. It contains a single species, Pseudoheppia schuleri, a saxicolous (rock-dwelling) squamulose lichen.
Metamelanea is a small genus of lichen-forming fungi in the family Lichinaceae. It consists of three species of rock-dwelling lichens.
