The Lichinaceae are a family of ascomycete fungi. Most species are lichenized with cyanobacteria, and have a distribution largely in temperate regions.
Placopsis is a genus of lichenized fungi in the family Trapeliaceae.
Acarospora is a genus of mostly lichen-forming fungi in the family Acarosporaceae. Most species in the genus are crustose lichens that grow on rocks in open and arid places all over the world. They may look like a cobblestone road or cracked up old paint, and are commonly called cobblestone lichens or cracked lichens. They usually grow on rock, but some grow on soil (terricolous) or on other lichens. Some species in the genus are fungi that live as parasites on other lichens. Acarospora is a widely distributed genus, with about 128 species according to a 2008 estimate.
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.
Dermatocarpon is a genus of lichens in the family Verrucariaceae.
Rhizoplaca is a genus of lichenized fungi in the family Lecanoraceae. Members of the genus are commonly called rimmed navel lichens because of their umbilicate growth form and lecanorine apothecia, also rock-posy lichen and rockbright.
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.
Pyrenopsis is a genus of lichen-forming fungi in the family Lichinaceae. It contains 12 species. The genus was circumscribed by the Finnish lichenologist William Nylander in 1858.
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.
Placynthium is a genus of lichen-forming fungi in the family Placynthiaceae. Members of this genus are commonly called blackthread lichens.
Rhizocarpon is a genus of crustose, saxicolous, lecideoid lichens in the family Rhizocarpaceae. The genus is common in arctic-alpine environments, but also occurs throughout temperate, subtropical, and even tropical regions. They are commonly known as map lichens because of the prothallus forming border-like bands between colonies in some species, like the common map lichen.
Arthopyrenia is a genus of fungi in the family Trypetheliaceae. It was formerly classified in the eponymic family Arthopyreniaceae, but molecular phylogenetics studies showed that the type species, Arthopyrenia cerasi, was a member of the Trypetheliaceae.
Blastenia is a genus of lichen-forming fungi in the family Teloschistaceae. The genus was circumscribed in 1852 by Abramo Bartolommeo Massalongo.
Scytinium is a genus of lichen-forming fungi in the family Collemataceae. It has 49 species. These lichens are typically found on basic rocks, soil, and trees, occasionally in association with mosses. Despite the morphological and ecological diversity within Scytinium, its species share similar ascospore features, such as shape and septation, as well as a small to medium-sized thallus with at least a partial cortex.
Strangospora is a genus of lichen-forming fungi. It is the only genus in the family Strangosporaceae, which itself is of uncertain taxonomic placement in the Ascomycota. It contains 10 species.
Peccania tiruncula is a species of saxicolous (rock-dwelling), squamulose to dwarf fruticose lichen in the family Lichinaceae. It was first described as a new species in 1878 by the Finnish lichenologist William Nylander, who classified it in the genus Omphalaria. The type specimen was collected by Johan Petter Norrlin in Biskra. Aino Henssen transferred it to the genus Peccania in 1990.
