The Pannariaceae are a family of lichens in the order Peltigerales. Species from this family have a widespread distribution, but are especially prevalent in southern temperate regions.
Acanthothecis is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909.
Psoroma is a genus of lichen-forming fungi in the family Pannariaceae. The widespread genus contains about 30 species, most of which are found in south temperate regions.
Protopannaria is a genus of seven species of lichenized fungi in the family Pannariaceae. The genus was originally circumscribed as a subgenus of the genus Pannaria by Hungarian lichenologist Vilmos Kőfaragó-Gyelnik. Per Magnus Jørgensen and Stefan Ekman promoted Protopannaria to full status as a genus in 2000.
Pannaria is a genus of lichen-forming fungi in the family Pannariaceae. The widespread genus contains an estimated 51 species, found primarily in tropical regions.
Fuscopannaria is a genus of lichen-forming fungi in the family Pannariaceae. It has 55 species.
Fuscoderma is a genus of lichenized fungi in the family Pannariaceae. It was originally circumscribed as a subgenus of the genus Leioderma by David Galloway and Per Magnus Jørgensen in 1987. The same authors promoted it to generic status a couple of years later in 1989. The New Guinean species F. papuanum was added to the genus in 2002.
Erioderma is a genus of lichen-forming fungi in the family Pannariaceae. They are commonly called mouse ears or felt lichens, and are small, pale brown to olive-brown foliose cyanolichens with a fuzzy upper surface that have the cyanobacteria Scytonema as their photobiont. Most species are found in the tropics of Central and South America, although three species are found in coastal regions of North America where they generally grow on mossy branches in humid sites. All North American species are rare. Species of Erioderma can resemble Pannaria, Leioderma, or small Peltigera, but their fuzzy upper surface and lack of veins on their lower surface distinguishes them from these lichens.
Degelia is a genus of lichen-forming fungi in the family Pannariaceae. The genus is named after Swedish lichenologist Gunnar Degelius.
Porina is a genus of lichens in the family Trichotheliaceae. A 2020 estimate places about 145 species in the widespread genus.
Anisomeridium is a genus of lichens in the family Monoblastiaceae. The type species was originally named Arthopyrenia xylogena by Swiss botanist Johannes Müller Argoviensis in 1883; in 1928, Maurice Choisy defined the genus Anisomeridium, designating A. xylogena the type species.
Leptogium is a genus of lichen-forming fungi in the family Collemataceae. It has about 110 species. Species formerly classified under Leptogium have since been divided among the genera Leptogium, Pseudoleptogium, and Scytinium. Leptogium lichens are predominantly found on tree bark or soil, often among mosses, and sometimes on rocks in moist environments.
Staurolemma is a genus of lichenized fungi in the family Pannariaceae. The genus was circumscribed by German lichenologist Gustav Wilhelm Körber in 1867, with Staurolemma dalmaticum as the type species.
Phlyctis is a genus of lichenized fungi in the order Gyalectales, and the type genus of the family Phlyctidaceae. Members of the genus are commonly called blemished lichens.
Lepidocollema is a genus of lichens in the family Pannariaceae. It was circumscribed in 1890 to contain a single Brazilian species that has not been collected since. In 2016, the entire family was revised and updated, resulting in the expansion of Lepidocollema to 24 tropical species.
Lepidocollema wainioi is a species of lichen in the family Pannariaceae. It is known from southeast Asia.
Vahliella is a genus of nine species of lichen-forming fungi in the order Peltigerales. It is the only member of Vahliellaceae, a family circumscribed in 2010 to contain this genus. Vahliella was formerly placed in the family Pannariaceae until molecular phylogenetics showed that it did not belong there. Vahliella species are found in the Northern Hemisphere – mainly in North America, but also in Europe and India.
Per Magnus Jørgensen is a Norwegian botanist and lichenologist, and Professor Emeritus of systematic botany at the University of Bergen. He is known for his work on the lichen families Pannariaceae and Collemataceae. Jørgensen was awarded the Acharius Medal in 2021 for his lifetime contributions to lichenology.
Degelia neozelandica is a species of foliose lichen in the genus Degelia.
