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.
Metus is a genus of three species of lichenized fungi in the family Cladoniaceae. The genus was circumscribed by lichenologists David John Galloway and Peter Wilfred James in 1987, with Metus conglomeratus as the type species. All three species are found in the Southern Hemisphere.
Stirtoniella is a lichen genus in the family Ramalinaceae. It is a monotypic genus, containing the single species Stirtoniella kelica, a crustose and corticolous lichen originally described from New Zealand in 1873 as a species of Lecidea. The photobiont is an alga of the family Chlorococcaceae. The genus is named after Scottish mycologist James Stirton.
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.
Parmeliella is a genus of lichenized fungi in the family Pannariaceae. It occurs mainly in the tropics and sub-tropics, with species found in Africa, Asia, Australasia and South America. A recent (2020) estimate places 41 species in the genus.
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.
Leioderma is a genus of lichen-forming fungi in the family Pannariaceae. The genus was circumscribed by the Finnish lichenologist William Nylander in 1888. He assigned Leioderma pycnophorum as the type species.
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.
Candelaria is a genus of lichen-forming fungi in the family Candelariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852.
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.
Leciophysma is a genus of cyanolichens in the family Pannariaceae. It has four species. The genus was circumscribed by Theodor Magnus Fries in 1865, with Leciophysma finmarkicum assigned as the type species.
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.
Degelia plumbea is a species of grey to blue-black or brown foliose lichen in the genus Degelia. It mostly grows on trees in undisturbed woodlands but occasionally on coastal rocks. It is found widely in Britain and western Ireland as well as in America and Canada, as it grows in maritime Atlantic climates.
Degelia cyanoloma is a species of blue-grey to lead-grey foliose lichen in the genus Degelia. It mostly grows on mossy trees in undisturbed woodlands. It is found in the Scottish Highlands, western Ireland and Norway, as it grows in maritime Atlantic climates.
Gunnar Bror Fritiof Degelius was a Swedish lichenologist. Between the publications of his first and final scientific papers, Degelius had a 70-year-long research career. While he was best known for his expertise on the lichen genus Collema, he also wrote important papers on lichen biology and ecology, floristic studies of the Nordic countries and various other areas around the world, and lichen succession. Degelius described 124 new taxa, and published about 130 scientific papers. In 1992 he was one of the first to be awarded the Acharius Medal for his lifetime contributions to lichenology. Fifteen species and three genera have been named in honour of Degelius.
Placolecis is a genus of lichen-forming fungi in the family Catillariaceae. It has four species of saxicolous (rock-dwelling) and crustose lichens. The genus was circumscribed by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1857. He did not assign a type species for the genus. Josef Hafellner designated a lectotype for Placolecis balanina in 1984, but subsequently, this taxon was folded into P. opaca.
Degelia neozelandica is a species of foliose lichen in the genus Degelia.
Austroparmeliella is a genus of lichen-forming fungi in the family Pannariaceae. It consists of five species, all of which are found in the Southern Hemisphere.
