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.
Santessoniella is a genus of lichenized fungi in the family Pannariaceae. The classification reflects various changes made based on the Systema Ascomycetum and Myconet in the Deep Hypha issue of Mycologia.
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.
Fuscopannaria is a genus of lichen-forming fungi in the family Pannariaceae. It has 55 species.
Degelia is a genus of lichen-forming fungi in the family Pannariaceae. The genus is named after Swedish lichenologist Gunnar Degelius.
Gyalecta is a genus of lichen-forming fungi in the family Gyalectaceae that contains 50 species. Gyalecta was circumscribed by lichenologist Erik Acharius in 1808.
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.
Porpidia is a genus of crustose lichens in the family Lecideaceae.
Arctomia is a genus of lichen-forming fungi in the family Arctomiaceae. The genus was originally circumscribed by Theodor Magnus Fries in 1861. Arctomia has a circumpolar distribution.
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.
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.
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.
Lepidocollema marianum is a species of cyanolichen in the family Pannariaceae. It was first scientifically described by Elias Fries in 1825 as Parmelia mariana. Per Magnus Jørgensen transferred it to the genus Lepidocollema in 2014 following a molecular phylogenetics-guided revision of the Pannariaceae.
Degelia neozelandica is a species of foliose lichen in the genus Degelia.
Rostania is a genus of lichen-forming fungi in the family Collemataceae. These lichens are primarily found on tree bark, occasionally on wood, with one species known to inhabit soil. The genus is characterized morphologically by having minute thalli made of hyphal tissue without a separate cortex, and the more or less cuboid-shaped ascospores.
