The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Vainionora is a genus of lichen in the family Lecanoraceae. The genus, which was circumscribed in 1991 by German lichenologist Klaus Kalb, honours the Finnish lichenologist Edvard Vainio, who described the type species as Lecanora pallidostraminea in 1890.
Candelariella is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with Candelariella vitellina assigned as the type species.
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.
Lecanora printzenii is a species of crustose lichen in the family Lecanoraceae. Originally found in Spain, it was described as new to science in 2011. It shares several characteristics with lichens of the Lecanora varia group but is differentiated by its unique sequence in the internal transcribed spacer (ITS) region of its DNA and by several distinctive physical characteristics.
Lecanora strobilina, also known as the mealy rim lichen, is a species of crustose lichen in the family Lecanoraceae. It was originally described as Parmelia strobilina by German botanist Kurt Polycarp Joachim Sprengel in 1827. It is distributed across North America and the Mediterranean but has become established in South America and the Galapagos. It can be distinguished from other closely-related species in the genus by the presence of the polyphenolic compound decarboxysquamatic acid in thin-layer chromatography (TLC).
Palicella is a genus of crustose lichens in the family Lecanoraceae. It contains six species.
Lecanora solaris is a species of crustose lichen in the family Lecanoraceae. Found in the Altai Mountains in Russia, the lichen was described as new to science in 2019 by Lydia Yakovchenko and Evgeny Davydov. The lichen is similar in general morphology to Lecanora somervellii, but can be distinguished from that species by its small, squamulose (scaly) to marginally lobate umbilicate thallus and the persistent margin of its apothecia. The species epithet makes reference to the bright yellow colour of the lichen.
Lecanora kohu is a species of lichen in the family Lecanoraceae. Found in the Chatham Islands of New Zealand, it was formally described as new to science in 2017.
Lecanora kalbii is a species of crustose lichen in the family Lecanoraceae. Found in the Galápagos Islands, it was described as a new species in 2020 by lichenologists Frank Bungartz and John Alan Elix. The specific epithet kalbii honours German lichenologist Klaus Kalb.
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.
Lendemeriella aureopruinosa is a species of crustose lichen in the family Teloschistaceae. Found in the Russian Far East, it was formally described as a new species in 2021 by Ivan Frolov, Jan Vondrák, Ulf Arup, Liudmila Konoreva, and Sergey Chesnokov, Lidia Yakovchenko, and Evgeny Davydov. The type specimen was collected on the banks of River Bes-Yuryakh ; here it was found growing on siliceous outcrops in a forest comprising largely birch, alder, and larch trees. The thallus of the lichen ranges in form from an inconspicuous grey film to a more well-developed crust or areoles. Its apothecia measure 0.3–0.6 mm in diameter and have a dark-orange to brick-red coloured disc. Secondary chemicals detected in the lichen include parietin, parietinic acid, emodin, teloschistin, and fallacinal. The specific epithet aureopruinosa refers to the bright gold-coloured pruina that is found on young apothecia.
Lecanora helmutii is a rare species of corticolous (bark-dwelling), crustose lichen in the family Lecanoraceae. Found in Tasmania, it was formally described as a new species in 2018 by Sergio Pérez-Ortega and Gintaras Kantvilas. The type specimen was collected from the eastern side of Stanley Highway, where it was found growing on the bark of Banksia marginata in a coastal swampy woodland dominated by Melaleuca. It is only known from the type collection. Other associated lichens include Austroparmelina pseudorelicina, Bactropsora paludicola, Menegazzia subpertusa, Pannaria elixii, and Parmotrema perlatum. The species epithet honours Austrian lichenologist Helmut Mayrhofer.
Lacrima is a genus of lichen-forming fungi in the family Teloschistaceae. It has four saxicolous (rock-dwelling), crustose species.
Fauriea is a genus of lichen-forming fungi in the family Teloschistaceae. The genus, which contains seven species, is a member of the subfamily Caloplacoideae.
Glaucomaria is a genus of lichen-forming fungi in the family Lecanoraceae. It has seven species. The genus was circumscribed by Maurice Choisy in 1929. It contains crustose lichens formerly placed in the Lecanora rupicola species complex as defined by several previous authors.
Sucioplaca is a single-species fungal genus in the family Teloschistaceae. It contains Sucioplaca diplacia, a saxicolous (rock-dwelling) crustose lichen. It is common and widely distributed in the Caribbean, Central America, and the Galápagos Islands, where it grows on coastal rocks.
Porpidinia is a genus of lichen-forming fungi in the family Lecideaceae. It has two species of saxicolous (rock-dwelling) lichens. The type species of the genus, Porpidinia tumidula, thrives in a variety of settings from coastal to mountainous areas, primarily on lime-rich rocks, and is widely spread across southern to northern Europe, northern Africa, parts of Asia, and New Zealand. Meanwhile, Porpidinia brevispora is more regionally confined, found specifically in the Sikhote-Alin range in the Russian Far East, favouring carbonate rocks at lower altitudes.
Lecanora perpruinosa is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecanoraceae. It occurs in Northern Europe, Estonia, Turkey, Russia, and Canada, where it grows on calcareous rocks.
