Gyalectales is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 5 families, 18 genera and about 550 species.
Trapelia is a genus of lichenized fungi in the family Trapeliaceae.
Sarcogyne is a genus of crustose lichens in the family Acarosporaceae. It was circumscribed by German botanist Julius von Flotow in 1850. A proposal has been put forth in 2021 to assign Sarcogyne clavus as the type species of the genus, "as it represents the original concept of Sarcogyne as having melanized lecideine apothecia without algae in the margin".
Ramboldia is a genus of lichen-forming fungi in the family Ramboldiaceae. The genus was circumscribed in 1994 by Gintaras Kantvilas and John Alan Elix. It was emended in 2008 by the inclusion of Pyrrhospora species containing the anthraquinone russulone in their apothecia and having a prosoplectenchymatous exciple. The family Ramboldiaceae was circumscribed in 2014 to contain the genus.
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.
Protoparmelia is a genus of lichenized fungi in the family Parmeliaceae. The genus has a widespread distribution, and contains 11 species. Protoparmelia was circumscribed by French lichenologist Maurice Choisy in 1929.
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.
Megalaria is a genus of lichen-forming fungi in the family Ramalinaceae. The genus was circumscribed by Austrian lichenologist Josef Hafellner in 1984, with Megalaria grossa assigned as the type species.
Gintaras Kantvilas is an Australian lichenologist, who earned his Ph.D in 1985 from the University of Tasmania with a thesis entitled Studies on Tasmanian rainforest lichens. He has authored over 432 species names, and 167 genera in the field of mycology.
Catillaria is a genus of crustose lichens in the family Catillariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852. It is the type genus of Catillariaceae, which was circumscribed by Austrian lichenologist Josef Hafellner in 1984.
Eugeniella is a genus of mostly leaf-dwelling (foliicolous) lichens in the family Pilocarpaceae. It contains 13 species. The genus was circumscribed in 2008 by lichenologists Robert Lücking, Emmanuël Sérusiaux, and Klaus Kalb, with Eugeniella psychotriae assigned as the type species. This lichen was originally called Patellaria psychotriae by Johannes Müller Argoviensis in 1881. The seven species that were initially included in the genus had previously been placed in the genera Bacidia and Byssoloma. Several newly identified species from Australasia and Central and South America were later added. Most of the species grow on leaves, although four of the Australasian species grow on bark.
Buellia quarryana is a species of crustose lichen in the family Caliciaceae. Found in southeastern Australia, it was described as a new species in 2020 by lichenologists John Elix and Patrick McCarthy. The type specimen was collected from Quarry Beach in East Gippsland (Victoria), where it was found growing on siliceous rocks along the seashore. The specific epithet refers to the type locality. It has also been found on the coast of southern New South Wales.
Sarcogyne maritima is a species of crustose lichen in the family Acarosporaceae. Found in Australia, it was described as a new species in 2017 by lichenologists John Elix and Patrick McCarthy. The type specimen was collected on Werri Beach, where it was found growing above the seashore on hard sandstone. It is only known to occur at this location. The specific epithet maritima alludes to its habitat on coastal rocks.
Ramboldia curvispora is a species of crustose lichen in the family Ramboldiaceae. Found in Australia, it was described as a new species in 2017 by lichenologists John Elix and Patrick McCarthy. The type specimen was collected from Callala Bay, where it was found on a vertical shale cliff subject to sea spray and surface runoff from the top of the cliff. The specific epithet refers to its characteristic curved ascospores. The lichen is only known to occur on the South Coast of New South Wales, where it grows on both hard and soft siliceous rocks.
Fellhanera robusta is a species of crustose lichen in the family Pilocarpaceae. Found in Australia, it was described as a new species in 2017 by lichenologists John Elix and Patrick McCarthy. The type specimen was collected from a vertical shale cliff in Callala Bay. This location receives sea spray as well as surface runoff from above, and maintains a diverse lichen flora that contrasts with the absence of lichens in the surrounding shore area.
Gyrographa is a genus of lichen-forming fungi in the family Roccellaceae. The genus was circumscribed in 2014 by Damien Ernst and Anders Tehler, with Gyrographa gyrocarpa assigned as the type species. This lichen, originally described by Julius von Flotow in 1825, was first placed in the genus Opegrapha. Species in the genus have a crustose thallus lacking a cortex, and a dark brown prothallus. The photobiont partner is trentepholioid. The hypothecium is thick and carbonised, and the ascospores lack a gelatinous sheath; these characteristics distinguish it from Opegrapha species. The genus name alludes to the gyrose ascomata of the type species.
Myeloconis is a genus of corticolous (bark-dwelling), crustose lichens in the family Porinaceae. It has four species. The genus was circumscribed in 1996 by Patrick M. McCarthy and John Elix, with M. fecunda assigned as the type species. The genus name, derived from the Greek myelos and konis ("dust"), refers to the powdery yellow-orange pigments in the medulla.
Myeloconis erumpens is a species of corticolous (bark-dwelling), crustose lichen in the family Porinaceae. It is found in Papua New Guinea, north-eastern Australia and New Caledonia. The lichen was formally described as a new species in 1996 by Patrick M. McCarthy and John Elix. The species epithet erumpens refers to the distinctive thallus of the lichen, which has exposed patches and "eruptions" of yellow medulla that are visible against the brownish thallus.
Myeloconis guyanensis is a species of corticolous (bark-dwelling), crustose lichen in the family Porinaceae. Found in the coastal lowlands of eastern Guyana, it was formally described as a new species in 1996 by Patrick M. McCarthy and John Elix. Characteristics of the lichen include the prominent verrucae on the perithecia, its yellow, erumpent medulla, and the variety of lichen products found in the medulla.
Myeloconis parva is a species of corticolous (bark-dwelling), crustose lichen in the family Porinaceae. Found in Amazonian Brazil, it was formally described as a new species in 1996 by Patrick M. McCarthy and John Elix.
