Cladia is a genus of lichenized fungi in the family Cladoniaceae. Cladia species have a crustose primary thallus and a fruticose, secondary thallus, often referred to as pseudopodetium. The type species of the genus, Cladia aggregata, is widely distributed, occurring from South America, South Africa, Australasia and South-East Asia to southern Japan and India. Most of the other species are found in the Southern Hemisphere.
Cratiria is a genus of lichenized fungi in the family Caliciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 20 species. The genus was circumscribed by Austrian lichenologist Bernhard Marbach in 2000, with Cratiria lauri-cassiae assigned as the type species.
Enterographa is a genus of lichens in the family Roccellaceae.
Lecidella is a genus of crustose lichens in the family Lecanoraceae.
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.
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.
John Alan (Jack) Elix emeritus professor in chemistry at the Australian National University, is an organic chemist who has contributed in many fields: lichenology, lichen chemotaxonomy, plant physiology and biodiversity and natural product chemistry. He has authored 2282 species names, and 67 genera in the field of mycology.
Pertusaria ambigua is a lichen in the family Pertusariaceae, and found in New South Wales, growing on trees.
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.
Punctelia pseudocoralloidea is a species of foliose lichen in the family Parmeliaceae. It is found in Australia, where it grows on bark and on wood.
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.
Menegazzia fortuita is a species of foliose lichen in the family Parmeliaceae. Found in Australia, it was described as a new species in 2017 by lichenologists John Elix and Patrick McCarthy. The type specimen was collected in Morton National Park where it was found in an open rocky ridge growing on sandstone. The specific epithet fortuita refers to its discovery: "an unplanned field-stop that led to the discovery of the most recent collection which, fortuitously, helped to resolve the identity of several older, unnamed specimens". The lichen is known to occur only in a few locations in Morton National Park where it grows on sandstone in open Eucalyptus woodland. The expected results for standard chemical spot tests are cortex K+ (yellow); medulla K+ (yellow), C−, KC−; P+ (yellow-orange). Menegazzia fortuita contains several secondary chemicals: stictic acid as a major component, atranorin and constictic acid as minor components, and trace amounts of peristictic acid, cryptostictic acid, and menegazziaic acid.
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.
Catillaria gerroana is a species of crustose lichen in the family Catillariaceae. Found in Australia, it was described as a new species in 2017 by lichenologists Patrick McCarthy and John Elix. The type specimen was collected in Black Head Reserve, where it was found growing on sandstone cliffs of the intertidal zone. The specific epithet refers to the type locality, which is the only location that this lichen is known to occur.
Xanthoparmelia metastrigosa is a lichen which belongs to the Xanthoparmelia genus. It is found only in Australia. It is one of the few lichens that is listed as endangered.
Xanthoparmelia canobolasensis is a lichen which belongs to the Xanthoparmelia genus. It is found in the Australian states of New South Wales and Tasmania. Although not currently endangered it appears to fulfill the criteria under the Tasmanian Threatened Species Protection Act 1995.
