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.
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.
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.
Amandinea is a genus of lichenized fungi in the family Caliciaceae. Genetic studies indicates that the genus Amandinea and Buellia are the same, although this is not widely accepted.
Diploicia is a genus of lichenized fungi in the family Caliciaceae. The genus has a widespread distribution, especially in temperate regions, and contains 6 species.
Dimelaena is a genus of rimose to areolate placoidioid crustose lichens. It is in the family Caliciaceae. Members of the genus are commonly called mountain lichens, or moonglow lichens. The genus has a widespread distribution and contains eight species.
Tetramelas is a genus of lichenized fungi in the family Caliciaceae.
Opegrapha is a genus of lichenized fungi in the family Opegraphaceae. Species include:
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 36 genera and about 600 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.
Mycoblastus is a genus of crustose lichens in the family Tephromelataceae. Members of the genus are commonly called blood lichens.
Josef Hafellner is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a Professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus Karschia. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae has been described as "probably the single most influential publication in lichen systematics in the latter half of the 20th century".
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.
Sculptolumina is a genus of corticolous lichens in the family Caliciaceae. The genus was circumscribed by Bernhard Marbach in 2000, with Sculptolumina japonica designated as the type species.
Endohyalina is a genus of 10 species of corticolous lichens in the family Caliciaceae. The genus was circumscribed by Bernhard Marbach in 2000, with Endohyalina rappii designated as the type species.
Helmut Mayrhofer is an Austrian lichenologist. He is known for his expertise on the lichen family Physciaceae and his studies of the lichen flora of the Balkan Peninsula, the Alps, and other regions.
Halecania is a genus of fungi in the family Leprocaulaceae. It has 22 species. The genus was circumscribed by Austrian lichenologist Michaela Mayrhofer in 1987, with Halecania alpivaga assigned as the type species. She created Halecania to contain species, formerly placed in Lecania, with the following characteristics: uniformly amyloid apical domes, paraphyses with dark brown apical caps, and halonate ascospores.
Dufourea is a genus of mostly foliose lichen species in the subfamily Xanthorioideae of the family Teloschistaceae. Species in the genus are found in the Southern Hemisphere.
Henricus (Harrie) Johannes Maria Sipman is a Dutch lichenologist. He specialises in tropical and subtropical lichens, and has authored or co-authored more than 250 scientific publications. He was the curator of the lichen herbarium at the Berlin Botanical Garden and Botanical Museum from 1983 until his retirement in 2010.
