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".

Amandinea clandestinus is a species of crustose lichen in the family Caliciaceae, and found in New South Wales. It was first described in 2013 by Australian lichenologists Jack Elix and Gintaras Kantvilas from a specimen collected on coastal rocks at Jervis Bay, New South Wales.
Amandinea devilliersiana is a species of crustose lichen in the family Caliciaceae, and found in South Australia. It was first described in 2013 by Australian lichenologists Jack Elix and Gintaras Kantvilas from a specimen collected on a granite boulder near the seashore in South Australia. The species epithet, devilliersiana, honours Brigitte de Villiers. Specimens used for the description came from both Tasmania and South Australia.
Pannaria aotearoana is a species of lichen in the family Pannariaceae, first described in 2016 by Arve Elvebakk and John Elix from a specimen found on a Coprosma linariifolia in the South Island of New Zealand.
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.
Buellia magaliesbergensis is a species of crustose lichen in the family Caliciaceae. Found in South Africa, it was formally described as a new species in 2021 by lichenologists John Alan Elix and Helmut Mayrhofer. The type specimen was collected in the Magaliesberg Range, at an altitude of 1,720 m (5,640 ft). Here the saxicolous lichen was found growing on rocks on the ground. The species epithet refers to the type locality, which is the only location where the lichen has been documented. The results of standard chemical spot tests are: thallus K+ (yellow), P+ (yellow-orange), and C−. Buellia magaliesbergensis contains norstictic acid as a major secondary chemical, and connorstictic acid as a minor compound.
Buellia subeffigurata is a species of crustose lichen in the family Caliciaceae. Found in South Africa, it was formally described as a new species in 2021 by John Alan Elix, Helmut Mayrhofer, and Wolfgang Wetschnig. The type specimen was collected in the Knersvlakte, at an altitude of 150 m (490 ft). Here the saxicolous lichen was found growing on quartziferous rock. The species epithet refers to its subeffigurate marginal lobes. The results of standard chemical spot tests are: thallus K+ (yellow), P+ (yellow-orange), and C−. Buellia subeffigurata contains thiophanic acid as a major secondary chemical, and isoarthothelin and atranorin as minor compounds.
Buellia georgei is a species of lichen in the family Caliciaceae. Found in Australia, it was formally described as a new species in 2001 by lichenologists Ulrike Trinkaus, Helmut Mayrhofer, and John Elix. The type specimen was collected in Yanchep National Park ; here it was found growing on soft limestone. It has also been recorded from South Australia, New South Wales, and the Australian Capital Territory; preferred habitats are calcareous outcrops, on thin soil over limestone, or rarely on calcareous soil. The lichen produces some secondary compounds: arthothelin as a major metabolite, and minor amounts of 4,5-dichloronorlichexanthone and thiophanic acid. The specific epithet honours Western Australian botanist Alex George.
Buellia lobata is a species of terricolous (soil-dwelling) lichen in the family Caliciaceae. Found in Australia, it was formally described as a new species in 2001 by lichenologists Ulrike Trinkaus and John Elix. The type specimen was collected in Blanchetown ; here, in a parking area after the bridge, on the east side of the Murray River, the lichen was found growing on soil. It has also been recorded from Western Australia. The lichen occurs on calcareous soil in mallee, often with other terricolous lichens including species of Endocarpon, Toninia, Eremastriella crystallifera, Fulgensia bracteata, and Psora decipiens. Secondary compounds that occur in the lichen include arthothelin and thuringione as major components, and minor amounts of 4,5-dichloronorlichexanthone and thiophanic acid. The species epithet lobata refers to the distinct lobes that comprise the thallus.
Buellia capensis is a species of crustose lichen in the family Caliciaceae. Found in South Africa, it was formally described as new species in 2021 by John Elix and Helmut Mayrhofer. The type specimen was collected south of Langebaan at an altitude ranging from 80 to 130 m ; here it was found growing on granite from a south-exposed slope. It is only known from the type collection. The contains several secondary compounds, including lichexanthone and secalonic acid A as major metabolites, and trace amounts of fumarprotocetraric acid and succinprotocetraric acid. The specific epithet capensis refers to the region of the type locality.
Xanthoparmelia semiviridis, also known as resurrection lichen is a foliose lichen species in the family Parmeliaceae. Its common name comes from the reaction of a dry sample to moisture. In its dry state it appears like curled-up dry leaf litter on the ground, but after rainfall the lichen will quickly recover, unfurl and become darker in colour. It is found in semi-arid areas across southern Australia and the South Island of New Zealand. The species is in decline in New Zealand because of the loss of habitat resulting from the establishment of dairy farms and vineyards in former indigenous habitat, and the deterioration of existing habitat caused by invasive species such as hawkweeds.
Thelenellaceae is a family of lichen-forming fungi. It is the sole family in the monotypic order Thelenellales, and contains three genera and about 50 species.
