The Pertusariaceae are a family of lichen-forming fungi in the order Pertusariales.
Psoroma is a genus of lichenized fungi in the family Pannariaceae. The genus was circumscribed by French botanist André Michaux in 1803. The widespread genus contains an estimated 58 species, most of which are found in south temperate regions. Some species formerly in Psoroma were transferred to the new genera Psorophorus and Xanthopsoroma in 2010. The genus Joergensenia was erected in 2008 to contain the species formerly known as Psoroma cephalodinum.
Menegazzia nothofagi is a species of lichen from New Zealand and Australia. It was originally named as a species of Parmelia by Austrian botanist Alexander Zahlbruckner in 1940.
Harry Howard Barton Allan was a New Zealand teacher, botanist, and writer. Despite never receiving a formal education in botany, he became an eminent scientist, publishing over 100 scientific papers, three introductory handbooks on New Zealand plants, and completing the first volume of a flora in his lifetime.
Parmotrema araucariarum is a species of lichen in the family Parmeliaceae. It was first described scientifically as a species of Parmelia by Austrian botanist Alexander Zahlbruckner in 1909. Mason Hale transferred it to the genus Parmotrema in 1974. The lichen has been reported from Kenya, Tanzania, and South America.
Helge Thorsten Lumbsch is a German-born lichenologist living in the United States. His research interests include the phylogeny, taxonomy, and phylogeography of lichen-forming fungi; lichen diversity; lichen chemistry and chemotaxonomy. He is the Associate Curator and Head of Cryptogams and Chair of the Department of Botany at the Field Museum of Natural History.
Alan W. Archer is a mycologist. He is currently an honorary research associate at Royal Botanic Gardens Sydney, and working on the chemotaxonomy of the lichen genus Pertusaria together with a key to all taxa in that genus.
Pertusaria ambigua is a lichen in the family Pertusariaceae, and found in New South Wales, growing on trees.
Gunnar Bror Fritiof Degelius was a Swedish lichenologist. Between the publications of his first and final scientific papers, Degelius had a 70-year-long research career. While he was best known for his expertise on the lichen genus Collema, he also wrote important papers on lichen biology and ecology, floristic studies of the Nordic countries and various other areas around the world, and lichen succession. Degelius described 124 new taxa, and published about 130 scientific papers. In 1992 he was one of the first to be awarded the Acharius Medal for his lifetime contributions to lichenology. Fifteen species and three genera have been named in honour of Degelius.
Melanohalea ushuaiensis is a species of lichen in the family Parmeliaceae. It was first formally described in 1917 by Alexander Zahlbruckner as Parmelia ushuaiensis. Ted Esslinger transferred to the new genus Melanelia in 1978, which he circumscribed to contain the brown parmeliae species. In 2004, it was moved to the newly created genus Melanohalea. It is endemic to South America.
Clathroporina wainiana is a species of crustose lichen in the family Trichotheliaceae. It was formally described as a new species in 1902 by German lichenologist Alexander Zahlbruckner. The type was collected by Franz Xaver Rudolf von Höhnel in the Rio de Janeiro Botanical Garden. The species epithet honours Finnish lichenologist Edvard August Vainio.
Pertusaria aptrootii is a species of crustose lichen in the family Pertusariaceae. It was described as a new species in 1998 by Alan W. Archer and John Alan Elix. The lichen occurs in Papua New Guinea, and is known from only two specimens collected at the type locality. The type was collected in Varirata National Park at an altitude of 800 m (2,600 ft), where it was found growing on conglomerate rock. It is named after Dutch lichenologist André Aptroot, who collected the type.
Glyphis cicatricosa is a crustose lichen in the family Graphidaceae. It has a pantropical distribution, being found in the US, Central and South America, South, South-East and East Asia, Australia, New Zealand and the Pacific.
Salazinic acid is a depsidone with a lactone ring. It is found in some lichens, and is especially prevalent in Parmotrema and Bulbothrix, where its presence or absence is often used to help classify species in those genera.
Pertusaria salazinica is a species of crustose lichen in the family Pertusariaceae. Found in Australia, it was described as a new species in 2017 by lichenologists Alan Archer and John Alan Elix. The type specimen was collected in Tully Gorge National Park (Queensland) at an altitude of 885 m (2,904 ft). Here, in a montane rainforest, it was found growing on a rotting log. The specific epithet refers to the presence of salazinic acid, a major secondary compound in the lichen. It also contains norstictic acid as a major metabolite, and connorstictic acid as a minor metabolite. Pertusaria salazinica is only known from the type specimen.
Pertusaria lichexanthoimmersa is a rare species of crustose and corticolous (bark-dwelling) lichen in the family Pertusariaceae. Found in Bahia, Brazil, it was formally described as a new species in 2018 by lichenologists André Aptroot and Marcela Eugenia da Silva Cáceres. The type specimen was collected by the authors from the Morro do Pai Inácio at an altitude between 1,050 and 1,140 m ; here the lichen was found growing on tree bark in a transitional forest. Pertusaria lichexanthoimmersa is only known to occur at the type locality, and is only known from the type specimen. The specific epithet lichexanthoimmersa refers both to the presence of lichexanthone as a secondary chemical, and the apothecia, which are immersed in the thallus. The lichen also contains norstictic acid.
Pertusaria lichexanthoverrucosa is a rare species of crustose and corticolous (bark-dwelling) lichen in the family Pertusariaceae. Found in Bahia, Brazil, it was formally described as a new species in 2018 by lichenologists André Aptroot and Marcela Eugenia da Silva Cáceres. The type specimen was collected by the authors near the Cachoeira do Mosquito at an altitude between 450 and 500 m ; here the lichen was found growing on tree bark in Atlantic Forest near a river. Pertusaria lichexanthoverrucosa is only known to occur at the type locality, which is part of the Chapada Diamantina mountains. The specific epithet lichexanthoverrucosa refers to both the presence of lichexanthone as well as the verrucose (warty) thallus.
Pseudocyphellaria allanii is a species of corticolous (bark-dwelling) and foliose (leafy) lichen in the family Lobariaceae. Found in New Zealand, it was formally described as a new species in 1982 by Bernd Renner and David Galloway. The type specimen was collected by Galloway on the path to Emily Falls on Mount Peel ; here it was found growing on a fallen Pseudowintera on a stream bank. The lichen contains the secondary compounds 7β-acetoxyhopan-22-ol and hopan-15α-22-diol, which are derivatives of the triterpene compound hopane. The specific epithet allanii honours New Zealand botanist Harry Allan, who "described the vegetation of Mt Peel, and who later promoted interest in New Zealand lichens".
Caloplaca allanii is a species of saxicolous (rock-dwelling) and crustose lichen in the family Teloschistaceae. Found in New Zealand, it was formally described as a new species by Alexander Zahlbruckner. The type specimen was collected by Lucy Cranwell on Anawhata Beach in 1932; she sent a dried specimen to Zahlbruckner for identification. The specific epithet allanii honours New Zealand botanist Harry Allan.
