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.
Lepra is a genus of lichen-forming fungi in the family Pertusariaceae. Although the genus was created in 1777, it was not regularly used until it was resurrected in 2016 following molecular phylogenetic analyses. It has more than a hundred species, most of which were previously classified in genus Pertusaria.
Pertusaria sipmanii is a species of crustose lichen in the family Pertusariaceae. Found in Papua New Guinea, it was formally described as a new species in 1998 by Alan Archer and John Elix. The species epithet sipmanii honours Dutch lichenologist Harrie Sipman, who collected the type specimen.
Pertusaria galapagoensis is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Elix, Yánez-Ayabaca, A.W.Archer & Bungartz. The type specimen was collected on Floreana Island at an altitude of 371 m (1,217 ft), where it was found growing on the bark of a south-exposed trunk of Cedrella odorata. The species epithet refers to its distribution.
Pertusaria albineoides is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, A.W.Archer, Alba Yánez-Ayabaca, and John Elix. The type specimen was collected on Alcedo Volcano at an altitude of 1,089 m (3,573 ft), where it was found growing on a partially shaded, rain- and wind-exposed trunk of Scalesia microcephala. The species epithet refers to the similarity to the species Pertusaria albinea, from which it differs by having thin-walled ellipsoid-shaped ascospores that are longer and narrower.
Pertusaria cerroazulensis is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, Alan W. Archer, Alba Yánez-Ayabaca, and John Elix. The type specimen was collected from the Cerro Azul volcano at an altitude of 1,038 m (3,406 ft), where in a small, shaded woodland, it was growing on twigs of Psidium galapageium. The species epithet refers to the type locality.
Pertusaria darwiniana is a species of corticolous-lignicolous, crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Alba Yánez-Ayabaca and Frank Bungartz. The type specimen was collected on the Darwin volcano at an altitude of 860 m (2,820 ft), where it was found growing on twigs of Croton scouleri. The species epithet acknowledges the Charles Darwin Foundation, and its namesake, Charles Darwin.
Pertusaria lueckingii is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, Alan W. Archer, and John Elix. The type specimen was collected on Floreana Island, where it was found growing on the bark of a south-exposed trunk of Cedrella odorata. The species epithet honours German lichenogist Robert Lücking, "who first recognized this taxon as an independent species".
Pertusaria medullamarilla is a species of saxicolous (rock-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by lichenologists Alba Yánez-Ayabaca, Frank Bungartz, Alan W. Archer, and John Elix. The type specimen was collected on Pinzón Island, where it was found growing on basalt. The species epithet refers to its yellow-coloured medulla.
Pertusaria stictica is a species of corticolous and lignicolous, crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Fredy Nugra, Alan W. Archer, Frank Bungartz, and John Elix. The type specimen was collected at the border of the Galápagos National Park at an altitude of 471 m (1,545 ft), where in a secondary forest it was found growing on Psidium galapageium. The species epithet refers to stictic acid, a major metabolite in the lichen. It also contains trace amounts of constictic acid.
Pertusaria thioisidiata is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Alba Yánez-Ayabaca, Frank Bungartz, Alan W. Archer, and John Elix. The type specimen was collected on the Alcedo Volcano at an altitude of 1,146 m (3,760 ft); there, on a southeast-exposed slope about 100 m (330 ft) below the rim of the crater, it was found growing on basalt. The species epithet refers to the presence of both isidia and the substance thiophaninic acid. The variety Pertusaria thioisidiata var. isidiogyrophorica contains gyrophoric acid rather than thiophaninic acid.
Pertusaria xanthoisidiata is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Alan W. Archer, Frank Bungartz, and John Elix. The type specimen was collected on Pinta Island, where it was growing on an exposed trunk of Opuntia galapageia. The species epithet refers to the yellow-coloured isidia.
