The type species was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park. Here it was found growing on a branch of the tree Pinus contorta in muskeg. The specific epithet muskeg is an Algonquin word for a blanket bog.
Parmelia barrenoae is a species of foliose lichen in the large family Parmeliaceae. It was formally described as a new species in 2005. Before this, it was lumped together as one of several lichens in the Parmelia sulcata group—a species complex of genetically distinct lookalikes. Parmelia barrenoae is widely distributed, occurring in Europe, western North America, Africa, and Asia.
Buellia sulphurica is a species of saxicolous (rock-dwelling), crustose lichen in the family Caliciaceae. Found in the Galápagos Islands, it was described as new to science in 2011 by Frank Bungartz and André Aptroot. The type specimen was collected on the northern exposed inner caldera rim of the Alcedo Volcano on Isabela Island at an altitude of 1,055 m (3,461 ft). Here, near the sulphur vents, it was found growing on basalt rock; nearby vegetation included Adianthus concinnum and Tournefortia rufosericea. It has additionally been recorded on the Chico volcano, also on Isabela Island. The specific epithet sulphurica alludes to both the bright yellow colour of the thallus, and the proximity of the lichen to sulphur vents. Buellia sulphurica contains rhizocarpic acid, a secondary compound that is rare in genus Buellia.
Lecanora panticapaensis is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecanoraceae. It occurs in a single locality in Dnipropetrovsk Oblast, Ukraine, where it grows on the vertical surfaces of black schist beside a river.
Lecania sessilisoraliata is a species of saxicolous (rock-dwelling), crustose lichen in the family Ramalinaceae. It is found on rock outcrops in the mountainous Burdur region of Turkey.
Lecanora lojkahugoi is a species of saxicolous (rock-dwelling) crustose lichen in the family Lecanoraceae. It is found in the Russian Far East and in South Korea.
Pertusaria pseudoparotica is a species of saxicolous (rock-dwelling), crustose lichen in the family Pertusariaceae. It is known from a few localities in Greece's Aegean Islands.
Dirina catalinariae is a species of saxicolous (rock-dwelling), crustose lichen in the family Roccellaceae. It occurs in the southwestern United States, Mexico, and the Galápagos Islands.
Dirina canariensis is a species of saxicolous (rock-dwelling), crustose lichen in the family Roccellaceae. It is found in the Canary Islands, where it grows on vertical cliffs and acidic rocks. It was formally described as a new species in 2013 by lichenologists Anders Tehler and Damien Ertz. The type specimen was collected by the first author from the Puerto de Mogán ; the species epithet refers to the type locality. The lichen has a creamy-white to brownish-white thallus, a chalk-like medulla, and either soralia or apothecia on the thallus surface. If apothecia are present, they have a circular outline with a diameter of up to 1.5 mm; the discs are pruinose and encircled by a thalline margin. Ascospores measure 20–25 by 4–5 μm. The closest relatives of Dirina canariensis are the European species D. ceratoniae, D. massiliensis, and D. fallax.
Dirina fallax is a species of saxicolous (rock-dwelling), crustose lichen in the family Roccellaceae. It is found in the western Mediterranean, the Atlantic coasts of both Africa and Europe, and central Europe, where it grows on siliceous and acidic rocks. In 2017, it was reported from the Abrau Peninsula in Russia.
Lecanora compallens is a species of corticolous (bark-dwelling) crustose lichen in the family Lecanoraceae. Found in Asia and Europe, it was formally described as a new species in 1999 by lichenologists Kok van Herk and André Aptroot. The type specimen was collected by the first author from Drouwenerveen (Drenthe), where it was found growing on the bark of Quercus robur. The species epithet compallens is derived from the Latin com and (ex)pallens, alluding to the typical occurrence of the morphologically similar Lecanora expallens at the same location.
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".
Dirina mexicana is a species of saxicolous (rock-dwelling), crustose lichen in the family Roccellaceae. First identified in Mexico, it displays distinctive characteristics which set it apart from other species within the same genus. The lichen is unique for its varied hues and certain chemical characteristics that are seen in its thallus, or vegetative tissue. Typically growing on vertical or overhanging rocks and cliffs, Dirina mexicana can be found in specific regions across Mexico.
Enterographa kinabaluensis is a species of corticolous (bark-dwelling) crustose lichen in the family Ramalinaceae. Found in coastal rainforests on the island of Borneo, it was described as a new species in 2020. Characterised by its white thallus, punctiform (dot-like) soralia and norstictic acid content, this lichen is readily recognisable when fertile.
Fulvophyton serusiauxii is a species of saxicolous (rock-dwelling) crustose lichen in the family Roccellographaceae. It has a distinct cream-coloured, areolate thallus and specific chemical characteristics. This lichen is only known from its type locality in Mexico where it grows on granite boulders near the Pacific Ocean shore.
