Ochrolechia is a genus of crustose lichens in the family Ochrolechiaceae.
Corticifraga is a genus of lichenicolous fungi in the family Gomphillaceae. The genus was circumscribed by David Leslie Hawksworth and Rolf Santesson in 1990, with Corticifraga peltigerae assigned as the type species.
Toensbergia is a genus of lichen-forming fungi in the family Sporastatiaceae. The genus was circumscribed by Mika Bendiksby and Einar Timdal in 2013. The genus name honours Norwegian lichenologist Tor Tønsberg, "in appreciation of his important work on sorediate, corticolous lichens". The type species is Toensbergia leucococca, which was formerly classified in genus Hypocenomyce, presumably due to its resemblance to Hypocenomyce xanthococca.
Atrophysma is a fungal genus in the family Pannariaceae. It contains the single species Atrophysma cyanomelanos, a crustose lichen found only in Alaska.
Porpidia seakensis is a species of crustose lichen in the family Lecideaceae. It is an endolithic species, meaning it grows inside the rocks, between the grains. Found only in Alaska, it was formally described as a new species in 2020 by British lichenologist Alan Fryday. The type specimen was collected in the Hoonah-Angoon Census Area, in Glacier Bay National Park. Here it was discovered growing on granitic rock in a woodland. The lichen is only known from this area, although it is locally common. Its preferred habitat is siliceous rocks and boulders in wooded areas that are open and well lit. The specific epithet seakensis uses the letters "seak" to refer to a standard abbreviation for southeast Alaska.
Fuscidea muskeg is a species of crustose lichen in the family Fuscideaceae. Found in Alaska, it was described as a new species in 2020 by Tor Tønsberg and Martina Zahradníková. 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.
Fuscopannaria dillmaniae is a species of lichen in the family Pannariaceae. Found in Alaska, it was described as a new species in 2020 by lichenologist Toby Spribille.
Lambiella aliphatica is a species of crustose lichen in the family Xylographaceae. Found in Alaska, it was described as a new species in 2020 by Toby Spribille and Philipp Resl. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park. Here it was found at an altitude of 907 m (2,976 ft) growing on an argillite rock in alpine scree. The specific epithet aliphatica refers to the unidentified fatty acids that are present in the thallus. It is the first member of genus Lambiella to contain primarily fatty acids in the thallus. Lambiella globulosa is similar in morphology, but this species contains stictic acid rather than fatty acids as the primary secondary metabolite.
Lecania hydrophobica is a species of crustose lichen in the family Ramalinaceae. Found in Alaska, it was described as a new species in 2020 by Toby Spribille and Alan Fryday. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park. Here it was found at an altitude of 9 m (30 ft) growing on a vertical shale outcrop. The specific epithet hydrophobic refers to the hydrophobic (water-repelling) properties of the lichen, which are possibly imparted by the wax-like filaments on the surface of the apothecial disc. Lecania hydrophobica is abundant on sheltered rock overhangs in the type locality, and is also known to occur further south – on southern Baranof Island, and in British Columbia.
Spilonema maritimum is a species of lichen in the family Coccocarpiaceae. Found in Alaska, it was described as a new species in 2020 by lichenologists Toby Spribille and Alan Fryday. The type specimen was collected in Juneau Borough, on the west side of Douglas Island. Here it was found growing on exposed seashore rocks roughly 2 m (6.6 ft) above the high tide line. Its specific epithet maritimum alludes to its close association with maritime rocks.
Miriquidica gyrizans is a species of lichen-forming fungus in the family Lecanoraceae. It is found in Alaska and the Yukon, where it grows on granitic boulders.
Lecanora viridipruinosa is a species of crustose lichen in the family Lecanoraceae. Found in Alaska, it was formally described as a new species by lichenologists Måns Svensson and Toby Spribille. The type specimen was collected from the Hoonah-Angoon Census Area in Glacier Bay National Park. Here it was found growing on exposed argillite rock in an alpine heath at an elevation of 920 m (3,020 ft). The specific epithet viridipruinosa refers to the greenish pruina on the discs of the apothecia. The lichen is only known to occur in the type locality.
Placynthium glaciale is a species of saxicolous lichen in the family Placynthiaceae. Found in Alaska, it was described as a new species in 2020 by lichenologists Alan Fryday and Toby Spribille. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park, on the upper end of Muir Inlet. Here the lichen was found growing on an argillite-like boulder as well as exposed cobbles in post-glacial soil. The specific epithet glaciale alludes to its association with glacial forelands.
Sagiolechia phaeospora is a species of crustose lichen in the family Sagiolechiaceae. It is found in the alpine tundra of Alaska.
Lecidea griseomarginata is a species of lichen in the family Lecideaceae. Found in Alaska, it was described as a new species in 2020 by lichenologist Alan Fryday. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park, where it was found growing on a granitic rock along the shoreline of Ptarmigan Creek. It is only known to occur at the type locality. The specific epithet griseomarginata refers to the gray proper margin of the apothecia.
Lecidea streveleri is a species of crustose lichen in the family Lecideaceae. Found in Canada and the United States, it was described as a new species in 2020 by lichenologist Toby Spribille. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park (Alaska). Here it was on steep slopes in a basin on the west side of Dundas Bay, growing on the bark of an alder tree. The specific epithet streveleri honors Dr. Gregory P. Streveler, who, according to Spribille, is "an extraordinary naturalist and polymath, and author of numerous scientific papers, who has dedicated much of his life to understanding the natural history of Glacier Bay".
Toensbergia blastidiata is a species of crustose lichen in the family Sporastatiaceae. Found in northwestern North America, it was described as a new species in 2020 by lichenologists Toby Spribille and Tor Tønsberg. The type specimen was collected in Glacier Bay National Park at the base of Marble Mountain (Alaska). Here the lichen was found growing on the bark of Alnus viridis subsp. crispa. The specific epithet blastidiata refers to the "blastidiate thallus surface"; blastidia are vegetative propagules containing both mycobiont and photobiont, which are produced by yeast-like "budding".
Thelocarpon immersum is a species of lichen in the family Thelocarpaceae. Found in Alaska, it was described as a new species in 2020 by lichenologist Alan Fryday. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park. Here the lichen was found near the park entrance growing on soil in a calcareous wet meadow in a glacial outwash plain. The specific epithet immersum refers to the perithecioid ascomata, which are immersed in "a mat of cyanobacteria and chlorococcoid algae, with only the tips protruding". The lichen is only known from the type locality.
Steineropsis laceratula is a species of crustose placodioid lichen in the family Pannariaceae. It was first formally described in 1902 by French lichenologist Auguste-Marie Hue as Pannaria laceratula. Per Magnus Jørgensen proposed a transfer to Fuscopannaria in 1994. The taxon shuffled genera again in 2020 by Toby Spribille and Stefan Ekman after molecular phylogenetic analysis of the DNA from specimens collected in Alaska revealed its correct classification in the genus Steineropsis. The type specimen was collected in 1904 from Hakkoda, Japan, at an elevation of 1,200 m (3,900 ft); here the lichen was found growing on the bark of birch, but the species also grows on rock.
Ochrolechia minuta is a species of crustose lichen in the family Ochrolechiaceae. It was first formally described in 1938 by Swedish lichenologist Gunnar Degelius as Perforaria minuta. The type specimen was collected from the Kodiak Island Borough in Alaska. Toby Spribille transferred it to the genus Ochrolechia in 2020, suggesting that the absence of cephalodia, and the presence of alectoronic acid, indicate that it is "related to the alectoronic acid-containing species of poriform Ochrolechia".
