Halecania athallina is a species of lichen in the family Leprocaulaceae. Found in Alaska, it was described as new to science in 2020 by British lichenologist Alan Fryday. The type specimen was discovered in Hoonah-Angoon Census Area in Glacier Bay National Park. There it was found growing on argillite rock on an alpine heath with rock outcrops. [1]

The thallus of this lichen is completely immersed in its substrate. The specific epithet athallina refers to this characteristic absence of a thallus. The lichen makes dark reddish-brown lecideine apothecia that are typically 0.3–0.4 mm in diameter. The ascospores are hyaline, have a single septum, and measure about 12 by 5  μm. The most morphologically similar lichen is Halecania rhypodiza , but this species has a dark brown thallus and larger spores measuring 12–15 by 4.5–6 μm. [1]

<i>Hydropunctaria</i> Genus of lichen

Hydropunctaria is a genus of saxicolous (rock-dwelling), crustose lichens in the family Verrucariaceae. The genus includes both aquatic and amphibious species, with members that colonise either marine or freshwater habitats. The type species, Hydropunctaria maura, was formerly classified in the large genus Verrucaria. It is a widely distributed species common to littoral zones. Including the type species, five Hydropunctaria lichens are considered marine species: H. adriatica, H. amphibia, H. aractina, H. orae, and H. oceanica.

<i>Halecania</i> Genus of fungi

Halecania is a genus of fungi in the family Leprocaulaceae. It has 22 species. The genus was circumscribed by Austrian lichenologist Michaela Mayrhofer in 1987, with Halecania alpivaga assigned as the type species. She created Halecania to contain species, formerly placed in Lecania, with the following characteristics: uniformly amyloid apical domes, paraphyses with dark brown apical caps, and halonate ascospores.

Atrophysma is a fungal genus in the family Pannariaceae. It contains the single species Atrophysma cyanomelanos, a crustose lichen found only in Alaska.

Xenonectriella nephromatis is a species of lichenicolous fungus in the family Nectriaceae. Found in Alaska, it was described as a species new to science in 2020 by Sergio Pérez-Ortega. The type specimen was discovered in the Hoonah–Angoon Census Area in Glacier Bay National Park, where it was growing on a Nephroma lichen. The specific epithet alludes to this host lichen.

Corticifraga nephromatis is a species of lichenicolous fungus in the family Gomphillaceae. Found in Alaska, it was described as a new species by Sergio Pérez-Ortega. The type was found in the Hoonah-Angoon Census Area in the east arm of Glacier Bay, where it was growing on the thallus of the foliose lichen Nephroma bellum. The specific epithet refers to the host lichen.

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.

Bacidina circumpulla is a species of crustose lichen in the family Ramalinaceae. Found in Alaska and British Columbia, it was described as a new species in 2020 by Stefan Ekman.

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.

Sclerococcum fissurinae is a species of lichenicolous fungus in the family Dactylosporaceae. Found in Alaska, it was formally described as a new species in 2020 by Sergio Pérez-Ortega. The type specimen was collected in the Hoonah-Angoon Census Area, just outside of Glacier Bay National Park. Here it was found growing on the script lichen species Fissurina insidiosa, which itself was growing on the bark of an alder tree. The specific epithet refers to its host.

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.

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.

Niesslia peltigerae is a species of lichenicolous fungus in the family Niessliaceae. It was described as a new species in 2020 by lichenologist Sergio Pérez-Ortega. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park, in muskeg and forest. The fungus was growing parasitically on the lichen Peltigera kristinssonii, which itself was growing on mountain hemlock. The specific epithet peltigerae alludes to the genus of its host. Infection by the fungus bleaches the thallus of the host lichen.

Ochrolechia cooperi is a species of crustose lichen in the family Ochrolechiaceae. Occurring only in southern Alaska, it was formally 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, northeast of Gustavus. Here the lichen was found in muskeg growing on a conifer log that still had its bark. The specific epithet honors American ecologist William Skinner Cooper, "whose studies on plant succession in Glacier Bay and subsequent political lobbying efforts were influential in the establishment of Glacier Bay as a National Monument in 1925".

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".
