Geltingia is a fungal genus in the family Helicogoniaceae. It is monotypic, containing the single lichenicolous species Geltingia associata. The genus was circumscribed in 1990 by mycologists Vagn Alstrup and David Leslie Hawksworth. The genus name honours Danish scientist Paul Gelting.
Endococcus is a genus of lichenicolous (lichen-dwelling) in the family Lichenotheliaceae. It has 44 species. The genus was circumscribed by the Finnish botanist William Nylander in 1855. Although at least one source places the genus in the Verrucariaceae, a 2016 study of the type species, Endococcus rugulosus, determined that it should instead be placed in the family Lichenotheliaceae of the order Dothideales; this classification echoes a placement proposed in 1979 by David Hawksworth.
Carbonea is a genus of fungi in the family Lecanoraceae. Most of the species grow on lichens. The genus is widespread, and contains 20 species. Carbonea was originally circumscribed as a subgenus of Lecidea in 1967 before it was promoted to generic status in 1983.
Nesolechia is a genus of parasitic fungi in the family Parmeliaceae. All three species in the genus grow on lichens. Nesolechia probably evolved from a lichen ancestor, as it is closely related to many lichenized species of fungi.
Phacopsis is a genus of lichenicolous (lichen-dwelling) fungi. They are parasites of members of the large lichen family Parmeliaceae, of which they are also a member. Originally proposed by Edmond Tulasne in 1852 to contain 3 species, Phacopsis now contains 10 species, although historically, 33 taxa have been described in the genus. Many of the species are poorly known, some of them having been documented only from the type specimen.
The wildlife of Antarctica are extremophiles, having to adapt to the dryness, low temperatures, and high exposure common in Antarctica. The extreme weather of the interior contrasts to the relatively mild conditions on the Antarctic Peninsula and the subantarctic islands, which have warmer temperatures and more liquid water. Much of the ocean around the mainland is covered by sea ice. The oceans themselves are a more stable environment for life, both in the water column and on the seabed.
A lichenicolous fungus is a parasitic fungus that only lives on lichen as the host. A lichenicolous fungus is not the same as the fungus that is the component of the lichen, which is known as a lichenized fungus. They are most commonly specific to a given fungus as the host, but they also include a wide range of pathogens, saprotrophs, and commensals. It is estimated there are 3000 species of lichenicolous fungi. More than 1800 species are already described among the Ascomycota and Basidiomycota. More than 95% of lichenicolous fungi described as of 2003 are ascomycetes, in 7 classes and 19 orders. Although basidiomycetes have less than 5% of lichenicolous lichen species, they represent 4 classes and 8 orders. Many lichenicolous species have yet to be assigned a phylogenetic position as of 2003.
Candelariella vitellina is a common and widespread green-yellow to orange-yellow crustose areolate lichen that grows on rock, wood, and bark, all over the world. It grows on non-calcareous rock, wood, and bark. It often has tiny lobate areoles in the shape of lion claws. The areoles may be flat or convex. Its sexual reproduction structures (apothecia) are a 0.35–1.0 mm-wide disc, darker yellow than the thallus, rimmed with thallus-like tissue lecanorine, flat but becoming convex with age. Lichen spot tests are K+ reddish, KC−, and C−. It produces calycin, pulvinic acid, pulvinic dilactone and vulpinic acid as secondary metabolites.
Lecanora cenisia is a species of crustose lichen in the family Lecanoraceae. It is a known host of the lichenicolous fungus species Carbonea supersparsa.
Lecanora impudens is a species of crustose lichen in the family Lecanoraceae. It was described as new to science by Gunnar Degelius in 1944.
Lecanora polytropa, commonly known as the granite-speck rim lichen, is a species of saxicolous lichen in the family Parmeliaceae. A small, inconspicuous species that grows in the cracks of rock surfaces, it has a cosmopolitan distribution and has been recorded on all continents, including Antarctica.
Carbonea supersparsa is a species of lichenicolous fungus belonging to the family Lecanoraceae. It is widespread in the Northern Hemisphere. In Iceland it has been reported growing on Lecanora cenisia near Egilsstaðir and Lecanora polytropa near Seyðisfjörður.
Carbonea vitellaria is a species of lichenicolous fungus belonging to the family Lecanoraceae. It has a worldwide distribution. In Iceland it has been reported growing on Candelariella vitellina near Egilsstaðir and on King George Island, Antarctica.
Muellerella lichenicola is a species of lichenicolous fungus in the family Verrucariaceae. It was first formally described as a new species in 1826 by Søren Christian Sommerfelt, as Sphaeria lichenicola. David Leslie Hawksworth transferred it to the genus Muellerella in 1979.
Muellerella pygmaea is a species of lichenicolous fungus in the family Verrucariaceae. It has a cosmopolitan distribution in Arctic-alpine areas and grows on the thallus and apothecia of a number of hosts.
Pyrenidium is a genus of lichenicolous (lichen-dwelling) fungi. It is the only genus in the family Pyrenidiaceae. It has 13 species.
Shackletonia is a genus of lichen-forming fungi in the family Teloschistaceae, they are lichenicolous, and muscicolous species and known from Antarctica and southern Patagonia.
Carbonea austroshetlandica is a species of lichenicolous fungus belonging to the family Lecanoraceae. It was discovered in the South Shetland Islands where it grows on Carbonea assentiens but has since been reported from King George Island where it uses Rhizocarpon geographicum as a host.
Carbonea aggregantula is a species of lichen belonging to the family Lecanoraceae.
Porpidia submelinodes is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecideaceae. Found in the South Shetland Islands of Antarctica, it was formally described as a new species in 2011 by lichenologists Piotr Osyczka and Maria Olech. The type specimen was collected from Penguin Island, where it was found growing on a volcanic boulder. The lichen has a rusty orange thallus comprising distinct rounded areoles surrounded by deep cracks, and an inconspicuous black prothallus. It has soralia that are black with a whitish rim. All examined specimens were sterile, producing neither apothecia nor pycnidia. All chemical spot tests are negative, and the species does not contain any lichen products detectable with thin-layer chromatography. The species epithet refers to its similarity with Porpidia melinodes.
