Scutula is a genus of lichenicolous fungi in the family Ramalinaceae.
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.
Skyttella is a genus of lichenicolous fungi in the family Cordieritidaceae. It contains two species. The genus was circumscribed in 1988 by David Leslie Hawksworth and Rolf Santesson, with Skyttella mulleri assigned as the type species. This species, which parasitizes the lobes of foliose lichens in the genus Peltigera, was previously classified in the genus Phacopsis. Skyttella stictae, an Ecuadorian species that grows on Sticta, was added to the genus in 2017.
Peltigera aphthosa is a species of lichen known by the common names green dog lichen, leafy lichen, felt lichen, and common freckle pelt. It has a circumpolar distribution, occurring throughout the Arctic, boreal, and temperate regions of the Northern Hemisphere.
Tricharia vainioi is a species of foliicolous lichen in the family Gomphillaceae. It is widely distributed, having been recorded in Africa, Asia, Australia, Central and South America.
Rolf Santesson (1916–2013) was a Swedish lichenologist and university lecturer. He was awarded the Acharius Medal in 1992 for his lifetime contributions to lichenology.
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.
Stereocaulon paschale is a species of lichen belonging to the family Stereocaulaceae.
Cladonia uncialis is a species of fruticose, cup lichen in the family Cladoniaceae. It was first described as a new species by Swedish taxonomist Carl Linnaeus in 1753. It was transferred to the genus Cladonia by Friedrich Heinrich Wiggers in 1780. In North America, the lichen is colloquially known as the thorn Cladonia or the thorn cup lichen.
Stereocaulon alpinum is a species of fungus belonging to the family Stereocaulaceae. It is similar to Stereocaulon paschale but differs from it in containing cyanobacteria of the genus Nostoc while S. paschale contains cyanobacteria of the genus Stigonema, which have a darker colour than Nostoc.
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.
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 ventosicola is a species of lichenicolous fungus in the family Verrucariaceae. It shows preference to growing on species of the genus Rhizocarpon but can also associate with other genera.
Lichenopeltella uncialicola is a species of fungus belonging to the class Dothideomycetes. The species was discovered in Iceland in 2010 where it was found growing on Cladonia uncialis. Since then, it has been found on a different host species, Cladonia rangiferina, in North-Korea, Italy Austria, and Greenland.
Lichenoconium pyxidatae is a species of lichenicolous fungus belonging to the class Dothideomycetes. It has a Holarctic distribution being found in Alaska and various parts of Russia, including Siberia, Franz Josef Land, Novaya Zemlya and Wrangel Island.
Xenonectriella subimperspicua is a species of lichenicolous fungus in the family Nectriaceae. It has been recorded from South America, Europe, and New Zealand.
Stereocaulon rivulorum is a species of snow lichen belonging to the family Stereocaulaceae.
Cercidospora stereocaulorum is a species of lichenicolous fungus in the genus Cercidospora but it has not been assigned to a family. It is known to parasitise lichens of the genus Stereocaulon.
Abrothallus secedens is a species of lichenicolous fungus in the family Abrothallaceae. Found in Africa, South America, and the United States, it was formally described as a new species in 1994 by Swedish lichenologists Mats Wedin and Rolf Santesson. The type specimen was collected by the first author on the Martial Glacier in Ushuaia at an altitude of 550 m (1,800 ft), where it was found on the thallus of the foliose lichen Pseudocyphellaria dubia, which itself was growing on the base of a Nothofagus antarctica tree. It has also been collected in Chile, Kenya, and Alaska. The species epithet of the fungus, secedens refers to the two-celled ascospores that eventually separate into single-celled part spores. Known hosts for Abrothallus secedens include Crocodia aurata, Pseudocyphellaria dubia, P. mallota, P. obvoluta, and other Pseudocyphellaria lichens not identified to species.
