Norrlinia is a genus of two species of fungi in the family Verrucariaceae. The genus was circumscribed by Ferdinand Theissen and Hans Sydow in 1918. The genus name honours the Finnish botanist Johan Petter Norrlin. Both species are lichenicolous, meaning they parasitise lichens. The host of both fungi is the foliose genus Peltigera.
Cercidospora is a genus of fungi in the class Dothideomycetes. The relationship of this taxon to other taxa within the class is unknown. The genus was first described by Gustav Wilhelm Körber in 1865; it is synonymous with the name Prolisea described by Frederick Edward Clements in 1931.
Catolechia is a genus of lichen-forming fungi in the family Rhizocarpaceae. It is a monotypic genus, containing the single species Catolechia wahlenbergii. The genus was circumscribed by German botanist Julius von Flotow in 1850. He did not assign a type species for the genus; Catolechia pulchellaA.Massal. (1852) was designated as the type by Gustav Wilhelm Körber in 1855. This species is synonymous with Catolechia wahlenbergii.
A lichenicolous fungus is a member of a specialised group of fungi that live exclusively on lichens as their host organisms. These fungi, comprising over 2,000 known species across 280 genera, exhibit a wide range of ecological strategies, including parasitism, commensalism, and mutualism. They can be found in diverse environments worldwide, from tropical to polar regions, and play important roles in lichen ecology and biodiversity. Lichenicolous fungi are classified into several taxonomic groups, with the majority belonging to the Ascomycota and a smaller portion to the Basidiomycota. Their interactions with host lichens range from mild parasitism to severe pathogenicity, sometimes causing significant damage to lichen communities.
Lecanora polytropa, the granite-speck rim lichen, is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecanoraceae. 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.
Stereocaulon paschale is a species of lichen belonging to the family Stereocaulaceae.
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.
Cercidospora epipolytropa is a species of lichenicolous fungus in the genus Cercidospora but it has not been assigned to a family. It is known to parasitise the crustose lichen Lecanora polytropa. The fungus was first formally described by mycologist William Mudd in 1861. Ferdinand Christian Gustav Arnold transferred it to Cercidospora in 1874.
Cercidospora thamnoliicola is a species of lichenicolous fungus in the genus Cercidospora but it has not been assigned to a family. It is known to parasitise the lichen Thamnolia vermicularis in Iceland but it is rare there. The species was first formally described by mycologist Per G. Ihlen in 1995, from specimens growing on Thamnolia vermicularis in Norway.
Stereocaulon symphycheilum is a species of snow lichen belonging to the family Stereocaulaceae.
Stereocaulon subcoralloides is a species of snow lichen belonging to the family Stereocaulaceae.
Stereocaulon botryosum is a species of snow lichen belonging to the family Stereocaulaceae.
Stereocaulon intermedium is a species of snow lichen belonging to the family Stereocaulaceae.
Stereocaulon depressum is a species of snow lichen belonging to the family Stereocaulaceae.
Stereocaulon rivulorum is a species of snow lichen belonging to the family Stereocaulaceae.
Stereocaulon groenlandicum 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.
Cladonia pocillum is a species of lichen in the family Cladoniaceae. Swedish botanist Erik Acharius first formally described the species in 1803 as Baeomyces pocillum, but Olivier Jules Richard transferred it to the genus Cladonia in 1877.
Solorina crocea, commonly known as the orange chocolate chip lichen, is a species of terricolous (ground-dwelling) and foliose (leafy) lichen in the family Peltigeraceae. The lichen, which was first formally described by Carl Linnaeus in 1753, has an arctic–alpine and circumpolar distribution and occurs in Asia, Europe, North America, and New Zealand. It generally grows on the bare ground in sandy soils, often in moist soil near snow patches or seepage areas. Although several forms and varieties of the lichen have been proposed in its history, these are not considered to have any independent taxonomic significance.
Cercidospora macrospora is a species of lichenicolous fungus in the genus Cercidospora but it has not been assigned to a family. It is known from the northern hemisphere.
