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.
Sphaerellothecium is a genus of fungi in the family Phyllachoraceae. All of the species in the genus are lichenicolous, meaning they grow parasitically on lichens.
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.
Cetraria aculeata or the spiny Iceland lichen is a dark brown to black fruticose, soil Iceland lichen from the family Parmeliaceae. The species was first described by German naturalist Johann Christian Daniel Edler von Schreber in 1771 under the name of Lichen aculeatus. Later on, Erik Acharius, the "father of lichenology" gave it a name of Cornicularia aculeata, which lately has been changed to Coelocaulon aculeatum. Finally, the taxonomic revision of Ingvar Kärnefelt and colleagues assigned the species to the genus Cetraria.
Ovicuculispora parmeliae is a widely distributed species of lichenicolous fungus in the family Bionectriaceae. It is parasitic on many foliose lichen species, particularly those in the family Parmeliaceae.
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.
Buelliella lecanorae is a species of lichenicolous (lichen-eating) fungus in the class Dothideomycetes. It is found in a few locations in Estonia and in Crimea, where it grows parasitically on members of the Lecanora subfusca species group.
Graphium samogiticum is a little-known species of lichenicolous (lichen-eating) fungus in the family Microascaceae. It is found in Lithuania, where it parasitises two lichen species that inhabit abandoned gravel pits.
Stereocaulon vesuvianum is a species of snow lichen belonging to the family Stereocaulaceae.
Stereocaulon glareosum is a species of snow lichen belonging to the family Stereocaulaceae.
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.
Sphaerellothecium araneosum is a species of lichenicolous fungus in the family Phyllachoraceae.
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.
Polycoccum laursenii is a species of lichenicolous fungus in the family Polycoccaceae. It was first described as a new species in 2004 by Russian mycologist Mikhail Petrovich Zhurbenko. It is found in Alaska and in Russia.
Bryostigma epiphyscium is a species of lichenicolous fungus in the order Arthoniales. Formerly classified in the genera Arthonia and Conida, it was transferred to the genus Bryostigma in 2020.
Arthonia stereocaulina is a species of lichenicolous fungus in the family Arthoniaceae.
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.
Ochrolechia frigida is a species of lichen belonging to the family Ochrolechiaceae. It was first formally described by Olof Peter Swartz in 1781, as Lichen frigidus. Bernt Arne Lynge transferred it to Ochrolechia in 1928.
Scutula stereocaulorum is a species of lichenicolous fungus in the family Ramalinaceae.
