Phoma is a genus of common coelomycetous soil fungi. It contains many plant pathogenic species.
Lichenochora is a genus of fungi in the family Phyllachoraceae. It has 44 species. All species in the genus are lichenicolous, meaning they grow parasitically on lichens. The genus was circumscribed by Josef Hafellner in 1989, with Lichenochora thallina assigned as the type species.
Stigmidium is a genus of lichenicolous (lichen-eating) fungi in the family Mycosphaerellaceae. The genus was circumscribed by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1860, with Stigmidium schaereri assigned as the type species.
Lepraria is a genus of leprose crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains. Members of the genus are commonly called dust lichens. The main vegetative body (thallus) is made of patches of soredia. There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products are important characters to distinguish between similar species in Lepraria.
Lichenostigma is a genus of fungi. It includes several species which are lichenicolous.
Candelariella aurella, the hidden goldspeck lichen or eggyolk lichen, is a yellow crustose lichen in the family Candelariaceae. It is commonly found on calcareous rock or wood or bark exposed to sunlight and which may have calcareous dust in areas with lime soils. The thallus is areolate with scattered small (0.1–0.3 mm), rounded to elongated yellow areolas. It has a global distribution and occurs on limestone and calcareous sandstone in the Sonoran Desert in Arizona, California, and Baja California. It occurs in Joshua Tree National Monument.
Lepraria pacifica, the Pacific dust lichen, is a whitish-blue-green leprose crustose lichen that grows on its substrate like patches of granular, caked-up, mealy dust grains. Like other members of the Lepraria genus, it only reproduces asexually.
Parvoplaca is a genus of lichen-forming fungi in the family Teloschistaceae. The genus was circumscribed in 2013 by Ulrik Søchting, Patrik Frödén, and Ulf Arup.
Polycoccum is a genus of lichenicolous fungi in the family Polycoccaceae. It has about 60 species.
Lepraria incana is a species of dust lichen in the family Stereocaulaceae. First described scientifically by Johann Jacob Dillenius in 1741, and then formally by Carl Linnaeus in 1753, it is the type species of the genus Lepraria. The thallus of this species is green to greyish-green, and powdery – as if made of tiny granules. These granules are soredia, which are asexual reproductive structures. Like most members of genus Lepraria, the lichen has few distinguishing features, lacking both a medulla and sexual reproductive structures (apothecia). Chemically, the lichen is characterised by the presence of the secondary chemicals known as divaricatic acid and zeorin.
Lendemeriella is a genus of crustose lichens in the subfamily Caloplacoideae of the family Teloschistaceae. It has ten species. The genus was circumscribed in 2020 by Sergey Kondratyuk, with Lendemeriella reptans assigned as the type species. The genus name honours the American lichenologist James Lendemer, who co-authored the type species in 2012.
Psora taurensis is a species of terricolous (ground-dwelling), squamulose lichen in the family Lecanoraceae. It is found in the Taurus Mountains of Turkey.
Phoma candelariellae is a species of lichenicolous (lichen-eating) fungus in the family Didymellaceae. It is found in the Central Anatolia Region of Turkey and in Ukraine, where it grows parasitically on the apothecia of the saxicolous (rock-dwelling) lichen Candelariella aurella.
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.
Catapyrenium boccanum is a species of squamulose (scaley), rock-dwelling lichen in the family Verrucariaceae. It grows on mortar or on calcareous rock. Its squamules are up to 4 mm wide, pale to dark brown with black margins and a black underside. Ascospores measure 11–15 by 5–8 μm. Because of its combination of squamulose thallus, simple ascospores, and lack of algae in the hymenium, this species is a "catapyrenioid" lichen, of which more than 80 exist in the Verrucariaceae.
Gemmaspora is a single-species fungal genus of uncertain familial placement in the order Verrucariales. It contains Gemmaspora lecanorae, a lichenicolous (lichen-dwelling) fungus that parasitises the lichen genus Aspicilia. The genus was proposed in 2007 by David Hawksworth and Gökhan Halici to contain the fungus formerly known as Adelococcus lecanorae. This species, originally described by Roger-Guy Werner in 1963, occurs in Syria and Turkey.
Shackletonia is a genus of lichen-forming fungi in the family Teloschistaceae. The species in the Shackletonia genus are lichenicolous and muscicolous, and known from Antarctica and southern Patagonia.
Parvoplaca nigroblastidiata is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. Found in Europe and Alaska, it was formally described as a new species in 2015 by Ulf Arup, Jan Vondrák, and Mehmet Halıcı. The type specimen was collected in the Nyhem Parish, Jämtland (Sweden), where it was growing on the bark of Populus tremula. In Turkey, it has been recorded at high altitudes on the bark of Juniperus excelsa and Abies cilicica, while in a single record from Alaska it is growing on Populus. In 2018 it was reported from the sacred groves of Epirus in Greece, and in 2020 from Norway.
Catenarina desolata is a species of lichen in the family Teloschistaceae. It was formally described as a new species in 2014 by lichenologists Ulrik Søchting, Majbrit Søgaard, and Arve Elvebakk. It is predominantly found in the southernmost parts of Chile, with some instances in Antarctica and the Kerguelen Islands. Characterised by its dark reddish-brown to almost purple apothecia, this species of lichen was originally thought to be lichenicolous, meaning it grows on other lichens, particularly Aspicilia species. The later discovery non-lichen-dwelling examples from James Ross Island in the Antarctic Peninsula suggests that it is not exclusively lichenicolous. Its distinctive secondary compound, 7-chlorocatenarin, sets it apart from other lichens in the region.
Calogaya orientalis is a species of corticolous (bark-dwelling) and muscicolous lichen (moss-dwelling), crustose lichen in the family Teloschistaceae. It is found in arid steppe and desert habitats in Northwestern China, Iran, and Turkey. The thallus of this lichen is reduced, similar to species in the genus Athallia.
