Biatorellaceae is a family of lichen-forming fungi in the subclass Lecanoromycetidae. The family is monotypic, and contains the single genus Biatorella, which contains eight 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.
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.
Telogalla is a genus of lichenicolous fungi in the family Verrucariaceae. It has two species. The genus was circumscribed by Nikolaus Hoffmann and Josef Hafellner.
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.
Xanthopyreniaceae is a family of lichen-forming fungi in the order Collemopsidiales. The family was circumscribed by lichenologist Alexander Zahlbruckner in 1926.
Abrothallus is a genus of lichenicolous fungi. It is the only genus in the monotypic family Abrothallaceae, which itself is the sole taxon in the order Abrothallales.
Gyrophthorus is a genus of lichenicolous (lichen-dwelling) fungi in the phylum Ascomycota. The relationship of this taxon to other taxa within the phylum is unknown, and it has not yet been placed with certainty into any class, order, or family. The genus was circumscribed in 1990 by Josef Hafellner and Leopoldo Sancho, with Gyrophthorus perforans assigned as the type species.
Zwackhiomyces is a genus of lichenicolous fungi in the family Xanthopyreniaceae. The genus was circumscribed by Martin Grube and Josef Hafellner in 1990, with Zwackhiomyces coepulonus assigned as the type species.
Rhymbocarpus is a genus of lichenicolous (lichen-dwelling) fungi in the family Cordieritidaceae. It has 10 species. The genus was circumscribed by German mycologist Friedrich Wilhelm Zopf in 1896, with Rhymbocarpus punctiformis assigned as the type species.
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.
Josef Hafellner is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus Karschia. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae has been described as "probably the single most influential publication in lichen systematics in the latter half of the 20th century".
Leprocaulaceae is a family of mostly lichen-forming fungi. It is the single family in the monotypic order Leprocaulales. Leprocaulaceae contains three genera and about 33 species.
Xenonectriella subimperspicua is a species of lichenicolous fungus in the family Nectriaceae. It has been recorded from South America, Europe, and New Zealand.
Halospora is a genus of lichenicolous (lichen-dwelling) fungi in the family Verrucariaceae. Species in the genus parasitise calcicolous crustose lichens, i.e., those that prefer lime-rich substrates.
Piccolia is a small genus of crustose lichens in the class Lecanoromycetes. First circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1864, it contains ten species. Due to a lack of molecular data, it has not been assigned to an order or family.
Abrothallus welwitschii is a species of lichenicolous fungus in the family Abrothallaceae. It grows on species of the foliose lichen genus Sticta. The type specimen was originally collected in Portugal in 1840 by Austrian botanist Friedrich Welwitsch, and it is after him for whom the species is named. Camille Montagne described the species in 1851, but he did not published the name validly; it was published validly by Charles Tulasne a year later.
Zwackhiomyces echinulatus is a species of lichenicolous (lichen-dwelling) fungus in the family Xanthopyreniaceae. Thus fungus exclusively colonises the lichen species Physconia distorta. This fungus is notable for specific structural features that distinguish it from other members of its genus, and for its niche habitat found only in particular regions of Sicily, Italy.
Stigmidium cerinae is a species of lichenicolous (lichen-dwelling) fungus in the family Mycosphaerellaceae. It was formally described as a new species in 1994 by mycologists Claude Roux and Dagmar Triebel. The type specimen was collected in Austria from the apothecia of the muscicolous (moss-dwelling) species Caloplaca stillicidiorum. It infects lichens in the genus Caloplaca, and more generally, members of the family Teloschistaceae. Infection by the fungus results in bleaching of the host hymenium.
