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.
Opegrapha is a genus of lichenized fungi in the family Opegraphaceae. Species include:
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.
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.
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.
Didymocyrtis is a genus of lichenicolous fungi in the family Phaeosphaeriaceae. The genus was circumscribed by Finnish lichenologist Edvard August Vainio in 1921, with Didymocyrtis consimilis assigned as the type species.
Pronectria is a genus of fungi in the family Bionectriaceae. It consists of 44 species, all of which are lichenicolous. The genus was circumscribed by American plant ecologist Frederic Clements in 1931.
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.
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.
Llimoniella is a genus of fungi in the family Cordieritidaceae. The genus was circumscribed by lichenologists Josef Hafellner and Père Navarro-Rosinés in 1993.
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.
Skyttea is a genus of lichenicolous (lichen-dwelling) fungi in the family Cordieritidaceae. The genus was circumscribed in 1981 by lichenologists Martha Allen Sherwood, David L. Hawksworth, and Brian J. Coppins, with Skyttea nitschkei assigned as the type species.
Lichenostigma is a genus of fungi. It includes several species which are lichenicolous.
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".
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.
Taeniolella serusiauxii is a species of lichenicolous fungus in the family Mytilinidiaceae. It was described as a new species in 1992 by Paul Diederich. The type was collected in France, where it was found growing on Dendrographa decolorans. The specific epithet serusiauxii honours the Belgian lichenologist Emmanuël Sérusiaux.
Sclerococcum is a genus of lichenicolous fungi in the family Dactylosporaceae.
Polycoccum is a genus of lichenicolous fungi in the family Polycoccaceae. It has about 60 species.
