Scutula is a genus of lichenicolous fungi in the family Ramalinaceae.
Unguiculariopsis is a genus of lichenicolous fungi in the family Cordieritidaceae. It has 29 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.
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.
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.
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.
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.
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.
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.
Corticifraga is a genus of lichenicolous fungi in the family Gomphillaceae. The genus was circumscribed by David Leslie Hawksworth and Rolf Santesson in 1990, with Corticifraga peltigerae assigned as the type species.
Cordieritidaceae is a family of fungi in the order Cyttariales. Species in this family are saprobes or lichenicolous.
Lichenosticta is a genus of fungi of uncertain familial placement in the order Lecanorales. It has five species. All species are lichenicolous, meaning they are parasitic on lichens.
Xenonectriella subimperspicua is a species of lichenicolous fungus in the family Nectriaceae. It has been recorded from South America, Europe, and New Zealand.
Polycoccum is a genus of lichenicolous fungi in the family Polycoccaceae. It has about 60 species.
Abrothallus halei is a species of lichenicolous fungus in the family Abrothallaceae. It was formally described as a new species in 2010 by lichenologists Sergio Pérez-Ortega, Ave Suija, David Leslie Hawksworth, and Rolf Santesson. The type specimen was collected by Cliff Wetmore east of Hare Lake at an elevation of 550 m (1,800 ft); there it was found on the foliose lichen Lobaria quercizans, which itself was growing on the bark of Acer saccharum. The fungus has also been collected in West Virginia, Maine, as well as in Norway. The species epithet honours American lichenologist Mason Hale.
