The Pannariaceae are a family of lichens in the order Peltigerales. Species from this family have a widespread distribution, but are especially prevalent in southern temperate regions.
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.
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.
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.
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.
Niesslia is a genus of fungi in the family Niessliaceae. It was circumscribed by German mycologist Bernhard Auerswald in 1869, with Niesslia chaetomium assigned as the type species.
Xenonectriella is a genus of lichenicolous fungi in the family Nectriaceae. The genus was circumscribed by lichenologist Josef Karl Weese in 1919, with Xenonectriella lutescens assigned as the type species.
Coccotrema is a genus of lichen-forming fungi. It is the type genus of the family Coccotremataceae, in the order Pertusariales. The genus contains 16 species.
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.
Cordieritidaceae is a family of fungi in the order Cyttariales. Species in this family are saprobes or lichenicolous.
Sclerococcum is a genus of lichenicolous fungi in the family Dactylosporaceae.
Steineropsis is a genus of lichen-forming fungi in the family Pannariaceae. It has two species. The genus was circumscribed by Toby Spribille and Lucia Muggia in 2010, with Steineropsis alaskana assigned as the type species. The type specimen of this lichen was found in Skagway, Alaska, where it was growing on a rock in a snowbed at an altitude of 1,051 m (3,448 ft). The generic name alludes to a resemblance to the genus Steinera. A second species, Steineropsis laceratula, also found in Alaska, was added to the genus in 2020. Molecular phylogenetic analysis showed that Steineropsis has a sister taxon relationship to genus Protopannaria.
Atrophysma is a fungal genus in the family Pannariaceae. It contains the single species Atrophysma cyanomelanos, a crustose lichen found only in Alaska.
Corticifraga nephromatis is a species of lichenicolous fungus in the family Gomphillaceae. Found in Alaska, it was described as a new species by Sergio Pérez-Ortega. The type was found in the Hoonah-Angoon Census Area in the east arm of Glacier Bay, where it was growing on the thallus of the foliose lichen Nephroma bellum. The specific epithet refers to the host lichen.
Polycoccum is a genus of lichenicolous fungi in the family Polycoccaceae. It has about 60 species.
Niesslia peltigerae is a species of lichenicolous fungus in the family Niessliaceae. It was described as a new species in 2020 by lichenologist Sergio Pérez-Ortega. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park, in muskeg and forest. The fungus was growing parasitically on the lichen Peltigera kristinssonii, which itself was growing on mountain hemlock. The specific epithet peltigerae alludes to the genus of its host. Infection by the fungus bleaches the thallus of the host lichen.
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.
Minutoexcipula is a genus of lichenicolous (lichen-dwelling) fungi of uncertain familial placement in the order Chaetothyriales. It has eight species. The genus was circumscribed in 1994 by M. Violeta Atienza Tamarit and David Leslie Hawksworth, with Minutoexcipula tuckerae assigned as the type species. The genus is characterized both by its black convex sporodochia-like conidiomata, as well as the well-differentiated exciple on these structures.
