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. Species in the genus are found in northern temperate regions, especially in Europe.
Porina is a genus of lichens in the family Trichotheliaceae. A 2020 estimate places about 145 species in the widespread genus.
Enterographa is a genus of lichens in the family Roccellaceae.
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.
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.
Sagiolechia is a genus of lichen-forming fungi in the family Sagiolechiaceae. The genus was circumscribed by lichenologist Abramo Bartolommeo Massalongo in 1854, who assigned Sagiolechia protuberans as the type species. The family Sagiolechiaceae was proposed in 2010 to contain Sagiolechia as the type genus, and genus Rhexophiale; molecular phylogenetic analysis showed that these two genera formed a distinct clade in the Ostropales.
Synarthonia is a genus of lichen-forming fungi in the order Arthoniales. The genus has not been placed into a family. Synarthonia was circumscribed by Swiss lichenologist Johannes Müller Argoviensis in 1891.
Nesolechia is a genus of parasitic fungi in the family Parmeliaceae. All three species in the genus grow on lichens. Nesolechia probably evolved from a lichen ancestor, as it is closely related to many lichenized species of fungi.
The Trypetheliales are an order of fungi in the class Dothideomycetes. Most of the species in the order form lichens, although some are lichenicolous fungi. Trypetheliales contains two families, Polycoccaceae and Trypetheliaceae. The order was circumscribed in 2008 by lichenologists Robert Lücking, André Aptroot, and Harrie Sipman.
André Aptroot is a Dutch mycologist and lichenologist.
Emmanuël Sérusiaux is a Belgian lichenologist. His career, spanning more than four decades, has combined both lichenology research and political aspects of nature conservation. He spent several periods working as a researcher at the National Fund for Scientific Research and the University of Liège, the latter in which he accepted a faculty position as professor and head of the Plant Taxonomy and Conservation Biology unit. Sérusiaux also served for three non-consecutive appointments as Deputy Chief of Staff in the Government of Wallonia. He retired from both his academic and political positions in 2019.
Catillaria is a genus of crustose lichens in the family Catillariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852. It is the type genus of Catillariaceae, which was circumscribed by Austrian lichenologist Josef Hafellner in 1984.
Sclerococcum is a genus of lichenicolous fungi in the family Dactylosporaceae.
Solenopsora is a genus of lichen-forming fungi in the family Catillariaceae. It has 15 species, with a mostly Northern Hemisphere distribution.
Loxospora is a genus of lichen-forming fungi in the family Sarrameanaceae. It has 13 species. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852, with Loxospora elatina assigned as the type species. This crustose lichen was originally named Lecanora elatina by Erik Acharius in 1810.
Klaus Kalb is a German lichenologist and an authority on tropical lichens.
Synarthonia leproidica is a species of saxicolous (rock-dwelling) and crustose lichen in the order Arthoniales. Found in Luxembourg, it was formally described as a new species in 2020 by lichenologists Damien Ertz, André Aptroot, and Paul Diederich. The type specimen was collected in the Vallée du Lellgerbaach (Lellingen) at an elevation of 323 m (1,060 ft). Here the lichen was found on a siliceous wall at the edge of a forest path in an oak-hornbeam forest. It has a pale greyish crust-like thallus with dark brown/violet tinges. It has a leproid growth form, meaning that it looks like it is made of granules; the specific epithet refers to this characteristic. The thallus forms patches that are about 0.5–5 mm in diameter, although neighbouring patches can coalesce to form larger patches up to 10 cm (4 in) in diameter. Synarthonia leproidica contains psoromic acid, a secondary chemical that can be detected with thin-layer chromatography.
Phacopsis thallicola is a species of lichenicolous (lichen-dwelling) fungus in the family Parmeliaceae. It was first formally described as a new species in 1852 by Italian botanist Abramo Bartolommeo Massalongo, as Lecidea thallicola. The type specimen, collected from the province of Treviso in Italy, was growing on the foliose lichen Parmelia caperata. Dagmar Triebel and Gerhard Walter Rambold transferred the taxon to the genus Phacopsis in 1988. The known generic hosts of Phacopsis thallicola are all in the Parmeliaceae: Parmotrema, Cetrelia, Flavopunctelia, and Hypotrachyna.
Zwackhiomyces calcariae is a species of lichenicolous fungus in the family Xanthopyreniaceae. It was first formally described in 1896 by French lichenologist Camille Flagey, as Arthopyrenia calcariae. Josef Hafellner and Nikolaus Hoffmann transferred it to the genus Zwackhiomyces in 2000. The fungus is parasitic on lichens in genus Aspicilia.
Reichlingia is a genus of lichen-forming fungi in the family Arthoniaceae. It has seven species. The genus was originally circumscribed by Paul Diederich and Christoph Scheidegger in 1996, with Reichlingia leopoldii as the type, and at that time, only species. The fungus was at first thought to be a lichenicolous (lichen-dwelling) fungus, but is now considered a lichenised hyphomycete.
