Petractis is a genus of lichenized fungi of uncertain familial and ordinal placement in the Lecanoromycetes. [1] The genus was circumscription by mycologist Elias Magnus Fries in 1846. [2]
Capnodiales is a diverse order of Dothideomycetes, initially based on the family Capnodiaceae, also known as sooty mold fungi. Sooty molds grow as epiphytes, forming masses of black cells on plant leaves and are often associated with the honeydew secreted by insects feeding on plant sap. This diverse order has been expanded by the addition of several families formerly thought unrelated and now also includes saprobes, endophytes, plant pathogens, lichens and rock-inhabiting fungi. The new additions include the genus Mycosphaerella containing the causal agents of several economically important crop and tree diseases. A small number of these fungi are also able to parasitise humans and animals, including species able to colonise human hair shafts.
Pleosporaceae is a family of sac fungi. They are pathogenic to humans or saprobic on woody and dead herbaceous stems or leaves.
Diaporthales is an order of sac fungi.
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.
The Sphaerophoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution, especially in southern temperate regions. Sphaerophoraceae was circumscribed by mycologist Elias Magnus Fries in 1831.
The Stictidaceae are a family of fungi in the order Ostropales. The family was first described by Swedish mycologist Elias Magnus Fries in 1849.
Thysanothecium is a genus of three species of lichenized fungi in the family Cladoniaceae. The genus was circumscribed by Camille Montagne and Miles Joseph Berkeley in 1846. The original specimens of the type species, T. hookeri, were collected from the area of Swan River (Australia) by James Drummond, who sent them for to William Jackson Hooker for further analysis.
Coscinocladium is a genus of two species of lichenized fungi in the family Physciaceae.
Combea is a genus of lichens in the family Opegraphaceae. It has two species. The genus was circumscribed by Italian botanist Giuseppe De Notaris in 1846.
Schizopelte is a genus of lichen-forming fungi in the family Opegraphaceae. The genus was circumscribed by Theodor Magnus Fries in 1875. It was resurrected for use in 2011 by Damien Ertz and Anders Tehler, who published a phylogenetic study of the order Arthoniales. In addition to the type species, S. californica, they included a former Hubbsia species, a former Llimonaea species, and a species new to science in the resurrected Schizopelte.
Meliola is a large genus of fungi in the family Meliolaceae. It was circumscribed by Swedish mycologist Elias Magnus Fries in 1825.
Parmularia is a genus of fungi in the family Parmulariaceae. The genus was circumscribed by Joseph-Henri Léveillé in 1846.
Leciophysma is a genus of cyanolichens in the family Pannariaceae. It has four species. The genus was circumscribed by Theodor Magnus Fries in 1865, with Leciophysma finmarkicum assigned as the type species.
The Arctomiaceae are a family of lichenized fungi in the Ascomycota, class Baeomycetales. The family was named by Theodor Magnus Fries in 1861, with Arctomia as the type genus. Species in this family are found in arctic and subarctic habitats, usually associated with bryophytes.
Arctomia is a genus of lichen-forming fungi in the family Arctomiaceae. The genus was originally circumscribed by Theodor Magnus Fries in 1861. Arctomia has a circumpolar distribution.
Bulgaria is a genus of fungi in the family Phacidiaceae. The genus was circumscribed in 1822 by Elias Magnus Fries, with Bulgaria inquinans assigned as the type species.
Opegraphaceae is a family of lichen-forming and lichenicolous fungi in the order Arthoniales. It was originally proposed by German lichenologist Ernst Stizenberger in 1862. It fell into disuse, but was resurrected in a molecular phylogenetic study of the order Arthoniales published in 2010. It now includes taxa that were previously referred to the family Roccellaceae, its sister group.
Arthrorhaphis is a genus of lichen-forming fungi in the monotypic family Arthrorhaphidaceae. It has 13 species. The genus was circumscribed by Theodor Magnus Fries in 1860. The family was proposed by lichenologists Josef Poelt and Josef Hafellner in 1976. Species in this family have a widespread distribution in temperate and montane habitats. They grow symbiotically with green algae, or parasitically on other lichens. The family Arthrorhaphidaceae has an uncertain taxonomic placement in the class Lecanoromycetes; that is, it is incertae sedis with respect to ordinal placement.
Hyaloraphidium is a genus of chytrid-like fungi. It is the only member of the family Hyaloraphidiaceae, order Hyaloraphidiales and class Hyaloraphidiomycetes in the division Monoblepharomycota.
Ionaspis is a genus of lichen-forming fungi in the family Hymeneliaceae. It contains six species of saxicolous (rock-dwelling), crustose lichens. The genus was originally circumscribed in 1871 by Theodor Magnus Fries. He segregated the genus from Aspicilia based on the presence of Trentepohlia rather than Trebouxia as the photobiont partner.
