The Lichinaceae are a family of ascomycete fungi. Most species are lichenized with cyanobacteria, and have a distribution largely in temperate regions. [2]
The family was circumscribed in 1854 by Finnish lichenologist William Nylander. His description of the family mentioned the obscure brown thallus resembling algae, with an overall morphology described as either filamentous or tufted (fruticose). The fruiting structures, the apothecia, are described as either endocarpous or biatorine. He included two tribes in the Lichinaceae: Ephebeae, which contained the genera Ephebe and Gonionema, and Lichineae, which contained Lichina , the type genus. [3]
In 1986, Aino Henssen and Burkhard Büdel proposed the order Lichinales to contain the Lichinaceae. [4] In the 1980s and 1990s, several taxonomic and nomenclatural studies were the basis for the revision of many of the species in the family. [5] [6]
Heppiaceae was a family proposed by Alexander Zahlbruckner in 1906 to contain the genus Heppia . It was considered to differ from the Peltulaceae in the polysporous asci, the rostrate type of ascus (i.e., having a beaklike process), the type of photobiont, and the thallus anatomy. Heppiaceae was typically included in the order Lecanorales, while the Peltulaceae was included in the Lichinales. [7] Molecular phylogenetic methods showed that the genus Heppia forms a clade nested within the Lichinaceae, and so Heppiaceae was synonymized with Lichinaceae in 2003. [1]
First informally proposed by Antonín Vězda in 1974, then formally published in 1984 by Josef Hafellner, [8] the family Harpidiaceae contains the genera Harpidium and Euopsis. Although some authoritative sources have folded the Harpidiaceae into the Lichinaceae, some other authorities have preferred to treat the Harpidiaceae as a distinct, independent family. For example, in the Outline of the Ascomycota, the genera were included in the Lichinaceae. [7] [9] In a corrected and amended version of the "2016 classification of lichenized fungi in the Ascomycota and Basidiomycota", the Harpidiaceae was added as Pezizomycotina incertae sedis , [10] a placement followed by recent (2022) review of fungal classification. [11]
The thalli of Lichinaceae species are known to occur in a variety of forms, including gelatinous, crustose, peltate , filamentous to microfoliose or microfruticose, ecorticate (lacking a cortex) and homoiomerous or stratified and very rarely eucorticate (i.e., comprising well-differentiated hyphae). The photobiont partner for the majority of species is cyanobacterial. The form of the ascomata is apotheciate, usually zeorine, immersed or adnate, often pycnoascocarps, rarely thallinocarps. The hamathecium (the hyphae or other tissues between the asci) consist of unbranched to branched paraphyses, amyloid or non-amyloid. Asci are either prototunicate or unitunicate, and either amyloid or non-amyloid. Ascospores are simple, spherical to ellipsoid in shape, hyaline, and non-amyloid. The conidiomata are in the form of pycnidia. The conidia are non-septate, ellipsoid or bacilliform, rarely globose or filiform to sigmoid, and hyaline. No lichen products are made. Most species in the family are saxicolous (rock-dwelling) or terrestrial, while some species are corticolous (bark-dwelling). [12]
As of December 2023 [update] , Species Fungorum (in the Catalogue of Life) accepts 47 genera and 156 species in the family Lichinaceae. [13]
The genus Lichinodium , formerly placed in Lichinaceae, was placed in its own family (Lichinodiaceae) and order (Lichinodiales) in the class Leotiomycetes. [42]
The Roccellaceae are a family of fungi in the order Arthoniomycetes. Most taxa are lichenized with green algae, although some are lichenicolous, growing on other lichens.
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.
The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Lichinales is the sole order of ascomycete fungi in the class Lichinomycetes. It contains three families: Gloeoheppiaceae, Lichinaceae, and Peltulaceae. Most species are lichenized. Lichinales was proposed in 1986 by German lichenologists Aino Henssen and Burkhard Büdel. The class Lichinomycetes was created by Valérie Reeb, François Lutzoni and Claude Roux in 2004.
Gloeoheppiaceae is a family of ascomycete fungi in the order Lichinales. The family contains ten species distributed amongst three genera. Most species are lichenised with cyanobacteria. Species in this family are mostly found in desert areas. Modern molecular phylogenetics analysis casts doubt on the phylogenetic validity of the family, suggesting a more appropriate placement of its species in the family Lichinaceae.
Verrucariaceae is a family of lichens and a few non-lichenised fungi in the order Verrucariales. The lichens have a wide variety of thallus forms, from crustose (crust-like) to foliose (bushy) and squamulose (scaly). Most of them grow on land, some in freshwater and a few in the sea. Many are free-living but there are some species that are parasites on other lichens, while one marine species always lives together with a leafy green alga.
Pannaria is a genus of lichen-forming fungi in the family Pannariaceae. The widespread genus contains an estimated 51 species, found primarily in tropical regions.
Xanthoparmelia is a genus of foliose lichen in the family Parmeliaceae. Xanthoparmelia is synonymous with Almbornia, Neofuscelia, Chondropsis, Namakwa, Paraparmelia, and Xanthomaculina. This genus of lichen is commonly found in the United States, as well as Australia, New Zealand and Ecuador.
Edwardiella is a genus of fungi within the family Lichinaceae. This is a monotypic genus, containing the single species Edwardiella mirabilis. Aino Henssen named the genus after the Prince Edward Islands, the type locality of the type species.
Lempholemma is a genus of lichen-forming fungi in the family Lichinaceae.
Lichinella is a genus of lichen-forming fungi in the family Lichinaceae. It was circumscribed in 1872 by Finnish lichenologist William Nylander. Five species are accepted by Species Fungorum.
Lichinodium is a genus of filamentous lichens. It is the only genus in the family Lichinodiaceae, itself the only member of the order Lichinodiales. Lichinodium has four species. Previously considered part of the class Lichinomycetes, molecular phylogenetic analysis revealed that Lichinodium represents a unique lineage in the Leotiomycetes—the first known group of lichen-forming fungi in this class.
Pyrenopsis is a genus of lichen-forming fungi in the family Lichinaceae. It contains 12 species. The genus was circumscribed by the Finnish lichenologist William Nylander in 1858.
Zahlbrucknerella is a genus of filamentous, rock-dwelling lichens in the family Lichinaceae.
Thyrea is a genus of lichen-forming fungi in the family Lichinaceae. It contains four species that have been accepted by Species Fungorum. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1856, with Thyrea plectospora assigned as the type species.
Peltula is a genus of small dark brown to olive or dark gray squamulose lichens that can be saxicolous ) or terricolous. Members of the genus are commonly called rock-olive lichens. They are cyanolichens, with the cyanobacterium photobiont from the genus Anacystis. They are umbilicate with flat to erect squamule lobes that attach from a central holdfast or cluster of rhizenes. Lichen spot tests are usually negative.
Aino Marjatta Henssen, was a German lichenologist and systematist. Her father, Gottfried Henssen, was a folklorist and her mother was Finnish.
Helge Thorsten Lumbsch is a German-born lichenologist living in the United States. His research interests include the phylogeny, taxonomy, and phylogeography of lichen-forming fungi; lichen diversity; lichen chemistry and chemotaxonomy. He is the Associate Curator and Head of Cryptogams and Chair of the Department of Botany at the Field Museum of Natural History.
Coenogonium is a genus of filamentous lichens in the monotypic family Coenogoniaceae. It has about 90 species. Most species are leaf-dwelling or grow on bark, although a few are known to grow on rocks under certain conditions, and some are restricted to growth on termite nests. The genus was circumscribed in 1820 by German naturalist Christian Gottfried Ehrenberg.
Harpidiaceae is a small family of lichen-forming fungi, containing two genera and five species. It is of uncertain classification in the Pezizomycotina.
