Lecanoromycetes

Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci (spore-bearing cells) of the Lecanoromycetes most often release spores by rostrate dehiscence.

The Lecanoromycetidae are a subclass of fungi in the class Lecanoromycetes. This subclass contains seven orders.

species of fungus

The Rhizocarpales are an order of lichen-forming fungi in the subclass Lecanoromycetidae of the class Lecanoromycetes. It has two families, Rhizocarpaceae and Sporastatiaceae, which contain mostly crustose lichens.

Thelenellaceae is a family of lichen-forming fungi. It is the sole family in the monotypic order Thelenellales, and contains three genera and about 50 species.

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.

Sporastatia is a genus of crustose lichens in the family Sporastatiaceae. It has four species. Sporastatia lichens are long-lived species that grow on siliceous or weakly calcareous rocks in arctic and alpine locales.

genus of fungi

Sporastatiaceae is a small family of crustose lichens in the order Rhizocarpales. It contains two genera, Sporastatia and Toensbergia, with a total of five species. Sporastatiaceae was circumscribed in 2013 by Mika Bendiksby and Ernst Timdal.

Sarrameanaceae is a family of lichen-forming fungi in the monotypic order Sarrameanales. The family was established in 1984 by Josef Hafellner and contains three genera. These lichens form crust-like growths that often produce powdery reproductive structures for spreading to new locations. They have brown to black fruiting bodies and show remarkable diversity in ascospore shapes, with some species coiling their spores in tight spirals within their reproductive structures.

The Ostropomycetidae are a subclass of mostly lichen-forming fungi in the class Lecanoromycetes. It contains nine orders and 37 families.

Tremolecia is a small genus of lichen-forming fungi in the family Hymeneliaceae. Its two accepted species form thin crusts on rock and are recognised by their dark, cup-shaped fruiting bodies (apothecia). The better-known species, Tremolecia atrata, is widespread on iron-rich rocks in mountainous and arctic regions.

Piccolia is a small genus of crustose lichens in the class Lecanoromycetes. First circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1864, it contains ten species. Due to a lack of molecular data, it has not been assigned to an order or family.

Schaereria is a genus of lichen-forming fungi. It is the sole genus in the family Schaereriaceae, which itself is the only family in the Schaereriales, an order in the subclass Ostropomycetidae of the class Lecanoromycetes. Most Schaereria species are crustose lichens that live on rocks. Schaereria was first proposed by Gustav Wilhelm Körber in 1855 and was later taken up by other lichenologists despite periods of disuse.

Xerotrema is a small genus of fungi in the family Odontotremataceae. It comprises two species. The genus was circumscribed by Martha Allen Sherwood and Brian John Coppins in 1980. The type species, Xerotrema megalospora, is found in the United States and Canada. X. quercicola was added to the genus in 2008. These fungi produce tiny, deeply cup-shaped fruiting bodies on weathered, barkless wood of conifers and hardwoods in temperate regions. While the genus was originally thought to be non-lichenized, at least one species appears to form facultative partnerships with green algae, meaning i

Petractis is a small genus of lichen-forming fungi of uncertain familial and ordinal placement in the Lecanoromycetes. These inconspicuous lichens grow as thin crusts embedded within rock surfaces, partnering with cyanobacteria to form barely visible films that are primarily detected by their small, star-shaped fruiting bodies. The genus contains two species that typically inhabit calcareous rocks, where their fruiting structures create distinctive pits in the stone surface after they decay.

Anzina is a fungal genus of uncertain familial and ordinal classification in the subclass Ostropomycetidae. It is monotypic genus, containing the single crustose lichen species Anzina carneonivea. The lichen occurs mainly in mountainous regions of Europe and western North America, where it grows on the bark of coniferous trees and on decaying organic matter. The genus name honours the Italian botanist Martino Anzi, who first described the species in 1868. The genus was established more than a century later, after microscopic work indicated that the species had a distinctive set of .

Hymenelia is a genus of lichen-forming fungi belonging to the family Hymeneliaceae.

Arthrorhaphis is a genus of fungi in the monotypic family Arthrorhaphidaceae. It has 13 species. Species in this family have a widespread distribution in temperate and montane habitats. They grow symbiotically with green algae, or parasitically on other lichens. These fungi typically start as parasites on other lichens but can later become free-living, forming bright greenish-yellow to greyish scales on acidic soils and weathered rocks in cool upland regions.

Thelenella is a genus of lichen-forming fungi in the family Thelenellaceae. These inconspicuous lichens form thin, crust-like growths that are tightly attached to their substrates and appear as dull whitish, pale grey, or light brown patches. Species of Thelenella are commonly found in damp, shaded environments where they grow on tree bark, living leaves, moss cushions, rock faces, and moss-rich soil. The genus is distinguished by its thick-walled fruiting bodies that are mostly embedded within the lichen crust and contain multicellular spores with multiple cross-walls.

Loxospora is a genus of lichen-forming fungi in the family Sarrameanaceae. The genus was established in 1852 by the Italian lichenologist Abramo Bartolommeo Massalongo and originally included species now placed in other genera. Molecular phylogenetics studies have revealed that several species previously assigned to Loxospora actually belong to a separate lineage, leading to the creation of the new genus Chicitaea in 2024. These lichens form crusty growths on bark and rock surfaces, with some species producing powdery reproductive structures whilst others develop disc-shaped fruiting bodies.

Biatorella is a genus of lichen-forming fungi in the family Biatorellaceae.

Julella is a genus of ascomycete fungi. Most species are non-lichenised, bark-dwelling saprophytes, though some collections appear to be facultatively lichenised with the green alga Trentepohlia. The fungi produce immersed, black, flask-shaped perithecia with a dark . Their asci are double-walled and contain two or eight large, colourless, (multi-chambered) ascospores. Asexual fruiting bodies (pycnidia) produce simple, rod-shaped conidia. No secondary metabolites are known. The genus was introduced by Jean-Henri Fabre in 1879. Modern treatments recognise only a few species, and its family plac
