Lecidella is a genus of crustose lichens in the family Lecanoraceae.
Lecidella was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855. [2] It was not widely used until more than a century later, when Hannes Hertel recognized it first as a subgenus of Lecidea, [3] and then a couple of year after as a distinct genus. [4]
A phylogenetic analysis of the genus using 11 species (mostly from China) found that Lecidella species fall into three major clades, which were proposed as three informal groups: Lecidella stigmatea group, L. elaeochroma group and L. enteroleucella group. [5]
Lecidella species have a thallus that is crustose, and biatorine , meaning that it resembles the genus Biatora –having a proper exciple, which is not coal-black ( carbonised , but coloured or blackening. It has eight-spored asci of the Lecidella type. The ascospores are simple and hyaline, while the conidia are curved and threadlike. [6]
Morphologically similar genera include Japewiella , Carbonea , and Tasmidella . [7]
Lecidella was estimated to contain about 80 species in a popular 2008 text, [8] a number that was used in a (2020) survey of fungal classification. [9] As of December 2023 [update] , Species Fungorum (in the Catalogue of Life) accepts 39 species in the genus. [10]
The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Trapelia is a genus of lichenized fungi in the family Trapeliaceae.
Sarcogyne is a genus of crustose lichens in the family Acarosporaceae. It was circumscribed by German botanist Julius von Flotow in 1850. A proposal has been put forth in 2021 to assign Sarcogyne clavus as the type species of the genus, "as it represents the original concept of Sarcogyne as having melanized lecideine apothecia without algae in the margin".
Micarea is a genus of lichenized fungi in the family Pilocarpaceae. The widely distributed genus contains 126 species and new species are described actively. Species in the genus are crustose lichens and their photobiont is a single-celled green alga.
Amandinea is a genus of lichenized fungi in the family Caliciaceae. Genetic studies indicates that the genus Amandinea and Buellia are the same, although this is not widely accepted.
Thelidium is a genus of lichen-forming fungi in the family Verrucariaceae. The genus was circumscribed in 1855 by Italian lichenologist Abramo Bartolommeo Massalongo, who assigned Thelidium amylaceum as the type species.
Carbonea is a genus of fungi in the family Lecanoraceae. Most of the species grow on lichens. The genus is widespread, and contains 20 species. Carbonea was originally circumscribed as a subgenus of Lecidea in 1967 before it was promoted to generic status in 1983.
Pyrrhospora is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855, with Pyrrhospora quernea assigned as the type species.
Ramboldia is a genus of lichen-forming fungi in the family Ramboldiaceae. The genus was circumscribed in 1994 by Gintaras Kantvilas and John Alan Elix. It was emended in 2008 by the inclusion of Pyrrhospora species containing the anthraquinone russulone in their apothecia and having a prosoplectenchymatous exciple. The family Ramboldiaceae was circumscribed in 2014 to contain the genus.
Candelariella is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with Candelariella vitellina assigned as the type species.
Porpidia is a genus of crustose lichens in the family Lecideaceae.
Rhizocarpon is a genus of crustose, saxicolous, lecideoid lichens in the family Rhizocarpaceae. The genus is common in arctic-alpine environments, but also occurs throughout temperate, subtropical, and even tropical regions. They are commonly known as map lichens because of the prothallus forming border-like bands between colonies in some species, like the common map lichen.
Fuscidea is a genus of crustose lichens in the family Fuscideaceae. It has about 40 species. The genus was circumscribed in 1972 by lichenologists Volkmar Wirth and Antonín Vězda, with Fuscidea aggregatilis assigned as the type species.
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.
Lecidella mandshurica is a species of corticolous (bark-dwelling), crustose lichen in the family Lecanoraceae. It is found in the Russian Far East, South Korea, and China.
Hannes Hertel is a German botanist and taxonomist and was Director of the State Herbarium in Munich, Germany 1992–2004. His specialist areas are the fungi and lichens.
