Hypocenomyce is a genus of lichen-forming fungi in the family Ophioparmaceae. [1] Species in the genus grow on bark and on wood, especially on burned tree stumps and trunks in coniferous forest. Hypocenomyce lichens are widely distributed in the northern hemisphere. [2]
The genus was circumscribed in 1951 by French lichenologist Maurice Choisy to contain the single species Hypocenomyce scalaris , [3] a lichen that was first formally described by Erik Acharius in 1795. Choisy's original concept of the genus featured a squamulose thallus, adnate apothecia of the lecideine type (i.e., lacking algae and an amphithecium, with a black carbonized margin as in the genus Lecidea ) and pycnoconidia that are short, straight, and cylindrical. [3] Norwegian lichenologist Einer Timdal revised the genus in 1984, describing two new species to bring the total Hypocenomyce species up to ten. [4] Since then, two new species have been described, and several have been transferred to other genera.
Norwegian lichenologist Einar Timdal revised the genus in the mid-1980s and identified four evolutionary groups; he suggested that the genus was polyphyletic. [4] A 2013 molecular phylogenetic study clarified the phylogenetic relationships amongst species previously classified in the genus. It was shown that the genus–as then circumscribed–consisted of seven clades belonging to different genera, families, orders and even subclasses. Based on these results, the genus was split into different genera – Carbonicola , Fulgidea , and Hypocenomyce. [2] The Hypocenomyce xanthococca species group, which had been previously raised to the level of genus as Pycnora , [5] was further split into Pycnora and Toensbergia . [2]
Species previously classified in Hypocenomyce include:
The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.
Xylographa is a genus of lichenized fungi in the family Xylographaceae.
Trapeliopsis is a genus of lichenized fungi in the family Trapeliaceae. It contains 20 species. The genus was circumscribed in 1980 by Hannes Hertel and Gotthard Schneider, with Trapeliopsis wallrothii designated as the type species.
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.
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.
Cratiria is a genus of lichen-forming fungi in the family Caliciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 20 species. The genus was circumscribed by Austrian lichenologist Bernhard Marbach in 2000, with Cratiria lauri-cassiae assigned as the type species.
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.
Eremastrella is a genus of lichen in the family Lecideaceae. The genus was circumscribed by lichenologist Stefan Vogel in 1955, with Eremastrella tobleri assigned as the type species.
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.
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.
Bibbya is a genus of fruticose lichens in the family Ramalinaceae.
Toensbergia is a genus of lichen-forming fungi in the family Sporastatiaceae. The genus was circumscribed by Mika Bendiksby and Einar Timdal in 2013. The genus name honours Norwegian lichenologist Tor Tønsberg, "in appreciation of his important work on sorediate, corticolous lichens". The type species is Toensbergia leucococca, which was formerly classified in genus Hypocenomyce, presumably due to its resemblance to Hypocenomyce xanthococca.
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.
Carbonicola is a small genus of lichen-forming fungi. It is the sole genus in the monogeneric family Carbonicolaceae. The genus, which collectively has an almost cosmopolitan distribution, contains three squamulose lichens that prefer to grow on burned wood in temperate areas of the world.
Strangospora is a genus of lichen-forming fungi. It is the only genus in the family Strangosporaceae, which itself is of uncertain taxonomic placement in the Ascomycota. It contains 10 species.
Martinjahnsia is a single-species fungal genus in the family Teloschistaceae. It contains the sole species Martinjahnsia resendei, a saxicolous (rock-dwelling) crustose lichen.
Xanthoria yorkensis is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. Found in South Australia, it was formally described as a new species in 2009 by lichenologists Sergey Kondratyuk and Ingvar Kärnefelt. The type specimen, collected along the Maitland road in Yorke Peninsula, was found growing on Melaleuca trees in mallee scrub. The species epithet refers to its type locality, the only place the lichen is known to occur. Kondratyuk and colleagues proposed to transfer the taxon to the newly circumscribed Jackelixia in 2009, but this genus has not been widely accepted by other authorities.
Xanthoria kangarooensis is a species of corticolous (bark-dwelling), crustose lichen in the family Teloschistaceae. Found in Australia, it was formally described as a new species in 2009 by lichenologists Sergey Kondratyuk and Ingvar Kärnefelt. The type specimen was collected from East Kangaroo Island, where it was found growing on dead Lycium ferocissimum shrubs. Other associated lichens include species of Pyxine, Ramalina, and Rinodina. The species epithet kangarooensis refers to its type locality, the only place the lichen is known to occur. Kondratyuk and colleagues proposed to transfer the taxon to the newly circumscribed Jackelixia in 2009, but this genus has not been widely accepted by other authorities.
