Varicellaria is a genus of crustose lichens. It is the only genus in the family Varicellariaceae. [2]
The genus Varicellaria was circumscribed by Finnish lichenologist William Nylander in 1858, with Varicellaria microsticta assigned as the type species. [3] [4]
The family Varicellariaceae, containing only the type genus Varicellaria, was informally proposed by Brendan Hodkinson, Richard Harris, and James Lendemer in 2011. [5] H. Thorsten Lumbsch and Steven Leavitt formally published the family in 2018. [6] However, the taxon was not validly published because "an identifier issued by a recognized repository was not cited in the protologue", contrary to rules of botanical nomenclature. [7] This nomenclatural oversight was rectified later the same year in a separate publication. [8]
Characteristics of the family Varicellariaceae are similar to those of its genus. These are: a crustose thallus, unicellular green algal photobionts from genus Trebouxia , ascomata in the form of disc-like apothecia, non-amyloid gel in the hymenium, strongly amyloid, one- or two-spored asci, and hyaline, thick-walled, one-layered, one- or two-celled ascospores. [6]
Collectively, the species in genus Varicellaria have a cosmopolitan distribution. [4]
The Peltigeraceae are a family of lichens in the order Peltigerales. The Peltigeraceae, which contains 15 genera and about 600 species, has recently (2018) been emended to include the families Lobariaceae and Nephromataceae. Many Peltigeraceae species have large and conspicuous, leathery thalli. They largely occur in cool-temperate to tropical montane climates. Tripartite thalli involving fungus, green algae and cyanobacteria are common in this family.
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 Teloschistales are an order of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. According to one 2008 estimate, the order contains 5 families, 66 genera, and 1954 species. The predominant photobiont partners for the Teloschistales are green algae from the genera Trebouxia and Asterochloris.
The Baeomycetales are an order of mostly lichen-forming fungi in the subclass Ostropomycetidae, in the class Lecanoromycetes. It contains 8 families, 33 genera and about 170 species. As a result of molecular phylogenetics research published in the late 2010s, several orders were folded into the Baeomycetales, resulting in a substantial increase in the number of taxa.
The Graphidaceae are a family of lichen-forming fungi in the order Graphidales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark.
The Agyriaceae are a family of lichenized fungi in the order Pertusariales. It contains two genera: Agyrium, and Miltidea. The family was circumscribed by August Carl Joseph Corda in 1838.
Gymnographopsis is a genus of lichen-forming fungi in the family Redonographaceae.
Fissurina is a genus of lichenized fungi in the family Graphidaceae. It has about 160 species, most of which are found in tropical regions.
Cladia is a genus of lichen-forming fungi in the family Cladoniaceae. Cladia species have a crustose or squamulose (scaly) primary thallus and a fruticose, secondary thallus, often referred to as pseudopodetium. The type species of the genus, Cladia aggregata, is widely distributed, occurring in South America, South Africa, Australasia and South-East Asia to southern Japan and India. Most of the other species are found in the Southern Hemisphere.
Diploschistes is a genus of lichen-forming fungi in the family Graphidaceae. Members of the genus are crustose lichens with a thick, cracked (areolate) body (thallus) with worldwide distribution. The fruiting part (apothecia) are immersed in the thick thallus so as to have the appearance of being small "craters". The widespread genus contains about 43 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.
Neoprotoparmelia is a genus of crustose lichens that was created in 2018. It contains 24 tropical and subtropical species that mostly grow on bark. Neoprotoparmelia is in the subfamily Protoparmelioideae of the family Parmeliaceae, along with the morphologically similar genera Protoparmelia and Maronina.
Trichotheliaceae is a family of lichen-forming fungi in the order Gyalectales. The family was circumscribed by Friedrich von Schilling and Friedrich August Georg Bitter in 1927.
Trapeliaceae is a family of lichens in the order Baeomycetales. The family contains 12 genera and about 125 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.
Leprocaulaceae is a family of mostly lichen-forming fungi. It is the single family in the monotypic order Leprocaulales. Leprocaulaceae contains three genera and about 33 species.
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.
Sarrameanaceae is a family of lichen-forming fungi in the monotypic order Sarrameanales. It contains two genera, Loxospora, and Sarrameana, the type genus. The family was circumscribed by Josef Hafellner in 1984. The order Sarrameanales was proposed by Brendan Hodkinson and James Lendemer in 2011, as they had noted that previously published large-scale molecular phylogenetic studies had shown that the group of species contained in the family Sarrameanaceae were distinct and separate from the clade containing all of the other orders of the Ostropomycetidae. However, the name Sarrameanales was not validly published according to the rules of botanical nomenclature, because it was not accompanied by a suitable description. Despite this, the order continues to be used in lichenological literature.
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.
Graphidales is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 6 families, about 81 genera and about 2,228 species. Family Graphidaceae are the largest crustose family within Graphidales order comprising more than 2000 species, which are widely distributed in tropical and subtropical regions of the world.
