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 group is monophyletic In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent co ... (composed only of all the descendants of a common ancestor). Genera of uncertain placement There are several genera in the Lecanoromycetes that have not been placed into any order or family. These are: *'' Argopsis'' – 1 sp. *'' Ascographa'' – 1 sp. *'' Bartlettiella'' – 1 sp. *'' Bouvetiella'' – 1 sp. *'' Buelliastrum'' – 2 spp. *'' Haploloma'' – 1 sp. *'' Hosseusia'' – 3 spp. *'' Korfiomyces'' – 1 sp. *'' Maronella'' – 1 sp. *'' Notolecidea'' – ...

Graphidales
Graphidales is an order (biology), order of lichen-forming fungi in the class Lecanoromycetes. It contains 6 family (biology), families, about 81 genus, 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. History The Graphidales were introduced in a 1884 publication by Frigyes Ákos Hazslinszky in Magyar Birodalom Zuzmó-Flórája on page 216 as family Graphideae. In 1907, they were established as an Order (biology), order by American botanist Charles Edwin Bessey, Bessey (1845–1915), When the order was introduced, it contained just two families, the Graphidaceae and Thelotremataceae who were both mainly tropical based and each family had about 800–1000 species. Sherwood in 1977 proposed to maintain a distinction between the Graphidales with mostly lichenised members and the Ostropales which included mostl ...

Baeomycetales
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. Taxonomy The family Baeomycetaceae was originally proposed by Barthélemy Charles Joseph Dumortier in 1829 (under the spelling ''Baeomyceae''); he included two genera, ''Baeomyces'' and ''Calicium''. Baeomycetaceae was initially classified in the Lecanorales, and Baeomycetaceae and Cladoniaceae were thought to be closely related, sharing a phylogenetic origin in Lecideaceae. It was transferred to the order Helotiales based on the structure of its ascus, which is similar to those in genus '' Leotia''. However, the Helotiales consists of mostly non-lichenised fungi. The first DNA studies conducted with ''Baeomyces' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rhizocarpales
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. Taxonomy The order was originally proposed by the lichenologists Jolanta Miądlikowska and Francois Lutzoni in 2007, following a molecular phylogenetic analysis of the Lecanoromycetes. However, the name was not validly published according to article 32.1(d) of the International Code of Nomenclature for algae, fungi, and plants, because it was not "accompanied by a description or diagnosis or by a reference to a previously and effectively published description or diagnosis". The same authors published the name validly in 2016. In 2017, Pradeep Divakar and colleagues used a then-recently developed "temporal phylogenetic" approach to identify temporal bands for specific taxonomic ranks in the Lecanoromycetes, suggesting that groups of species that diverged within th ...

Schaereriales
''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. Distinctive characteristics of species in the ''Schaereria'' genus include a crustose to squamulose thallus, ascomata (fruiting bodies) with a blackened ring and a blackish , and asci (spore-bearing cells) that lack (a thickened part of the inner wall near the tip). The secondary chemistry of the genus produces specific substances, including the pigment known as in '' Schaereria cinereorufa''. The genus, having a cosmopolitan distribution, primarily favours cold to cool climates of the Northern Hemisphere. However, certain species have been i ...

Sarrameanales
Sarrameanaceae is a family of lichen-forming fungi in the monotypic order Sarrameanales. It contains the genera '' Loxospora'' and '' Sarrameana'', the type genus. The genus '' Chicitaea'' was proposed in 2024 to contain ''Loxospora'' species containing 2'-''O''-methylperlatolic acid. 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. Sarrameanales is in the Ostropomycetidae; within this ...

Agyriales
The Pertusariales are an order of fungi in the class Lecanoromycetes, comprising 8 families, 31 genera, and over 600 species, many of which form lichens. This diverse group is characterized by complex taxonomic history and ongoing phylogenetic revisions. Originally proposed by Maurice Choisy in 1949 and later formally published by the lichenologists David L. Hawksworth and Ove Eriksson in 1986, Pertusariales has undergone significant reclassification due to molecular phylogenetics studies. The order includes well-known genera such as ''Pertusaria'' and ''Ochrolechia'', as well as families like Megasporaceae and Icmadophilaceae. Pertusariales species exhibit a wide range of morphological features and ecological roles, from non-lichenized fungi to various forms of lichen symbioses. The order's taxonomy has been subject to considerable debate and revision, with recent research leading to the establishment of new orders and the reassignment of some taxa. This ongoing refinement re ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Candelariales
The Candelariales are an order of fungi in the monotypic class Candelariomycetes. It contains the families Candelariaceae and Pycnoraceae. The order was circumscribed by Jolanta Miadlikowska, François Lutzoni, and Helge Thorsten Lumbsch as part of a comprehensive phylogenetic classification of the kingdom Fungi published in 2007. The class Candelariomycetes was proposed in 2018 by Hermann Voglmayr and Walter Jaklitsch. Taxonomy The yellow "candle-wax" lichens now grouped in Candelariomycetes were long treated as part of the large class Lecanoromycetes. A multigene study of lichen-forming fungi published in 2007 first recognised them as a distinct order, Candelariales – comprising the families Candelariaceae and Pycnoraceae – but still left the group inside Lecanoromycetes. Even earlier, Miądlikowska and co-workers had informally coined the name "Candelariomycetidae" (2006) for this lineage, and Lücking and colleagues later formalised that name at subclass rank (2017). ...

Teloschistales
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''. Molecular phylogenetics The higher-level phylogenetic relationships of the Teloschistales and other members of the two major subclasses of Lecanoromycetes, Lecanoromycetidae and Ostropomycetidae, were clarified in a 2018 publication by Kraichak and colleagues. In the Teloschistales, the family Teloschistaceae has a sister taxon relationship with Megalosporaceae, and the clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants.

Gyalectales
''Gyalectales'' is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 5 families, 18 genera and about 550 species. Taxonomy The Gyalectales were introduced in a 1974 publication by Aino Henssen and Martin Jahns, but not formally published until 1986 by David Hawksworth and Ove Eriksson. Phylogeny An early (2002) phylogenetics study showed that the order Ostropales, as was then circumscribed, was paraphyletic, and proposed that the Ostropales sensu lato included the Gyalectales and Trapeliaceae. Although they had traditionally been considered to be only distantly related, molecular studies suggested a much closer phylogenetic relationship. As a result, of the molecular data, Kauff and Lutzoni subsumed the Gyalectales into the Ostropales, as the latter name was published earlier (1932 vs. 1986). In 2018, Kraichak and colleagues used a recently developed "temporal phylogenetic" approach to identify temporal bands for specific taxonomic ranks. Based on t ...

Peltigerales
Peltigerales is an order (biology), order of lichen-forming fungus, fungi belonging to the class (taxonomy), class Lecanoromycetes in the division (mycology), division Ascomycota. The taxonomy of the group has seen numerous changes; it was formerly often treated as a suborder of the order Lecanorales. It contains two suborders, eight family (biology), families and about 45 genus, genera such as ''Lobaria'' and ''Peltigera''. The fungi form lichens in a symbiosis, symbiotic relationship with one or two photosynthesis, photosynthetic partners which may be a cyanobacterium such as ''Nostoc'' or a green alga such as ''Coccomyxa''. The majority of species contain just a cyanobacterium, a smaller number have both a cyanobacterium and a green alga while only a few species have just a green alga. The thallus of the lichen may be foliose (leafy), subfruticose (somewhat shrubby) or granular-squamulose (scaly). The thallus attaches to a surface by means of small root-like rhizines. In some s ...
