Hueidea Coeruleofrigida
''Hueidea'' is a fungal genus in the family Teloschistaceae. The type species is '' Hueidea australiensis'', a saxicolous (rock-dwelling), crustose lichen found on granite rocks in the Mount Kosciuszko area of New South Wales, Australia. Both the species and the genus were described as new to science in 2003 by the Australian lichenologists Gintaras Kantvilas and Patrick McCarthy. An additional five species were added to the genus in 2024. Taxonomy ''Hueidea'' was erected in 2003 by Gintaras Kantvilas and Patrick M. McCarthy to accommodate the alpine Australian endemic ''H. australiensis''. On the basis of its thick-walled, (i.e., and lacking ) apothecia and the absence of anthraquinone pigments, the authors placed the genus in the family Fuscideaceae (Umbilicariales), albeit with some reservations. Their cautious assessment reflected the fact that no molecular data were then available. Molecular analyses using various molecular markers published in 2024 demonstrated th ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...

Lichen Genera
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teloschistales Genera
The Teloschistales are an order (taxonomy), order of mostly lichen-forming fungus, fungi belonging to the class (taxonomy), class Lecanoromycetes in the division (mycology), division Ascomycota. According to one 2008 estimate, the order contains 5 Family (biology), 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 containing these two families is itself sister to a clade containing families Brigantiaeaceae and Letrouitiaceae.

The type species is '' Hueidea australiensis'', a saxicolous (rock-dwelling), crustose lichen found on granite rocks in the Mount Kosciuszko area of New South Wales, Australia.

An additional five species were added to the genus in 2024. Taxonomy ''Hueidea'' was erected in 2003 by Gintaras Kantvilas and Patrick M. McCarthy to accommodate the alpine Australian endemic ''H. australiensis''. On the basis of its thick-walled, (i.e., and lacking ) apothecia and the absence of anthraquinone pigments, the authors placed the genus in the family Fuscideaceae (Umbilicariales), albeit with some reservations. Their cautious assessment reflected the fact that no molecular data were then available. Molecular analyses using various molecular markers published in 2024 demonstrated th ...

Soredia
Soredia are common reproduction, reproductive structures of lichens. Lichens asexual reproduction, reproduce asexually by employing simple fragmentation and production of soredia and isidia. Soredia are powdery propagules composed of fungus, fungal hyphae wrapped around cyanobacteria or green algae. These can be either scattered diffusely across the surface of the lichen's thallus, or produced in localized structures called soralia. Fungal hyphae make up the basic body structure of a lichen. The soredia are released through openings in the upper cortex of the lichen structure. After their release, the soredia disperse to establish the lichen in a new location.

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. For example, if we determine that species X, Y, and Z belong in genus A, and species T, U, V, and W belong in genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecu ...
