Baeomycetales Genera
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 ''Baeomyce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baeomyces Rufus
''Baeomyces rufus'', commonly known as the brown beret lichen, is a fruticose lichen belonging to the cap lichen family, Baeomycetaceae. The species was first described by J.F Rebentisch in 1804. Like other lichens, it is a symbiosis between a fungus and an alga. Taxonomy William Hudson described this species as ''Lichen rufus'' in 1762. The similar-appearing lichen ''D. baeomyces'' was formerly identified as ''Baeomyces roseus''; it was not until 1997 that a study by Soili Stenroos and Paula DePriest used DNA sequencing to establish that the species now called ''Dibaeis baeomyces'' did not belong to the genus ''Baeomyces''. ''B. rufus'' was the lichen representing genus ''Baeomyces'' whose DNA was sequenced for comparison with ''B. roseus''/''D. baeomyces''. Description ''B. rufus'' is characterized by bulbous apothecia which may vary from reddish brown to orange to pink, and which become translucent when wet; they may reach a maximum diameter of 2 mm, atop stalks no tal ...

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. Genera of uncertain placement The are several genera in the Lecanoromycetes that have not been placed into any order or family.

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 taxonomic ...

Leotia
''Leotia'' is a genus of cup fungi of the division Ascomycota. ''Leotia'' species are globally distributed, and are believed to be ectomycorrhizal. They are commonly known as ''jelly babies'' because of the gelatinous texture of their fruiting bodies. Biology ''Leotia'' species are characterized by their capitate ascocarps. Within the class Leotiomycetes, ''Leotia'' species produce large fruiting bodies; their long-stalked apothecia bear a fertile layer of asci that covers the upper surface of a mushroom-like cap. ''Leotia'' is closely related to ''Microglossum'', another genus characterized by capitate ascocarps. The species of ''Leotia'' have traditionally been defined largely by the fresh color of the ascocarps (tan in ''L. lubrica'', olive-green in ''L. atrovirens'', and green-headed with a yellow stalk in ''L. viscosa''). However, a molecular phylogenetic study revealed that color is a poor predictor of species affiliation, suggesting further study is needed to develop ne ...

Helotiales
Helotiales is an order of the class Leotiomycetes within the division Ascomycota. The taxonomy within Helotiales has been debated. It has expanded significantly as genomic techniques for taxonomical identification have become more commonly used. , the order is estimated to contain 30 accepted families, 519 genera, and 6266 species. Helotiales is the largest order of non-stromatic discomycetes that usually, but not always, have brightly coloured apothecia. Many members of the family have obviously cup-shaped ascomata with little or no stipes. They are usually found fruiting on coarse or large wood debris as well as on other organic matter. Part of these discomycetes are limited to a specific host range, this goes as far as to not just being limited to one particular plant, additionally some species need a particular part of that plant. Description *Helotiales is distinguished by its disc or cup-shaped apothecia. *Its asci are only slightly thickened in contrast to other Leot ...

Cladoniaceae
The Cladoniaceae are a family of lichenized fungi in the order Lecanorales. It is one of the largest families of lichen-forming fungi, with about 560 species distributed amongst 17 genera. The reindeer moss and cup lichens (''Cladonia'') belong to this family. The latter genus, which comprises about 500 species, forms a major part of the diet of large mammals in taiga and tundra ecosystems. Many Cladoniaceae lichens grow on soil, but other can use decaying wood, tree trunks, and, in a few instances, rocks as their substrate. They grow in places with high humidity, and cannot tolerate aridity. Many Cladoniaceae species are characterized by a thallus that has two distinct forms: a scaly or crust-like primary thallus that, depending on the species, can be permanent or temporary, and a secondary fruticose thallus called a podetium or pseudopodetium. Cladoniaceae members form symbiotic associations with green algae from the class Trebouxiophyceae, usually the genus '' Asterochloris' ...

Calicium
''Calicium'' is a genus of leprose lichens. It is in the family Caliciaceae. The sexual reproduction structures are a mass of loose ascospores that are enclosed by a cup shaped exciple sitting on top of a tiny stalk, having the appearance of a dressmaker's pin (called a mazaedium), hence the common name pin lichen.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, They are also commonly called stubble lichens. They have been used as indicator species for old growth redwood forests. Evolutionary history The discovery of a ''Calicium''-like fossil in Baltic amber dating back 55–35 myr indicates that the main distinguishing characteristics of this genus have persisted for at least tens of millions of years. A fossil-calibrated phylogeny that includes this fossil suggests that the family Caliciaceae diversified from its most recent common ancestor 103–156 Myr ago in the early Cretaceous.

Barthélemy Charles Joseph Dumortier
Barthélemy Charles Joseph Dumortier (; 3 April 1797 in Tournai – 9 July 1878) was a Belgian who conducted a parallel career of botanist and Member of Parliament. Biography Barthélemy Dumortier was a son of the merchant and city councillor Barthélemy-François Dumortier and of Mariue-Jeanne Willaumez. He married Philippine Ruteau and they had a son, Barthélemy-Noël Dumortier (1830-1915). Barthélemy-Charles became politically active in the early eighteen twenties. In 1824 he founded the ''Courrier de l'Escaut'', a paper critical of the government. He adhered in 1830 to the Belgian revolution. In 1831 he became a member of the first elected parliament of the new kingdom, as the member for Tournai. He remained elected until 1847. He then switched seats, and was now elected for the city of Roulers and held this seat until his death. In 1872 he was awarded the honorary title of Minister of State. He also was awarded nobility with the title of earl. However, for unknown reason ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
