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 ...

William Hudson (botanist)
William Hudson FRS (1730 in Kendal – 23 May 1793) was a British botanist and apothecary based in London. His main work was ''Flora Anglica'', published in 1762. He was elected a fellow of the Royal Society in 1761. Life and work Hudson was born between 1730 and 1732 at the White Lion Inn, Kendal, which was kept by his father. He was educated at Kendal grammar school, Hudson was subsequently apprenticed to an apothecary in London. He obtained the prize for botany given by the Apothecaries' Company which was a copy of Ray's ''Synopsis''. However, he also paid attention to mollusca and insects and in Pennant's '' British Zoology'' he is mentioned as the discoverer of '' Trochus terrestris''. From 1757 to 1768 Hudson was resident sub-librarian of the British Museum, and his studies in the Sloane herbarium enabled him to adapt the Linnean nomenclature to the plants described by Ray far more accurately than did John Hill in his ''Flora Britannica'' of 1760. In 1761 Hudson w ...

Thallus
Thallus (plural: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thallodal, thalliform, thalline, or thallose. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Even though thalli do not have organized and distinct parts (leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where ...

Taxa Named By William Hudson (botanist)
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 intr ...

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 ...

Dibaeis Baeomyces
''Dibaeis baeomyces'', commonly known as pink earth lichen, is a fruticose lichen belonging to the family Icmadophilaceae. Taxonomy Carl Linnaeus the Younger described the pink earth lichen in his 1782 work ''Supplementum Plantarum'' as ''Lichen baeomyces''. The genus ''Dibaeis '' was previously considered a synonym of genus ''Baeomyces'', until genetic testing established that the genera were separate and not even especially closely related. ''D. baeomyces'' was one of the species which had its rDNA sequenced by both the 1997 study by Stenroos and DePriest published in the '' American Journal of Botany'', and the 1999 study by Platt and Spatafora published in ''The Lichenologist'', which both established the genera as genetically and morphologically distinct. ''D. baeomyces'' was, however, found to belong to a clade that also includes ''Siphula ceratites'' and ''Thamnolia vermicularis''. ''Baeomyces rufus'', in particular, was noted as having been determined to be phylogenetic ...

Apothecia
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks of ...

Rebentisch
Juliane Rebentisch (born 1970, Bonn) is a German philosopher and art historian whose research focuses on the history and politics of aesthetics. She is the author of three books: ''Aesthetics of Installation Art'' (Sternberg, 2003), ''The Art of Freedom: On the Dialectics of Democratic Existence'' (Polity, 2012), and ''Theorien der Gegenwartskunst'' (Junius, 2013), and has edited numerous volumes on aesthetics, ethics, and political philosophy in both German and English.

DNA Sequencing
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ...
