Brefeldia
''Brefeldia'' is an genus of slime molds in the family Amaurochaetaceae. The genus name of ''Brefeldia'' is in honour of Julius Oscar Brefeld (1839 – 1925), a German botanist and mycologist. The genus was circumscribed by Józef Tomasz Rostafínsky in 1873 and appears to be monotypic, containing the species ''Brefeldia maxima ''Brefeldia maxima'' is a species of non-parasitic plasmodial slime mold, and a member of the class Myxogastria, Myxomycetes.

Brefeldia Maxima
''Brefeldia maxima'' is a species of non-parasitic plasmodial slime mold, and a member of the class Myxogastria, Myxomycetes. It is common name, commonly known as the tapioca slime mold because of its peculiar pure white, tapioca pudding-like appearance. A common species with a worldwide distribution, particularly in North America and Europe. It is often found on bark after heavy rain or excessive watering. Their spores are produced on or in aerial sporangia and are spread by wind, however beetles of the family Lathridiidae are also reported to disperse the spores. Bonner states that soil invertebrates and rain mainly disperse spores as they are sticky and unlikely to be carried by air currents. The genus is named after German botanist and mycologist Julius Oscar Brefeld (August 19, 1839 – January 12, 1925). Distribution Found throughout the United Kingdom and common in Europe, ''Brefeldia maxima'' is known to be much rarer in North America. Description and habitat File:Brefe ...

Julius Oscar Brefeld
Julius Oscar Brefeld (19 August 1839 – 12 January 1925), usually just Oscar Brefeld, was a German botanist and mycologist. Biography Brefeld was a native of Telgte. He studied pharmacy in Heidelberg and Berlin, and afterwards served as an assistant to Anton de Bary (1831-1888) at the University of Halle. In 1878 he became a lecturer of botany at the Eberswalde Forestry Academy at Eberswalde, and in 1882 was a professor of botany at the University of Münster, as well as manager of its botanical gardens. In 1898 he succeeded Ferdinand Cohn (1828-1898) as professor at the University of Breslau. In 1898 Brefeld was stricken by glaucoma, and subsequently became totally blind. His eye problems caused him to retire from the university in 1909. Brefeld was a prolific author of works in the field of mycology, being remembered for his writings on the heteroecious nature of fungal rusts and smuts. He pioneered culture techniques in the growth of fungi (using gelatin as a solid me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myxogastria
Myxogastria/Myxogastrea (myxogastrids, International Code of Zoological Nomenclature, ICZN) or Myxomycetes (International Code of Nomenclature for algae, fungi, and plants, ICN), is a Class (biology), class of slime molds that contains 5 order (biology), orders, 14 family (biology), families, 62 genera, and 888 species. They are colloquially known as the ''plasmodial'' or ''acellular'' slime moulds. All species pass through several, very different morphology (biology), morphologic phases, such as microscopic individual cells, slimy amorphous organisms visible with the naked eye and conspicuously shaped fruit body, fruit bodies. Although they are monocellular, they can reach immense widths and weights: in extreme cases they can be up to across and weigh up to . The class Myxogastria is distributed worldwide, but it is more common in temperate regions where it has a higher biodiversity than in polar regions, the subtropics or tropics. They are mainly found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Slime Mold
Slime mold or slime mould is an informal name given to several kinds of unrelated eukaryotic organisms with a life cycle that includes a free-living single-celled stage and the formation of spores. Spores are often produced in macroscopic multicellular or multinucleate fruiting bodies which may be formed through aggregation or fusion. Slime molds were formerly classified as fungi but are no longer considered part of that kingdom. Although not forming a single monophyletic clade, they are grouped within the paraphyletic group Protista. More than 900 species of slime mold occur globally. Their common name refers to part of some of these organisms' life cycles where they can appear as gelatinous "slime". This is mostly seen with the Myxogastria, which are the only macroscopic slime molds. Most slime molds are smaller than a few centimetres, but some species may reach sizes up to several square metres and masses up to 20 kilograms. They feed on microorganisms that live in ...

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. 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 molecular phylogenetics ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...
