Geastrum Britannicum
''Geastrum britannicum'' is a fungal species in the family Geastraceae. Its recommended English name is vaulted earthstar. Like other earthstars, the basidiocarps (fruit bodies) are initially globose. Their thick outer skin splits open at maturity to expose the puffball-like spore sac surrounded by the split rays of the outer skin. In the vaulted earthstar, the rays split apart and form an arch, raising the spore sac upwards. Taxonomy ''Geastrum britannicum'' was described in 2015 from England by Spanish mycologist Juan Carlos Zamora, based on a holotype found on a roadside verge in Cockley Cley under pine trees in 2000 by Jonathan Revett, with paratypes from New Milton and Surlingham. The species was already the subject of research at the Royal Botanic Gardens, Kew where more than a dozen additional collections had been studied from England and Wales, the earliest dating back to 1994. The new species had previously been confused with ''Geastrum quadrifidum'' and '' G. fornicatu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Botanic Gardens, Kew
Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Dame Amelia Fawcett. The organisation manages botanic gardens at Kew in Richmond upon Thames in south-west London, and at Wakehurst, a National Trust property in Sussex which is home to the internationally important Millennium Seed Bank, whose scientists work with partner organisations in more than 95 countries.

Geastrum
''Geastrum'' (orthographical variant ''Geaster'') is a genus of puffball-like mushrooms in the family Geastraceae. Many species are known commonly as earthstars. The name, which comes from ''geo'' meaning ''earth'' and meaning ''star'', refers to the behavior of the outer peridium. At maturity, the outer layer of the fruiting body splits into segments which turn outward creating a star-like pattern on the ground. The inner peridium is called a spore sac. In some species, the outer peridium splits from a middle layer, causing the spore sac to arch off the ground. If the outer peridium opens when wet and closes when dry, it is described as hygroscopic. In some species, the inner peridium is borne on a stalk or pedicel. The columella is a column-like clump of sterile tissue found inside the inner peridium. The network of fertile tissue inside the inner peridium, the capillitium, arises from the columella And is where basidia and basidiospores are produced. The mouth in most species ...

British Mycological Society
The British Mycological Society is a learned society established in 1896 to promote the study of fungi. Formation The British Mycological Society (BMS) was formed by the combined efforts of two local societies: the Woolhope Naturalists' Field Club of Hereford and the Yorkshire Naturalists’ Union. The Curator of the Hereford Club, Dr. H. G. Bull, convinced the members in 1867 to undertake the particular study of mushrooms. While the mycological efforts of the Club diminished somewhat after Dr. Bull's death, the Union of Yorkshire founded its Mycological Committee in 1892. This Committee attracted the involvement of many eminent mycologists including George Edward Massee (1845–1917), James Needham (1849–1913), Charles Crossland (1844-1916), and Henry Thomas Soppitt (1843-1899). Mycologist Kathleen Sampson was a member for sixty years, as well as serving as president in 1938. The need for a national organisation and the need for a journal to publish their observatio ...

DNA Sequence
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geastrum Fornicatum
''Geastrum fornicatum'', common name known as the acrobatic earthstar or the arched earthstar, is an inedible species of mushroom in the family ''Geastraceae''. Like other earthstar mushrooms, the thick outer skin splits open at maturity to expose the spore sac to the elements; the specific epithet ''fornicatum'' (Latin for 'arched' or 'vaulted') refers to the arched shape of the rays which extend downwards to rest on the mycelial sac and elevate the spore sac. History When first described in the late 17th century, the species was called ''Fungus anthropomorphus'' due to its resemblance to the human figure. In his 1799 treatise ''Colored Figures of English Fungi or Mushrooms'', English naturalist James Sowerby wrote:So strange a vegetable has surprised many; and in the year 1695 it was published under the name of Fungus Anthropomorphus, and figured with human faces on the head. It is at first roundish; in ripening the head bursts through the two coats or wrappers; the inner wrappe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geastrum Quadrifidum
''Geastrum quadrifidum'', commonly known as the rayed earthstar or four-footed earthstar, is an inedible species of mushroom belonging to the genus ''Geastrum'', or earthstar fungi. First described scientifically by Christian Hendrik Persoon in 1794, ''G. quadrifidum'' is a cosmopolitan—but not common—species of Europe, the Americas, Africa, Asia, and Australasia. The fungus is a saprobe, feeding off decomposing organic matter present in the soil and litter of coniferous forests. The small, tough, fruit bodies are grayish-brown balls that are initially enclosed by a skin, or peridium, made up of four distinct layers of tissue. The outer tissue layer splits to form star-like rays and expose a circular spore case. Inside the spore case is the gleba—fertile spore-producing tissue that is white and firm when young, but becomes brown and powdery in age. The grayish-brown spore case is set on a short, slender stalk, and has a well-defined narrow pore at the top where matu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surlingham
Surlingham is a village and civil parish in the South Norfolk district of Norfolk situated on the Broads in eastern United Kingdom. It lies approximately 6½ miles (10½ km) south-east of Norwich on the south bank of the River Yare between Bramerton and Rockland St Mary. In the 2001 census it contained 266 households and a population of 637, increasing to 725 at the 2011 census. Although Surlingham is part of South Norfolk District, as in other broadland villages those areas of the village adjacent to the river and broads fall into the executive area of the Broads Authority. Toponymy The villages name origin is uncertain. 'Homestead/village of the south Herlingas (= *Herela's people)' or possibly, 'of the Sutherlingas'. In both cases, the point of reference is probably the River Yare. Churches The church of St Mary in Surlingham is one of 124 existing round-tower churches in Norfolk. The adjacent Church Marsh nature reserve is leased by the RSPB and is overlooked by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

New Milton
New Milton is a market town in southwest Hampshire, England. To the north is in the New Forest and to the south the coast at Barton-on-Sea. The town is equidistant between Lymington and Christchurch, 6 miles (10 km) away. History New Milton dates back to Anglo-Saxon times, and encompasses Old Milton, Barton on Sea, Ashley, Bashley, and Wootton. It is recorded as having a population of 25,717 in the 2011 census. Milton The manor of ("Mildeltune") is listed in the Domesday Book of 1086 and literally means "Middle farm." It was part of the lands belonging to Hugh de Port, and the estate was held from him by William Chernet.William Page (editor), 1912''A History of the County of Hampshire: Volume 5'' Victoria County History The Chernet family maintained possession of Milton into the 13th century, although lesser families were managing the estate on their behalf. The most important of these were the Chaucombe (or Chalcombe) family, who were probably the first people ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paratypes
In zoology and botany, a paratype is a specimen of an organism that helps define what the scientific name of a species and other taxon actually represents, but it is not the holotype (and in botany is also neither an isotype nor a syntype). Often there is more than one paratype. Paratypes are usually held in museum research collections. The exact meaning of the term ''paratype'' when it is used in zoology is not the same as the meaning when it is used in botany. In both cases however, this term is used in conjunction with ''holotype''. Zoology In zoological nomenclature, a paratype is officially defined as "Each specimen of a type series other than the holotype.", ''International Code of Zoological Nomenclature'' In turn, this definition relies on the definition of a "type series". A type series is the material (specimens of organisms) that was cited in the original publication of the new species or subspecies, and was not excluded from being type material by the author (th ...
