Asterophora Parasitica
''Asterophora parasitica'', commonly known as the parasitic Asterophora or the Russula parasite, is a species of fungus that grows as a parasite on other mushrooms. The fruit bodies are small, with silky fibers on the surface of grayish caps and thick, widely spaced gills. Mushrooms fruit in clusters on the decaying remains of ''Lactarius'' and '' Russula'' species, particularly those in the ''Russula nigricans'' group. Found primarily in temperate zones of Europe and North America, the fungus is widespread but not common. Taxonomy Jean Baptiste Francois Pierre Bulliard first described the species as ''Agaricus parasiticus'' in 1791; it was sanctioned under that name by Elias Magnus Fries in his 1822 ''Systema Mycologicum''. Rolf Singer transferred it to ''Asterophora'' in 1951. Synonyms include ''Gymnopus parasiticus'', published by Samuel Frederick Gray in 1821, ''Merulius parasiticus'' by Thomas Purton in 1821, and ''Nyctalis parasitica'' by Elias Fries in 1838. Ac ...

Fungi
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamella (mycology)
In mycology, a lamella, or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, ''Lactarius'' species typically seep latex from their gills. It was originally believed that all gilled fungi were Agaricales, but as fungi were studied in more detail, some gilled species were demonstrated not to be. It is now clear that this is a case of convergent evolution (i.e. gill-like structures evolved separately) rather than being an anatomic feature that evolved only once. The apparent reason that various basidiomycetes have evolved gills i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Carl Joseph Corda
August Carl Joseph Corda (1809–1849) was a Czech physician and mycologist. This botanist is denoted by the author abbreviation when citing a botanical name. Early life and education Corda was born in Reichenberg (now Liberec), Bohemia on November 15, 1809. Corda's father was a textile seller. Both of Corda's parents died suddenly only a few weeks following his birth, and Corda was raised by his grandmother, attending the Normale School in Reichenberg. Corda's grandmother died in 1819 and Corda was sent to live with an "unacquainted family" for two years during which time he did not receive schooling. Two years later, Corda was transferred to the care of an uncle in Prague where he attended the "Lyceum of New Prague". As a result of family difficulties, Corda left the Lyceum in 1824 to attend polytechnical school. There, he studied physics under Franz Ignatz Cassian Hallaschka, chemistry under Josef Johann Steinmann, mineralogy under Franz Xaver Zippe, and botany under Ign ...

James Sowerby
James Sowerby (21 March 1757 – 25 October 1822) was an English naturalist, illustrator and mineralogist. Contributions to published works, such as '' A Specimen of the Botany of New Holland'' or '' English Botany'', include his detailed and appealing plates. The use of vivid colour and accessible texts were intended to reach a widening audience in works of natural history. Biography James Sowerby was born in Lambeth, London, his parents were named John and Arabella. Having decided to become a painter of flowers his first venture was with William Curtis, whose ''Flora Londinensis'' he illustrated. Sowerby studied art at the Royal Academy and took an apprenticeship with Richard Wright. He married Anne Brettingham De Carle and they were to have three sons: James De Carle Sowerby (1787–1871), George Brettingham Sowerby I (1788–1854) and Charles Edward Sowerby (1795–1842), the Sowerby family of naturalists. His sons and theirs were to contribute and continue the enormous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Withering
William Withering Fellow of the Royal Society, FRS (17 March 1741 – 6 October 1799) was an English botanist, geologist, chemist, physician and first systematic investigator of the bioactivity of digitalis. Withering was born in Wellington, Shropshire, Wellington, Shropshire, the son of a surgeon. He trained as a physician and studied medicine at the University of Edinburgh Medical School. He worked at Birmingham General Hospital from 1779. The story is that he noticed a person with edema, dropsy (swelling from congestive heart failure) improve remarkably after taking a traditional herbal remedy; Withering became famous for recognising that the active ingredient in the mixture came from the foxglove plant. The active ingredient is now known as digoxin, after the plant's scientific name. In 1785, Withering published ''An Account of the Foxglove and some of its Medical Uses'', which contained reports on clinical trials and notes on digitalis's effects and Digoxin toxicity, toxici ...

Type (biology)
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

MycoBank
MycoBank is an online database, documenting new mycological names and combinations, eventually combined with descriptions and illustrations. It is run by the Westerdijk Fungal Biodiversity Institute in Utrecht. Each novelty, after being screened by nomenclatural experts and found in accordance with the ICN (International Code of Nomenclature for algae, fungi, and plants), is allocated a unique MycoBank number before the new name has been validly published. This number then can be cited by the naming author in the publication where the new name is being introduced. Only then, this unique number becomes public in the database. By doing so, this system can help solve the problem of knowing which names have been validly published and in which year. MycoBank is linked to other important mycological databases such as ''Index Fungorum ''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Roy ...

Synonym (biology)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia lev ...

Sanctioned Name
In mycology, a sanctioned name is a name that was adopted (but not necessarily coined) in certain works of Christiaan Hendrik Persoon or Elias Magnus Fries, which are considered major points in fungal taxonomy. Definition and effects Sanctioned names are those, regardless of their authorship, that were used by Persoon in his ''Synopsis Methodica Fungorum'' (1801) for rusts, smuts and gasteromycetes, and in Fries's '' Systema Mycologicum'' (three volumes, published 1821–32) and '' Elenchus fungorum'' for all other fungi. A sanctioned name, as defined under article 15 of the ''International Code of Nomenclature for algae, fungi, and plants'' (previously, the ''International Code of Botanical Nomenclature'') is automatically treated as if conserved against all earlier synonyms or homonyms. It can still, however, be conserved or rejected normally. History Because of the imprecision associated with assigning starting dates for fungi sanctioned in Fries' three ''Systema'' volumes ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...
