Ramaria Formosa
''Ramaria formosa'', commonly known as the salmon coral, beautiful clavaria, handsome clavaria, yellow-tipped- or pink coral fungus, is a coral fungus found in Asia, Europe and North America. It is widely held to be mildly poisonous if consumed, giving rise to acute gastrointestinal symptoms of nausea, vomiting, diarrhea and colicky pain. It is a pinkish, much-branched coral-shape reaching some high. Some forms collected in North America often lack the bitter taste common to European specimens and may represent a different species. Taxonomy The fungus was initially described by Christian Hendrik Persoon in 1797 as ''Clavaria formosa''. In 1821, Elias Magnus Fries sanctioned the genus name ''Clavaria'', and treated ''Ramaria'' as a section of ''Clavaria''. It was placed in its current genus by French mycologist Lucien Quélet in 1888. Synonyms have resulted from transfers of the fungus to the now obsolete genera ''Merisma'' by Harald Othmar Lenz in 1831, and to ''Corallium'' by ...

Christian Hendrik Persoon
Christiaan Hendrik Persoon (1 February 1761 – 16 November 1836) was a German mycologist who made additions to Linnaeus' mushroom taxonomy. Early life Persoon was born in South Africa at the Cape of Good Hope, the third child of an immigrant Pomeranian father and Dutch mother. His mother died soon after he was born; at the age of thirteen his father (who died a year later) sent him to Europe for his education. Education Initially studying theology at Halle, at age 22 (in 1784) Persoon switched to medicine at Leiden and Göttingen. He received a doctorate from the "Kaiserlich-Leopoldinisch-Carolinische Deutsche Akademie der Naturforscher" in 1799. Later years He moved to Paris in 1802, where he spent the rest of his life, renting an upper floor of a house in a poor part of town. He was apparently unemployed, unmarried, poverty-stricken and a recluse, although he corresponded with botanists throughout Europe. Because of his financial difficulties, Persoon agreed to do ...

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested par ...

Ramaria Largentii
The genus ''Ramaria'' comprises approximately 200 species of coral fungi. Several, such as ''Ramaria flava'', are edible and picked in Europe, though they are easily confused with several mildly poisonous species capable of causing nausea, vomiting and diarrhea; these include '' R. formosa'' and '' R. pallida''. Three ''Ramaria'' species have been demonstrated to contain a very unusual organoarsenic compound homoarsenocholine. Etymology The genus name is derived from Latin ''rāmus'' meaning ''branch''. Description Basidiocarps may range in color from bright yellow, red, or orange, to purple, white, and shades of tan. Color changes after bruising occur in some species. The spores of ''Ramaria'' species are yellow-brown to rusty-brown in mass deposit and range from smooth to warted to echinulate or striate; spore size may range considerably, and ornamentation, when present, is cyanophilous. Classification Hjomsköld was the first to introduce the name ''Ramaria'' in 1790. Persoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramaria Aurea
''Ramaria aurea'' is a coral mushroom in the family Gomphaceae. It is found in North America and Europe. It is similar to '' R. flava''; both species are edible An edible item is any item that is safe for humans to eat. "Edible" is differentiated from "eatable" because it does not indicate how an item tastes, only whether it is fit to be eaten. Nonpoisonous items found in nature – such as some mushroo ....

Chemical Tests In Mushroom Identification
Chemical tests in mushroom identification are methods that aid in determining the variety of some fungi. The most useful tests are Melzer's reagent and potassium hydroxide. Ammonia Household ammonia can be used. A couple of drops are placed on the flesh. For example, '' Boletus spadiceus'' gives a fleeting blue to blue-green reaction. Iron salts Iron salts are used commonly in ''Russula'' and Bolete identification. It is best to dissolve the salts in water (typically a 10% solution) and then apply to the flesh, but it is sometimes possible to apply the dry salts directly to see a color change. For example, the white flesh of ''Boletus chrysenteron'' stains lemon-yellow or olive. Three results are expected with the iron salts tests: no change indicates a negative reaction; a color change to olive, green or blackish green; or a color change to reddish-pink. Meixner test for amatoxins The Meixner test (also known as the Wieland test) uses concentrated hydrochloric acid and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clamp Connection
A clamp connection is a hook-like structure formed by growing hyphal cells of certain fungi. It is a characteristic feature of Basidiomycetes fungi. It is created to ensure that each cell, or segment of hypha separated by septa (cross walls), receives a set of differing nuclei, which are obtained through mating of hyphae of differing sexual types. It is used to maintain genetic variation within the hypha much like the mechanisms found in crozier (hook) during sexual reproduction. Formation Clamp connections are formed by the terminal hypha during elongation. Before the clamp connection is formed this terminal segment contains two nuclei. Once the terminal segment is long enough it begins to form the clamp connection. At the same time, each nucleus undergoes mitotic division to produce two daughter nuclei. As the clamp continues to develop it uptakes one of the daughter (green circle) nuclei and separates it from its sister nucleus. While this is occurring the remaining nuclei ...

Basidia
A basidium () is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium. Tertiary mycelium is highly-coiled secondary myceliuma dikaryon. The presence of basidia is one of the main characteristic features of the Basidiomycota. A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (), and is forcibly discharged upon maturity. The word ''basidium'' literally means "little pedestal", from the way in which the basidium supports the spores. However, some biologists suggest that the structure more closely resembles a club. An immature basidium is known as a basidiole. Structure Most basidiomycota have single celled basidia (holobasidia), but in some groups basidia can be multice ...

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basidiospore
A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the ...
