Cortinarius Orellanus
''Cortinarius orellanus'', commonly known as the fool's webcap or fools webcap, is a species of deadly fungus in the family Cortinariaceae native to Europe. Within the genus it belongs to a group known as the Orellani, all of which are highly toxic—eating them results in kidney failure, which is often irreversible. The mushroom is generally tan to brown all over. Taxonomy ''Cortinarius orellanus'' was first described by Swedish mycologist Elias Magnus Fries in his 1838 book ''Epicrisis Systematis Mycologici seu Synopsis Hymenomycetum''. It is one of seven highly toxic species that make up the orellani, a subgenus within genus ''Cortinarius''. Description ''Cortinarius orellanus'' has a concave cap of diameter, though rare specimens reach across. The cap flattens with age. In colour, it is an orange-brown, and is covered in fine, fibrous scales but become smooth with age. The cap surface turns black with potassium hydroxide. The thick gills are light ochre-coloured, changing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botanica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trama (mycology)
In mycology, the term trama is used in two ways. In the broad sense, it is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body. It is distinct from the outer layer of tissue, known as the pileipellis or cuticle, and from the spore-bearing tissue layer known as the hymenium. In essence, the trama is the tissue that is commonly referred to as the "flesh" of mushrooms and similar fungi.Largent D, Johnson D, Watling R. 1977. ''How to Identify Mushrooms to Genus III: Microscopic Features''. Arcata, CA: Mad River Press. . pp. 60–70. The second use is more specific, and refers to the "hymenophoral trama" that supports the hymenium. It is similarly interior, connective tissue, but it is more specifically the central layer of hyphae running from the underside of the mushroom cap to the lamella or gill, upon which the hymenium rests. Various types have been classified by their structure, including trametoid, cantharelloid, boletoid, and agaricoid, with agaricoid the ...

Cortinarius
''Cortinarius'' is a globally distributed genus of mushrooms in the family Cortinariaceae. It is suspected to be the largest genus of agarics, containing over 2,000 widespread species. A common feature among all species in the genus ''Cortinarius'' is that young specimens have a cortina (veil) between the cap and the stem, hence the name, meaning ''curtained''. Most of the fibres of the cortina are ephemeral and will leave no trace once gone, except for limited remnants on the stem or cap edge in some species. All have a rusty brown spore print. The common names cortinar and webcap refer to members of the genus. Due to dangerous toxicity of several species (such as ''Cortinarius orellanus'') and the fact that it is difficult to distinguish between various species of the genus, non-expert consumption of mushrooms from the genus is discouraged. Distinguishing features The veil protects the gills in younger specimens and usually disappears leaving little to no trace of itself as the ...

Fungi Of Europe
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] |
List Of Deadly Fungus Species
Although many people have a fear of mushroom poisoning by "toadstools", only a small number of the many macroscopic fruiting bodies commonly known as mushrooms and toadstools have proven fatal to humans. This list is not exhaustive and does not contain many fungi that, although not deadly, are still harmful.

Orellanine
Orellanine or orellanin is a mycotoxin found in a group of mushrooms known as the Orellani of the family Cortinariaceae. Structurally, it is a bipyridine N-oxide compound somewhat related to the herbicide diquat. History Orellanine first came to people's attention in 1952 when a mass poisoning of 102 people in Konin, Poland, resulted in 11 deaths. Orellanine comes from a class of mushrooms that fall under the genus ''Cortinarius,'' and has been found in the species '' C. orellanus'', '' rubellus'', ''henrici'', '' rainerensis'' and '' bruneofulvus''. Poisonings related to these mushrooms have occurred predominately in Europe where mushroom foraging was common, though cases of orellanine poisoning have been reported in North America and Australia as well. There are several reported cases of people ingesting orellanine-containing mushrooms after mistaking them for edible or hallucinogenic mushrooms. Orellanine was first isolated in 1962, when Stanisław Grzymala extracted and iso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chanterelle
Chanterelle is the common name of several species of fungi in the genera '' Cantharellus'', '' Craterellus'', '' Gomphus'', and ''Polyozellus''. They are among the most popular of wild edible mushrooms. They are orange, yellow or white, meaty and funnel-shaped. On the lower surface, underneath the smooth cap, most species have rounded, forked folds that run almost all the way down the stipe, which tapers down seamlessly from the cap. Many species emit a fruity aroma, reminiscent of apricots, and often have a mildly peppery taste (hence its German name, '' Pfifferling''). The name chanterelle originates from the Greek '' kantharos'' meaning "tankard" or "cup", a reference to their general shape. Description At one time, all yellow or golden chanterelles in western North America had been classified as '' Cantharellus cibarius''. Using DNA analysis, they have since been shown to be a group of related species. In 1997, the Pacific golden chanterelle ('' C. formosus'') and ''C. ci ...

Nephrotoxicity
Nephrotoxicity is toxicity in the kidneys. It is a poisonous effect of some substances, both toxic chemicals and medications, on kidney function. There are various forms, and some drugs may affect kidney function in more than one way. Nephrotoxins are substances displaying nephrotoxicity. Nephrotoxicity should not be confused with some medications predominantly excreted by the kidneys needing their dose adjusted for the decreased kidney function (e.g., heparin, lithium). Types of toxicity Cardiovascular * General: diuretics, β-blockers, vasodilator agents * Local: ACE inhibitors, ciclosporin, tacrolimus. Direct tubular effect * Proximal convoluted tubule: Aminoglycoside antibiotics (e.g., gentamicin), amphotericin B, cisplatin, radiocontrast media, immunoglobulins, mannitol * Distal tubule: NSAIDs (e.g. aspirin, ibuprofen, diclofenac), ACE inhibitors, ciclosporin, lithium salts, cyclophosphamide, amphotericin B * Tubular obstruction: sulphonamides, methotrexate, acicl ...

Stipe (mycology)
In mycology, a stipe () is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe some distance. Fungi that have stipes are said to be stipitate. The evolutionary benefit of a stipe is generally considered to be in mediating spore dispersal. An elevated mushroom will more easily release its spores into wind currents or onto passing animals. Nevertheless, many mushrooms do not have stipes, including cup fungi, puffballs, earthstars, some polypores, jelly fungi, ergots, and smuts. It is often the case that features of the stipe are required to make a positive identification of a mushroom. Such distinguishing characters include: # the texture of the stipe (fibrous, brittle, chalky, leathery, firm, etc.) # whether it has remains of a partial veil (such as an annulus or cortina) or universal ve ...

Lucien Quélet
Lucien Quélet in 1869 Lucien Quélet (14 July 1832 – 25 August 1899) was a French naturalist and mycologist. Quélet discovered several species of fungi and was the founder of the Société mycologique de France, a society devoted to mycological studies. Quélet, having been born in Montécheroux, Doubs, to a farmer, was soon orphaned, and spent his childhood with and was raised by his aunts. In his youth, he is known to have shown a great interest in mycology and botany in general, but also other subject areas such as ornithology and malacology, the study of mollusks. He was schooled at the Montbéliard college, and later studied medicine in Strasbourg. In 1884, he founded the mycological society known as the Société mycologique de France, of which he became the first president. Several years after this, in 1888, Quélet wrote a book, ''Flore mycologique de la France et des pays limitrophes'' (''Mycological flora of France and neighbouring countries''). Quélet also des ...
