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 ...

Cortinarius Violaceus
''Cortinarius violaceus'', commonly known as the violet webcap or violet cort, is a fungus in the webcap genus ''Cortinarius'' native across the Northern Hemisphere. The fruit bodies are dark purple mushrooms with caps up to across, sporting gills underneath. The stalk measures by , sometimes with a thicker base. The dark flesh has a smell reminiscent of cedar wood. Forming symbiotic (ectomycorrhizal) relationships with the roots of various plant species, ''C. violaceus'' is found predominantly in conifer forests in North America and deciduous forests in Europe. Though they are sometimes described as edible, the appearance of these mushrooms is more distinctive than their taste. The species was first described by Carl Linnaeus in 1753, and has undergone several name changes. It is the type species of the genus ''Cortinarius'', but is readily distinguished from other species in the genus by its dark colouration and distinct cystidia. There are some populations that seem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cortinarius Rubellus
''Cortinarius rubellus'', commonly known as the deadly webcap, is a species of fungus in the family Cortinariaceae, native to high-latitude temperate to subalpine forests of Eurasia and North America. 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, with a conical to convex cap in diameter, adnate gills and a tall stipe. Taxonomy British naturalist Mordecai Cubitt Cooke described ''Cortinarius rubellus'' in 1887 from material collected by a Dr. Carlyle at Orton Moss near Carlisle, Cumbria. The name was rarely used before 1980, however. ''Cortinarius orellanoides'' was described by Henry in 1937 from mushrooms growing under bracken (''Pteridium aquilinum'') and beech in France, while Robert Kühner and Henri Romagnesi described ''C. speciosissimus'' (initially ''C. speciosus'', but that name had already been given to ano ...

Cortinarius Archeri
''Cortinarius archeri'' is a species of mushroom in the genus ''Cortinarius'' native to Australia. The distinctive mushrooms have bright purple caps that glisten with slime, and appear in autumn in eucalypt forests. Taxonomy English clergyman Miles Joseph Berkeley described ''Cortinarius archeri'' in 1860 from a specimen collected in Cheshunt, Tasmania in April 1856. The species name honours the collector—naturalist William Archer, who was the secretary of the Royal Society of Tasmania. In 1891, the German botanist Otto Kuntze published ''Revisio generum plantarum'', his response to what he perceived as poor method in existing nomenclatural practice. He called the species ''Gomphos archeri'', citing the genus ''Gomphos'' as described by Giovanni Antonio Battarra in 1755 taking precedence over ''Cortinarius''. However, Kuntze's revisionary programme was not accepted by the majority of botanists. Within the genus, ''Cortinarius archeri'' belongs to the subgenus ''Myxacium'', w ...

Cortinarius Caperatus
''Cortinarius caperatus'' is an edible mushroom of the genus ''Cortinarius'' found in northern regions of Europe and North America. It was known as ''Rozites caperata'' for many years before genetic studies revealed that it belonged to the genus ''Cortinarius''. The fruit bodies appear in autumn in coniferous and beech woods as well as heathlands in late summer and autumn. The ochre-coloured cap is up to 10 cm (4 in) across and has a fibrous surface. The clay-colored gills are attached to the stipe under the cap, and the stipe is whitish with a whitish ring. The Latin specific name, ''caperatus'', means wrinkled, and refers to the distinctive texture of the cap. The flesh has a mild smell and flavor. Popular with mushroom foragers, ''C. caperatus'' is picked seasonally in throughout Europe. Although mild-tasting and highly regarded, the mushrooms are often infested with maggots. In central Europe, old specimens could be confused with the poisonous '' Inosperm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cortinarius Sanguineus
''Cortinarius sanguineus'', commonly known as the blood red webcap, is a species of fungus in the genus ''Cortinarius''. Taxonomy Austrian naturalist Franz Xaver von Wulfen described the species as ''Agaricus sanguineus'' in 1781, reporting that it appeared in the fir tree forests around Klagenfurt and Ebenthal and in October. He noted that it was very pretty but edible. The specific epithet is the Latin word ''sanguineus'', meaning "bloody". Samuel Frederick Gray established ''Cortinarius'' as a genus in the first volume of his 1821 work ''A Natural Arrangement of British Plants'', recording the species as ''Cortinaria sanguinea'' "the bloody curtain-stool". Friedrich Otto Wünsche described it as ''Dermocybe sanguinea'' in 1877. Most mycologists retain ''Dermocybe'' as merely a subgenus of ''Cortinarius'' as genetically all the species lie within the latter genus. It is closely related to '' Cortinarius puniceus'', which grows under oak and beech from England and France. Des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cortinarius Praestans
''Cortinarius praestans'', also known as the goliath webcap, is a basidiomycete mushroom of the genus ''Cortinarius''. The mushroom has orangish-yellow caps that reach up to in diameter, and thick club-shaped stipes up to long. The edible mushroom is found in Europe. Taxonomy The species was first described as ''Agaricus praestans'' by the French botanist François Simon Cordier in 1870. It is commonly known as the "goliath webcap". Description left Mature caps are convex, usually grooved at the rolled-in margins, and typically reach diameters between . The surface color of the cap is chestnut or chocolate-brown with violet-copper tint. It has a light covering of surface fibrils and veil remnants that may appear as if pressed against the surface, or like small scales. The gills are whitish with an amethyst tint then later creamy clay- to rust-colored. They are crowded closely together, and have edges that are usually wavy and scalloped. The stem is long and thick, solid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Cortinariaceae
The Cortinariaceae are a large family of gilled mushrooms found worldwide, containing over 2100 species. The family takes its name from its largest genus, the varied species of the genus ''Cortinarius''. Many genera formerly in the Cortinariaceae have been placed in various other families, including Hymenogastraceae, Inocybaceae and Bolbitiaceae. The deadly toxin orellanine has been found in at least 34 Cortinariaceae. Taxonomic details Cortinariaceae is a family of mushrooms within the Order Agaricales. The spore producing hymenium is located on the gills. The pileipellis is a cutis. The spores are brown in deposit and, in most genera in this family, the spores are ornamented. Differences in genera ''Cortinarius'' are mushrooms with warted spores, which are rusty-brown in deposit. Mushrooms in this genus have a partial veil which is a cortina. These mushrooms are terrestrial and mycorrhizal, and can range from small to large and fleshy. Edibility Despite the vast number of sp ...

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] |
Cortinarius Austrovenetus
''Cortinarius austrovenetus'', alternately known as ''Dermocybe austroveneta'' and commonly known as the green skin-head but also known as green dermocybe is an inedible brightly coloured green gilled fungus that naturally occurs in south eastern Australia. Taxonomy Initially described as ''Cortinarius austrovenetus'' by Australian naturalist John Burton Cleland in 1928, this mushroom along with many other members of the group was separated from the huge genus ''Cortinarius'', and placed in the newer genus ''Dermocybe'', commonly called skin-heads, derived from the meaning of their scientific names. However, this genus is often treated as a subgenus of ''Cortinarius'' only. In 2007, Bruno Gasparini suggested that ''C. austrovenetus'' is the same species as another ''Cortinarius'' in subgenus ''Dermocybe'', '' C. walkerae''. If this is true, ''C. austrovenetus'' is a later synonym and the name C. walkerae would take precedence. Description The fruit bodies ...
