Gyromitra
''Gyromitra'' () is a genus of about 18 species of ascomycete fungi. They are a false morel - a frequently toxic mushroom that can be mistaken for edible mushrooms of the genus ''Morchella'' (morels). Taxonomy The name ''Gyromitra'' comes from ''gyro'' meaning ''convoluted'' and ''mitra'' meaning ''turban''. Analysis of the ribosomal DNA of many of the Pezizales showed the genus ''Gyromitra'' to be most closely related to the genus '' Discina'', and also '' Pseudorhizina'', '' Hydnotrya'', and only distantly related to ''Helvella''. Thus the four genera are now included in the family Discinaceae. Species The genus consists of the following species: * ''Gyromitra ambigua'' * '' Gyromitra anthracobia'' * ''Gyromitra brunnea'' - known as a false morel * ''Gyromitra bubakii'' * ''Gyromitra californica'' * ''Gyromitra caroliniana'' (North America) * ''Gyromitra esculenta'' (Pers.)

Gyromitra Esculenta
''Gyromitra esculenta'' is an ascomycete fungus from the genus '' Gyromitra'', widely distributed across Europe and North America. It normally fruits in sandy soils under coniferous trees in spring and early summer. The fruiting body, or mushroom, is an irregular brain-shaped cap dark brown in colour that can reach high and wide, perched on a stout white stipe up to high. Although potentially fatal if eaten raw, ''Gyromitra esculenta'' is a popular delicacy in Scandinavia, Eastern Europe, and the upper Great Lakes region of North America. Although popular in some districts of the eastern Pyrenees, it is prohibited from sale to the public in Spain. It may be sold fresh in Finland, but it must be accompanied by warnings and instructions on correct preparation. Although it is still commonly parboiled before preparation, evidence suggests that even this procedure may not make ''Gyromitra esculenta'' entirely safe for consumption. When consumed, the principal active agent, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyromitra Caroliniana
''Gyromitra caroliniana'', known commonly as the Carolina false morel or big red, is an ascomycete fungus of the genus ''Gyromitra'', within the Pezizales group of fungi. It is found in hardwood forests of the southeastern United States, where it fruits in early spring soon after snowmelt. The fruit body, or ascocarp, appears on the ground in woodland, and can grow to massive sizes. The heavily wrinkled cap is red-brown in color, nearly spherical to roughly elliptical in shape, and typically measures tall and wide. The stipe is massive, up to thick, with a white felt-like surface. The brittle flesh is densely packed into the cap in convoluted folds that form internal locules. Taxonomy The species was originally named ''Morchella caroliniana'' by French botanist Louis Augustin Guillaume Bosc in 1811, and later sanctioned under this name by Elias Fries in 1822. It was transferred to ''Gyromitra'' by Fries in 1871. ''Gyromitra caroliniana'' is the type species of subgenus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyromitrin
Gyromitrin is a toxin and carcinogen present in several members of the fungal genus '' Gyromitra'', like '' G. esculenta''. Its formula is . It is unstable and is easily hydrolyzed to the toxic compound monomethylhydrazine . Monomethylhydrazine acts on the central nervous system and interferes with the normal use and function of vitamin B6. Poisoning results in nausea, stomach cramps, and diarrhea, while severe poisoning can result in convulsions, jaundice, or even coma or death. Exposure to monomethylhydrazine has been shown to be carcinogenic in small mammals. History Poisonings related to consumption of the false morel ''Gyromitra esculenta'', a highly regarded fungus eaten mainly in Finland and by some in parts of Europe and North America, had been reported for at least a hundred years. Experts speculated the reaction was more of an allergic one specific to the consumer, or a misidentification, rather than innate toxicity of the fungus, due to the wide range in effects ...

Gyromitra Infula
''Gyromitra infula'', commonly known as the hooded false morel or the elfin saddle, is a fungus in the family Helvellaceae. The dark reddish-brown caps of the fruit bodies develop a characteristic saddle-shape in maturity, and the ends of both saddle lobes are drawn out to sharp tips that project above the level of the fruit body. The stipe is white or flushed pale brown, smooth on the outside, but hollow with some chambers inside. It is found in the Northern Hemisphere, usually in the late summer and autumn, growing on rotting wood or on hard packed ground. ''G. infula'' is considered inedible as it contains the toxic compound gyromitrin which, when metabolized by the body, is converted into monomethylhydrazine, a component of some rocket fuels. The toxin may be removed by thorough cooking. ''Gyromitra'' fungi are included in the informal category "false morels". Taxonomy The fungus was first described in 1774 by German mycologist Jacob Christian Schäffer as ''H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gyromitra Gigas
''Gyromitra gigas'', commonly known as the giants false morel, snow morel, snow false morel, calf brain, or bull nose, is a fungus and a member of the Ascomycota. ''G. gigas'' is found in Europe. It is referred to as one of the false morels, due to its similar appearance and occurrence in the spring and early summer in similar habitats to true morels ('' Morchella'' ssp.). It contains small quantities of hydrazines, its content in gyromitrin was scientifically assess by Viernstein et al. otanical identification 1980and resulted of about 1mg per kg of fresh mushroom (roughly 1500 fold less compared to esculenta). No casualties have been ascribed to its consumption, parboiling is still highly recommended. Some guides have listed it as being edible if properly prepared. However, consumption is not recommended due to variability and similarity to other more toxic species of ''Gyromitra''. This fungus has been banned for sale in France since 1991 due to potential toxicity, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
