Gyromitra Ambigua
''Paragyromitra ambigua'' is an ascomycete species of fungus in the family Discinaceae, and related to the false morel '' G. esculenta''. The species is found in North America, where it produces fruit bodies (mushrooms) that grow on the ground. The edibility of the fruit bodies is not known with certainty, and it is not recommended for consumption.

Sauvie Island
Sauvie Island is in the U.S. state of Oregon, originally named as Wapato Island or Wappatoo Island. It is the largest island along the Columbia River, at , and one of the largest river islands in the United States. It lies approximately northwest of downtown Portland, between the Columbia River to the east, the Multnomah Channel to the west, and the Willamette River to the south. A large portion of the island is designated as the Sauvie Island Wildlife Area. Sturgeon Lake, in the north central part of the island, is the most prominent water feature. The land area is , or . Most of the island is in Multnomah County, but the northern third is in Columbia County. The Wapato Bridge provides access across the Multnomah Channel from U.S. Route 30 and was completed in June 2008, replacing the first bridge to connect the island to the mainland which was opened on December 30, 1950. The island received the name "Sauvés Island" after Laurent Sauvé dit Laplante, a French-Canad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Ascocarp, fruiting body, or mushroom, is an irregular brain-shaped Pileus (mycology), cap, dark brown in colour, that can reach high and wide, perched on a stout white stipe (mycology), stipe up to high. Although potentially fatal if eaten raw (causing restrictions on its sales in some areas), ''G. esculenta'' is still commonly parboiled for consumption, being a popular delicacy in Europe and the upper Great Lakes region of North America; evidence suggests that thorough cooking does not eliminate all traces of mycotoxins. When consumed, the principal active mycotoxin, gyromitrin, is hydrolyzed into the toxic compound monomethylhydrazine, which hepatotoxicity, affects the liver, neurotoxicity, central nervous system, and sometimes the nephrotoxicity, kid ...

Fungi Described In 1881
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 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 group of related organisms, named the ''Eumycota'' (''true fungi'' or ''Eumycetes ...

Morchella
''Morchella'', the true morels, is a genus of edible sac fungi closely related to anatomically simpler cup fungi in the order Pezizales ( division Ascomycota). These distinctive fungi have a honeycomb appearance due to the network of ridges with pits composing their caps. Morels are prized by gourmet cooks, particularly in Catalan and French cuisine, but can be toxic if consumed raw or undercooked. Due to difficulties in cultivation, commercial harvesting of wild morels has become a multimillion-dollar industry in the temperate Northern Hemisphere, in particular North America, Turkey, China, the Himalayas, India, and Pakistan where these highly prized fungi are found in abundance. Typified by '' Morchella esculenta'' in 1794, the genus has been the source of considerable taxonomical controversy throughout the years, mostly with regard to the number of species involved, with some mycologists recognising as few as three species and others over thirty.

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 accumbens'' Harmaja (1986) * '' Gyromitra apiculatula'' (McKnight) Berthet (1972) * '' Gyromitra arctica'' Vassilkov (1969) * '' Gyromitra bubakii'' Velen. (1922) * '' Gyromitra californica'' (W. Phillips) Raitv. (1965) * '' Gyromitra chirripoensis'' L.D. Gómez (1972) * '' Gyromitra columbiana'' Harmaja (1986) * ...

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 s ...

Edible Mushroom
Edible mushrooms are the fleshy fruit bodies of numerous species of macrofungi (fungi that bear fruiting structures large enough to be seen with the naked eye). Edibility may be defined by criteria including the absence of poisonous effects on humans and desirable taste and aroma. Mushrooms that have a particularly desirable taste are described as "''choice''". Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor. To ensure safety, wild mushrooms must be correctly identified before their edibility can be assumed. Deadly poisonous mushrooms that are frequently confused with edible mushrooms include several species of the genus ''Amanita'', particularly '' A. phalloides'', the death cap. Some mushrooms that are edible for most people can cause allergic reactions in others; old or improperly stored specimens can go rancid and cause food poisoning. Additionally, mushrooms can absor ...

Basidiocarp
In fungi, a basidiocarp, basidiome, or basidioma () is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures. As with other sporocarps, epigeous (above-ground) basidiocarps that are visible to the naked eye (especially those with a more or less agaricoid morphology) are commonly referred to as mushrooms, while hypogeous (underground) basidiocarps are usually called false truffles. Structure All basidiocarps serve as the structure on which the hymenium is produced. Basidia are found on the surface of the hymenium, and the basidia ultimately produce spores. In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly and club fungi. In more complex basidiocarps, there is differentiation into a stipe, a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
False Morel
The name false morel is given to several species of mushroom which bear a resemblance to the highly regarded true morels of the genus ''Morchella''. Like ''Morchella'', false morels are members of the Pezizales, but within that group represent several unrelated taxa scattered through the families Morchellaceae, Discinaceae, and Helvellaceae, with the epithet "false morel" most often ascribed to members of the genus ''Gyromitra''. Compared to morels When gathering morels for mushrooms, care must be taken to distinguish them from potentially poisonous lookalikes. A great many morel lookalikes, and even morels themselves are toxic or cause gastrointestinal upset when consumed raw; furthermore, some of them such as ''Gyromitra esculenta'' remain toxic even after conventional cooking methods. Although some false morels can be eaten without ill effect, others can cause severe gastrointestinal upset, loss of muscular coordination (including cardiac muscle), or even death. Incidents o ...

Oregon
Oregon ( , ) is a U.S. state, state in the Pacific Northwest region of the United States. It is a part of the Western U.S., with the Columbia River delineating much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. The western boundary is formed by the Pacific Ocean. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early to mid-16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discinaceae
The Discinaceae are a family of ascomycete fungi, the best known members of which are the false morels of the genus ''Gyromitra''. Originally erected by Erich Heinz Benedix in 1961, it was found to be a discrete clade in a molecular study of ribosomal DNA by mycologist Kerry O'Donnell in 1997. As of 2008, the family is thought to contain 5 genera and 58 species. As of 2022, the GBIF accepts ''Discina'' (27 spp), '' Gymnohydnotrya'' (4 spp), ''Gyromitra'' (73 spp), '' Hydnotrya'' (52 spp) and '' Maublancomyces'' (1 sp). But calls ''Neogyromitra'' and '' Pseudorhizina'' doubtful. Members in the family Discinaceae are known to have epigeous and hypogeous species, and are characterized by ascomata composed of an inner layer of interwoven hyphae and an outer layer composed of elongated cells arranged perpendicular to its exterior. Discinaceae include species possessing saddle-shaped apothecia and hypogeous truffles. Discinaceae possess cylindrical, 8-spored, tapered asci and as ...
