Amanita Ibotengutake
''Amanita ibotengutake'' is a species of agaric fungus in the family Amanitaceae native to Japan. It was first described in 2002 as distinct on a genetic level from '' A. pantherina'', and earlier has been classified under that name. The scientific name derives from Japanese name of '' A. strobiliformis'', ''ibotengutake'' (疣天狗茸, lit. "wart tengu mushroom"), which inspired the name of ibotenic acid. ''A. ibotengutake'' contains ibotenic acid and muscimol, rendering it toxic Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a subst ... and psychoactive.

Agaric
An agaric () is a type of fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. In the UK, agarics are called "mushrooms" or "toadstools". In North America they are typically called "gilled mushrooms". "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body. Archaically, agaric meant 'tree-fungus' (after Latin ''agaricum''); however, that changed with the Linnaean interpretation in 1753 when Linnaeus used the generic name ''Agaricus'' for gilled mushrooms. Most species of agaricus belong to the order Agaricales in the subphylum Agaricomycotina. The exceptions, where agarics have evolved independently, feature largely in the orders Russulales, Boletales, Hymenochaetales, and several other groups of basidiomycetes. Old systems of classification placed all agarics in the Agaricales and some (mostly older) sources use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amanitaceae
The Amanitaceae is a family of mushroom-forming fungi. ''Amanita'' Pers. is one of the most specious and best-known fungal genera. The family, also commonly called the amanita family, is in order Agaricales, the gilled mushrooms. The family consists primarily of the large genus ''Amanita'', but also includes the smaller genera '' Amarrendia'', ''Catatrama'', ''Limacella'', ''Limacellopsis'', ''Saproamanita'', ''Torrendia'' and ''Zhuliangomyces''. Both '' Amarrendia'' and ''Torrendia'' are considered to be synonymous with ''Amanita'' but appear quite different because they are secotioid. The species are usually found in woodlands. The most characteristic emerge from an egg-like structure formed by the universal veil. This family contains several species valued for edibility and flavor, and other deadly poisonous ones. More than half the cases of mushroom poisoning stem from members of this family. The most toxic members of this group have names that warn of the poisonous nat ...

Amanita Pantherina
''Amanita pantherina'', also known as the panther cap, false blusher, and the panther amanita due to its similarity to the true blusher ('' Amanita rubescens''), is a species of fungus found in Europe and Western Asia. Description *Cap: 5–18 cm wide, hemispheric at first, then convex to plano-convex, deep brown to hazel-brown to pale ochraceous brown, densely distributed warts that are pure white to sordid cream, minutely verruculose, floccose, easily removable. Viscid when wet, with a short striate margin. The flesh is white, unchanging when injured. *Gills: adnexed to free, close to crowded, white becoming greyish, truncate. *Spores: white in deposit, smooth, broadly ellipsoid to ellipsoid to elongate, inamyloid, infrequently globose. 8–14 x 6–10 µm. *Stipe: 5–15 cm long × .6–3 cm wide, subcylindric, somewhat narrowing upward, white, becoming slightly tannish in age, stuffed then hollow, finely floccose becoming smooth above the ring, and wi ...

Amanita Strobiliformis
''Amanita strobiliformis'' is a species of mushroom. It is commonly referred to as warted amanita. Description The cap (mycology), cap is 3 to 10 inches across, is rough with warts which sometimes fall away leaving the cap smooth, whitish, and sometimes has some brown. The gill (mycology), gills are free and rounded behind. The veil is large and sometimes adhere to the margin of the cap. The stipe (mycology), stipe (stem) is 3 to 8 inches long, thick, white, bulbous, and sometimes weighs a pound. The spores are Ellipse, elliptical. Edibility Unknown The genus ''Amanita'' contains some of the most toxic fungi known. Some amanitas are deadly in only very small doses, while others are relatively harmless and sometimes even considered fit for human consumption. There are different views on ''A. strobiliformis'' edibility. Some sources advise against consuming them, other sources consider them edible.

Tengu
are a type of legendary creature found in Japanese folk religion (Shinto). They are considered a type of ''yōkai'' (supernatural beings) or Shinto ''kami'' (gods). The ''Tengu'' were originally thought to take the forms of birds of prey and a monkey deity, and they are traditionally depicted with human, monkey, and avian characteristics. Sarutahiko Ōkami is considered to be the original model of Konoha-Tengu (a supernatural creature with a red face and long nose), which today is widely considered the ''Tengu''s defining characteristic in the popular imagination. He is the Shinto monkey deity who is said to shed light on heaven and earth. Some experts theorize that Sarutahiko was a sun god worshiped in the Ise region prior to the popularization of Amaterasu. Buddhism long held that the ''Tengu'' were disruptive demons and harbingers of war. Their image gradually softened, however, into one of protective and even manifestations of Buddhist deities, if still dangerous, spirits ...

Ibotenic Acid
Ibotenic acid or (''S'')-2-amino-2-(3-hydroxyisoxazol-5-yl)acetic acid, also referred to as ibotenate, is a chemical compound and psychoactive drug which occurs naturally in ''Amanita muscaria'' and related species of mushrooms typically found in the temperate and boreal regions of the northern hemisphere. It is a prodrug of muscimol, broken down by the liver to that much stabler compound. It is a conformationally-restricted analogue of the neurotransmitter glutamate, and due to its structural similarity to this neurotransmitter, acts as a non-selective glutamate receptor agonist. Because of this, ibotenic acid can be a powerful neurotoxin in high doses, and is employed as a "brain-lesioning agent" through cranial injections in scientific research. The neurotoxic effects appear to be dose-related and risks are unclear through consumption of ibotenic-acid containing fungi, although thought to be negligible in small doses. Pharmacology Ibotenic acid acts as a potent agonist of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muscimol
Muscimol (also known as agarin or pantherine) is one of the principal psychoactive constituents of ''Amanita muscaria'' and related species of mushroom. Muscimol is a potent and selective orthosteric agonist for the GABAA receptors and displays sedative-hypnotic, depressant and hallucinogenic psychoactivity. This colorless or white solid is classified as an isoxazole. Muscimol went under clinical trial phase I for epilepsy, but the trial was discontinued. Biochemistry Muscimol is one of the psychoactive compounds responsible for the effects of ''Amanita muscaria'' intoxication. Ibotenic acid, a neurotoxic secondary metabolite of ''Amanita muscaria'', serves as a prodrug to muscimol when the mushroom is ingested or dried, converting to muscimol via decarboxylation. Muscimol is produced in the mushrooms ''Amanita muscaria'' (fly agaric) and ''Amanita pantherina'', along with muscarine (which is present in trace amounts and it is not active), muscazone, and ibotenic acid.

Mushroom Poisoning
Mushroom poisoning is poisoning resulting from the ingestion of mushrooms that contain toxic substances. Its symptoms can vary from slight gastrointestinal discomfort to death in about 10 days. Mushroom toxins are secondary metabolites produced by the fungus. Mushroom poisoning is usually the result of ingestion of wild mushrooms after misidentification of a toxic mushroom as an edible species. The most common reason for this misidentification is a close resemblance in terms of color and general morphology of the toxic mushrooms species with edible species. To prevent mushroom poisoning, mushroom gatherers familiarize themselves with the mushrooms they intend to collect, as well as with any similar-looking toxic species. The safety of eating wild mushrooms may depend on methods of preparation for cooking. Signs and symptoms Poisonous mushrooms contain a variety of different toxins that can differ markedly in toxicity. Symptoms of mushroom poisoning may vary from gastric upset t ...

Amanita
The genus ''Amanita'' contains about 600 species of agarics, including some of the most toxic known mushrooms found worldwide, as well as some well-regarded edible species. This genus is responsible for approximately 95% of the fatalities resulting from mushroom poisoning, with the death cap accounting for about 50% on its own. The most potent toxin present in these mushrooms is α-Amanitin. The genus also contains many edible mushrooms, but mycologists discourage mushroom hunters, other than experts, from selecting any of these for human consumption. Nonetheless, in some cultures, the larger local edible species of ''Amanita'' are mainstays of the markets in the local growing season. Samples of this are ''Amanita zambiana'' and other fleshy species in central Africa, ''Amanita basii, A. basii'' and similar species in Mexico, ''Amanita caesarea, A. caesarea'' and the "Blusher" ''Amanita rubescens'' in Europe, and ''Amanita chepangiana, A. chepangiana'' in South-East Asia.

Fungi Of Japan
A fungus ( : fungi 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 a 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 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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
