Amanita Gemmata
''Amanita gemmata'', commonly known as the gemmed amanita or the jonquil amanita, is an agaric mushroom of the family Amanitaceae and genus ''Amanita''. The fruit body has a cap that is a dull to golden shade of yellow, and typically in diameter. The cap surface is sticky when moist, and characterized by white warts, which are easily detached. It is initially convex, and flattens out when mature. The flesh is white and does not change colour when cut. The gills are white and closely spaced. The stem is pale yellow, and measures long by thick. The partial veil that covers the young fruit body turns into the ring on the stem at maturity. The spore print is white. It resembles numerous other species. This species is a mycorrhizal fungus, widespread in Europe. It can grow either singly, scattered, or in groups. It prefers habitats like coniferousand mixed forests and alongside paths, where it fruits in summer and fall. It is a toxic mushroom, containing ibotenic acid and muscimol. ...

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. He is sometimes called the Mycology, "Linnaeus of Mycology". In his works he described and assigned botanical names to hundreds of fungus and lichen species, many of which remain authoritative today. 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 studied under Carl Adolph Agardh and Anders Jahan Retzius. He obtained his doctorate in 1814. In the same year he was appointed an associate professorship in botany. Fries edited several exsiccata series, the first starting in 1818 under the title ''Lichenes Sveciae exsiccati, curante Elia Fries'' and the last together with Franz Joseph Lagger under the title ''Hieracia europaea exsiccata''. He was elected a member of the Royal Swedish Academ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annulus (mycology)
An annulus is the ring-like or collar-like structure sometimes found on the Stipe (mycology), stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gill (mushroom), gills or other spore-producing surface. It can also be called a ring which is what the Latin word annulus directly translates as. The modern usage of the Latin word originates from the early days of botany and mycology when species Species description, descriptions were only written in Latin. Outside of the formal setting of scientific publications which still have a Latin requirement, it will often just be referred to as a ring or stem ring in field guides and on identification websites. Ring descriptions The way in which the structure and appearance of rings is described can vary with author and the description may only note the existence of a ring without providing specific information in cases where the ring lacks any notable features that ...

Amanita Jacksonii
''Amanita jacksonii'', also known as Jackson's slender amanita, American Slender Caesar, and Eastern Caesar's Amanita, is a North American species of fungus in the family Amanitaceae. It is a reddish-orange colored mushroom species which can be identified by its yellow gills, large, white, sacklike volva. Taxonomy It was given its current name in 1984 by Canadian mycologist René Pomerleau. Description The cap of the mushroom is wide; oval at first, becoming convex, typically with a central bump; sticky; brilliant red or orange, fading to yellow on the margin; typically without warts or patches; the margin lined for about 40–50% of the cap's radius. The red pigment fades from margin toward the center with age. Gills are moderately crowded to crowded, orange-yellow to yellow-orange to yellow. They are free from the stem or slightly attached to it; yellow to orange-yellow; crowded; not bruising. The short gills are subtruncate to truncate. Its stipe measures , is yellow ...

Amanita Vaginata
''Amanita vaginata'', commonly known as the grisette or the grisette amanita, is an edible mushroom in the fungus family Amanitaceae. The cap is gray or brownish, in diameter, and has furrows around the edge that duplicate the gill pattern underneath. Unlike many other ''Amanita'' mushrooms, ''A. vaginata'' lacks a ring on the stem. ''A. vaginata'' is widely distributed in Europe and North America. It is not recommended for consumption due to the possibility of confusing it with related poisonous species. Description The cap is in diameter and gray to grayish-brown in color; initially the cap is oval, then as it matures it becomes progressively conical, convex, and eventually flattened, sometimes with a small umbo (a rounded elevation in the center of the cap). The gills are white, free (not attached to the stem) to narrowly attached, moderately crowded together, and sometimes have a grayish tint; the lamellulae (small gills that run from the edge of the cap towards t ...

Amanita Fulva
''Amanita fulva'', commonly called the tawny grisette or the orange-brown ringless amanita, is a basidiomycete mushroom of the genus ''Amanita''. It is found frequently in deciduous and coniferous forests of Europe, and possibly North America. Taxonomy ''Amanita fulva'' was first described by Jacob Christian Schäffer in 1774. Historically, both the tawny grisette and the grisette ('' A. vaginata'') were placed in the genus '' Amanitopsis'' due to their lack of a ring, unlike other ''Amanita'' species. However this distinction is now seen as insufficient to warrant a separate genus. Today, ''A. fulva'' and similar ringless species of ''Amanita'' are placed in the section '' Vaginatae'' ss according to the classification of Bas. Description The cap is orange-brown, paler towards the margin, and darker (even very dark brown) in the center, up to in diameter. It develops an umbo when expanded, and has a strongly striated margin. Its surface is smooth, slightly sticky ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amanita Ceciliae
''Amanita ceciliae'', commonly called snakeskin grisette, strangulated amanita, and the Cecilia's ringless amanita, is a basidiomycete fungus in the genus ''Amanita''. First described in 1854 by Miles Joseph Berkeley and Christopher Edmund Broome, it was given its current name by Cornelis Bas in 1984. It is characterized by bearing a large fruit body with a brown cap across. The cap has charcoal-grey patches, which are easily removable. The stipe is long, white in colour, and there is no ring on it. It is slightly tapered to the top and has irregular cottony bands girdling the base. The universal veil is grey. Spores are white, spherical in shape, non-amyloid, and measure 10.2–11.7 micrometres. The mushrooms are considered edible, but field guides typically advise caution in selecting them for consumption, due to risks of confusion with similar toxic species. ''A. ceciliae'' is found in woods throughout Europe and North America, where it fruits during summer and au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amanita Farinosa
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 (and many species of unknown edibility). The genus is responsible for approximately 95% of 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 . 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, '' A. basii'' and similar species in Mexico, '' A. caesarea'' and the "Blusher" '' A. rubescens'' in Europe, and '' A. chepangiana'' in Southeast Asia.

Amanita Muscaria
''Amanita muscaria'', commonly known as the fly agaric or fly amanita, is a basidiomycete fungus of the genus ''Amanita''. It is a large white-lamella (mycology), gilled, white-spotted mushroom typically featuring a bright red cap covered with distinctive white warts. It is one of the most recognizable fungi in the world. ''A.muscaria'' exhibits complex genetic diversity that suggests it is a species complex rather than a single species. It is a widely distributed mushroom native to temperate and boreal forests of the Northern Hemisphere, now also naturalized in the Southern Hemisphere, forming symbiotic relationships with various trees and spreading invasively in some regions. Its name derives from its traditional use as an insecticide. It can cause poisoning, especially in children and those seeking its hallucinogenic effects, due to psychoactive compounds like muscimol and the ibotenic acid; however, fatal poisonings are extremely rare. Boiling it reduces toxicity by removi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muscimol
Muscimol, also known as agarin or pantherine, as well as 5-(aminomethyl)-1,2-oxazol-3-ol, is the principal psychoactive constituent of ''Amanita muscaria'' and '' Amanita pantherina''. Muscimol is an isoxazole alkaloid and a potent and selective orthosteric agonist for the GABAA receptor It displays sedative-hypnotic, depressant and hallucinogenic psychoactivity. It is widely used to study GABAergic function in the brain. Muscimol is under investigation for its potential to treat anxiety, insomnia, and neurological disorders, though its psychoactive nature requires careful regulation. A systematic review and meta-analysis of 22 studies found that muscimol reduces neuropathic pain symptoms, with effects beginning within 15 minutes and lasting up to three hours. Muscimol was tested in small clinical trials between 1977 and 1982 for conditions like schizophrenia, Huntington’s disease, and tardive dyskinesia, but showed limited efficacy and was eventually supplanted by the re ...

Ibotenic Acid
Ibotenic acid or (''S'')-2-amino-2-(3-hydroxyisoxazol-5-yl)acetic acid, also referred to as ibotenate, is a naturally occurring alpha-amino acid found in certain ''Amanita'' mushrooms, that primarily acts as a potent glutamate receptor agonist that precipitates neurological effects and is used experimentally as a brain-lesioning agent in mice and rats. Ibotenic acid is a conformationally-restricted analogue of glutamate that acts as a non-selective glutamate receptor agonist, strongly activating NMDA, group I and II metabotropic glutamate receptors, and weakly activating AMPA and kainate receptors. It is a prodrug of muscimol, broken down by the liver into this more stable compound, which acts as a potent GABAA and GABAA-ρ receptor agonist. Although its psychoactive effects are not well understood, some researchers speculate that ibotenic acid itself may have stimulant properties. Ibotenic acid is biosynthesized from glutamic acid by hydroxylation catalyzed by an F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixed Forest
Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions. These forests are richest and most distinctive in central China and eastern North America, with some other globally distinctive ecoregions in the Himalayas, Western and Central Europe, the southern coast of the Black Sea, Australasia, Southwestern South America and the Russian Far East. Ecology The typical structure of these forests includes four layers. * The uppermost layer is the canopy composed of tall mature trees ranging from high. Below the canopy is the three-layered, shade-tolerant understory that is roughly shorter than the canopy. * The top layer of the understory is the sub-canopy composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. * Below the sub-canopy is ...
