Agaricus Cupreobrunneus
''Agaricus cupreobrunneus'', commonly known as the brown field mushroom, is an edible mushroom of the genus ''Agaricus''. Description The brown cap is wide with flattened reddish-brown fibrils. The white stalk is tall and 1–2 cm wide. The spores are dark brown, elliptical, and smooth. Distribution and habitat ''Agaricus cupreobrunneus'' tends to fruit in disturbed areas and grassy places, such as lawns, pastures, and roadsides. It can fruit by itself, gregariously, or in fairy rings. Edibility ''Agaricus cupreobrunneus'' is edible and good. Its taste is comparable to that of ''Agaricus campestris'', but it is comparatively lacking in texture. ''A. cupreobrunneus'' is not currently cultivated on a widespread basis, but is commonly eaten by collectors in the areas in which it grows. It does not contain the carcinogen agaritine, which appears in many other members of the genus ''Agaricus''. Similar species ''Agaricus cupreobrunneus'' is similar in general appearance ...

Agaricus Argenteus
''Agaricus'' is a genus of mushrooms containing both edible and poisonous species, with over 400 members worldwide and possibly again as many disputed or newly-discovered species. The genus includes the common ("button") mushroom (''Agaricus bisporus'') and the field mushroom ('' A. campestris''), the dominant cultivated mushrooms of the West. Members of ''Agaricus'' are characterized by having a fleshy cap or pileus, from the underside of which grow a number of radiating plates or gills, on which are produced the naked spores. They are distinguished from other members of their family, Agaricaceae, by their chocolate-brown spores. Members of ''Agaricus'' also have a stem or stipe, which elevates it above the object on which the mushroom grows, or substrate, and a partial veil, which protects the developing gills and later forms a ring or annulus on the stalk. The genus contains the most widely consumed and best-known mushroom today, '' A. bisporus'', with '' A. arvensis'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poisonous Mushroom
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 ...

Agaricus Hondensis
''Agaricus hondensis'', commonly known as the felt-ringed agaricus, is a species of fungus in the family Agaricaceae. The species was officially described in 1912 by mycologist William Alphonso Murrill, along with three other ''Agaricus'' species that have since been placed in synonymy with ''A. hondensis''. Found in the Pacific Northwest region of North America, ''A. hondensis'' fruits in the fall under conifers or in mixed forests. The fungus produces fruit bodies (mushrooms) with white to gray-brown caps up to in diameter covered with pale pinkish-brown scales that darken in age. The tightly-packed gills on the cap underside are initially white before becoming pinkish, lilac-gray, and finally brownish as the spores mature. The stout stipe is bulbous and has a thick, white, felt-like ring. The mushroom is poisonous, and causes severe gastrointestinal upset if consumed. It has an unpleasant odor similar to phenol or creosote, and develops a soapy-metallic taste w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agaricus Augustus
''Agaricus augustus'', known commonly as the prince, is a basidiomycete fungus of the genus ''Agaricus''. Taxonomy According to Heinemann's (1978) popular division of ''Agaricus'', ''A. augustus'' belongs to section ''Arvenses''. The system proposed by Wasser (2002) classifies ''A. augustus'' within subgenus ''Flavoagaricus'', section ''Majores'', subsection ''Flavescentes''. Moreover, there have been attempts to recognise distinct varieties, namely ''A. augustus'' var. ''augustus'' Fr., and ''A. augustus'' var. ''perrarus'' (Schulzer) Bon & Cappelli. The specific epithet ''augustus'' is a Latin adjective meaning noble. Description The fruiting bodies of ''Agaricus augustus'' are large and distinctive agarics. The cap shape is hemispherical during the so-called button stage, and then expands, becoming convex and finally flat, with a diameter from . The cap cuticle is dry, and densely covered with concentrically arranged, brown-coloured scales on a white to yellow background. ...

Agaritine
Agaritine is an aromatic hydrazine-derivative mycotoxin in mushroom species of the genus ''Agaricus''. It is an α-aminoacid and a derivative of phenylhydrazine. Occurrence Agaritine is present as a natural phytochemical in fresh samples of at least 24 species of the genera ''Agaricus'', '' Leucoagaricus'', and ''Macrolepiota''. Mushrooms of these species are found around the world. These mushrooms grow in a wide range of habitats; indeed, one species alone, '' Agaricus bisporus'', is cultivated in over 70 countries and on every continent except Antarctica. ''A. bisporus'', also known as the common button mushroom, is of particular socio-economic importance in developed countries. Agaritine content varies between individual mushrooms and across species. Agaritine content (% fresh weight) in raw ''Agaricus bisporus'', for example, ranges from 0.033% to 0.173%, with an average of 0.088%. The highest amount of agaritine is found in the cap and gills of the fruiting body, and the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julius Schäffer
Julius Schäffer (3 June 1882 – 21 October 1944) was a German mycologist. His contributions include studies on the Agaricales (gilled mushrooms), especially the genus ''Russula'', about which he wrote a monograph in 1933. Later, he revised the genus in the series ''Die Pilze Mitteleuropas'' (1926–1967); his notes were published posthumously by his wife Liesel in 1952 with the help of other mycologists. The work was considered the "authoritative treatment of the group for Central Europe". One of the ''Russula'' species that was first described in this publication was '' R. laeta''. Schäffer developed a chemical test to help with the identification of ''Agaricus'' species. A positive reaction of Schaeffer's test, which uses the reaction of aniline and nitric acid on the surface of the mushroom, is indicated by an orange to red color; it is characteristic of species in the section ''Flavescentes''. The compounds responsible for the reaction were named schaefferal A and B to honor Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agaricus Campestris
''Agaricus campestris'' is a widely eaten gilled mushroom closely related to the cultivated button mushroom ''Agaricus bisporus''. It is commonly known as the field mushroom or, in North America, meadow mushroom. Taxonomy This species was originally noted and named in 1753 by Carl Linnaeus as ''Agaricus campestris''. It was placed in the genus ''Psalliota'' by Lucien Quelet in 1872. Some variants have been isolated over the years, a few of which now have species status, for example, ''Agaricus bernardii'' Quel. (1878), ''Agaricus bisporus'' (J.E. Lange) Imbach (1946), '' Agaricus bitorquis'' (Quel.) Sacc. (1887), ''Agaricus cappellianus'' Hlavacek (1987), and ''Agaricus silvicola'' (Vittad.) Peck (1872). Some were so similar they did not warrant even varietal status, while others have retained it. ''Agaricus campestris'' var. ''equestris'' (F.H.Moller) Pilat (1951) is still valid. ''A. campestris'' var. ''isabellinus'' (F.H.Moller) Pilat (1951), and ''A. campestris'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairy Ring
A fairy ring, also known as fairy circle, elf circle, elf ring or pixie ring, is a naturally occurring ring or arc of mushrooms. They are found mainly in forested areas, but also appear in grasslands or rangelands. Fairy rings are detectable by sporocarps (fungal spore pods) in rings or arcs, as well as by a necrotic zone (dead grass), or a ring of dark green grass. Fungus mycelium is present in the ring or arc underneath. The rings may grow to over in diameter, and they become stable over time as the fungus grows and seeks food underground. Fairy rings are the subject of much folklore and myth worldwide—particularly in Western Europe. They are often seen as hazardous or dangerous places, and linked with witches or the Devil in folklore. Conversely, they can sometimes be linked with good fortune. Genesis The mycelium of a fungus growing in the ground absorbs nutrients by secretion of enzymes from the tips of the hyphae (threads making up the mycelium). This breaks down larg ...
