Coprinus Comatus
''Coprinus comatus'', commonly known as the shaggy ink cap, lawyer's wig, or shaggy mane, is a species of fungus. The young fruit bodies first appear as white cylinders emerging from the ground, then the bell-shaped caps open out. The white caps are covered with scales, the origin of its common names. The gills beneath the cap are white, then pink, then turn black. This mushroom is unusual because it will turn black and dissolve itself in a matter of hours after being picked or depositing spores. The mushroom is often seen growing about lawns, gravel roads, and waste areas in North America. When young it is an excellent edible mushroom but it spoils quickly and resembles some poisonous species. Taxonomy The shaggy ink cap was first described by Danish naturalist Otto Friedrich Müller in 1780 as ''Agaricus comatus'', before being given its current binomial name in 1797 by Christiaan Hendrik Persoon. Its specific name derives from ''coma'', or "hair", hence ''comatus'', "hair ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mushroom Poisoning
Mushroom poisoning is poisoning resulting from the ingestion of mushrooms that contain toxicity, toxic substances. Signs and symptoms, Symptoms can vary from slight Gastrointestinal tract, 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 Mycotoxin, toxic mushroom as an edible species. The most common reason for this misidentification is a close resemblance in terms of color and general Morphology (biology), 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. Some toxins, such as amatoxins, are Thermostability, thermostable and mushrooms containing such ...

Otto Friedrich Müller
Otto Friedrich Müller, also known as Otto Friedrich Mueller (2 November 1730 – 26 December 1784) was a Denmark, Danish natural history, naturalist and scientific illustrator. Biography Müller was born in Copenhagen. He was educated for the church, became tutor to a young nobleman, and after several years' travel with him, settled in Copenhagen in 1767, and married a lady of wealth. His first important works, ''Fauna Insectorum Friedrichsdaliana'' (Leipzig, 1764), and ''Flora Friedrichsdaliana'' (Strasbourg, 1767), giving accounts of the insects and flora of the estate of Frederiksdal House, Frederiksdal, near Copenhagen, recommended him to Frederick V of Denmark, by whom he was employed to continue the ''Flora Danica'' a comprehensive atlas of the flora of Denmark. Müller added two volumes to the three published by Georg Christian Oeder since 1761. The study of invertebrates began to occupy his attention almost exclusively, and in 1771 he produced a work in German on “Cer ...

Deliquescent
Hygroscopy is the phenomenon of attracting and holding water molecules via either absorption (chemistry), absorption or adsorption from the surrounding Natural environment, environment, which is usually at normal or room temperature. If water molecules become suspended among the substance's molecules, adsorbing substances can become physically changed, e.g. changing in volume, boiling point, viscosity or some other physical characteristic or property of the substance. For example, a finely dispersed hygroscopic powder, such as a salt, may become clumpy over time due to collection of moisture from the surrounding environment. ''Deliquescent'' materials are sufficiently hygroscopic that they dissolve in the water they absorb, forming an aqueous solution. Hygroscopy is essential for many plant and animal species' attainment of hydration, nutrition, reproduction and/or seed dispersal. Biological evolution created hygroscopic solutions for water harvesting, filament tensile strength, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panagrellus Redivivus
The free-living nematode ''Panagrellus redivivus'' (sour paste nematode, or beer mat nematode from its occurrence in constantly moist felt beer mats), is known to many aquarium enthusiasts and fish keepers as the microworm. It is a tiny roundworm used as the first food for larger kinds of newly-hatched fish, such as larval common carp. The microworm is widely used in aquaculture as food for a variety of fish and crustacean species. One of thirteen currently recognized species of ''Panagrellus'', ''P. redivivus'' is about 50 μm in diameter and just over 1 mm in length, barely visible to the naked eye. Subsisting on yeast, it is easily cultured at home on a substrate of flour paste or porridge inoculated with dry yeast. Females reach maturity in about three days and deliver live young rather than eggs, as most nematodes produce. The microworm has been used in genetic analysis studies, but not nearly as universally as its relative, ''Caenorhabditis elegans ''Caenorhabdi ...

Nematode
The nematodes ( or ; ; ), roundworms or eelworms constitute the phylum Nematoda. Species in the phylum inhabit a broad range of environments. Most species are free-living, feeding on microorganisms, but many are parasitic. Parasitic worms (helminths) are the cause of soil-transmitted helminthiases. They are classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa. Unlike the flatworms, nematodes have a tubular digestive system, with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species are uncertain. A 2013 survey of animal biodiversity suggested there are over 25,000. Estimates of the total number of extant species are su ...

Nematophagous Fungus
Nematophagous fungi are carnivorous fungi specialized in trapping and digesting nematodes. More than 700 species are known. Species exist that live inside the nematodes from the beginning and others that catch them, mostly with glue traps or in rings, some of which constrict on contact. Some species possess both types of traps. Another technique is to stun the nematodes using toxins, a method employed by '' Coprinus comatus'', '' Stropharia rugosoannulata'', and the family Pleurotaceae. The habit of feeding on nematodes has arisen many times among fungi, as is demonstrated by the fact that nematophagous species are found in all major fungal groups. Nematophagous fungi can be useful in controlling those nematodes that eat crops. '' Purpureocillium'', for example, can be used as a bio-nematicide. Types Fungi that feed on nematodes (as the most abundant and convenient prey species) mostly live in nitrogen-deficient habitats. These fungi can be divided into four main groups accord ...

Audubon
The National Audubon Society (Audubon; ) is an American non-profit environmental organization dedicated to conservation of birds and their habitats. Located in the United States and incorporated in 1905, Audubon is one of the oldest of such organizations in the world. There are completely independent Audubon Societies in the United States, which were founded several years earlier such as the Massachusetts Audubon Society, Indiana Audubon Society, and Connecticut Audubon Society. The societies are named for 19th century naturalist John James Audubon. The society has nearly 500 local chapters, each of which is an independent 501(c)(3) non-profit organization voluntarily affiliated with the National Audubon Society. They often organize birdwatching field trips and conservation-related activities. It also coordinates the Christmas Bird Count held each December in the U.S., a model of citizen science, in partnership with Cornell Lab of Ornithology, and the Great Backyard Bird Co ...

Podaxis Pistillaris
''Podaxis pistillaris'' is a xerophile, xerophilic Agaricaceae, agaric mushroom related to the puffballs and Coprinus, inkcaps. It is commonly known as the desert shaggy mane. It grows to 11 cm tall and thrives in deserts and semi-deserts of North America, Australia, and South Africa. Taxonomy Older synonyms for this species include ''Lycoperdon pistillare'' L. (1771) and ''Scleroderma pistillare'' (L.) Pers. (1801). The species' common name stems from its superficial resemblance to the shaggy mane, ''Coprinus comatus'', the deliquescing gills of which it lacks. Description The pod grows up to tall. It has a hard, woody Plant stem, stem. The large cap, which protects the blackish spore-bearing tissue, splits, and usually falls away at maturity, allowing the spores to be dispersed by wind. The spore print is dark brown to black. The spores are usually 10–14 (–16) by (8–) 9–12 μm broadly oval to sub-globose, smooth yellow to deep reddish-brown with a do ...

Coprine
Coprine is a mycotoxin. It was first isolated from common inkcap (''Coprinopsis atramentaria''). It occurs in mushrooms in the genera '' Coprinopsis''. When combined with alcohol, it causes "Coprinus syndrome". It inhibits the enzyme aldehyde dehydrogenase, which is involved in the metabolism of alcohol. This inhibition leads to a buildup of acetaldehyde, causing an alcohol flush reaction. Because of this, the mushroom is commonly referred to as Tippler's Bane. History Because of the similarities to disulfram (tetraethylthiuram disulfide) poisoning, it was long speculated that disulfram was the active ingredient in common inkcap. In 1956 it was reported that disulfram had been isolated from coprinus, but this finding could not be replicated. In 1975, coprine was identified as the compound in the common inkcap, with the mechanism identified in 1979. Symptoms Symptoms of coprine poisoning include facial reddening/flushing, nausea, vomiting, malaise, agitation, palpitations, tin ...

Coprinopsis Atramentaria
''Coprinopsis atramentaria'', commonly known as the common ink cap, tippler's bane, or inky cap, is a species of fungus. Previously known as ''Coprinus atramentarius'', it is the second best-known ink cap and previous member of the genus '' Coprinus'' after '' C. comatus''. The grey-brown cap is initially bell-shaped before opening, after which it flattens and disintegrates. The flesh is thin and the taste mild. It is a widespread and common throughout the Northern Hemisphere. Clumps of mushrooms arise after rain from spring to autumn, commonly in urban and disturbed habitats such as vacant lots and lawns, as well as grassy areas. It can be eaten, but due to the presence of coprine within the mushroom, it is poisonous when consumed with alcohol, as it heightens the body's sensitivity to ethanol in a similar manner to the anti-alcoholism drug disulfiram. Taxonomy The common ink cap was first described by French naturalist Pierre Bulliard in 1786 as ''Agaricus at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorophyllum Molybdites
''Chlorophyllum molybdites'', commonly known as the green-spored parasol, false parasol, green-spored lepiota and vomiter, is a common species of mushroom found in temperate and subtropical meadows and lawns. The species is poisonous and produces severe gastrointestinal symptoms of vomiting and diarrhea. It is the most commonly consumed poisonous mushroom in North America, often being misidentified as edible species like '' Chlorophyllum rhacodes'' (the shaggy parasol) and '' Macrolepiota procera'' (parasol mushroom). Description The pileus (cap) ranges from in diameter, hemispherical and with a flattened top. The cap is whitish in colour with coarse brownish scales. The gills are free and white, usually turning dark and green with maturity. It has a rare green spore print. The stipe ranges from tall and bears a double-edged ring. Its stem lacks the snakeskin pattern that is generally present on the parasol mushroom. The flesh is thick, and though firm at first, softens w ...
