Phlegmacium Glaucopus
''Phlegmacium glaucopus'' is a species of fungus in the family Cortinariaceae. It is commonly known as the blue-foot webcap. Taxonomy The species was first described as ''Agaricus glaucopus'' by Jacob Christian Schäffer in 1774. It was reclassified as ''Cortinarius glaucopus'' in 1821 by the British mycologist Samuel Frederick Gray. However the fully taxonomic history of this species is complicated by numerous proposed variants and forms. Within the genus '' Cortinarius'', it was classified in the subgenus ''Phlegmacium'' and section ''Glaucopodes''. A 2014 genetic study confirmed it was synonymous with ''C. glaucopoides'' and that ''C. subrubrovelatus'' was a distinct species. In 2022 a genomic study was carried out which radically reshaped the family Cortinariaceae resulting in many ''Cortinarius'' species being transferred to new or existing genera. ''C. glaucopus, C. glaucopoides'' and ''C. glaucopoides'' were among the species transferred t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob Christian Schäffer
Jacob Christian Schäffer, alternatively Jakob, (31 May 1718 – 5 January 1790) was a German dean, professor, botanist, mycologist, entomologist, ornithologist and inventor. Biography From 1736 to 1738 he studied Theology at the University of Halle before becoming a teacher in Ratisbon. In 1760, the University of Wittenberg gave him the title of Doctor of Philosophy, and the University of Tübingen awarded him in 1763 the title of Doctor of Divinity. In 1741, he became a pastor of a Protestant parish. In 1779, while still a pastor, he also became the dean of the Protestant parish in Ratisbon. Works In 1759, Schäffer published ''Erleichterte Artzney-Kräuterwissenschaft'', a handbook of botany and the medicinal effects of plants for doctors and pharmacists. From 1762 to 1764, he wrote four richly illustrated volumes on mycology, ''Natürlich ausgemahlten Abbildungen baierischer und pfälzischer Schwämme, welche um Regensburg wachsen''. In 1774, he wrote ''Elementa Orni ... [...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 la ...

Fungi Of Europe
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tlaxcala City
Tlaxcala, officially Tlaxcala de Xicohténcatl (), is the capital city of the Mexican state of Tlaxcala and seat of the municipality of the same name. The city did not exist during the pre-Hispanic period but was laid out by the Spanish as a center of evangelization and governance after the Spanish conquest of the Aztec Empire. The city was designated as a diocese but eventually lost that status to Puebla as its population declined. The city still has many of its old colonial structures, including the former Franciscan monastery, and newer civic structures like the Xicohtencatl Theatre. History The name Tlaxcala most likely comes from a Nahuatl phrase which means “place of corn bread.” The Aztec glyph for the Mesoamerican dominion is two hills from which emerge a pair of hands making a tortilla. The site of the modern city did not have a settlement for most of the pre Hispanic era. The area was ruled by a coalition of four dominions called Tepeticpac, Ocotelolco, Tizatlan a ...

Peroxidase
Peroxidases or peroxide reductases ( EC numberbr>1.11.1.x are a large group of enzymes which play a role in various biological processes. They are named after the fact that they commonly break up peroxides. Functionality Peroxidases typically catalyze a reaction of the form: :ROOR' + \overset + 2H+ -> ce + R'OH Optimal substrates For many of these enzymes the optimal substrate is hydrogen peroxide, but others are more active with organic hydroperoxides such as lipid peroxides. Peroxidases can contain a heme cofactor in their active sites, or alternately redox-active cysteine or selenocysteine residues. The nature of the electron donor is very dependent on the structure of the enzyme. * For example, horseradish peroxidase can use a variety of organic compounds as electron donors and acceptors. Horseradish peroxidase has an accessible active site, and many compounds can reach the site of the reaction. * On the other hand, for an enzyme such as cytochrome c peroxidase, the c ...

Polycyclic Aromatic Hydrocarbon
A polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. The simplest representative is naphthalene, having two aromatic rings and the three-ring compounds anthracene and phenanthrene. PAHs are uncharged, non-polar and planar. Many are colorless. Many of them are found in coal and in oil deposits, and are also produced by the combustion of organic matter—for example, in engines and incinerators or when biomass burns in forest fires. Polycyclic aromatic hydrocarbons are discussed as possible starting materials for abiotic syntheses of materials required by the earliest forms of life. Nomenclature and structure The terms polyaromatic hydrocarbon or polynuclear aromatic hydrocarbon are also used for this concept. By definition, polycyclic aromatic hydrocarbons have multiple rings, precluding benzene from being considered a PAH. Some sources, such as the US EPA and CDC, consider naphthalene to be the simplest PA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ectomycorrhizae
An ectomycorrhiza (from Greek ἐκτός ', "outside", μύκης ', "fungus", and ῥίζα ', "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota. Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture. Unlike other mycorrhizal relationships, such as arbuscular mycorrhiza and ericoid mycorrhiza, ectomycorrhizal fungi do not penetrate their host's cell walls. Instead they form an entirely intercellular interface known as the Hartig net, consisting of highly branched hyphae formin ...

Great Plains
The Great Plains (french: Grandes Plaines), sometimes simply "the Plains", is a broad expanse of flatland in North America. It is located west of the Mississippi River and east of the Rocky Mountains, much of it covered in prairie, steppe, and grassland. It is the southern and main part of the Interior Plains, which also include the tallgrass prairie between the Great Lakes and Appalachian Plateau, and the Taiga Plains and Boreal Plains ecozones in Northern Canada. The term Western Plains is used to describe the ecoregion of the Great Plains, or alternatively the western portion of the Great Plains. The Great Plains lies across both Central United States and Western Canada, encompassing: * The entirety of the U.S. states of Kansas, Nebraska, North Dakota and South Dakota; * Parts of the U.S. states of Colorado, Iowa, Minnesota, Missouri, Montana, New Mexico, Oklahoma, Texas and Wyoming; * The southern portions of the Canadian provinces of Alberta, Saska ...

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska- Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. ...
