Russula Mairei
Formerly ''Russula mairei'' (Singer), and commonly known as the beechwood sickener, the now re-classified fungus ''Russula nobilis'' (Velen.) is a basidiomycete mushroom of the genus ''Russula''. This group of mushrooms are noted for their brittle gills and bright colours. Taxonomy It was previously named in honour of French mycologist René Maire by Rolf Singer in 1929, but found to be the same taxon as the earlier 1920 ''Russula nobilis'', which has naming priority. Description The cap is a red or rosy colour, 3–6 cm wide, convex to flat, or slightly depressed, and weakly sticky. It peels only to a third of its radius, which reveals pink flesh. The flesh is firm and white or sometimes yellowish, smells of coconut, and tastes peppery. It is often damaged by slugs. The stem is 2–5 cm long, 1–1.5 cm wide, cylindrical, (firmer than its conifer dwelling namesake, ''Russula emetica''), and white. The gills are narrowly spaced, adnexed, rounded, and white, often ...

Josef Velenovský
Josef Velenovský (22 April 1858 – 7 May 1949) was a Czech botanist, mycologist, pteridologist, and bryologist. He also worked with fossils. He was a research investigator and professor in the Botanical Institute of the University of Prague, alternating with his colleague Ladislav Josef Čelakovský. He was also professor of botany at Charles University, where he concentrated in the study of mycology in the final half of his life. Velenovský collected innumerable specimens, particularly in new central Bohemia. He was a prolific author (or coauthor) of new fungal species, having formally described about 2700 in his career. Many of his type specimens and other collections are located in the herbarium of the Národní Museum of Prague.

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Fungi Described In 1920
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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 motility, 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Russula Sardonia
''Russula sardonia'', commonly known as the primrose brittlegill, is a mushroom of the genus ''Russula'', which are commonly known as brittlegills. The fruiting body, or mushroom, is a reddish-purple, the colour of blackberry juice, and is found in coniferous woodland in summer and autumn. It is inedible, and like many inedible members of the genus, has a hot, peppery taste. Taxonomy It was given its present binomial name by the eminent Swedish mycologist Elias Magnus Fries in 1838. The specific epithet ''sardonia'', from the Greek, means bitter or acrid, and is a reference to its taste. ''Russula drimeia'' described by Mordecai Cubitt Cooke in 1881, ''R. chrysodacryon'' by Rolf Singer in 1923, and ''R. emeticiformis'' by William Alphonso Murrill in 1938, are synonyms. The name has also been applied to what is now considered ''R. queletii''. Description The cap grows to around in diameter. It is commonly purplish-red, but brownish, and greenish forms have been r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactarius (fungus)
''Lactarius'' is a genus of mushroom-producing, ectomycorrhizal fungi, containing several edible species. The species of the genus, commonly known as milk-caps, are characterized by the milky fluid ("latex") they exude when cut or damaged. Like the closely related genus '' Russula'', their flesh has a distinctive brittle consistency. It is a large genus with over 500 known species, mainly distributed in the Northern hemisphere. Recently, the genus '' Lactifluus'' has been separated from ''Lactarius'' based on molecular phylogenetic evidence. Systematics and taxonomy The genus ''Lactarius'' was described by Christian Hendrik Persoon in 1797 with '' L. piperatus'' as the original type species. In 2011, '' L. torminosus'' was accepted as the new type of the genus after the splitting-off of ''Lactifluus'' as separate genus. The name "''Lactarius''" is derived from the Latin '' lac'', "milk".

Sesquiterpene
Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids. It is estimated (2006) that 3000 sesquiterpenes have been identified. Biosynthesis and examples The reaction of geranyl pyrophosphate with isopentenyl pyrophosphate results in the 15-carbon farnesyl pyrophosphate (FPP), which is an intermediate in the biosynthesis of sesquiterpenes such as farnesene. Cyclic sesquiterpenes are more common than cyclic monoterpenes because of the increased chain length and additional double bond in the sesquiterpene precursors. In addition to common six-membered ring systems such as the ones found in zingiberene and bisacurone, cyclization of one end of the chain to the other end can lead to macrocyclic rings such as humulene. ...

Colic
Colic or cholic () is a form of pain that starts and stops abruptly. It occurs due to muscular contractions of a hollow tube (small and large intestine, gall bladder, ureter, etc.) in an attempt to relieve an obstruction by forcing content out. It may be accompanied by sweating and vomiting. Types include: *Baby colic, a condition, usually in infants, characterized by incessant crying * Biliary colic, blockage by a gallstone of the common bile duct or cystic duct * Devon colic or painter's colic, a condition caused by lead poisoning *Horse colic, a potentially fatal condition experienced by horses, caused by intestinal displacement or blockage * Renal colic, a pain in the flank, characteristic of kidney stone Kidney stone disease (known as nephrolithiasis, renal calculus disease, or urolithiasis) is a crystallopathy and occurs when there are too many minerals in the urine and not enough liquid or hydration.
