Lactarius Pyrogalus
''Lactarius pyrogalus'', commonly known as the fire-milk lactarius, is a species of inedible mushroom in genus ''Lactarius (fungus), Lactarius''. It is greyish and differentiated from other grey ''Lactarius'' by its widely spaced, yellow gills. It is found on the forest floor in mixed woodland, especially at the base of hazel trees. Taxonomy ''Lactarius pyrogalus'' was first described by French mycologist Jean Baptiste François Pierre Bulliard, Pierre Bulliard as ''Agaricus pyrogalus'' in 1792, before being given its current binomial name by Swedish mycologist Elias Magnus Fries in 1838. Description ''Lactarius pyrogalus'' has a cap across which is grey fawn, sometimes with a yellowish tinge, with pink and purple tinges not unknown. It is flattened convex to flat, later becoming funnel shaped. The cap is sometimes faintly concentrically banded, it is thin fleshed and becomes sticky when moist, but is not shiny. The stem is between 4 and 6 cm, and between 7 and 15 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Baptiste François Pierre Bulliard
Jean Baptiste François Pierre Bulliard (also Pierre Bulliard; 24 November 1752, in Aubepierre-sur-Aube Haute-Marne – 26 September 1793, in Paris) was a French physician and botanist. Bulliard studied in Langres, where he became interested in natural history, and afterwards a position was obtained for him in the abbey in Ville-sous-la-Ferté, Clairvaux and later he moved to Paris where he study medicine. There he also practiced as a physician. He tutored the son of General :fr:Claude Dupin, Claude Dupin (1686-1769). He was an able draughtsman and also learnt to engrave. He invented a way of printing natural history plates in colour and used the method in his own publications. In 1779 he commenced a work on the poisonous plants of France. It was seized by the police on the grounds that it was a dangerous work. Bulliard's ''Dictionnaire Elémentaire de Botanique'' (1783) contributed to the spreading and consolidation of botanical terminology and the Linnaean taxonomy, Linné ...

Amyloid
Amyloids are aggregates of proteins characterised by a Fibril, fibrillar morphology of 7–13 Nanometer, nm in diameter, a beta sheet (β-sheet) Secondary structure of proteins, secondary structure (known as cross-β) and ability to be Staining, stained by particular dyes, such as Congo red. In the human body, amyloids have been linked to the development of various diseases. Pathogenic amyloids form when previously healthy proteins lose their normal Protein structure, structure and physiology, physiological functions (Protein misfolding, misfolding) and form fibrous deposits in amyloid plaques around cells which can disrupt the healthy function of tissues and organs. Such amyloids have been associated with (but not necessarily as the cause of) more than 50 human diseases, known as amyloidosis, and may play a role in some neurodegenerative diseases. Some of these diseases are mainly sporadic and only a few cases are Genetic disorder, familial. Others are only Genetic disorder, fam ...

Lactarius
''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". Placement within Russulaceae Molecular phylogenetics uncovered that, while macromorphologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lactarius Deliciosus
''Lactarius deliciosus'', commonly known as the saffron milk cap and red pine mushroom, is one of the best known members of the large milk-cap genus ''Lactarius'' in the order Russulales. It is native to Europe, but has been accidentally introduced to other countries along with pine trees, with which the fungus is symbiotic. Taxonomy The species was known to Carl Linnaeus, who officially described it in the second volume of his ''Species Plantarum'' in 1753, giving it the name ''Agaricus deliciosus''. The specific epithet is derived from Latin ''deliciosus'', meaning "tasty". The Swedish taxonomist allegedly gave the species its epithet after smelling it and presuming it tasted good, perhaps confusing it with a Mediterranean milk cap regarded for its flavor. Dutch mycologist Christian Hendrik Persoon added the varietal epithet ''lactifluus'' in 1801, before English mycologist Samuel Frederick Gray placed it in its current genus, ''Lactarius'', in 1821 in his ''The Natural Arra ...

Coppice
Coppicing is a traditional method of woodland management which exploits the capacity of many species of trees to put out new shoots from their stump or roots if cut down. In a coppiced wood, which is called a copse, young tree stems are repeatedly cut down to near ground level, resulting in a stool. New growth emerges, and after a number of years, the coppiced tree is harvested, and the cycle begins anew. Pollarding is a similar process carried out at a higher level on the tree in order to prevent grazing animals from eating new shoots. ''Daisugi'' (台杉, where ''sugi'' refers to Japanese cedar), is a similar Japanese technique. Many silviculture practices involve cutting and regrowth; coppicing has been of significance in many parts of lowland temperate Europe. The widespread and long-term practice of coppicing as a landscape-scale industry is something that remains of special importance in southern England.

Frances Lincoln
Frances Elisabeth Rosemary Lincoln (20 March 1945 – 26 February 2001) was an English independent publisher of illustrated books. She published under her own name and the company went on to become Frances Lincoln Publishers. In 1995, Lincoln won the ''Woman of the Year for Services to Multicultural Publishing'' award. Education Frances Lincoln went "unhappily" to school in Bedford, moving after a year to St George's School, Harpenden, where she became Head Girl. Her university education was at Somerville College, Oxford. (Somerville at that time was a women's college, known in Oxford as "the bluestocking college".) There she read Greats (the Oxford term for traditional courses in the humanities, with emphasis on the ancient classics of Greece and Rome, including philosophy). A fellow-student, the drug smuggler Howard Marks, described her as "vivacious" in his 1996 autobiography '' Mr. Nice''. Career In 1970, Lincoln started work as an Assistant Editor at the London-based p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melzer's Reagent
Melzer's reagent (also known as Melzer's iodine reagent, Melzer's solution or informally as Melzer's) is a chemical reagent used by mycologists to assist with the identification of fungi, and by phytopathologists for fungi that are plant pathogens. Composition Melzer's reagent is an aqueous solution of chloral hydrate, potassium iodide, and iodine. Depending on the formulation, it consists of approximately 2.50-3.75% potassium iodide and 0.75–1.25% iodine, with the remainder of the solution being 50% water and 50% chloral hydrate. Melzer's is toxic to humans if ingested due to the presence of iodine and chloral hydrate. Due to the legal status of chloral hydrate, Melzer's reagent is difficult to obtain in the United States. In response to difficulties obtaining chloral hydrate, scientists at Rutgers formulated Visikol (compatible with Lugol's iodine) as a replacement. In 2019, research showed that Visikol behaves differently to Melzer’s reagent in several key situations, notin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. 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 obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botanica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
