Lactarius Quietus
''Lactarius quietus'' (commonly known as the oak milkcap, oakbug milkcap or southern milkcap) is a mushroom of the genus ''Lactarius''. It is easily identified by its oily scent and the concentric bands on its cap. It is brown, and is probably named after its matt, "quiet" surface and colouration. It is found exclusively under oak trees in Europe, where it grows solitarily or in scattered groups in autumn months. In North America, the variety ''L. quietus'' var. ''incanus'' is fairly common in the same habitat. The mushroom's edibility is disputed. Taxonomy and naming ''Lactarius quietus'' was first described and named by Swedish mycologist Elias Magnus Fries, who named it ''Agaricus quietus'' in the first volume of his ''Systema Mycologicum'', published in 1821. In his later ''Epicrisis Systematis Mycologici'', published in 1838, Fries transferred the species to ''Lactarius''. Subsequent attempts to reclassify the species were unsuccessful; in 1871, Paul Kummer described the s ... [...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] |
Cinnamon
Cinnamon is a spice obtained from the inner bark of several tree species from the genus ''Cinnamomum''. Cinnamon is used mainly as an aromatic condiment and flavouring additive in a wide variety of cuisines, sweet and savoury dishes, breakfast cereals, snack foods, bagels, teas, and traditional foods. The aroma and flavour of cinnamon derive from its essential oil and principal component, cinnamaldehyde, as well as numerous other constituents including eugenol. Cinnamon is the name for several species of trees and the commercial spice products that some of them produce. All are members of the genus ''Cinnamomum'' in the family Lauraceae. Only a few ''Cinnamomum'' species are grown commercially for spice. ''Cinnamomum verum'' (AKA ''C. zeylanicum''), known as "Ceylon cinnamon" after its origins in Sri Lanka (formerly Ceylon), is considered to be "true cinnamon", but most cinnamon in international commerce is derived from four other species, usually and more correctly refe ...

Mycorrhizal
A mycorrhiza (from Greek μύκης ', "fungus", and ῥίζα ', "root"; pl. mycorrhizae, mycorrhiza or mycorrhizas) is a symbiotic association between a fungus and a plant. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play important roles in plant nutrition, soil biology, and soil chemistry. In a mycorrhizal association, the fungus colonizes the host plant's root tissues, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in ectomycorrhizal fungi. The association is sometimes mutualistic. In particular species or in particular circumstances, mycorrhizae may have a parasitic association with host plants. Definition A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules such as sugars by photosynthesis and supplies them to the fungus, and the fungus supplies to the plant water and mineral nutrients, such as phos ...

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] |
University Press Of Kentucky
The University Press of Kentucky (UPK) is the scholarly publisher for the Commonwealth of Kentucky, and was organized in 1969 as successor to the University of Kentucky Press. The university had sponsored scholarly publication since 1943. In 1949, the press was established as a separate academic agency under the university president, and the following year Bruce F. Denbo, then of Louisiana State University Press, was appointed as the first full-time professional director. Denbo served as director of UPK until his retirement in 1978, building a small but distinguished list of scholarly books with emphasis on American history and literary criticism. Since its reorganization, the Press has represented a consortium that now includes all of Kentucky's state universities, seven of its private colleges, and two historical societies. UPK joined the Association of University Presses in 1947. The press is supported by the Thomas D. Clark Foundation, a private nonprofit foundation establis ...

Lactarius Mutabilis
''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 macromorpholog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactarius Aquifluus
''Lactarius helvus'', commonly known as fenugreek milkcap, is a member of the large milkcap genus ''Lactarius'' in the order Russulales. Fruiting bodies can be found in '' Sphagnum'' moss in coniferous and deciduous woodland in Europe, and possibly North America, although considerable debate continues about the North American variety, formerly referred to as ''Lactarius aquifluus''. Mushrooms are pale brown-grey or beige in colour and funnel-shaped, with colourless, watery milk. Its distinctive smell has been likened to fenugreek, celery, liquorice, or Maggi instant soup. Mildly toxic when raw, it has been implicated in the poisoning of 418 people near Leipzig in October 1949. However, it is used in small quantities as a spice when dried. Sotolon, the agent that gives the fungus its odour, also occurs in fenugreek, maple syrup and lovage. The possible North American variety has a more salmon to pink color with scant watery milk and a strong smell of maple syrup or caramel. In Que ...

Maple Syrup
Maple syrup is a syrup made from the sap of maple trees. In cold climates, these trees store starch in their trunks and roots before winter; the starch is then converted to sugar that rises in the sap in late winter and early spring. Maple trees are tapped by drilling holes into their trunks and collecting the sap, which is processed by heating to evaporate much of the water, leaving the concentrated syrup. Maple syrup was first made by the Indigenous peoples of North America. The practice was adopted by European settlers, who gradually changed production methods. Technological improvements in the 1970s further refined syrup processing. Virtually all of the world's maple syrup is produced in Canada and the United States. The Canadian province of Quebec is the largest producer, responsible for 70 percent of the world's output; Canadian exports of maple syrup in 2016 were Canadian dollar, C$487 million (about United States dollar, US$360 million), with Quebec accounting for some 9 ...

Bed Bug (insect)
''Cimex'' is a genus of insects in the family Cimicidae. ''Cimex'' species are ectoparasites that typically feed on the blood of birds and mammals. Two species, ''Cimex lectularius'' and ''Cimex hemipterus'', are known as bed bugs and frequently feed on humans, although other species may parasitize humans opportunistically. Species that primarily parasitize bats are known as bat bugs. The insects are long and have flattened reddish-brown bodies with small nonfunctional wings. Description Adult ''Cimex'' are light brown to reddish-brown, flat and oval. The mouthparts are beak-like, and adapted for piercing and sucking. Following a blood meal the abdomen is plump and darker in colour. The front wings are vestigial and reduced to pad-like structures and there are no hind wings. ''Cimex'' have segmented abdomens with microscopic hairs that give them a banded appearance. Adults grow to long. The different species are very similar in morphology and can only be separated by micr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non-vulcanized rubber. Such is the case in products like latex gloves, latex condoms ...

Lamella (mycology)
In mycology, a lamella, or gill, is a papery hymenophore rib under the cap of some mushroom species, most often agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, ''Lactarius'' species typically seep latex from their gills. It was originally believed that all gilled fungi were Agaricales, but as fungi were studied in more detail, some gilled species were demonstrated not to be. It is now clear that this is a case of convergent evolution (i.e. gill-like structures evolved separately) rather than being an anatomic feature that evolved only once. The apparent reason that various basidiomycetes have evolved gills is that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
