Armillaria Mellea
''Armillaria mellea'', commonly known as honey fungus, is a basidiomycete fungus in the genus ''Armillaria''. It is a plant pathogen and part of a cryptic species complex of closely related and morphologically similar species. It causes Armillaria root rot in many plant species and produces mushrooms around the base of trees it has infected. The symptoms of infection appear in the crowns of infected trees as discoloured foliage, reduced growth, dieback of the branches and death. The mushrooms are edible but some people may be intolerant to them. This species is capable of producing light via bioluminescence in its mycelium. ''Armillaria mellea'' is widely distributed in temperate regions of the Northern Hemisphere. The fruit body or mushroom, commonly known as stump mushroom, stumpie, honey mushroom, pipinky or pinky, grows typically on hardwoods but may be found around and on other living and dead wood or in open areas. Taxonomy The species was originally named ''Agaricus m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin Vahl
Martin Henrichsen Vahl (10 October 1749 – 24 December 1804) was a Danish-Norwegian botanist, herbalist and zoologist. Biography Martin Vahl was born in Bergen, Norway and attended Bergen Cathedral School. He studied botany at the University of Copenhagen and at Uppsala University under Carl Linnaeus.

Bioluminescence
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus '' Vibrio''; in others, it is autogenic, produced by the animals themselves. In a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin. In some species, the luciferase requires other cofactors, such as calcium or magnesium ions, and so ...

Armillaria Tabescens
''Armillaria tabescens'' (also known as ringless honey mushroom) is a species of fungus in the family Physalacriaceae. It is a plant pathogen. The mycelium of the fungus is bioluminescent. Hosts and symptoms ''Armillaria'' species infect a wide variety of woody plants. In a survey of 250 permanent plots of trees in Albania, ''Armillaria tabescens'' affected multiple species of trees including fir species, where it invaded when the plant was stressed. Tsopelas et al. reported ''Armillaria tabescens'' to be more prevalent in areas where the trees were stressed due to limited moisture. In oak trees, it was slightly more damaging and could kill young trees. ''Armillaria tabescens'' was also recorded in poplar and eucalyptus plantations, and almond trees were found to be very susceptible to infection. The results of the study by Lushaj et al. showed that ''Armillaria tabescens'' was most frequently recorded on fruit and ornamental trees compared to the other species''.'' ''Arm ...

Carleton Rea
Carleton Rea (7 May 1861 – 26 June 1946) was an English mycologist, botanist, and naturalist. Background and education Carleton Rea was born in Worcester, the son of the City Coroner. He was educated at The King's School and Magdalen College, Oxford, where he studied law. He entered the Inner Temple and became a barrister in the Oxford Circuit, but never pursued his career with undue enthusiasm and ceased taking cases by 1907. Natural history and mycology In the words of John Ramsbottom, Rea was "active in his leisure" and devoted much of his time to natural history, having joined his local Worcestershire Naturalists' Club as a schoolboy (he was president of the club in its centenary year, at the time of his death). He collaborated with John Amphlett in the ''Botany of Worcestershire'', published in 1909, and wrote several later supplements. His first paper in 1892 was on rare plants of the Severn Valley. Rea's special interest was in fungi and in 1896 he was one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scop
A ( or ) was a poet as represented in Old English poetry. The scop is the Old English counterpart of the Old Norse ', with the important difference that "skald" was applied to historical persons, and scop is used, for the most part, to designate oral poets ''within'' Old English literature. Very little is known about scops, and their historical existence is questioned by some scholars. Functions The scop, like the similar gleeman, was a reciter of poetry. The scop, however, was typically attached to a court on a relatively permanent basis. There, he most likely received rich gifts for his performances. The performances often featured the recitation of recognisable texts such as the "old pagan legends of the Germanic tribes." However, the scop's duties also included ''composing'' his own poetry in different situations, the eulogizing of his master. While some scops moved from court to court, they were (generally speaking) less nomadic than the gleemen and had positions of gr ...

Armillaria Solidipes
''Armillaria ostoyae'' (synonym ''Armillaria solidipes'') is a species of fungus (mushroom), pathogenic to trees, in the family Physalacriaceae. In the western United States, it is the most common variant of the group of species under the name ''Armillaria mellea''. ''A. ostoyae'' is common on both hardwood and conifer wood in forests west of the Cascade Range in Oregon, United States. It has decurrent gills and the stipe has a ring. The mycelium invades the sapwood and is able to disseminate over great distances under the bark or between trees in the form of black rhizomorphs ("shoestrings"). In most areas of North America, ''Armillaria ostoyae'' can be separated from other species by its physical features: cream-brown colors, prominent cap scales, and a well-developed stem ring distinguish it from other ''Armillaria''. ''Armillaria ostoyae'' grows and spreads primarily underground, such that the bulk of the organism is not visible from the surface. In the autumn, the s ...

Charles Horton Peck
Charles Horton Peck (March 30, 1833 – July 11, 1917) was an American mycologist of the 19th and early 20th centuries. He was the New York State Botanist from 1867 to 1915, a period in which he described over 2,700 species of North American fungi. Biography Charles Horton Peck was born on March 30, 1833, in the northeastern part of the town Sand Lake, New York, now called Averill Park. After suffering a light stroke early in November 1912 and then a severe stroke in 1913, he died at his house in Menands, New York, on July 11, 1917. In 1794, Eleazer Peck (his great grandfather) moved from Farmington, Conn. to Sand Lake, NY attracted by oak timber that was manufactured for the Albany market. Later on, Pamelia Horton Peck married Joel B., both from English descent, and became Charles Peck parents (Burnham 1919; Atkinson 1918). Even though his family was rich and locally prominent, his education was provincial (Haines 1986). During his childhood, he used to enjoy fishing and ...

Taxon
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
