Honey Fungus
''Armillaria'' is a genus of fungi that includes the '' A. mellea'' species ('honey fungus') that live on trees and woody shrubs. It includes about 10 species formerly categorized summarily as ''A. mellea''. ''Armillaria'' sp. are long-lived and form the largest living fungi in the world. The largest known specimen (an ''A. ostoyae'') covers more than in Oregon and is estimated to be 2,500 years old. Some species of ''Armillaria'' display bioluminescence. ''Armillaria'' can be a destructive forest pathogen. It causes "white rot" root disease. As it feeds on dead plant material, it can kill its host with little negative effect to itself. Taxonomy The name ''Armillaria'' was defined in 1821 by Elias Magnus Fries, but at that time most gilled mushrooms were considered to belong to genus ''Agaricus'' and ''Armillaria'' was only a subgenus (a "tribe"). In 1857, Friedrich Staude established the independent genus. ''Armillaria'' species morphologically similar to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armillaria Mellea
''Armillaria mellea'', commonly known as honey fungus, is an edible basidiomycete fungus in the genus ''Armillaria''. It is a plant pathogen and part of a cryptic species complex of closely related and Morphology (biology), 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, Forest dieback, dieback of the branches and death. The mycelium is capable of producing light via bioluminescence. The mushroom is widely distributed in temperate regions of the Northern Hemisphere. It typically grows 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 melleus'' by Danish-Norwegian botanist Martin Vahl in 1790; it was transferred to the genus ''Armillaria'' in 1871 by Paul Kummer.

Nomenclature Committee For Fungi
International Botanical Congress (IBC) is an international meeting of botanists in all scientific fields, authorized by the International Association of Botanical and Mycological Societies (IABMS) and held every six years, with the location rotating between different continents. The current numbering system for the congresses starts from the year 1900; the XX IBC was in Madrid, Spain, July 2024. The XXI IBC is planned to be in Cape Town, South Africa, in July 2029. The IBC has the power to alter the ICN (International Code of Nomenclature for algae, fungi, and plants), which was renamed from the International Code of Botanical Nomenclature (ICBN) at the XVIII IBC. Formally the power resides with the Plenary Session; in practice this approves the decisions of the Nomenclature Section. The Nomenclature Section meets before the actual Congress and deals with all proposals to modify the Code: this includes ratifying recommendations from sub-committees on conservation. To reduce the ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Code Of Nomenclature For Algae, Fungi, And Plants
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. For fungi the ''Code'' was revised by the ''San Juan Chapter F'' in 2018. The 2025 edition of ICBN, the ''Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycelial
Mycelium (: mycelia) is a root-like structure of a fungus consisting of a mass of branching, thread-like hyphae. Its normal form is that of branched, slender, entangled, anastomosing, hyaline threads. Fungal colonies composed of mycelium are found in and on soil and many other substrates. A typical single spore germinates into a monokaryotic mycelium, which cannot reproduce sexually; when two compatible monokaryotic mycelia join and form a dikaryotic mycelium, that mycelium may form fruiting bodies such as mushrooms. A mycelium may be minute, forming a colony that is too small to see, or may grow to span thousands of acres as in '' Armillaria''. Through the mycelium, a fungus absorbs nutrients from its environment. It does this in a two-stage process. First, the hyphae secrete enzymes onto or into the food source, which break down biological polymers into smaller units such as monomers. These monomers are then absorbed into the mycelium by facilitated diffusion and active t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizomorpha
''Rhizomorpha'' is a genus of fungi that was created for species known only by their mycelial cords ("rhizomorphs") and so impossible to classify within the normal taxonomic system, which is based on reproductive structures. Origin and naming Mycelial cords, or rhizomorphs, are long strands sent out by some fungi to colonize new space and absorb nutrients. They typically run along the ground or under bark, but may also hang in the air. They are complex structures, big enough to be seen with the naked eye, and they should not be confused with the microscopic thread-like cells (hyphae) of which they are composed. Fungi are generally classified according to their sexual or asexual spore-bearing organs (including fruiting bodies where present), but where only sterile rhizomorphs were available, such species were put into genus ''Rhizomorpha'' even if they were not genetically related. The genus was created in 1791 by Albrecht Wilhelm Roth for an observation of material in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albrecht Wilhelm Roth
Albrecht Wilhelm Roth (6 January 1757 – 16 October 1834) was a physician and botanist born in Dötlingen, Germany. He studied medicine at the Universities of University of Halle, Halle and University of Erlangen, Erlangen, where he received his doctorate in 1778. After graduation, he practiced medicine in Dötlingen, and shortly afterwards relocated to Bremen-Vegesack. From 1785 to 1787 he issued an exsiccata under the title ''Herbarium vivum plantarum officinalium nebst einer Anweisung Pflanzen zum medizinischen Gebrauche zu sammeln''. Roth is remembered for his influential scientific publications, particularly in the field of botany. His botanical research and writings came to the attention of Johann Wolfgang von Goethe (1749–1832), who recommended Roth to a position at the botanical institute at the University of Jena. Two of his better written works were ''Tentamen florae germanica'' (a treatise on German flora), and ''Novae plantarum species praesertim Indiae orientalis ...

Pine Point, Northwest Territories
Pine Point is an abandoned locality that formerly held town status near the south shore of Great Slave Lake between the towns of Hay River and Fort Resolution in the Northwest Territories of Canada. It was built to serve the work force at the Pine Point Mine, an open-pit mine that produced lead and zinc ores. The town's population peaked at 1,915 in 1976, but was abandoned and deconstructed in 1988 after the mine closed in 1987. History Construction of both the Pine Point mine and the community commenced in 1962. Pine Point incorporated as a town on April 1, 1974. The mine was closed in 1987, forcing the single-industry town to close in 1988. Mike Lenton was the town's last mayor. Pine Point houses were sold cheaply, and many of the buildings were then moved to Fort Resolution (including the ice arena), Hay River and northern Alberta while the remaining buildings were demolished. The Town of Pine Point was absorbed into Unorganized Fort Smith on January 1, 1996. Today ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Root Rot
Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots.-Hydroponics Root Rot: What is It, How To Treat It, How to Prevent It''Origin Hydroponics.'' June 2, 2018 Root Rot In Your Hydroponic System: 4 Reasons (+ Solutions)''YOUR INDOOR HERBS AND GARDEN. n.d'' Tips For Preventing Root Rot In Hydroponics''Fresh Air With Housplants''. February 3, 2022. It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with poor drainage. The leaves of plants experiencing root rot often yellow and die, and if allowed to continue, the condition can be fatal to the plant. To avoid root rot, it is best to only water plants when the soil becomes dry, and to put the plant in a well-drained pot. Using a dense potting media such as one dug up from outdoors can also cause root ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
