Sarcodon Scabrosus
''Hydnellum scabrosum'', also called bitter tooth or bitter hedgehog, is a species of tooth fungus in the family Bankeraceae. Taxonomy It was originally described by Swedish botanist Elias Fries as ''Hydnum scabrosum'' in 1836. Finnish mycologist Petter Karsten moved it to the genus ''Sarcodon'' in 1881. This species remained as ''Sarcodon scabrosus'' until 2019, when a molecular analysis using nuclear DNA showed that this and 11 other species lay genetically within the genus ''Hydnellum'', a genus of which harder woody flesh had previously been considered a distinguishing feature from soft-fleshed ''Sarcodon''. Within the genus it is most closely related to '' H. fennicum''. Description The fruit body (mushroom) has a convex to flattened brownish cap up to across that is covered with brown scales. It can be tinged with pink at the margins and darken with age. The mushroom has yellow-brown spines under the cap that are long and in diameter. They are decurrent to the stem. ...

Petter Adolf Karsten
Petter Adolf Karsten (16 February 1834 – 22 March 1917) was a Finnish mycologist, the foremost expert on the fungi of Finland in his day, and known in consequence as the "father of Finnish mycology". Karsten was born in Merimasku near Turku, studied at the University of Helsinki, and then moved to the inland of Tammela, where he spent most of his life with teaching botany and doing research at the Mustiala Agriculture Institute (now the Faculty of Agriculture of the HAMK University of Applied Sciences). He amassed a vast collection, both by his own efforts and those of his correspondents, and named about 200 new genera and 2,000 new species. In his mycological studies he extensively used the microscope and can be considered as the pioneer of fungal microscopy. ''Karstenia'', the international journal of mycology published by the Finnish Mycological Society, is dedicated to Karsten. Honours In 1885, botanist Elias Magnus Fries published ''Karstenia'' is a genus of fungi in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tooth Fungus
The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps (fruit bodies) producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus ''Hydnum'' ("hydnoid" means ''Hydnum''-like), but it is now known that not all hydnoid species are closely related. History ''Hydnum'' was one of the original genera created by Linnaeus in his ''Species Plantarum'' of 1753. It contained all species of fungi with fruit bodies bearing pendant, tooth-like projections. Subsequent authors described around 900 species in the genus. With increasing use of the microscope, it became clear that not all tooth fungi were closely related and most ''Hydnum'' species were gradually moved to other genera. The Dutch mycologist Rudolph Arnold Maas Geesteranus paid particular attention to the group, producing a series of papers reviewing the taxonomy of hydnoid fungi. The original genus ''Hydnum'' is ...

Bankeraceae
The ''Bankeraceae'' are a family of fungi in the order Thelephorales. Taxa are terrestrial, and ectomycorrhizal with plant species in families such as Pinaceae or Fagaceae. The family was circumscribed by Marinus Anton Donk in 1961. According to a 2008 estimate, the family contains 6 genera and 98 species. Genera The family consists of the following genera: * '' Bankera'' * '' Boletopsis'' * '' Corneroporus'' * '' Hydnellum'' * '' Phellodon'' * ''Sarcodon ''Sarcodon'' is a genus of fungi in the family Bankeraceae, which is part of the order Thelephorales The Thelephorales are an order of fungi in the class Agaricomycetes.

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elias 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 Botanical G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcodon
''Sarcodon'' is a genus of fungi in the family Bankeraceae, which is part of the order Thelephorales The Thelephorales are an order of fungi in the class Agaricomycetes. The order includes corticioid and hydnoid fungi, together with a few polypores and clavarioid species. Most fungi within the Thelephorales are ectomycorrhizal. None is of any ... known for its almost universal ectomycorrhizal life style. The genus owes its name to the presence of teeth-like spines on the hymenophore, it is derived from ancient Greek; ''sarco'' = flesh and ''odon'' = tooth. This is why they are commonly called "tooth fungi", or "Hydnoid fungi". Several species of the ''Sarcodon'' genus, including ''Sarcodon imbricatus'' (see figure), are edible. The fungus can be bitter, but that is less apparent in younger specimens. In China, it is a popular edible mushroom and it is used for lowering of cholesterol level, muscles relaxation and blood circulation. Isolates from the genus, called Scabroni ...

Hydnellum
''Hydnellum'' is a genus of tooth fungi in the family Bankeraceae (order Thelephorales). Widely distributed in the Northern Hemisphere, the genus contains around 40 species. The fruitbodies of its members grow by slowly enveloping nearby bits of grass and vegetation. There is great variability in the form of ''Hydnellum'' fruitbodies, which are greatly influenced by environmental conditions such as rainfall and humidity, drying winds, and temperature. They are too tough and woody to eat comfortably. Several species have become the focus of increasing conservation concern following widespread declines in abundance. ''Hydnellum'' species produce pigments that have been used to dye textiles. Several chemical compounds—some with unique biological activity—have been isolated and identified from the genus. One of the better-known species is the unusual pinkish-white ''Hydnellum peckii'', also known as "strawberries and cream" or as the "bleeding tooth fungus" due to the red d ...

Diterpenoid
Diterpenes are a class of chemical compounds composed of four isoprene units, often with the molecular formula C20H32. They are biosynthesized by plants, animals and fungi via the HMG-CoA reductase pathway, with geranylgeranyl pyrophosphate being a primary intermediate. Diterpenes form the basis for biologically important compounds such as retinol, retinal, and phytol. They are known to be antimicrobial and antiinflammatory. Structures As with most terpenes a huge number of potential structures exists, which may be broadly divided according to the number of rings present. Biosynthesis Diterpenes are derived from the addition of one IPP unit to FPP to form geranylgeranyl-pyrophosphate (GGPP). From GGPP, structural diversity is achieved mainly by two classes of enzymes; the diterpene synthases and cytochromes P450. Several diterpenes are produced by plants and cyanobacteria. GGPP is also the precursor for the synthesis of the phytane by the action of the enzyme geranylger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nerve Growth Factor
Nerve growth factor (NGF) is a neurotrophic factor and neuropeptide primarily involved in the regulation of growth, maintenance, proliferation, and survival of certain target neurons. It is perhaps the prototypical growth factor, in that it was one of the first to be described. Since it was first isolated by Nobel Laureates Rita Levi-Montalcini and Stanley Cohen in 1956, numerous biological processes involving NGF have been identified, two of them being the survival of pancreatic beta cells and the regulation of the immune system. Structure NGF is initially in a 7S, 130-kDa complex of 3 proteins – Alpha-NGF, Beta-NGF, and Gamma-NGF (2:1:2 ratio) when expressed. This form of NGF is also referred to as proNGF (NGF precursor). The gamma subunit of this complex acts as a serine protease, and cleaves the N-terminal of the beta subunit, thereby activating the protein into functional NGF. The term ''nerve growth factor'' usually refers to the 2.5S, 26-kDa beta subunit of the protein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrone
Pyrones or pyranones are a class of heterocyclic chemical compounds. They contain an unsaturated six-membered ring containing one oxygen atom and a ketone functional group. There are two isomers denoted as 2-pyrone and 4-pyrone. The 2-pyrone (or α-pyrone) structure is found in nature as part of the coumarin ring system. 4-Pyrone (or γ-pyrone) is found in some natural chemical compounds such as chromone, maltol and kojic acid. See also * Furanone 2-Furanone is a heterocyclic organic compound. It is also known as γ-crotonolactone (GCL), as it is formally the lactone derived from γ-hydroxyisocrotonic acid. The chemical is colloquially called "butenolide", and is the parent structure for th ..., which has one fewer carbon atom in the ring. References {{heterocyclic-stub ...

Sarcodon Imbricatus
''Sarcodon imbricatus'', commonly known as the shingled hedgehog or scaly hedgehog, is a species of tooth fungus in the order Thelephorales. The mushroom is edible. Many sources report it has a bitter taste, but others have found it delicious and suspect that the bitter specimens may be similar related species. The mushroom has a large, brownish cap with large brown scales and may reach 30 cm (12 in) in diameter. On the underside it sports greyish, brittle teeth instead of gills, and has white flesh. Its spore print is brown. It is associated with spruce ('' Picea''), appearing in autumn. It ranges throughout North America and Europe, although collections from the British Isles are now assigned to the similar species '' Sarcodon squamosus''. Taxonomy The Swedish botanist Olof Celsius reported in 1732 that ''Sarcodon imbricatus'' occurred in the vicinity of Uppsala, and Carl Linnaeus wrote of it in his 1737 work ''Flora lapponica''. It was one of the species initially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
