Dendrocollybia
''Dendrocollybia'' is a fungal genus in the family Tricholomataceae of the order Agaricales. It is a monotypic genus, containing the single species ''Dendrocollybia racemosa'', commonly known as the branched collybia or the branched shanklet. ''Dendrocollybia racemosa'' fruit bodies have small pale grayish-white or grayish-brown caps up to wide, and thin stems up to long. The species is characterized by its unusual stem, which is covered with short lateral branches. The branches often produce spherical slimeheads of translucent conidiophores on their swollen tips. The conidiophores produce conidia (asexual spores) by mitosis. Because the fungus can rely on either sexual or asexual modes of reproduction, fruit bodies sometimes have reduced or even missing caps. The unusual stems originate from black pea-sized structures called sclerotia. The anamorphic form of the fungus, known as '' Tilachlidiopsis racemosa'', is missing the sexual stage of its life cycle. It can reproduce at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collybia Tuberosa
''Collybia tuberosa'', commonly known as the lentil shanklet or the appleseed coincap, is a species of fungus in the family Tricholomataceae, and the type species of the genus '' Collybia''. The fungus produces small whitish fruit bodies with caps up to wide held by thin stems up to long. On the underside of the cap are closely spaced white gills that are broadly attached to the stem. At the base of the stem, embedded in the substrate is a small reddish-brown sclerotium that somewhat resembles an apple seed. The appearance of the sclerotium distinguishes it from the other two species of ''Collybia'', which are otherwise very similar in overall appearance. Like the two other members of its genus, ''C. tuberosa'' lives on the decomposing remains of other fleshy mushrooms. It is found in Europe, North America, and Japan, growing in dense clusters on species of ''Lactarius'' and ''Russula'', boletes, hydnums, and polypores. A 2023 chemical analysis found that this mus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collybia Cirrhata
''Collybia cirrhata'' is a species of fungus A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one ... in the family Tricholomataceae of the order Agaricales (gilled mushrooms). The species was first species description, described in the scientific literature in 1786, but was not valid name (botany), validly named until 1803. Found in Europe, Northern Eurasia, and North America, it is known from temperate, subarctic climate, boreal, and alpine climate, alpine or climate of the Arctic, arctic habitats. It is a saprobic species that grows in clusters on the decaying or blackened remains of other mushrooms. The basidiocarp, fruit bodies are small, with whitish convex to flattened pileus (mycology), caps up to in diameter, narrow white lamella (mycology), gills, and slender whitish stipe ( ...

Collybia Cookei
''Collybia cookei'' is a species of fungus in the family Tricholomataceae, and one of three species in the genus ''Collybia''. It is known from Europe, Asia, and North America. The fungus produces fruit bodies that usually grow on the decomposing remains of other mushrooms, like ''Meripilus giganteus'', ''Inonotus hispidus'', or species of ''Russula''; occasionally fruit bodies are found on rich humus or well-decayed wood. The fungus produces small white mushrooms with caps up to in diameter, supported by thin stems that originate from a yellowish-brown sclerotium. The mushroom is difficult to distinguish from the other two species of ''Collybia'' unless an effort is made to examine the sclerotia, which is usually buried in the substrate. The edibility of the mushroom has not been determined. Taxonomy and phylogeny The species was first described in the scientific literature in 1928 as ''Collybia cirrhata'' var. ''cookei'' by the Italian mycologist Giacomo Bresadola. In a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Hendrik Persoon
Christiaan Hendrik Persoon (31 December 1761 – 16 November 1836) was a Cape Colony mycologist who is recognized as one of the founders of mycology, mycological Taxonomy (biology), taxonomy. Early life Persoon was born in Cape Colony at the Cape of Good Hope, the third child of an immigrant Pomeranian father, Christiaan Daniel Persoon, and Netherlands, Dutch mother, Wilhelmina Elizabeth Groenwald. His mother died soon after he was born. In 1775, at the age of thirteen, he was sent to Europe for his education. His father died a year later in 1776. Education Initially a student of theology at University of Halle-Wittenberg, Halle, Persoon switched his studies to medicine, which he pursued in Leiden and then Göttingen. He received a doctorate from the German National Academy of Sciences Leopoldina, Deutsche Akademie der Naturforscher in Erlangen 1799. Later years He moved to Paris by 1803, where he spent the rest of his life, renting the upper floor of a house in a poor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clitocybe Dealbata
''Clitocybe'' is a genus of mushrooms characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter. There are estimated to be around 300 species in the widespread genus. ''Clitocybe'' means ''sloping head''. A few members of the genus are considered edible; many others are poisonous, containing the toxin muscarine among others. Distinguishing individual species of ''Clitocybe'' is generally prohibitively difficult to non-experts, requiring the analysis of microscopic characters. Therefore, with the exception of a few charismatic and readily identified members, ''Clitocybe'' mushrooms are rarely collected for consumption. Taxonomy ''Clitocybe'' was originally proposed by Elias Fries in 1821 as a tribe in the genus ''Agaricus''. Friedrich Staude elevated it to generic status in 1857. Recent molecular work has shown the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regional Red List
A Regional Red List is a report of the threatened status of species within a certain country or region. It is based on the IUCN Red List of Threatened Species, an inventory of the conservation status of species on a global scale. Regional Red Lists assess the risk of extinction to species within a political management unit and therefore may feed directly into national and regional planning. This project is coordinated by the Zoological Society of London, the World Conservation Union (IUCN) and partners in national governments, universities and organizations throughout the world. Regional Red Lists may assist countries or regions in: * Determining the conservation status and trends of species * Identifying species or ecosystems under greatest threat * Informing conservation planning and priority setting * Raising awareness of threatened species Assessing extinction risk on a regional scale The IUCN Categories and Criteria were initially designed to assess the conservation ...

Pacific Northwest
The Pacific Northwest (PNW; ) is a geographic region in Western North America bounded by its coastal waters of the Pacific Ocean to the west and, loosely, by the Rocky Mountains to the east. Though no official boundary exists, the most common conception includes the U.S. states of Oregon, Washington (state), Washington, Idaho, and the Canadian province of British Columbia. Some broader conceptions reach north into Alaska and Yukon, south into Northern California, and east into western Montana. Other conceptions may be limited to the coastal areas west of the Cascade Mountains, Cascade and Coast Mountains, Coast mountains. The Northwest Coast is the coastal region of the Pacific Northwest, and the Northwest Plateau (also commonly known as "British Columbia Interior, the Interior" in British Columbia), is the inland region. The term "Pacific Northwest" should not be confused with the Northwest Territory (also known as the Great Northwest, a historical term in the United States) ...

Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the equator. For other planets in the Solar System, north is defined by humans as being in the same celestial sphere, celestial hemisphere relative to the invariable plane of the Solar System as Earth's North Pole. Due to Earth's axial tilt of 23.439281°, there is a seasonal variation in the lengths of the day and night. There is also a seasonal variation in temperatures, which lags the variation in day and night. Conventionally, winter in the Northern Hemisphere is taken as the period from the December solstice (typically December 21 UTC) to the March equinox (typically March 20 UTC), while summer is taken as the period from the June solstice through to the September equinox (typically on 23 September UTC). The dates vary each year due to the difference between the calendar year and the Year#Astronomical years, astronomical year. Within the Northern Hemisphere, oceanic currents can change the weather patterns that aff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Host (biology)
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasite, parasitic, a mutualism (biology), mutualistic, or a commensalism, commensalist ''guest'' (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cell (biology), cells harbouring pathogenic (disease-causing) viruses, or a Fabaceae, bean plant hosting mutualistic (helpful) Rhizobia, nitrogen-fixing bacteria. More specifically in botany, a host plant supplies nutrient, food resources to micropredators, which have an evolutionarily stable strategy, evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. Symbiosis Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an ...

Russula
''Russula'' is a very large genus composed of around 750 worldwide species of fungi. The genus was described by Christian Hendrik Persoon in 1796. The mushrooms are fairly large, and brightly colored – making them one of the most recognizable genera among mycologists and mushroom collectors. Their distinguishing characteristics include usually brightly coloured caps, a white to dark yellow spore print, brittle, attached gills, an absence of latex, and absence of partial veil or volva tissue on the stem. Microscopically, the genus is characterised by the amyloid ornamented spores and flesh (trama) composed of spherocysts. Members of the related genus ''Lactarius'' have similar characteristics but emit a milky latex when their gills are broken. The ectomycorrhizal mushrooms are typically common. Although some species are toxic, a number of others are edible. Taxonomy Christian Hendrik Persoon first circumscribed the genus ''Russula'' in his 1796 work ''Observationes Mycologi ...

Lactarius (fungus)
''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".
