Psilocybe Mushrooms
''Psilocybe'' ( ) is a genus of gilled mushrooms, growing worldwide, in the family Hymenogastraceae. Many species contain the psychedelic compounds psilocybin and psilocin. Taxonomy Taxonomic history A 2002 study of the molecular phylogeny of the agarics indicated the genus ''Psilocybe'' as then defined was polyphyletic, falling into two distinct clades that are not directly related to each other. The blue-staining hallucinogenic species constituted one clade and the non-bluing species the other. The previous type species of the genus, ''Psilocybe '' (now '' Deconica montana''), was in the non-bluing clade, but in 2010, the type species was changed to '' P. semilanceata'', a member of the bluing clade. A 2006 molecular phylogenetic study of the Agaricales by Matheny and colleagues, further demonstrated the separation of the bluing and non-bluing clades of ''Psilocybe'' in a larger, strongly supported phylogenetic tree of the Agaricales. ''Psilocybe'' had been placed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psilocybe Semilanceata
''Psilocybe semilanceata'', commonly known as the liberty cap, is a species of fungus which produces the psychoactive compounds psilocybin, psilocin and baeocystin. It is both one of the most widely distributed psilocybin mushrooms in nature, and one of the most potent. The mushrooms have a distinctive conical to bell-shaped cap, up to in diameter, with a small nipple-like protrusion on the top. They are yellow to brown, covered with radial grooves when moist, and fade to a lighter color as they mature. Their stipes tend to be slender and long, and the same color or slightly lighter than the cap. The gill attachment to the stipe is adnexed (narrowly attached), and they are initially cream-colored before tinting purple to black as the spores mature. The spores are dark purplish-brown en masse, ellipsoid in shape, and measure 10.5–15 by 6.5–8.5 μm. The mushroom grows in grassland habitats, especially wetter areas. Unlike '' P. cubensis'', the fungus doe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agaricales
The Agaricales are an order (biology), order of fungi in the division (mycology), division Basidiomycota. As originally conceived, the order contained all the agarics (gilled mushrooms), but subsequent research has shown that not all agarics are closely related and some belong in other orders, such as the Russulales and Boletales. Conversely, DNA research has also shown that many non-agarics, including some of the clavarioid fungi (clubs and corals) and gasteroid fungi (puffballs and false truffles) belong within the Agaricales. The order has 46 Extant taxon, extant family (biology), families, more than 400 genus, genera, and over 25,000 described species, along with six extinct genera known only from the fossil record. Species in the Agaricales range from the familiar ''Agaricus bisporus'' (cultivated mushroom) and the deadly ''Amanita virosa'' (destroying angel) to the coral-like ''Clavaria zollingeri'' (violet coral) and bracket-like ''Fistulina hepatica'' (beefsteak fungus).

Psilocybe Fuscofulva
''Psilocybe fuscofulva'' is a species of mushroom in that grows on ''Sphagnum'' moss and rarely decaying wood in peat bogs in North America and Europe. It, alongside ''Psilocybe fimetaria'', are the only species of ''Psilocybe'' that have been found with no psilocybin or psilocin content. The phylogenetic placement indicates its close relationship to '' Psilocybe silvatica'' and ''Psilocybe semilanceata''. It was previously most commonly known as ''Psilocybe atrobrunnea'' but the holotype does not exist and the neotype of this species was lost, so ''Psilocybe fuscofulva'', which was previously regarded as a synonym A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are a ... but has a holotype, was resurrected to replace it. It is considered inedible.

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.

Conserved Name
A conserved name or ''nomen conservandum'' (plural ''nomina conservanda'', abbreviated as ''nom. cons.'') is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. ''Nomen conservandum'' is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the International Code of Nomenclature for algae, fungi, and plants, ''International Code of Nomenclature for Algae, Fungi, and Plants'' (ICN), while the ''International Code of Zoological Nomenclature'' favours the term "''conserved name''". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed", ''nomen rejiciendum'' (plural ''nomina rejicienda'' or ''nomina utique rejicienda'', abbreviated as ''nom. rej.''), or rejected in favour of a particular conserved name, and combi ...

Phaeogalera
''Phaeogalera'' is a small genus of slender, fleshy bog and swamp-inhabiting mushrooms with large, brownish spores with a germ pore and a hymenium lacking chrysocystidia. ''Phaeogalera'' resemble ''Galerina'' in their habitat, macroscopic appearance, and spore print color, however, their microscopic characteristics (smooth spores with a distinct germ pore and non-tibiiform cystidia) more closely resemble ''Psilocybe''. The type species, ''Phaeogalera stagnina'', has an Arctic- alpine distribution in the Northern Hemisphere extending into the boreal forests and taiga. It grows along the edges of bogs in peaty soils and sometimes amongst ''Sphagnum'' or other mosses. This type species has been classified in ''Galerina'', '' Tubaria'' and ''Psilocybe''. Modern molecular evidence supports the recognition of ''Phaeogalera'' as an independent genus separate from ''Galerina''. The generic name is built upon the antiquated generic name "Galera", now synonymous A synonym is a word, mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuehneromyces
''Kuehneromyces'' is a genus of agaric fungi in the family Strophariaceae. The genus was circumscribed by mycologists Rolf Singer and Alexander H. Smith in 1946. The genus name of ''Kuehneromyces'' is in honour of Robert Kühner (1903-1996), who was a French mycologist most notable for reviewing many agaric. The best known species in the genus is '' K. mutabilis'', the sheathed woodtuft, which – despite closely resembling the deadly galerina,'' Galerina marginata'', – is a popular edible mushroom in Europe that can also be cultivated on wood. See also *List of Agaricales genera This is a list of fungal genus, genera in the order (biology), order Agaricales.

Deconica
''Deconica'' is a genus of mushroom-forming fungi in the family Strophariaceae. It was formerly considered synonym (taxonomy), synonymous with ''Psilocybe'' until molecular phylogenetics, molecular studies showed that genus to be polyphyletic, made of two major clades: one containing bluing, hallucinogenic species, the other non-bluing and non-hallucinogenic species. ''Deconica'' contains species formerly classified in the section (biology), sections ''Deconica'' and ''Coprophila'' of ''Psilocybe''. Taxonomy Until recently, ''Deconica'' was generally considered to be synonym (taxonomy), synonymous with ''Psilocybe'', and was originally named as a subgenus of ''Agaricus'' by Worthington George Smith in 1870. It was later raised to generic level by Petter Karsten in 1879. However, several molecular phylogenetics, molecular studies published in the 2000s demonstrated that ''Psilocybe'', as it was defined then, was polyphyletic. The studies supported the idea of dividing the genus int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galerina
''Galerina'' is a genus of small brown-spore saprobic mushroom-bearing fungi, with over 300 species found throughout the world from the far north to remote Macquarie Island in the Southern Ocean. The genus is most noted for some extremely poisonous species which are occasionally confused with hallucinogenic species of ''Psilocybe''. ''Galerina'' mushrooms are typically small and hygrophanous, with a slender and brittle stem. They are often found growing on wood, and when on the ground have a preference for mossy habitats. ''Galerina'' means ''helmet-like''. Taxonomic definition The genus ''Galerina'' is defined as small mushrooms of mycenoid stature, that is, roughly similar in form to ''Mycena'' species: a small conical to bell-shaped cap, and gills attached to a long and slender cartilaginous stem. Species have a pileipellis that is a cutis, and ornamented spores that are brown in deposit, where the spore ornamentation comes from an extra spore covering. Description ''Ga ...

Cladistics
Cladistics ( ; from Ancient Greek 'branch') is an approach to Taxonomy (biology), biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived (phylogenetics), derived characteristics (synapomorphies) that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose Phenotypic trait, character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used Paraphyly, paraphyletically, outside of cladistics, e.g. as a 'E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a phylogenetic tree#Rooted tree, rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, Phylogenetic diversity, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and cladogenesis, diversification. However, such a correlation does not make a given ca ...

Pileipellis
The pileipellis is the uppermost layer of hyphae in the pileus of a fungal fruit body. It covers the trama, the fleshy tissue of the fruit body. The pileipellis is more or less synonymous with the cuticle, but the cuticle generally describes this layer as a macroscopic feature, while pileipellis refers to this structure as a microscopic layer. Pileipellis type is an important character in the identification of fungi. Pileipellis types include the cutis, trichoderm, epithelium, and hymeniderm types. Types Cutis A cutis is a type of pileipellis characterized by hyphae that are repent, that is, that run parallel to the pileus surface. In an ixocutis, the hyphae are gelatinous. Trichoderm In a trichoderm, the outermost hyphae emerge roughly parallel, like hairs, perpendicular to the cap surface. The prefix "tricho-" comes from a Greek word for "hair". In an ixotrichodermium, the outermost hyphae are gelatinous. Epithelium An epithelium is a pileipellis consisting of rounded ce ...
