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] |
Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. He is sometimes called the Mycology, "Linnaeus of Mycology". In his works he described and assigned botanical names to hundreds of fungus and lichen species, many of which remain authoritative today. 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 studied under Carl Adolph Agardh and Anders Jahan Retzius. He obtained his doctorate in 1814. In the same year he was appointed an associate professorship in botany. Fries edited several exsiccata series, the first starting in 1818 under the title ''Lichenes Sveciae exsiccati, curante Elia Fries'' and the last together with Franz Joseph Lagger under the title ''Hieracia europaea exsiccata''. He was elected a member of the Royal Swedish Academ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psilocybe Cubensis
''Psilocybe cubensis'', commonly known as the magic mushroom, shroom, golden halo, golden teacher, cube, or gold cap, is a species of psilocybin mushroom of moderate potency whose principal Psychoactive compound, active compounds are psilocybin and psilocin. It belongs to the fungus family Hymenogastraceae and was previously known as ''Stropharia cubensis''. It is the best-known psilocybin mushroom due to its wide distribution and ease of cultivation. Taxonomy The species was species description, first described in 1906 as ''Stropharia cubensis'' by American mycologist Franklin Sumner Earle in Cuba. In 1907, it was identified as ''Naematoloma caerulescens'' in Tonkin (French protectorate), Tonkin (now Vietnam) by French pharmacist and mycologist Narcisse Théophile Patouillard, while in 1941, it was called ''Stropharia cyanescens'' by William Alphonso Murrill near Gainesville, Florida, Gainesville in Florida. German-born mycologist Rolf Singer moved the species into the genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in ) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'', is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. Definitions The term is defined in different ways by different authors. However, the International Code of Nomenclature for Cultivated Plants, while recognizing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxon
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MycoBank
MycoBank is an online database, documenting new mycological names and combinations, eventually combined with descriptions and illustrations. It is run by the Westerdijk Fungal Biodiversity Institute in Utrecht. Each novelty, after being screened by nomenclatural experts and found in accordance with the ICN (International Code of Nomenclature for algae, fungi, and plants), is allocated a unique MycoBank number before the new name has been validly published. This number then can be cited by the naming author in the publication where the new name is being introduced. Only then, this unique number becomes public in the database. By doing so, this system can help solve the problem of knowing which names have been validly published and in which year. MycoBank is linked to other important mycological databases such as Index Fungorum, Life Science Identifiers, Global Biodiversity Information Facility (GBIF) and other databases. MycoBank is one of three nomenclatural repositories reco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (biology)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called '' Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, 17 ...

Psilocybe
''Psilocybe'' ( ) is a genus of gilled mushrooms, growing worldwide, in the family Hymenogastraceae. Many species contain the Psychedelic drug, 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 mushroom, hallucinogenic species constituted one clade and the non-bluing species the other. The previous Type (biology), type species of the genus, ''Psilocybe '' (now ''Deconica montana''), was in the non-bluing clade, but in 2010, the type species was changed to ''Psilocybe semilanceata, 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, strongl ...

Paul Kummer
Paul Kummer (22 August 1834 – 6 December 1912) was a Minister (Christianity), minister, teacher, and scientist in Zerbst, Germany, known chiefly for his contribution to mycological botanical nomenclature, nomenclature. Earlier Taxonomy (biology), classification of agarics by pioneering fungal taxonomist Elias Magnus Fries designated only a very small number of genus, genera, with most species falling into ''Agaricus''. These few genera were divided into many ''tribus'' ("tribes"; not Tribe (biology), tribes in the modern sense). In his 1871 work, ''Der Führer in die Pilzkunde'', Kummer raised the majority of Fries ''"tribus"'' to the status of genus, thereby establishing many of the generic names for agarics that are in use to this day. In 1874 he issued the work ''Der Führer in die Flechtenkunde'' with numbered lichen specimens arranged in two plates like an exsiccata. From 1857 to 1863, he worked as a private lecturer, then served as a curate in Zerbst (1863–1877). [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phrygian Cap
The Phrygian cap ( ), also known as Thracian cap and liberty cap, is a soft Pointed hat, conical Hat, cap with the apex bent over, associated in Classical antiquity, antiquity with several peoples in Eastern Europe, Anatolia, and Asia. The Phrygian cap was worn by Thracians, Dacians, Persians, Medes, Scythians, Troy, Trojans, and Phrygians after whom it is named. The oldest known depiction of the Phrygian cap is from Persepolis in Iran. Although Phrygian caps did not originally function as liberty caps, they came to signify freedom and the pursuit of liberty first in the American Revolution and then in the French Revolution, particularly as a symbol of Jacobinism (in which context it has been also called a Jacobin cap). The original cap of liberty was the Roman ''Pileus (hat), pileus'', the felt cap of emancipated slaves of ancient Rome, which was an attribute of Libertas, the Roman goddess of liberty. In the 16th century, the Roman iconography of liberty was revived in emblem b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legal Status Of Psilocybin Mushrooms
The legal status of unauthorised actions with psilocybin mushrooms varies worldwide. Psilocybin and psilocin are listed as Schedule I drugs under the United Nations 1971 Convention on Psychotropic Substances. Schedule I drugs are defined as drugs with a high potential for abuse or drugs that have no recognized medical uses. However, psilocybin mushrooms have had numerous medicinal and religious uses in dozens of cultures throughout history and have a significantly lower potential for abuse than other Schedule I drugs. Psilocybin ''mushrooms'' are not regulated by UN treaties. Many countries, however, have some level of regulation or prohibition of psilocybin mushrooms (for example, the US Psychotropic Substances Act, the UK Misuse of Drugs Act 1971, and the Canadian Controlled Drugs and Substances Act). In some jurisdictions, ''Psilocybe'' spores are legal to sell and possess, because they contain neither psilocybin nor psilocin. In other jurisdictions, they are banned be ...
