Rhodocollybia Maculata
''Rhodocollybia maculata'', commonly known as the spotted toughshank, is a species of Basidiomycota#:~:text=Basidiomycota are filamentous fungi composed,specialized spores are called basidiospores., basidiomycete fungus in the family Omphalotaceae. It often appears in decomposing conifer duff. ''R. maculata'' is a source of collybolide, a sesquiterpenoid containing a furyl-ẟ-lactone motif reminiscent of salvinorin A. Description The cap is cream-colored with red-brown spots. The edge remains inrolled for an extended period of time. The whitish gills are crowded, becoming spotted in age. The similarly colored stipe is long, tough, hollow, and tapered downwards. A variety known as ''scorzonerea'' is characterized by yellowish color of its gills, and sometimes the stipe. Edibility Though non-toxic, this species is considered inedible due to its toughness and unpalatability; it is typically bitter. Kappa-opioid receptor agonism In 2016, Gupta ''et al.'' reported that collybo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omphalotaceae
The Marasmiaceae are a family of basidiomycete fungi which have white spores. They mostly have tough stems and the capability of shrivelling up during a dry period and later recovering. The widely consumed edible fungus ''Lentinula edodes'', the shiitake mushroom, is a member of this family. According to a 2008 estimate, the family contains 54 genera and 1590 species. The family Omphalotaceae, described by A. Bresinsky in 1985 as a segregate from the Tricholomataceae, has been considered synonymous with Marasmiaceae. However DNA analyses by Moncalvo et al. in 2002 and Matheny et al. in 2006 have now led to that family being accepted by Index Fungorum and most recent references. The following genera are included in that family : ''Anthracophyllum'', ''Gymnopus'', ''Lentinula'', ''Marasmiellus'', '' Mycetinis'', '' Rhodocollybia'', ''Omphalotus''.

Collybolide
Collybolide is a chemical constituent of the ''Rhodocollybia maculata'' mushroom, a fungus that grows on rotting conifer wood. It is potentially a potent and selective K-opioid receptor agonist, like salvinorin A. No total syntheses of this compound have been reported, and research is inconclusive as to whether collybolide is a K-opioid receptor agonist, and it still remains unknown whether collybolide is a hallucinogen; however, anecdotal reports suggest it is possible. If it is active in humans, collybolide will be the only non-salvinorin selective K-opioid receptor agonist psychedelic. Research Gupta ''et al.'' found collybolide to exhibit biased K-opioid agonist activity. K-opioid receptor agonists are under research for their potential in addiction treatment: and along with an easily modifiable structure (in contrast to salvinorin A), collybolide has attracted attention for the development of next-generation K-opioid receptor agonist analgesics, antipruritics, and antidep ...

Salvinorin A
Salvinorin A is the main active psychotropic molecule in '' Salvia divinorum''. Salvinorin A is considered a dissociative hallucinogen. It is structurally distinct from other naturally occurring hallucinogens (such as DMT, psilocybin, and mescaline) because it contains no nitrogen atoms; hence, it is not an alkaloid (and cannot be rendered as a salt), but rather is a terpenoid. It also differs in subjective experience, compared to other hallucinogens, and has been described as dissociative. Salvinorin A can produce psychoactive experiences in humans with a typical duration of action being several minutes to an hour or so, depending on the method of ingestion. Salvinorin A is found with several other structurally related salvinorins. Salvinorin is a ''trans''-neoclerodane diterpenoid. It acts as a kappa opioid receptor agonist and is the first known compound acting on this receptor that is not an alkaloid. History Salvinorin A was first described and named in 1982 ...

Fungi Of North America
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhodocollybia
''Rhodocollybia'' is a genus of Basidiomycete mushroom. Species in this genus, formerly classified as a subgenus in ''Collybia'', have fairly large caps (typically larger than broad), and have a pinkish-tinted spore print. Microscopically, they are characterized by having spores and basidia that are dextrinoid—staining deep reddish to reddish-brown with Melzer's reagent when tested for amyloidity. ''Rhodocollybia'' species are commonly found in temperate North America and Europe, and infrequently in Central and South America. Taxonomy The genus name ''Rhodocollybia'' was first used by Rolf Singer in 1939 to describe those species of ''Collybia'' with a pink spore deposit; in later works he considered the genera equivalent (synonymous) and called them ''Collybia''. In 1997, Antonín and Noordeloos studied various members of ''Collybia'' using phylogenetic analysis, and reorganized the genus, dividing species into either ''Collybia'', ''Gymnopus'', or ''Rhodocollybia''.

Taxa Named By Johannes Baptista Von Albertini
In biology, a taxon (back-formation from ''taxonomy''; plural 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. 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 set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
