The fungal genus Psilocybe and other genera comprise numerous mushroom species that biosynthesize psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine). It represents the prodrug to its dephosphorylated psychotropic analogue, psilocin. The colloquial term "magic mushrooms" for these fungi alludes to their hallucinogenic effects and to their use as recreational...
In nature, there are >200 species of fungi with hallucinogenic properties. These fungi are classified as Psilocybe, Gymnopilus, and Panaeolus which contain active principles with hallucinogenic properties such as ibotenic acid, psilocybin, psilocin, or baeocystin. In Chile, fungi seizures are mainly of mature specimens or spores. However, clandestine laborat...
Entomopathogenic fungi routinely kill their hosts before releasing infectious spores, but select species keep insects alive while sporulating, which enhances dispersal. Transcriptomics and metabolomics studies of entomopathogens with post-mortem dissemination from their parasitized hosts have unraveled infection processes and host responses, yet mechanisms u...
Heterologous expression of multi-gene biosynthetic pathways in eukaryotic hosts is limited by highly regulated individual monocistrons. Dissimilar to prokaryotes, each eukaryotic gene is strictly controlled by its own regulatory elements, such as promoter and terminator. Consequently, parallel transcription can occur only when a group of genes is synchronous...
Secondary metabolites are a heterogeneous class of chemicals that often mediate interactions between species. The tryptophan-derived secondary metabolite, psilocin, is a serotonin receptor agonist that induces altered states of consciousness. A phylogenetically disjunct group of mushroom-forming fungi in the Agaricales produce the psilocin prodrug, psilocybi...
Psilocybin mushrooms, commonly known as magic mushrooms or shrooms, are a polyphyletic, informal group of fungi that contain psilocybin which turns into psilocin.[1][2] Biological genera containing psilocybin mushrooms include Copelandia, Gymnopilus, Inocybe, Panaeolus, Pholiotina, Pluteus, and Psilocybe. Psilocybin mushrooms have been and continue to be use...
The euphoria and hallucinations induced from eating Psilocybe “magic mushrooms” have earned the fungi a cult following. Albert Hofmann, a chemist at Sandoz, isolated and determined the structure of psilocybin, the main ingredient in the mushrooms that leads to the psychedelic effects, nearly 60 years ago. That discovery and subsequent mind-altering experimen...
Secondary metabolites are heterogeneous natural products that often mediate interactions between species.

Mushrooms are probably the best known fungi and usually found springing up on dead wood after cool, wet weather; the mushroom is a common sight. Psilocybin mushrooms, also known as psychedelic mushrooms, are mushrooms that contain the psychedelic compounds psilocybin and psilocin. It is used mainly as an antigen and recreational drug whose effects can includ...
Substances of plant origin have been used to induce hallucinations for a long time, in religious ceremonies and rituals as well as in pain relief. Psilocybin and psilocin naturally occur in the fungal genus Psilocybe. Due to the psychedelic effects and relative harmlessness of these substances and the fact that they do not cause physical addiction, psilocybi...
Light microscopical examination of plant and fungal remains in the post mortem gut may be capable of demonstrating the ingestion of unexpected natural psychotropic materials. This is demonstrated here in a case in which a 'shaman' was accused of causing the death of a young man. The deceased had participated in a ceremony which involved the drinking of ayahu...
Five Psilocybe species with unresolved systematic position (P. atrobrunnea, P. laetissima, P. medullosa, P. pelliculosa, and P. silvatica) were investigated using four molecular markers (EF1-α, ITS, LSU, and IGS). Phylogenetic analysis revealed that with the exception of P. laetissima, which is now rightfully classified in the genus Leratiomyces, all investi...
Mushroom-forming fungi produce a wide array of toxic alkaloids. However, evolutionary analyses aimed at exploring the evolution of muscarine, a toxin that stimulates the parasympathetic nervous system, and psilocybin, a hallucinogen, have never been performed. The known taxonomic distribution of muscarine within the Inocybaceae is limited, based only on assa...
"Magic mushrooms" is the most common name given to hallucinogenic fungi containing the psychoactive alkaloids psilocybin and psilocin. In recent years, fungis' sclerotia, commonly called "magic truffles" have become a form of supply of psychoactive Psilocybe alkaloids since Psilocybe sclerotia are not specifically included in the laws banning the sale, the p...
Psilocybin adalah jenis NAPZA golongan psikotropika, bersifat halusinogenik dan terdapat pada spesies jamur-jamuran. Nama lain yang sering digunakan adalah magic mushroomdan tai kebo. Saat ini halusinogen berada di posisi ketiga zat yang paling banyak disalahgunakan, dengan peningkatan angka penggunaan dari Psilocybin. Penelitian ini bertujuan mengetahui kar...
IntroductionThe American continent is very rich in psychoactive plants and fungi, and many pre-Columbian Mesoamerican cultures used them for magical, therapeutic and religious purposes.ObjectivesThe archaeological, ethno-historical and ethnographic evidence of the use of hallucinogenic substances in Mesoamerica is reviewed.ResultsHallucinogenic cactus, plant...
Hallucinogenic mushrooms (e.g. Psilocybe and Panaeolus species) as well as leaves and young shoots of the khat tree (Catha edulis Forsk) are illicit drugs in many countries. The exact concentration of the hallucinogenic alkaloids psilocin and psilocybin in mushrooms and the sympathomimetic alkaloids cathinone and cathine in khat is usually essential for juri...
I. Psilocybe cubensis was cultured successfully in two media. Medium A was devised by Catalfomo and Tyler and Medium B was a modification of a medium which has been used for ergot alkaloid production by Claviceps purpurea. Only when the fungus was kept on Sabouraud agar plates.did it subsequently produce psilocybin when transferred to liquid media. A quantit...
Two topics, related to mushroom poisoning of recent interest in Japan, have been presented. In autumn 2004, 59 cases of acute encephalopathy were reported across 9 prefectures in Japan (24 from Akita Prefecture with 8 deaths; age 48-93, average 70; female 14, male 10). Of 24 cases, 20 had kidney dysfunction. Four poisoned subjects showed no kidney trouble. O...
