Apart from the psychedelic psilocybin, the metabolite spectrum of Psilocybe "magic mushrooms" comprises sesquiterpenes, a class of natural products known to exhibit receptor-modulating bioactivities. However, the composition of the sesquiterpene profile has largely remained an open question. Here, we report the characterization of five Psilocybe cubensis ses...
In April 2024, FSQ Forensic Chemists attended Queensland’s largest mushroom growing operation. Seized items included: 219 50 L plastic tubs of mushrooms in growth medium, bags of dried mushroom material, sterilised grain bags and spores in liquid. In consultation with QPS, six exhibits were selected for illicit drug analysis. Fresh mushrooms were harvested a...
The growing percentage of people suffering from drug-resistant depression increases interest in alternative therapies, particularly the usage of psychedelics such as psilocybin. The main source of psilocybin is the Psilocybe cubensis species. Due to the potential therapeutic benefits of psilocybin and the legal restrictions on its possession and use in the f...
Psilocybin, the psychoactive compound responsible for the hallucinogenic effects of “magic mushrooms,” is synthesized by a biosynthetic gene cluster (BGC) traditionally associated with Psilocybe species. However, psilocybin production has also been identified in multiple genera across the Strophariaceae, Hymenogastraceae, and Galeropsidaceae families. Here, ...
The resurgence of interest in the therapeutic potential of psilocybin-producing mushrooms has recently led to numerous research and commercialization efforts. Due to its ease of cultivation and high potency, Psilocybe is the primary genus of interest, and there is a growing need to standardize maintenance, proliferation, and cultivation techniques for effici...
Psilocybe "magic mushrooms" are best known for their indolethylamine psilocybin, yet they encode enzymes for a much more diverse arsenal of small and potentially bioactive molecules. Herein, four Psilocybe cubensis clade III sesquiterpene synthases, CubB-CubE, whose genes are differently expressed in fruiting bodies compared to vegetative mycelium are report...
BACKGROUND: Psilocybin-containing mushrooms are gaining the attention of the scientific community due to the potential benefits offered by their psychoactive phytochemicals in the treatment of addiction and various mental health conditions. Although there are hundreds of different Psilocybe species, only a handful have been successfully cultivated under indo...
Psilocybe cubensis, a widely recognized psychoactive mushroom species, has played a significant role in both historical and modern therapeutic practices. This review explores the complex interplay between genetic diversity, strain variability and environmental factors that shape the biosynthesis of key psychoactive compounds, including psilocybin and psiloci...
BACKGROUND: Although Basidiomycota produce pharmaceutically and ecologically relevant natural products, knowledge of how they coordinate their primary and secondary metabolism is virtually non-existent. Upon transition from vegetative mycelium to carpophore formation, mushrooms of the genus Psilocybe use L-tryptophan to supply the biosynthesis of the psyched...
Psilocybe mushrooms, otherwise known as “magic” mushrooms, owe their psychedelic effect to psilocin, a serotonin subtype 2A (5-HT2A ) receptor agonist and metabolite of psilocybin, the primary indole alkaloid found in Psilocybe species. Metabolomics is an advanced fingerprinting tool that can be utilized to identify the differences among fungal life stages t...
Psilocybin, psilocin, baeocystin, norbaeocystin, and aeruginascin are tryptamines structurally similar to the neurotransmitter serotonin. Psilocybin and its pharmacologically active metabolite psilocin in particular are known for their psychoactive effects. These substances typically occur in most species of the genus Psilocybe (Fungi, Strophariaceae). Even ...
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...
Paul Stamets, founder and director of Fungi Perfecti, LLC., and director of the Fungi Perfecti Research Laboratories (www.fungi.com), has been a mycologist and mushroom enthusiast for more than 30 years. A pioneer in the cultivation of edible and medicinal mushrooms, he is credited with the discovery of four new mushroom species. Stamets is the author of fiv...
The Panaeolus bisporus(Malen con & Bertault) Ew.Gerhardt is a toadstool species in the world,as poisonous as it contains small quantities of the psilocybin group of hallucinogens,mycelium is white with obvious clamp-connection,which belongs to Basidiomycota,Agaricales,Bolbitiaceae.The suitable and optimal carbon sources,nitrogen sources,carbon nitrogen ratio...
The following questions regarding the detection of psychoactive drugs in mushrooms are addressed: At what stage of the mushroom development can the psychoactive drugs psilocyn and psilocybin be identified, and what effect does light have on the growth of these mushrooms. To answer these questions, Psilocybe cyanescens Wakefield mushrooms were grown from thei...
Several specimens of Psilocybe and Copelandia species in Koh Samui, Thailand were recently collected for herbarium deposit and scientific study. This paper presents an ethnomycological and biochemical study of one of the species; P. samuiensis Guzmán, Bandala and Allen, a new psychoactive gill fungus reported from Thailand. Mycelium for the cultivation of P....
Abstract The psychotropically active principles of the Mexican hallucinogenic fungus Psilocybe maxicana H EIM have been isolated and obtained in crystalline form. The two new substances, which have been called psilocybin and psilocin, are present in the fruit bodies, the artificially cultivated mycelium and in the sclerotia. The dried mushroom contains 0.2 t...
