The mushroom flesh is thick at first – rich in psilocybin et alia. “Psilocybe cubensis mycelium makes mushrooms which have lots of psilocybin, psilocin, and other analogs. Psychedelic Science Review reached out to Stamets for further insight on the state of the art in psilocybin and spores. Therefore, the statement is suggesting that somewhere along the way between gills and spore formation, psilocybin stops going along for the ride. cubensis, Stamets said (34:46), “… spores contain no psilocybin, the flesh of the mushroom transmutates into gills into spores.” 3 While discussing potential commercial growing operations of P. In June 2021, psychedelic mushroom expert Paul Stamets was a guest at the Oregon Department of Human Services Psilocybin Advisory Board Product Subcommittee Meeting. Why is there no psilocybin in the spores? When in Doubt, Ask Paul Stamets This presents an interesting question for mycologists to take on. The production of psilocybin-containing mycelium (and the subsequent mushroom fruiting) is a violation of the law in many jurisdictions. It’s a different story when a person introduces the spores into a favorable environment and mycelium starts growing. Hence, the spores are available for purchase but only for microscopy studies. cubensis (and other psilocybin-containing mushrooms) don’t contain psilocybin. It is also well known in the psychedelic mushroom cultivation community and law enforcement that the spores of P. Interestingly, the mycelium of many psilocybin mushrooms such as Psilocybe cubensis also bruises blue, indicating the presence of psilocybin. 1 Historically, expert mycologists like Paul Stamets have relied on bluing as one criterion for identifying psilocybin-containing mushrooms in addition to a purple-brown spore print. Claudius Lenz discovered the chemical mechanism behind the transformation of psilocybin molecules into blue compounds. Psilocybin mushrooms (aka magic mushrooms) have a long-standing reputation for turning blue when bruised or undergoing environmental stress. Bauer, MS Psilocybe cubensis spore print.
No one knows, creating an opportunity for further understanding of single psychedelic compounds in the natural world. Amyloid basidiospores of Mycena crocea.Mushrooms Why Don’t Magic Mushroom Spores Contain Psilocybin? Photo credit: Davis Upchurch, UNC Undergrad and Herbarium Volunteer Figure 5. Mycena crocea Maas Geesteranus fruiting on a tree nut. In addition to its ecology, the amyloidity of its spores is a key feature in identification of M. If one finds this little guy, one can be certain to be in the presence of mature nut bearing trees (walnut, hickory). In image to the right, spore treated with iodine in the form of Melzers Regent have turned bluish-black.Ĭoker, famous UNC Botanist for whom Coker Hall is named, described this Amanita over 100 years ago in 1917.Ī current Herbarium project is inventorying the fungi of the North Carolina Botanical Garden which leads us to a neat mushroom that fruited in abundance this fall along the Meeting of the Waters Creek in the North Carolina Botanical Garden Meet Mycena crocea (Figure 4), a cute little agaric that shows what good plant taxonomists fungi are. Curiously, the flesh of this mushroom smells like raw potato, a second biochemical ‘connection’ to potatoes. Its lavender shades only develop when night temperatures are near freezing. This species is an ectomycorrhizal partner with pines. Fruiting locally in abundance this past October was Amanita lavendula, a Coker species, which is a member of the camp with amyloid spores (Figures 2 and 3). For example, the Amanita mushrooms fall into two camps: some have amyloid spores and some do not. In identifying mushrooms, having a black and white trait like amyloidity is a relief compared to traits that are grey and difficult to interpret. Sometimes only the ornamentation of the mushroom spores will show this amyloid reaction this is true for the milk mushrooms ( Lactarius) (Figure 1.) Figure 2.
The term for this reaction is amyloidity. One of the fun tricks is treating white mushroom spores with iodine in the form of Melzers Reagent to see if they turn bluish-black (much as iodine will turn the inside of potatoes bluish-black). Mushroom identification relies on many tricks of the trade. Amyloid ornamentation of Lactarius basidiospores.
