Quick answer: Jedi Mind Fuck (JMF) is a named strain of Psilocybe cubensis whose origin has never been documented. A popular story says a grower known as “Myco Joe” bred it from wild cubensis in Georgia in the early 2000s, and another account calls it a cross of Z-Strain and Golden Teacher made around 2014. DoubleBlind Magazine reports that neither story has been confirmed. The Star Wars name is the only part everyone agrees on. It is recognizable by a large golden-brown cap with a pronounced central bump and a thick stem, and in 2025 it became the first named cubensis strain used in an FDA-cleared U.S. clinical trial of whole mushrooms.
Spores are legal to buy for microscopy in 46 states. Germinating them is not, which is why nothing on this page is about cultivation.

What Jedi Mind Fuck is
Jedi Mind Fuck, usually shortened to JMF (and sometimes euphemized as “Jedi Mind Trick” on storefronts that avoid the word), is a strain of Psilocybe cubensis. Like every named cubensis strain, it is the same species as Golden Teacher, B+ or Penis Envy; the name marks a line hobbyists have kept separate because of its consistent look. There is no official registry of strains, and a 2023 Current Biology study found that cultivated cubensis lines descend from very few founders, so the genetic distance between JMF and its neighbors is small. What makes JMF worth a name is its phenotype: big, golden-brown, umbonate caps on thick stems.
History and origin: competing stories
JMF’s history comes from online forums, and the stories no longer agree.
- The Georgia story. Third Wave and Psychedelic Spotlight both repeat a popular story that a grower posting as “Myco Joe” (also called “Agar Joe”) found wild cubensis in Georgia, the U.S. state, and bred JMF from it. Third Wave dates this to the early 2000s. Both sites call it a story, not a documented fact.
- The hybrid story. A second account, published by a spore vendor, says JMF was an intentional cross of Z-Strain and Golden Teacher made around 2014, and names “Myco Joe” and a collaborator known as “John Meddler” as its makers.
- The Instagram account. DoubleBlind Magazine reports that credit often goes to the Instagram grower “Agar Joe” or “Myco Joe,” but its sources could not confirm he created the strain. Other posts name the Instagram user MrMyco instead.
The accounts disagree on the date and on how the strain was made, and no prints, dates or first-hand posts have surfaced to settle it. DoubleBlind Magazine says the strain has grown in popularity mainly in the last few years, through mushroom groups on Reddit and Instagram.
The name
The Star Wars reference is deliberate and dates from the strain’s release. Beyond that there is no documented story about who chose it or why, and the folklore explanations (“it does something to your mind”) are exactly the kind of claim a spore vendor cannot make and we will not repeat. Storefronts that sell to a general audience sometimes list it as “Jedi Mind Trick” or “JMF” for the same reason.
JMF in the Arizona clinical trial
JMF has one distinction no other named strain can claim. In 2025 the Scottsdale Research Institute, a nonprofit psychedelics research lab in Arizona led by Dr. Sue Sisley, received FDA clearance for the first U.S. clinical trial to study whole psilocybin mushrooms, rather than synthetic psilocybin, for post-traumatic stress disorder in veterans, police officers and firefighters. The trial is funded through $5 million that the Arizona Legislature set aside in its 2023 budget (SB 1720). A companion 2023 law, SB 1726, set up the grant program and a Psilocybin Research Advisory Council under the state health department. The strain the institute chose to cultivate under its DEA registration was Jedi Mind Fuck. Sisley told a conference audience she picked it partly because she enjoyed writing the name on government forms, and later said the choice had proved practical for the lab.
The trial does not change the legal status of the mushrooms (psilocybin remains Schedule I in Arizona and federally) or of the spores (already legal for microscopy in Arizona). It does mean that JMF is now the one hobbyist strain with a name in an FDA-cleared protocol.
What the mushroom looks like
- Cap: rich golden-brown to caramel, often lighter toward the margin. Hemispherical to convex when young, flattening with age, and notable for a pronounced umbo, the cone-shaped bump at the center, which becomes more obvious as the cap flattens and the edges turn upward. JMF caps run larger than average for the species.
- Gills: attached to the stem, closely spaced, whitish-gray when young and deep purple-brown at maturity.
- Stem: thick and solid-looking, white to pale yellow, commonly 5–15 cm tall, with a ring that collects a dark spore deposit. Handled areas bruise blue, most visibly at the base, a trait shared across the species.
- Spore print: dark purple-brown.
What JMF spores look like
At 400× JMF spores are the standard cubensis picture: smooth, thick-walled subellipsoid spores with a visible germ pore, purple-brown individually and near black in mass, in the species range of roughly 11–17 by 7–12 micrometers.
As with every pigmented cubensis strain, JMF spores are not distinguishable from Golden Teacher or B+ spores by light microscopy.
Related strains
- Golden Teacher and Z-Strain are the claimed parents in the hybrid account. Both are older, widely distributed lines; see our Golden Teacher guide.
- Albino JMF is a pale line offered by some vendors under the JMF name; documentation is thin.
- Isolated JMF syringes are spores collected from a single selected JMF genetic line rather than from an ordinary print; they are still spores, not a culture. Our spore syringe guide explains the difference.
Legal status of JMF spores
JMF spores contain no psilocybin or psilocin, so under federal law and the law of 46 states they are not a controlled substance; the DEA confirmed the federal position in writing in January 2024. California and Florida restrict spores, Georgia and Idaho ban them, and we do not ship Psilocybe spores to those four states. Germinating spores is illegal under federal law everywhere. Our state-by-state legal guide has every statute.
Frequently asked questions
What is the Jedi Mind Fuck mushroom?
A named strain of Psilocybe cubensis from the U.S. hobbyist scene, recognizable by large golden-brown caps with a central bump and thick stems.
What is the JMF strain’s scientific name?
Psilocybe cubensis. “Jedi Mind Fuck” is an informal strain name, not a taxonomic one.
Where did Jedi Mind Fuck come from?
No one has documented it. A popular story says a grower known as “Myco Joe” bred it from wild cubensis in Georgia in the early 2000s. Another account calls it a Z-Strain × Golden Teacher cross made around 2014 by “Myco Joe” and “John Meddler.” DoubleBlind Magazine reports that neither story has been confirmed.
Is Jedi Mind Fuck the same as Jedi Mind Trick?
Yes. “Jedi Mind Trick” and “JMF” are polite listings of the same strain.
Why is JMF in the news?
Because the Scottsdale Research Institute chose it for the first FDA-cleared U.S. clinical trial of whole psilocybin mushrooms, funded by the State of Arizona. The trial concerns the mushrooms, grown under a DEA registration; it does not change the law for anyone else.
What do JMF spores look like under a microscope?
Smooth, thick-walled, purple-brown ovals with a germ pore, about 11–17 by 7–12 micrometers, indistinguishable from other pigmented cubensis strains by light microscopy.
Are Jedi Mind Fuck spores legal?
Yes, for microscopy, in 46 states. Not in California, Florida, Georgia or Idaho, where we do not ship.
Do you sell JMF spores?
Yes: a lab-prepared Jedi Mind Fuck spore syringe (a 10 cc syringe) with a sterile needle and a 30-day guarantee, for microscopy and taxonomy use only. You can see all of our strains on our spore syringes page.
