Some reports suggest this strain was created by the legendary mycologist Paul Stamets, but he’s never publicly accepted credit for this unique mushroom.
There’s another story about the origin of Z Strain Spores in that a mysterious mycologist named “The Keeper,” who claims to be responsible for cultivating this strain. The controversy is that The Keeper would take established mushroom strains, rename them, and sell them online as their invented strain through ad.
According to a Reddit thread, The Keeper was caught when they used photos of established strains and forgot to change the names of the files when uploading them online under their new strain name.
