Strain Origin

Not too much is known about this strain’s true beginnings, other than that it was not found naturally occurring. Rather, this strain was created in a lab-setting with the intention of producing an easy & quickly colonizing cubensis. The mycologist named “The Keeper” succeeded at this task, and now the strain is one of the more popular on earth! If you’re a beginner or simply want something vigorous to study, consider the Z-Strain today.


Z-Strain is a very easy strain to work with. For context, it is likely similar to difficulty of B+, which is considered one of the easiest as well.

Spore Features

Spores are dark purple to brownish, sub-ellipsoid on 4-spored basidia. This strain produces a lot of research material, which makes it great for microscopy.


Z-Strain spores are not rare. However, finding ones that are viable, sterile, and genetically proven is much rarer than you’d think. Many companies provide mixed bags, impure genetics, or worst of all, a completely different species! Nonetheless, this strain is relatively unique and should make a cool addition to any collection.

Cultural Significance 

Z-Strain is quite enigmatic in this sense, in that its effect on mainstream culture & mycology is rather unknown. Unlike Golden Teacher which has sparked a movement, the Z-strain mushroom flies a bit more under the radar.
