It’s origin is unknow but the name is definitely a tribute to honor the psychonaut Terence McKenna. The Mckennaii Magic mushroom grows it’s mushrooms in different sizes and cap shapes changes unlike any other cubensis.
The Mckennaii magic mushroom strain is probably named after Tercence McKenna. Although there are rumors that it’s not. The thing is that Terence didn’t come up with this strain. Some mycologist in The Netherlands might have given this (hybrid) cubensis strain the name McKennaii.
Most people see this as a tribute to the Master Psychonaut himself. But some see it as just a marketing trick. In the years past the Mckennaii Magic Mushroom proofed to be a different cubensis variation. Loved by a lot of it’s users for it’s strong trip and as a fast grower in a mushroom grow kit.
