Nutcracker mushroom is a TAT mutation. In 2020, “Myco Clay” a Trusted Cultivator of the Shroomery.org, started isolating a mutation from a Yeti culture. Over 15 generations phenotypes showing extremely wrinkled caps, with severe bruising, ridges, bumps and wavy blue cap edges were isolated. This variant was dubbed “Nutcracker” in lieu of the originally conjured, less appealing name “Nutsack”. Nutcracker was released to the public on March 5th, 2021 via the Shroomery Facebook page, and retail sales followed on the Myco Market Facebook page. Quote: “I figured most people I knew wouldn’t be too keen on eating a Penis Envy, and a Nutsack. I noticed that the texture not only showed similarities to shrivelled up balls, but also showed similarities to the texture of walnuts, or pecans.”
