Yellow Umbo (Ps ochraceocentrata x Ps cubensis ‘Jack Frost’) is the first documented hybrid of Psilocybe Cubensis with another species! This was acheived by Yoshi via pairing of monokaryons of Ps cubensis and Ps ochraceocentrata that were gathered through serial streaking and some novel microscopy techniques developed with the help of Kilor Diamond. Each step of the process was verified using microscopy and also through interspecific verification testing done by Imperial Labs. This project is a momentous acheivement in home mycology.
