Blue Umbo is the Albino branch of the yellow umbo hybrid project! This is early in stabilization so there's no telling what you might observe.
Yellow Umbo (Ps ochraceocentrata x Ps cubensis 'Jack Frost') is the first documented hybrid of P.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.
We are transitioning with the recent taxonomic change to the name of .aff natalensis. All products on the site will be renamed to Ps. ochraceocentrata immediately, but the physical products will still have .aff nat labeling until we can catch up. Thanks for your understanding and support!!
