Jack Frost × Yellow Umbo

A hybrid Psilocybe cubensis strain combining the frosty, ghost-white appearance and heavy sporulation of Jack Frost with the distinctive genetics of Yellow Umbo. Produces medium to large fruits with thick white stems, pale to icy-white caps that may develop blue bruising, and occasional yellowish or cream undertones inherited from the Yellow Umbo lineage. Expected to exhibit vigorous colonization, dense flushes, and strong visual appeal. Phenotypes may vary, displaying combinations of leucistic coloration, unique cap morphology, and robust growth characteristics due to hybrid genetic segregation.
