Not to be confused with the edible version of the same name "rugoso-annulata", this cubensis produces large, meaty fruits abundantly in the wild.
A pretty strain with good pin set and potency. Only drawback is a propensity to form hollow stems. Some of the most deformed mushrooms in the wild have come from this strain. Medium potency levels of psilocybe but a very good visual under the microscope.
