DESCRIPTION
Psilocybe cubensis Puerto Rico Spores
Psilocybe cubensis “Puerto Rico” is a legendary strain discovered on the lush, humid island of Puerto Rico in the late 1990s. First isolated by enthusiasts fascinated with tropical genetics, this variety quickly became popular for its robust and resilient spores.
Scientific Characteristics:
-
Spore Color: Rich, dark purple-brown, a hallmark of the P. cubensis species.
-
Shape & Size: Spores are typically elliptical, measuring about 12–16 x 8–11 micrometers, with a smooth surface under the microscope.
-
Appearance: Puerto Rico spores are easily recognized by their dense pigment and uniform shape, offering clear definition under magnification.
-
Mycelium Traits: Known for aggressive, fast-spreading mycelium—often cited in scientific circles for its resilience in variable climates.
-
Fruit Body Notes: In natural habitats, mature specimens feature wide, caramel caps and thick, robust stems—though research here is strictly spore-focused.
Research Use:
Highly favored among mycologists and microscopy hobbyists, Puerto Rico spores are ideal for those interested in studying tropical cubensis adaptations. Their strong genetic stability makes them a go-to for comparative spore research.
