Under the microscope
Under the microscope, Psilocybe cubensis spores are dark purple-brown, subellipsoid to ellipsoid, roughly 11.5 to 17 microns long by 8 to 11 microns wide, each with a distinct broad germ pore. Spore morphology is consistent across cubensis varieties, so strains are distinguished by provenance and the phenotype of the fruit body rather than by the spores alone. The spores themselves contain no psilocybin, which is why they are legal to study for microscopy and research in most U.S. states.
