PES Amazonian Spores

PES Amazonian spores are some of the most sought-after psilocybe cubensis magic mushrooms because the spores are unlikely to become contaminated when placed on a slide. These spores are originally from a high-performing strain of Pacifica Exotica Spora. PES Amazonian is known for fruiting very large mushrooms in the wild, typically with a thick stem.

The strain was first discovered over 40 years ago. As the name suggests, PES Amazonian originates within the Amazonian rainforest. The long, thick stems—when at maturity in the wild—enable this mushroom to absorb nutrients and better distribute its spores.

The biodiversity of the Amazon rainforest helped enable this strain to become contaminant resistant. Since the spores are not likely to become contaminated when placed on a microscopic slide, this strain is considered a good choice for beginners in microscopy. It also performs well in cooler temperatures for year-round research.

PES Amazonian mushrooms produce spores that are dark purplish-brown. The dense fruits have a deep blue coloring upon cutting. The cap is in proportion to its thick stem and turns a caramel color at maturity.
