Psilocybe Cubensis Variation: PES Amazonian (PESA)
Habitat: Bovine, Equine Dung and Enriched Soils
Cap: 25-50+ mm in diameter, convex to broadly convex to plane at maturity often with persistent acute umbo (nipple). Reddish cinnamon brown maturing to golden brown to light yellow with nearly white edges. Surface dry lacking remnants of universal veil on cap (spots). Flesh white soon bruising bluish green.
Stem: 150+ mm in length, yellowish. Flesh bruising bluish green where injured. Persistent membranous annulus (ring) from partial veil that becomes dusted with purple brown spores at maturity.
Gills: Attachment adnate to adnexed. Grayish coloration in young fruit bodies becoming nearly black in maturity.
Spores: Dark purplish brown, subellipsoid on 4-spored basidia
Strain Origin: While it probably did come from the Colombian Amazon, Pacifica Exotica Spora, the company which first sold it was known to name cubes after locations even if the spores did not originate from said location (See PES Hawaiian). Still, the Amazon is quite large, and PESA likely originated from that region.
According to Workman, PESA resembles B+ Type 2, the cube which was accidentally sold by Sporeworks as B+ for a few years before the error was discovered and remedied. For a time, there were many reports of B+ with hollow stems.
