Psilocybe Cubensis Variation: B+ (“Be Positive”)

10ml Spore Syringe

Habitat: Bovine, Equine Dung and Enriched Soils

Climate: Subtropical

Cap: 25-75 mm in diameter, hemispheric to convex expanding to broadly convex to nearly plane with age. Dark red maturing to golden brown. Surface viscid with apparent gelatinous layer when very wet, soon smooth from drying. Fine fibrillose veil remnants when young that soon disappear. Flesh white soon bruises bluish green.

 Stem: 150-200+ mm in length. Typically equal, sometimes slightly enlarged at base, sometimes contorted. Yellowish to buff with a reflective sheen, bruising bluish, hollow. Partial veil membranous leaving a persistent membranous annulus that is well dusted with purplish brown spores even before tearing away from the cap.

 Gills: Attachment adnate to adnexed. Grayish coloration in young fruit bodies becoming nearly black in maturity.

Spores: Dark purplish brown, subellipsoid, 13 by 8 micrometres on 4-spored basidia

Formerly misrepresented as Psilocybe azurescens.

B+ Spore Syringe Near Me

Detail of separable gelatinous pellicle: This feature seems to be unique to the “B+” among cubensis. When young and fully hydrated the cap has a transparent amber colored layer of cells that quickly oxidizes upon removal to a more opaque blue grey colour. The texture is like a thin stretchable layer of gelatin. Note the area where the pellicle has been removed is dull.

Strain Origin:  The origins of the B+ variety have become a thing of legend. B+ is a classic  variety, one of the most popular commercial cubensis variants in history. It has been heavily domesticated over decades of generational manipulation.

Nobody knows where the first Psilocybe cubensis spores which became “B+” were from.

“Mr G” who is responsible for the creation of  B+, swears it is a Psilocybe cubensis Psilocybe Azurescens hybrid. Most people disagree with this statement.  This claim has been widely discredited and proven to be a marketing ploy. Nobody has been able to prove the B+ is a hybrid of any kind. It would be rather miraculous if Mr. G. succeeded. It is safe to say his claims are beyond reasonable belief.

There is no evidence to suggest the species P. Cubensis and P. Azurescens can be crossed in the way he claims. Although some people say the caps of B+ resemble the cap of P. Azurescens, this is more likely than not, wishful thinking.

To further the B+ mystery, for a time, Sporeworks accidentally sold a different variety (the prime suspect is PES Amazonian) under the B+ label. This mistake has since been corrected, but there may be several different ‘strains’ floating around the trade community under the name B+.
