B+ mushroom strain (BPLS)

Species: Psilocybe cubensis
Family: Penis Envy family
Potency reputation: average
Grow difficulty: easy

Origin

Psilocybea attributes B+ to a cultivator known as Mr. G, who reportedly stabilized and shared it through hobbyist networks in the 1990s. This attribution is not independently established in the supplied sources.

Lineage

Psilocybea identifies Tidal Wave as a descendant of B+; no further lineage is given.

Appearance

Described as having caramel-tan caps that pale toward the margins, thick pale stems that bruise blue-green, and deep purple-black spores. Sources differ on size: psilocybea gives typical cap widths of 50–100 mm, while Zamnesia says some specimens can reach 30 cm.

Cultivation

Psilocybea describes it as beginner-friendly, broadly tolerant, and fast-colonizing. Zamnesia says its kits can produce multiple flushes; neither source gives a comparable yield measurement.

Reported effects

Zamnesia markets the variety as producing a positive experience and claims onset nausea may be less pronounced than with other varieties. These are seller descriptions, not substantiated comparative findings in the supplied sources.

Good to know

Psilocybea says proposed expansions of the name “B+,” such as “better plus” or “big plus,” are community lore without authoritative documentation.

Lab results

Calculated sum of the reported mean psilocybin (11.1 mg/g) and psilocin (0.22 mg/g) measurements for lab-grown fruiting bodies; the source reports these separately, with uncertainties of ±2.5 and ±0.09 mg/g, respectively.

Sources

Psilocybin is a federally controlled substance. Legal adult access is limited to licensed programs in Oregon and Colorado. This profile is educational, not medical advice.
