Overview
B+ is one of the most recognizable and widely circulated varieties of Psilocybe cubensis. Emerging within the mycology community during the early 1990s, the genetic developed a reputation for its substantial fruiting bodies, classic coloration, adaptability, and consistent characteristics.
More than three decades after its introduction, B+ continues to be preserved within mycology collections and remains a classic example of P. cubensis morphology.
Origin and History
The exact history of B+ is somewhat unclear, as is the case with many Psilocybe cubensis varieties that entered circulation before genetic documentation became more common.
B+ is generally associated with Florida and is commonly attributed to a cultivator known as Mr. G, who reportedly introduced and distributed the variety during the early 1990s. From there, the genetic spread throughout the mycology community and became increasingly well known.
Because much of the early history of B+ was passed between cultivators and collectors rather than formally documented, details surrounding its original development should be regarded as commonly reported history rather than definitively established fact.
Regardless of the uncertainty surrounding its earliest development, B+ went on to become one of the most widely recognized P. cubensis varieties in circulation.
Appearance and Morphology
B+ exhibits many of the characteristics associated with classic Psilocybe cubensis morphology.
The variety is known for producing substantial fruiting bodies with thick, sturdy stems. Caps typically display caramel, golden-brown, or tan coloration and can become relatively broad as they mature.
Cap shape and coloration may change throughout development, while individual specimens can vary considerably in size and appearance. As with other P. cubensis genetics, morphology is influenced by both genetic expression and environmental conditions.
Growth Characteristics
One of the characteristics historically associated with B+ is its adaptability.
The variety developed a reputation within the mycology community for vigorous and relatively consistent growth across a range of environmental conditions. This adaptability contributed significantly to its widespread distribution during the 1990s and beyond.
Its ability to express recognizable characteristics under varying conditions also helped establish B+ as a commonly preserved P. cubensis genetic.
Potency
B+ has historically been described as falling within the general potency range associated with traditional Psilocybe cubensis varieties.
However, potency cannot be reliably determined from a variety name alone. Concentrations of psilocybin and related compounds can vary between individual specimens, genetic expressions, and environmental conditions. Analytical testing is required to determine the chemical composition or potency of a specific specimen.
Popularity and Legacy
Since entering circulation in the early 1990s, B+ has become one of the most recognizable names associated with Psilocybe cubensis.
Its combination of classic morphology, adaptability, substantial fruiting bodies, and decades of preservation within the mycology community has contributed to its longevity.
While countless new P. cubensis genetics have emerged since B+ was first introduced, it remains an established variety and an important reference point when comparing the morphology and characteristics of newer genetic lines.
For microscopy researchers and collectors, B+ represents a classic P. cubensis genetic with decades of history within modern mycology.
