The History and Experience of Psilocybe Cubensis B+ Strain

The history behind the Psilocybe cubensis B+ strain is somewhat mysterious. Unlike other varieties with well-documented backgrounds—such as Psilocybe mexicana—B+ magic mushrooms are believed to have been developed for the recreational community by a cultivator known only as “Mr. G.” Though stories about Mr. G have circulated for years, no concrete evidence about his identity has ever surfaced. However, it is widely accepted that B+ originated along the coast of Florida. The strain is often praised for its impressive resilience. In fact, B+ substrates have been known to fruit naturally even after being discarded in gardens, sometimes reappearing a year later.

Origins and History

The exact origins of the B+ strain are somewhat mysterious, though it’s widely believed to have been developed by a cultivator in Florida in the 1990s. It quickly gained a reputation for being easy to grow and capable of producing impressively large fruiting bodies—some of the biggest among cubensis varieties.

Key Characteristics

  • Appearance: B+ mushrooms typically feature large, golden-brown caps with a smooth, domed shape. Their stems are thick, white to off-white, and sometimes bluish when bruised—an indication of active psilocybin.

  • Growth Behavior: This strain is highly adaptable and grows well in a variety of conditions and substrates, including BRF cakes, coir, and manure. It thrives both indoors and outdoors, making it perfect for beginner cultivators.

  • Spore Color: Dark purplish-brown spores, ideal for microscopy and mycological study.

Experience and Effects

Those who have experienced B+ often report a warm, euphoric, and visual journey, described as both grounding and uplifting. It’s considered a “gentle giant” in the world of Psilocybe cubensis—potent enough for a powerful trip, yet often forgiving in intensity. Ideal for those seeking emotional clarity, visual exploration, or introspective insight.

Ideal for Beginners and Experts Alike

Whether you’re just starting your mycological studies or are looking for a reliable, high-yielding strain, B+ delivers consistency and quality. Its strong colonization rate and resistance to contamination make it one of the most beginner-friendly strains available.

If you’re ready to delve into the fascinating world of magic mushroom spores, the Psilocybe cubensis B+ strain is an excellent place to start. With its legendary reputation and forgiving nature, it’s easy to see why B+ remains one of the most popular strains worldwide.

Appearance and Growth Characteristics

B+ mushrooms are visually striking. With their button-like caramel brown caps, accented by golden highlights, they often appear as though they belong on a gourmet shelf rather than in the wild. The stems are thick, juicy, and substantial, often much larger than those of other Psilocybe cubensis strains.

One of the standout traits of the B+ strain is its abundant spore production, making it an excellent choice for those interested in creating their own spore prints or studying under the microscope.

B+ mushrooms are also highly prized for their fruiting capabilities. The caps can grow to an impressive 3–4 inches in diameter, and the strain is known to produce multiple flushes. It was specifically bred for its ability to fruit generously and reliably, making it a top pick among cultivators.

Everyone’s physiology and metabolism are different, and individual brain chemistry and body size play a significant role in how one may respond to psilocybin. Your environment and emotional state are also crucial factors. If it’s your first time—or if you’re significantly increasing your dosage—it’s important to choose a safe, comfortable, and ideally familiar setting. Consider having a sober trip sitter present to help guide and support you throughout the experience. For those seeking a lighter, microdosed effect, psilocybin tea is often a gentle and enjoyable option.

What to Expect with B+ Magic Mushrooms

The effects of B+ magic mushrooms typically begin within 10 to 40 minutes after ingestion and can last between 3 to 6 hours, depending on the dosage and individual physiology. Like all tryptamines, psilocybin can induce what users often refer to as “the mushroom yawns,” which tend to increase as the peak approaches. However, despite the yawning, the overall bodily sensation is energetic and alert, not tired.

Users may experience a broad spectrum of effects, ranging from the mystical, euphoric, and insightful to the hyperspatial and deeply introspective. At doses above 2 grams, many report visual field distortions, melting or warping objects reminiscent of Salvador Dali’s art, and effects such as:

  • Time dilation

  • Closed- and open-eye hallucinations

  • Synesthesia (e.g., “seeing” sounds or “feeling” colors)

Tips for a Safe Experience

  • Stay hydrated, especially if you’re outdoors or engaging in physical activities like dancing.

  • Sip honey ginger tea to help ease any nausea during the come-up.

  • Do not mix psilocybin with other substances, particularly alcohol or other drugs.

  • Do not use if pregnant or if you have a history of mental health conditions without professional guidance.

Above all, plan ahead and approach the experience with intention and respect. Safety, preparation, and mindset are key to a positive and transformative journey with magic mushrooms.
