B+ Liquid Spores

Making its way to the modern world, this ancient fungi that have been enchanting minds for centuries is making waves in the scientific community. From its origins to its caramel color to its potency, B+ mushrooms provide profound experiences and insights for psychonauts, seekers, and researchers looking to discover the world's greatest wonders.

B+ Liquid Spores are syringes that contain B+ mushroom spores held in a liquid medium. They allow researchers to explore the species in every facet, allowing the study of its hardiness, transform grain into mushroom spawn, or simply create an unlimited supply of liquid culture. While the discovery of B+ mushrooms remains a mystery, their roots are traced back to the lush landscapes of Central and South America. During this time, indigenous people used them for spiritual exploration and healing. Today, B+ mushrooms are used for the effects, discovery, and general research. You'll notice them by their flattened cap when matured, their dark caramel or chestnut color, thin, dark purplish-brown gills, and thick, whitish stem.

Whether you're looking to endure a spiritual awakening or explore under the microscope, researchers and enthusiasts will certainly enjoy the depths of this fascinating liquid spore. From its existing studies that have proven its potential to the beauty of its flattened cap, this is a fungus you have to learn more about.

Key Features

Large Robust Basidiospore Geometry

B+ is consistently noted in the Psilocybe cubensis research community for producing characteristically large, robust basidiospore deposits with wide spore geometry — a morphological profile that has made it one of the most reliable and research-accessible cubensis reference specimens across decades of consistent microscopy documentation.

Cleanroom Prepared

Every syringe is prepared in a controlled cleanroom environment using strict sterile technique, minimizing contamination and helping ensure clean, viable spore samples for microscopy.

Slide-Ready Sterile Suspension

Each 10cc syringe contains B+ basidiospores suspended in sterile aqueous solution — ready for immediate microscopy slide preparation without additional processing, delivering consistent large-profile spore density across the full syringe volume.

Decades of Community Research Documentation

Few Psilocybe cubensis strains match B+ for depth of community research documentation — decades of consistent availability and study have produced a comparative reference record that makes it one of the most well-characterized and reliably sourced baseline specimens in the cubensis microscopy research catalog.

Decades of research documentation behind a single strain — B+ remains the reliable baseline

B+ is one of the most extensively documented and consistently available Psilocybe cubensis strains in the research community — a variety whose origin, while debated, is commonly attributed to a Florida-based developer known as Mr. G in the 1990s, with some accounts suggesting a Southeast Asian or hybrid wild-collect component that has never been definitively confirmed. What is unambiguous is B+'s research legacy: characterized by large, robust basidiospores with characteristically wide spore geometry and reliable deposit density, B+ has served as a morphological reference point for comparative cubensis taxonomy across decades of community and academic microscopy documentation. It also holds a documented role as the B+ parental lineage in the Tidal Wave B+ × PE hybrid cross — a contribution to the catalog that further underscores its foundational place in Psilocybe cubensis genetic research.

Frequently Asked Questions

What is a B+ liquid mushroom spore syringe?
A B+ liquid spore syringe is a 10cc sterile aqueous suspension of basidiospores from the B+ strain of Psilocybe cubensis — one of the most extensively documented and consistently available cubensis varieties in the research community, commonly attributed to a Florida-based developer known as Mr. G in the 1990s. B+ is recognized for producing characteristically large, robust basidiospores with wide spore geometry and reliable deposit density, making it one of the most well-characterized baseline reference specimens for comparative Psilocybe cubensis microscopy and taxonomy research. All syringes are sold strictly for microscopy and research purposes only.
How do I store B+ liquid spore syringes?
B+ spore syringes should be stored refrigerated at 2–8°C (35–46°F), away from direct light and temperature fluctuations. Under proper refrigerated storage conditions, syringes remain viable for microscopy research for up to 12 months. Syringes should never be frozen, as ice crystal formation can damage basidiospore integrity and compromise slide preparation quality.
Does Magic Spore Labs ship B+ spore syringes to my state?
Magic Spore Labs ships B+ liquid spore syringes to researchers across the United States, with the exception of California, Idaho, and Georgia, where state law restricts spore shipments. All orders are packaged discreetly and securely and are sold strictly for microscopy and taxonomy research purposes only.
What is the origin of the B+ Psilocybe cubensis strain?
The origin of B+ remains a subject of debate in the mycology research community. The most widely cited account attributes its development to a Florida-based cultivator known as Mr. G during the 1990s, with some documentation suggesting a possible Southeast Asian wild-collect component to its genetic background — though neither the specific development process nor geographic origin has been definitively confirmed. What is well-established is B+'s role as a parental lineage in documented hybrid crosses, including the Tidal Wave B+ × Penis Envy cross developed by Melmac and RogerRabbit, whose lineage won the 2021 Psilocybin Cup — a connection that further anchors B+ within the cubensis research community's most documented genetic history.
How does B+ compare to Golden Teacher as a Psilocybe cubensis baseline reference specimen?
B+ and Golden Teacher are the two most broadly documented and widely available Psilocybe cubensis strains in the research catalog, and both serve baseline reference functions — but they differ in morphological emphasis. Golden Teacher is prized for its morphological consistency and its position as the most thoroughly documented comparative anchor in the cubensis species, with decades of published and community reference literature. B+ is distinguished by its characteristically large and robust basidiospore geometry — wider spore profile and reliable deposit density — which has made it particularly valued for researchers studying spore size variation and deposit yield across cubensis varieties. Together they form a complementary baseline pair: Golden Teacher for documentation depth, B+ for morphological scale.
Disclaimer: Psilocybe cubensis spores are intended for microscopic research and identification purposes only. Not for human consumption. Not for sale in CA, ID, FL, or GA. Any communication implying intent to cultivate will result in order cancellation and future purchase denial.
