P. Cubensis “B-Xtra” Spore Swab Pack


If you want to buy B-Xtra swabs be cautious as they are considered to be “active spores” which are for microscopy or artistic purposes. We will not complete your order if you contact us regarding the cultivation of active spores. Similarly, for legal reasons if you mention cultivating active spores or ask for cultivating advice, you will be subsequently banned from the site.

These spores are from a species that produces psilocybin and psilocin. For legal reasons they can only ship to 47 out of the 50 United States. Shipping is unavailable to California, Idaho, and Georgia.

Sonoran Spores acquires these spores and photos from outside, trusted sources in a legal manner. Further, Sonoran Spores does not condone or participate in the cultivation of psilocybin/psilocin producing or “active” species. Sonoran Spores also does not have any mycelium or fruiting bodies of psilocybin and psilocin producing species. We will not sell any products containing this so do not ask.

Spore Visibility Disclaimer: When you buy B-Xtra mushroom spore swabs, visibility is dependent on the characteristics of the spores themselves. As a result, not all spore swabs will look the same visually. All swabs are unique and may not look identical to each other or the picture above. Despite these visible differences, spore swabs are still viable for microscopy research.

B-Xtra Information

B-Xtra is a brand new Cubensis isolation that you will only be able to find here at Sonoran Spores! Similar to how OG TAT is an albino Golden Teacher, B-Xtra is an Albino isolate of the classic and ever popular B+ variety. It’s another variety brought to us by our amazing spore provider, Quest. These spores are perfect for researchers who are looking for new and rare genetics. 

While B-Xtra is an isolate of B+, the specimens can bear a resemblance to Penis Envy with very thick stems, especially in comparison to their smaller than average caps. Just something else that makes them so unique! This new variety definitely belongs in every collector’s library.

Microscopic Features

Be sure to take into consideration that because B-Xtra is an albino variety, they will have transparent spores. When spores are clear they can bruise blue leading the swab to appear blue to the naked eye. However they will be clear when viewing underneath the microscope. The spores are subellipsoid (ellipse) shaped and they are present on a 4-spored basidia. They are approximately 13×8 micrometers in size.

Each B-Xtra spore swab pack will come with:

  • 2 sterile swabs of P. Cubensis “B-Xtra”
  • 1 alcohol prep pad
  • 1 sticker (1 per order)
