Ready to geek out and learn a little more? There are many varieties/subvarieties of cubensis mushrooms native to the country of Costa Rica. Many of these varieties look similar and it has become common to use the names “Costa Rica” and “Arenal Volcano” interchangeably. This, however, is incorrect.
The original Arenal Volcano specimen was discovered by mycologist “Rhino” in a pasture at the base of the Arenal volcano in northwestern Costa Rica during the late spring of 2016. The Arenal Volcano cubensis differs from other Costa Rican varieties due to the conditions in which it was found growing.
You see, the Arenal Volcano specimen was found at the end of the Costa Rican dry season; 2-3 weeks before any other Cubensis mushrooms emerged! This explains how the true Arenal Volcano variety shows extreme vigor in both colonization and fruiting stages. More importantly, Arenal Volcano displays these qualities even in the face of suboptimal conditions.

Syringe vs. Print: What's Best?
A spore syringe is a medical-grade syringe filled with mushroom spores suspended in sterilized distilled water; they’re easy to work with and ready for use right out of the box.
A spore print is the direct deposit of spores left by placing a mushroom cap onto a sterile surface like glass, foil, or paper. Prints can be stored long-term and utilized when needed. (Hydration of spores happens when put in a syringe, but there are other uses as well.)
For beginner researchers, syringes are the recommended starting point, with no prep work required. Explore the PNW Spore print collection to compare options.
We’ve got gourmet & medicinal liquid cultures in stock too!

Not only was the shipment process refreshingly prompt, but PNWS included a surprise glass slide, plus stickers. If I could give ten stars I would.
Thank you, Chris! This review makes our day. So happy to know you would give us 10 stars!
