Guapiles.

What's known

Here's what's meant to be true and not.

What we actually know

• It is a wild-collected strain, reportedly gathered around the town of Guápiles in Costa Rica rather than isolated on a hobbyist's setup.
• Genetically it is a plain Psilocybe cubensis, the same species as Golden Teacher or B+. It is not a hybrid and not a separate species.
• Guápiles is a real place, the seat of the Pococí canton in Limón Province on Costa Rica's humid Caribbean lowland side, an hour or so northeast of San José by road (route 32).
• As a true geographic collection from cow pasture, it is a textbook coprophilic (dung-loving) cubensis taken from the kind of warm, wet, cattle-grazed ground the species favours.
• Its documented record is thin and recent. Most of what is written about it traces to vendor listings rather than peer-reviewed taxonomy or a long forum history.

What the community says

• It was collected by someone known only as Drew on the 10th of March 2021, in the fields around Guápiles. Treat the exact name and date as community lore, not verified record.
• Local guides remembered as Ice-Sunshine and Fab are said to have helped find it, and a share of sales is said to go back to them. We cannot independently confirm any of this.
• One guide, Fab, is quoted saying the fields of Guápiles are spiritually important to locals and that spirit guides will take your hand and lead you to the mushrooms. Lovely image, firmly in the realm of folklore.
• Because it is a recent name, you will sometimes see conflicting years attached to it (a 2021 wild collection versus a later isolation from spore). The strain is young enough that its paper trail has not fully settled.

Where it came from

Most of the famous cubes are lab strains, strains that someone selected, named and settled indoors over many generations. Guapiles is the other kind. By the accounts that exist it is a wild collection, gathered from the cattle fields around the town of Guápiles in Costa Rica and then put into circulation more or less as nature handed it over. That makes it less a brand and more a postcode, a snapshot of Psilocybe cubensis doing what it has always done in the warm, wet tropics.

Guápiles itself is real and easy to place. It is the main town and seat of the Pococí canton in Limón Province, sitting on the humid Caribbean side of the country, the gateway road northeast from San José down toward the coast. The habitat described is exactly what you would expect for a dung-lover: rough cattle pasture, big boulders scattered through the fields, hillsides that drop away into sudden little cliffs. The story goes that it was picked up by someone known only as Drew in March 2021, apparently with help from local guides. We pass that along as lore, because that is what it is.

It is less a brand than a postcode: a snapshot of a tropical dung-lover, collected from cow pasture and shared roughly as it was found.

What to expect at the scope

Here is the part. Guapiles is a recent strain with a thin documented history. Almost everything written about it traces back to a handful of vendor listings rather than to herbarium records, a published description, or years of forum chatter. You will even see different years pinned to it depending on who is telling the story. None of that makes it less interesting as a collector's strain, a genuine geographic cubensis is a fine thing to have on a slide, but it does mean the romance around it should be read as romance. Under the microscope it is, reassuringly, just a very ordinary and very good Psilocybe cubensis.
