- Also called
- Derrumbe (shared common name with P. caerulescens), Psilocybe candidipes, Psilocybe bolivarii, Psilocybe sanctorum
A 2023/24 peer-reviewed paper documented a reproducible protocol: coir/vermiculite substrate at a steady 20-22C, fine ultrasonic fogging instead of spray misting (spray caused fruit abortion). Spawn-to-substrate ratio 1:2-1:5.
