Bayou is a strain from WillyMyco’s breeding program, and it takes a different direction from Tsunami. Where Tsunami emphasises clean uniformity, Bayou leans into the rugged characteristics of its Southern US namesake — the strain reportedly draws on genetics adapted to warm, humid conditions. The name evokes the bayou landscapes of Louisiana and the Gulf Coast, and the genetics deliver a fruiting body profile that matches: robust, vigorous, and adapted to heat.
Microscopy Characteristics
Bayou spores are ellipsoid, dark purplish-brown, measuring approximately 8.5–10 x 5.5–7 micrometres. Cell walls are moderately thick with a visible germ pore. Spore output is good to very good — Bayou produces dense, dark deposits that prepare well for slide work. Like Tsunami, the stabilization inherent in deliberate breeding tends to produce more uniform spore size distributions than wild-collected genetics. The overall profile is stockier than Tsunami.
Strain Background
Bayou was created by WillyMyco, the same breeder behind Tsunami. The name Bayou reflects the strain’s reported adaptation to warm, humid Southern US wetland conditions. Bayou entered circulation alongside Tsunami in the late 2010s. Together, they demonstrate how a single breeder can select for distinctly different trait profiles: Tsunami for clean uniformity, Bayou for environmental robustness.
Storage & Handling
Store at 2–8°C (35–46°F) in a dark location. Do not freeze. Viable for 6–12 months when properly refrigerated. Shake gently before use to redistribute settled spore material.
Frequently Asked Questions
What is the difference between Bayou and Tsunami?
Both are WillyMyco genetics, but selected for different traits. Tsunami emphasises clean uniformity. Bayou is vigorous and was selected for robustness and adaptation to warm, humid conditions.
