Wavy Cap Mushrooms (Psilocybe Cyanescens) spore print

The Wavy Cap, aka Cyanescen is commonly found in wood chips growing in temperate regions around the world. Fruiting typically occurs between late October and February for Northern California, and fruiting in other areas generally occurs in fall, when temperatures are between 10-18 °C (50-65 °F).
 
Wood lovers require a wood based substrate to form primordia. The higher carbon to nitrogen ratio found in wood chip substrate is responsible for these varietys higher potency. The higher the C:N ratio the more active is produced.
