Psilocybe Cyanescens are identifiable by their signature “wavy” undulating cap. The species was first formally described in 1946 by Elsie Wakefield in her publication “Transactions of the British Mycological Society”, although she had been collecting the mushrooms since 1910. Over the last century psilocybe cyanescens has vigorously spread to almost worldwide presence due to its symbiotic relationship with human urbanization. It benefits from human activity primarily because its preffered growing environment is lichenous material such as wood chips, which are common in and along the perimeter of mulched plant beds, gardens, and maintained trails. The species is prized for its potency, containing on average 0.85% psilocybin and 0.36% psilocin. It can sometimes fruit in colossal quantity, under ideal conditions; more than 100,000 mushrooms were found growing in a single patch at a racetrack in England.
