Psilocybe maxima

Described by Josef Velenovský in 1921 in České Houby, his flora of Czech fungi. Like many Velenovský names it has seldom been recognised since; GBIF holds no specimens. Whether it contains psilocybin is not documented here; many Psilocybe do and are controlled in many countries, so check local law before any cultivation.
