must be cold temperate region, growing in wood chips, i know this is pretty much like a description of Auckland at least, i lived there a year and in the autumn after temps dropped below 10 there was at least 4 different species of psilocybin mushrooms and the most awesome were the Aucklandii, which were aka "caramel caps" and there was a "wavy cap" variant that grew bigger and had wavy caps, and another that was like this golden dome shaped one, which i think was growing on eucalyptus, i forget what the fourth kind was, but you could find these mushrooms everywhere, in every parkland, in every garden
