What do you mean "non-native enviroments"? Wood chips? The mushrooms are native to the area for at least decades, probably millennia.. they are common.
Did you miss the part where the full blown professional mycologist says that the mushroom is common -- his words -- in GGP? As does the Psychedelic Society of San Fransisco?
Did you read any of the links I provided?
Who should we listen to? The self styled amature? Or the experts and people who discovered the mushroom?
