Wasson did not "discover" magic mushrooms, he was just the first white person to write about taking them. There were earlier reports on mushroom ceremonies, that is why Wasson went there.
Well, considering that magic mushrooms are native to Europe (and Africa and Asia) and there is ZERO Greek, Latin, Sanskrit or modern language textual evidence, I think it is fair to say he discovered magic mushrooms in the same sense as Columbus discovered America.
So, basically, I 100% agree with you. But pretty nuts that no one knew about them in Asian, Africa, Europe and most of the Americas until Wasson!!
