Haha, well, in the links section of
Amanita (sic!)
Design website there is a link to Erowid. Also, there's mushrooms suspiciously similair to certain
Psilocybes all over the place both in
Samorost 2 and
Machinarium. Not to mention JD toking a huge bong in the first
Samorost.
Not that it really matters, though
