Re: Indeed
All the fungal psychedelics are the products of some creative chemical evolution. I was highlighting that fungi are the source of a number of psychedelics rather than trying to draw a chemical similarity linkage. You wouldn't expect one as none of them are related.
A lot of the psychoactive substances in nature are in effect natural pesticides. If the creature chomping on you or sucking your sap gets too buzzed to continue you win. Think nicotine, caffeine, opiods, the base of ayahuasca, nutmeg and lots of others. That they have effects in both humans and insects shows neural systems evolved long before the split in our lineages.
