From your second link:

Here we report the discovery, through global and targeted metabolomics supported by metagenomics and proteomics, of the plant amphetamine, cathinone, in Massospora cicadina-infected periodical cicadas, and the mushroom tryptamine, psilocybin, in M. platypediae- and M. levispora-infected annual cicadas.

It appears that the two chemicals come from two different fungi. Or I could be misinterpreting that.

Edit: PS. I appreciate all of the content that you post. I just thought this was an interesting subject.
