How Many Psilocybin Mushroom Species Exist?
There are ~165 confirmed psilocybin-producing Psilocybe species, plus 10+ other genera. Here's the 2024 count and the gene transfer story that connects them.
Panaeolus, Gymnopilus, and Other Psilocybin-Containing Genera
Which non-Psilocybe genera contain psilocybin — Panaeolus, Gymnopilus, Inocybe, Pluteus, Pholiotina — and why horizontal gene transfer, not independent evolution, explains all of them.
