Here are the major ones, other than baeocystin there is also the minor alkaloid norbaeocystin, and NMT and 4-HO-NMT present. DMT is also present as a biosynthetic precursor (just like the aforementioned compounds are).
But even those are in such small amounts and without confirmed significant effect that it begs the question if those are really
relevant. Psilocin and psilocybin are the major ones and even psilocybin may only be a pro-drug that turns into psilocin.
Conversely there may be complex potentiating compounds present. I wouldn't know about that.
Plenty can be found in this article:
