During my extensive research I can't remember to ever have seen any other tryptamines mentioned as being in mushrooms than psilocin, psilocybin, baeocystin, norbaeocystin and serotonin. Baeocystin and norbaeocystin are analogs of psilocybin found in trace quantities in mushrooms that also have psilocybin and psilocin.
Baeocystin is active and norbaeocystin is likely to be, but hasn't been researched. Serotonin does not cross the blood-brain-barrier, so mushrooms containing this tryptamine is therefore inactive, even with a MAOI.
I would be highly interested to be proven wrong, but I doubt any other tryptamines that may be psychedelic have been identified in mushrooms, edible or not.
