Psilocybe fimetaria is a dung-loving mushroom, usually found on horse dung. Along with Psilocybe fuscofulva, it is one of two Psilocybe mushroom species that has been found to contain no detectable levels of the psychoactive tryptamines psilocin, psilocybin, or others. In the case of P. fimetaria, this may be due to some individual specimens having a very low concentration, or the species actually being a pair of morphologically similar species.
