penicillin and mushrooms are not similar, the ingredients psilocybin and psilocin are similar in spelling but are vastly different, you should be fine, if you are feeling very paranoid then eat a smal chunk of one, wait 24 hours, if you have no signs of an allergic reaction then you will be fine, although i am very sure that you will have no problems Penicillin and ampecillin are produced (synthetically)-->from certain molds, mushrooms not being one of these molds..Although you can grow penicillin when trying to grow mushrooms a good rule of thumb is if it fruits there is no penicillin present.
