In Bemis v. State, the defense argued that because Indiana law only mentions psilocybin and not mushrooms, the law was unconstitutionally vague as shown in Florida v Fiske. The case went to Indiana Court of Appeals which ruled Florida v Fiske did not apply because the defendant knew the mushrooms contained psilocybin.
