Identification of hallucinogenic fungi from the genera Psilocybe and Panaeolus by amplified fragment length polymorphism.

Unambiguous identification of the hallucinogenic fungi of the genera Psilocybe and Panaeolus is required by national and international drug control legislation. We report on a DNA-based test using the technique of amplified fragment length polymorphism (AFLP). AFLP can differentiate species of the two genera Psilocybe and Panaeolus by using different primer sets. The identification of hallucinogenic fungi using a DNA-based test, which can be used in conjunction with morphological features, will assist in forensic investigations.
