A non-destructive method using FTIR-ATR spectroscopy combined with OPLS-DA chemometric analysis can distinguish hallucinogenic mushrooms from edible and toxic species, even though specific psilocybin or psilocin bands were not identified. The technique successfully separated hallucinogenic mushrooms from others, making it a promising initial screening tool for forensic identification of seized samples. The study analyzed 64 mushroom samples from various genera, including hallucinogenic, edible, and toxic species.
