Forensic profiling is a tool to provide high resolution forensic information for sample matching, species determination and geographic origin of a biological sample. To demonstrate the methodology, HR-LC/MS was combined with multivariate statistical data analysis on 94 mushrooms from five different <i>Amanita</i> species, collected in four different European countries. Dry mushrooms were extracted with methanol and the extracts were analysed with HR-LC/MS. The 725 most abundant peaks were used for Partial Least Squares Discriminant Analysis (PLS-DA). The statistical models have the power to resolve the five different Amanita species in the first four principal components. In addition, it was possible to identify the geographic origin of the A.phalloides samples in a separate model.
