¹ Homoscedasticity among mushroom samples was tested by the Levene test: homoscedasticity, p > 0.05; heteroscedasticity, p < 0.05. ² p < 0.05 indicates that the mean value of at least one component differs from the others (in this case, multiple comparison tests were performed). p-Value (n = 81). For each mushroom sample, means within a column with different letters differ significantly (p < 0.05). nd = not detected.
