In order to answer this question, PERMANOVA was performed, the results of which indicated that the combined effect of all analyzed variables (elements concentration in soil, characteristics of soil, mushroom species) explained almost 80% of the variability of the elemental profile (R 2 = 0.79949) and was highly significant (F = 18.412, p = 0.001) (Table 6 ).
