The goal of this study was to compare the mineral composition of Lentinula edodes (Berk.) Pegler fruit bodies available on the Polish and German markets in 2019 and grown in 5 countries in Europe and Asia.Organically-cultivated fruit bodies from Europe contained a higher amount of K, Mg and Na but also a lower level of rare earth elements than traditionally cultivated L. edodes from Asia. The highest mean contents of K, Mg and Na were determined in mushrooms from Polish organic food stores (21,700; 1,330 and 144 mg kg⁻¹, respectively). The highest mean content of Al, As, Au, Ba, Cs, Li, Os, Pb, Pt, Sr, Th, Ti and V was determined in dried Vietnamese L. edodes (91.2, 7.09, 0.168, 5.23, 35.0, 0.400, 0.189, 1.07, 1.77, 1.86, 0.172, 4.58 and 0.251 mg kg⁻¹, respectively) with no significant differences in Cd and Hg content between all the studied groups of mushrooms.The highest content of all elements was determined in traditionally cultivated L. edodes fruit bodies from Vietnam and organically-cultivated mushrooms from Poland. The results revealed similarities in terms of the total content of elements, but a different mineral composition, thus providing important information for potential consumers of this mushroom species.
