This study compared the mineral composition of fruit bodies of the edible mushroom Hypsizygus marmoreus (white and grey strains) produced in China and distributed in Poland with those cultivated experimentally in Poland. In total, 41 elements were determined using inductively coupled plasma optical emission spectrometry and the results were evaluated using various statistical methods. Principal component analysis pointed to similarity in the mineral composition of white H. marmoreus imported from China and obtained from experimental cultivation in Poland. The composition of elements in grey H. marmoreus fruit bodies from China and Poland was different. The Friedman test showed insignificant differences in the content of all 41 elements jointly among the 4 studied groups of mushrooms. The same insignificant differences were observed for 5 macroelements and the rest (36) of the elements jointly. Rank sum showed the highest load of 5 macroelements jointly in the grey strain from Polish experimental cultivation, while the lowest load of the rest of the 36 elements (including deleterious ones) was observed in the white strain from Polish experimental cultivation. The content of all 41 elements jointly in the studied mushroom groups was as follows: white strain (Poland) < grey strain (China) < white strain (China) < grey strain (Poland). Significant differences in total mineral content between white and grey fruit bodies of H. marmoreus, both from China and from Poland, and also for selected elements between white or grey strains from both countries (differences in cultivation), were indicated by the Welch Two Sample t-test (alpha = 0.05).
