Selenium biofortification in edible mushrooms whose consumption is rising with increasing interest in healthy diets as a strategy to mitigate Se deficiency in the human diet. This study investigated the effects of Se supplementation (0, 0.1, 0.2, and 0.4 mg kg−1) in the growing medium on yield, morphological traits, and mineral composition of two edible mushroom varieties: white button (Agaricus bisporus L. Sing) and chestnut (Agaricus brunnescens). Increasing Se concentrations slightly improved the fresh weight of both species, with a statistically significant enhancement observed only in the white button variety. Selenium treatments had a marginal impact on cap diameter in the white button mushrooms, while no significant changes were observed in cap length, stipe diameter, or stipe length for either variety. Selenium concentration increased significantly in both species with the increasing Se doses; however, chestnut mushrooms consistently accumulated approximately twice the amount of Se compared to the white button mushrooms. The application of 0.2 mg kg−1 Se significantly increased N concentration in both varieties. In the chestnut variety, 0.1 mg kg−1 Se slightly reduced P and K, whereas the same dose significantly increased Ca in the white button variety. Magnesium and S concentrations were unaffected by Se treatments, while Fe and Zn levels increased in the white button mushrooms. These results suggest that Se biofortification enhances Se accumulation especially in chestnut mushrooms without major yield loss and improves some nutrients (N, Ca, Fe, Zn).
