The six heavy-metals and ten minerals in ten wood-rotting mushrooms were determined. Pb was not detected. Cd (0.02–0.32 mg/kg), Hg (0–0.05 mg/kg), and As (0.04–0.82 mg/kg) did not exceed Chinese standard levels, except for the Hg (2.15 mg/kg) in one Oudemansiella raphanipes sample. Auricularia heimuer had high levels of Ca (11 209 mg/kg) and Fe (603.54 mg/kg), indicating its suitability as a functional food. O. raphanipes with high contents of Fe (192.66–682.62 mg/kg), Zn (88.11–107.17 mg/kg), and K (17 273–22 560 mg/kg), which can be used as health food to supplement Fe, Zn, and K simultaneously. Pleurotus citrinopileatus was rich in Se (0.11–0.47 mg/kg) and it can be used as a Se-rich supplement (0.1–10 mg/kg). Ca and Mg, P and K, and K and Mg were highly and significantly positively correlated, indicating that they could co-accumulate in the mushrooms.
