Concentrations of total mercury were determined in the fruiting bodies and underlying soil substrate to Parasol mushroom (Macrolepiota procera) collected from various sites in Poland in 1994-2000. Mean mercury concentrations of the caps varied between $1100 \pm 240$ and  $4900\pm 3100$ ng/g dry matter (total variation from 50 to 13000 ng/g), while of the stalks were between $530\pm 120$ and $2800\pm 1300$ ng/g (50-6200 ng/g). The BCFs of mercury varied, depending on the site between  $20\pm 1$ and  $220\pm 140$ (total range 17-720) for the caps and between $11\pm1$ and  $110\pm 97$ (total range 9-450) for the stalks. The mercury concentrations of the caps and stalks with exception of the one sampling site examined were independent of the soit substrate concentration what suggests a species-specific ability of M. procera to pick-up mercury.
