Samples of five species of wild edible mushrooms, growing in the vicinity of Warsaw, were analyzed in order to determine discrimination factors (DF) for 137Cs and 40K in their caps and stipes. The obtained DF values range from 0.80 to 2.87, and seem to be characteristic of each species. A brief discussion of the observed phenomenon is presented.
