     The study investigates the possibility of three types of R.rosulus, S.varigatus, P.involutus in removing and lowering the ascending concentrations of copper and zinc elements, and during three incubation and contact periods (5,7 and 10 days) and comparing the growth of isolates with control samples. Type P.involutus is the most efficient in the removal by observing the growth of isolates by increasing its diameter compared to the control samples and the concentrations of copper and zinc and for all the days of incubation, while the type S.varigatus was the highest growth at the low concentrations of copper and zinc only and for all periods of incubation, the type R.rosulus. The diameter  was smaller as compared to control samples All elemental concentrations of copper and zinc except at concentration (2.5 ppm), and is generally observed increase diameters of the isolates of the three types of increasing periods of incubation and all elemental concentrations of copper and zinc, and this increase is less than at high concentrations of these elements and of all species studied.
