SUMMARY Three ectomycorrhizal fungi originating from Pseudotsuga menziesii plantations were exposed to cadmium (Cd) concentrations up to 10 μM. Laccaria bicolor and Lactarius hepaticus showed a much higher sensitivity to Cd than Lactarius rufus . At 1 μM Cd, reductions in radial growth and in dry weight production were 91 % and 95% in L. bicolor , 100% and 100% in L. hepaticus and 14% and 8% in L. rufus , respectively. Cadmium increased the lag time of radial growth in L. bicolor but not in the other fungi examined.
