Abstract: Spent substrate of <i>Agaricus bisporus</i>, <i>Pleurotus sajor-caju </i>and <i>Lentinula edodes </i>was evaluated for decolorization of 4 different dyes under different cultural conditions (media, incubation temperature and medium pH). Potato dextrose broth media supported highest decolorization (90% of Rhodamine B and Methyl Violet 2B, 93% of Chicago Sky Blue 6B and 88% of Quinaldine Red) after 3 days of incubation with <i>P. sajor-caju </i>spent substrate. Optimum pH requirements were 7.0 and 10.0 for Rhodamine B and Methyl Violet 2B with spent substrate of <i>L. edodes</i>, while 4.0 and 7.0 with <i>A. bisporus </i>and <i>P. sajor-caju.</i> However, for Chicago Sky Blue 6B and Quinaldine Red, it was 4.0 and 7.0 for spent substrates of all 3 mushrooms. Spent substrate of <i>A. bisporus </i>supported highest decolorization of Rhodamine B (93-95%) and Methyl Violet 2B (91-100%), followed by <i>L. edodes </i>+ <i>P. sajor-caju</i>. Temperatures of 25 and 35<sup>o</sup>C were most effective for decolorization of Rhodamine B (90%) and Methyl Violet 2B (97%) with spent substrate of <i>A. bisporus </i>alone. In case of Chicago Sky Blue 6B and Quinaldine Red, temperature requirement for decolorization was same but with spent substrate of <i>L. edodes</i>, <i>P. sajor-caju </i>and <i>L. edodes </i>+ <i>A.</i> <i>bisporus </i>for Chicago Sky Blue 6B, and <i>A. bisporus</i>, <i>P. sajor-caju </i>and <i>L.edodes </i>+ <i>A. bisporus </i>for Quinaldine Red.
