Abstract

Five mushroom species, P. ostreatus, P. ostreatus var. salignus, P. eryngii, P. florida, P. sajor-caju, threecontaminant fungi A. niger, P. italicum, R. stonolifera, andbarley, sorghum and wheat grains were used in the study. The purpose of this work was to determine mycelial growth of Pleurotus spp. and their competition with contaminant fungi. The Pleurotus spp. were grown better on the sorghum grains than the barley and wheat grains according to mycelial growth and density. The colony growth of Pleurotus spp.was inhibited by A. niger, P. italicum and R. stonolifera by 13.84%, -1.58% and 24.48%; 9.84%, 20.31% and 18.06%; 14.48%, 100.00% and 100.00% on the 3 rd, 5 th and 7 th days after inoculation, respectively.The mushroomswere completely suppressed by R. stonolifera on the 5 th day.
