Ectomycorrhizal mushrooms belonging to Boletales (Basidiomycota) viz. Boletus edulis Bull, Hortiboletus rubellus Krombh and Suillus sibiricus Singer were selected to evaluate their antifungal potential against some filamentous fungi viz. Aspergillus terreus Thom, Aspergillus niger Tiegh and Rhizopus stolonifer Vuill. Extracts of these selected mushrooms were prepared in methanol and their various concentrations (0%, 1%, 1.5%, 2% and 3%) were tested against selected pathogenic fungi. B. edulis showed maximum decline (51-53%) in the biomass of R. stolonifer, S. Sibiricus showed 40-45% decline in biomass of A. terreus, while all the concentrations of H. rubellus showed 50-55% decline in the biomass of A. niger. Present work revealed that selected indigenous mushrooms have strong antifungal potential against different pathogenic fungi. So, these mushrooms can be used as source material for fungal control methods.
