摘　　要：Twenty eight strains of endophytic fungi including sterile mycelia were isolated from the leaf,rhizome and roots of Hedychium spicatum Ham ex.Sm.Majority of the endophytic fungi isolated belonged to the phylum Ascomycota which accounted of about 84%.The endophytic assemblage was dominated by the class Sordariomycetes.Endophytic fungal genera such as Fusarium and Penicillium were found to be common to all the plant parts.Diversity of endophytic fungi was found to be highest in the roots(H’=2.43).Mucor hiemalis,Penicillium sp.,Penicillium expansum,P.simplicissimum,Phoma medicaginis,Trichoderma sp.and T.gamsii showed above 60%inhibition against the phytopathogen Alternaria solani.
