The conidia of Blumeria graminis and Erysiphe pisi conidia were inoculated on a formvar membrane laid on an artificial medium. Germinated conidia frequently formed appressoria and then penetrated the membrane to form haustorium-like structures in the artificial medium. Secondary hyphae elongation was also observed after the formation of haustorium-like structures. These results suggested that the formvar membrane laid on artificial medium induced the formation of haustorium-like structures that have roles in the formation of secondary hyphae.Graphical abstract
