According to the results, Erysiphe species on Vicia faba and Sesbania punicea showed 100% similarity to each other, however, without ITS sequence of holotype of E. sesbaniae it is impossible to make conclusion whether Vicia faba powdery mildew fungus actually belongs to E. sesbaniae or E. trifoliorum complex. ITS sequence from isolate of Lagerstroemia indica powdery mildew showed 100% similarity to E. australiana. Podosphaera on Vigna fells into phylogenetic group containing P. xanthii on cucurbitaceous hosts. ITS sequence of chamomile (Matricaria chamomilla) powdery mildew fungus showed 100% similarity to P. xanthii on Xanthium strumarium. Molecular characteristics and morphological examination of conidia and conidia germination clearly showed that Dahlia powdery mildew in Guilan province is conspecific with G. spadiceus. Anamorph morphology and ITS sequence of Podosphaera on Epilobium and Erysiphe on Platanus orientalis showed that these species belong to P. epilobii and Erysiphe platani respectively.
