For the first time, 21 species are reported for the region: Erysiphe astragali, E. azaleae, E. howeana, E. hypophylla, E. lycopsidis, E. macleayae, E. prunastri, E. russellii, E. syringae-japonicae, Golovinomyces ambrosiae, G. asterum, G. bolayi, G. fisheri, G. riedlianus, G. verbasci, Neoerysiphe galii, Phyllactinia fraxini, Podosphaera aucupariae, P. phtheirospermi, P. prunicola, and Sawadaea tulasnei. The most common species were Blumeria graminis, Erysiphe alphithoides, E. aquilegiae, E. divaricata, E. ornata, E. polygoni, Podosphaera aphanis, and P. myrtillina. Erysiphe heraclei, Neoerysiphe galeopsidis, and Podosphaera erigerontis-canadensis were recorded quite frequently. Erysiphe arcuata, E. astragali, E. azaleae, E. baeumleri, E. circaeae, E. cruchetiana, E. cruciferarum, E. grosulariae, E. hypophylla, E. lythri, E. macleayae, E. palczewskii, E. penicillata, E. pisi, E. prunastri, E. russellii, E. vanbruntiana, Golovinomyces ambrosiae, G. asterum, G. circumfusus, G. cynoglossi, G. fisheri, G. inulae, G. riedlianus, G. verbasci, Neoerysiphe galii, Phyllactinia fraxini, Ph. guttata s.str., Podosphaera amelanchieris, P. aucupariae, P. balsaminae, P. macularis, P. mors-uvae, P. prunicola, and Sawadaea tulasnei are known from one or two localities, so they are considered as rare species in Western Polissya of Ukraine.
