Abstract

The Erysiphaceae are obligatory parasitic fungi that cause powdery mildew disease of green space plants. During this study, powdery mildew fungi were collected and identified from different localities of Ardabil landscape, Iran. Erysiphe rayssiae (on Spartium junceum), Erysiphe robiniae var. robiniae (on Robinia pseudoacacia) and Euoidium cf. agerati (on Ageratum houstonianum)are new records for mycobiota of Iran. Jasminum sp. is reported as Matrix nova for Erysiphe syringae-japonicae. Also this is the first record of Golovinomyces montagnei on Cirsium arvense and Golovinomyces orontii on Antirrhinum majus in Iran. The taxa including Erysiphe astragali on Astragalus sp., Erysiphe crucifearum on Brassica elongata, Erysiphe polygoni on Rumex sp., Golovinomyces cichoracearum on Cichorium intybus and Golovinomyces sordidus on Plantago sp. are newly found in Ardabil province. Furthermore, some specimens belonging to Podosphaera fusca s.l. were assessed. According to the new species concept, concerning these taxa, Podosphaera fusca s.s. was redescribed, and Podosphaera erigerontis-canadensis on Taraxacum sp. is reported for the first time, although previously reported from Iran under the Podosphaera fusca.
