Erysiphe azaleae, a new powdery mildew fungus introduced into Turkey

Abstract

In the current study, Erysiphe azaleae U. Braun U. Braun & S. Takam. Erysiphales, Ascomycota is reported for the first time from Turkey. A short description, host plant, locality and illustrations related to macro and micromorphologies of the species are provided. Erysiphe azaleae has been found only once on Rhododendron ponticum L. Ericaceae in Artvin province in the Black Sea region. This is the first report of this species in Asia, because the fungus known from the Russian Far East as E. azaleae is actually E. izuensis. The fungus formed both conidia and fruiting bodies. Thus, E. azaleae should be considered as a potentially dangerous powdery mildew pathogen for introduced and native rhododendrons in Turkey

Erysiphe azaleae, Türkiye’ye tanıtılan yeni bir külleme mantarı

Abstract

Mevcut çalışmada, Erysiphe azaleae U. Braun U. Braun & S. Takam. Erysiphales, Ascomycota Türkiye’den ilk kez rapor edilmiştir. Türün kısa deskripsiyonu, konukçu bitkisi, lokalitesi ve makro ve mikro morfolojilerine ait fotoğrafları verilmiştir. Erysiphe azaleae Karadeniz Bölgesinde yer alan Artvin yöresinde sadece Rhododendron ponticum L. Ericaceae bulunmuştur. Bu tür aynı zamanda Asya kıtası için ilk rapordur çünkü Rusya uzak doğusunda daha önce E. azaleae olarak bilinen tür aslında E. izuensis’tir. Bu mantar conidium ve fruktifikasyon organı oluşturur. Bu nedenle Erysiphe azaleae Türkiye’de doğal yayılış gösteren orman gülleri için potansiyel tehlike arz eden bir külleme patojeni olarak düşünülmelidir
