New Records of an Alien Fungus Erysiphe Corylacearum (Erysiphales, Ascomycota) in Ukraine

Abstract

This article provides information on new records of an alien powdery mildew fungus Erysiphe corylacearum (Erysiphales, Ascomycota), previously recorded in Ukraine only in Crimea and at two localities in Kyiv.

First report of Erysiphe corylacearum on Corylus avellana and C. colurna in Austria

“…MW031866), and representative voucher specimens were deposited in the fungarium of the University of Vienna (WU 43287, WU 43421, WU 43423, WU 43424, WU 43514, WU 43515, WU 43520, WU 43525). A nBLAST analysis revealed 99-100% identity to sequences of E. corylacearum, with 100% identity to sequences from Azerbaijan (LC270863), Iran (MF668615, MH047243), Japan (MT095104), Switzerland (MN822721-MN822723) and Turkey (KY082910), confirming the species identification.Native to East Asia and probably North America, E. corylacearum was first observed in Turkey in 2013 and has since rapidly extended its distribution range to West Asia as well as Eastern and Central Europe(Beenken et al, 2020;Heluta & Fokshei, 2020). Erysiphe corylacearum has been reported as a severe invasive alien pathogen, causing significant yield losses in hazelnut orchards in Turkey, Iran and Georgia(Arzanlou et al, 2018;Meparishvili et al, 2019).…”
