Occurrence of the sexual morph of Erysiphe macleayae on Chelidonium majus in Romania

Abstract

The sexual morph (chasmothecium) of Erysiphe macleayae on Chelidonium majus has been found in Romania for the first time. Although the asexual morph of this powdery mildew on C. majus is known from many countries, the occurrence of chasmothecia on this host is rather rare. A description of morphological characters and an analysis of the phylogenetic relationship of ITS sequences of the Romanian specimens are presented.
