Ultrastructure of cleistothecia and the stages of life cycle of Microsphaera palczewskii by scanning electron microscope

Abstract

Several year long investigations of the developmental cycle of Microsphaera palczewskii occurring on the leaves of Caragana arborescens in Central Poland are reported. The material was studied with light and scanning electron microscopes. The scanning microscopy micrographs of the clistothecia and appendages presented in this report are the first micrographs of this species.
