The paper deals with results of the study of cleistothecia of the powdery mildew fungus Microsphaera on oaks in Slovakia, following the previous part focused on conidial stages. Based on taxonomic characters of cleistothecia (size, appendages, asci and ascospores), the identity of Slovak isolates was evaluated in comparison with Microsphaera alphitoides and M. hypophylla. All taxonomic characters were measured and analyzed from samples collected from both sides of leaves of various oak species.
