Information on the distribution of a new invasive powdery mildew, Podosphaera amelanchieris Maurizio, recorded on Amelanchier alnifolia Nutt. and A. spicata (Lam.) K. Koch (Rosaceae) in Belarus and Ukraine is provided. The fungus was first found in 2000 in Belarus (Minsk), then in Sofiyivsky Park (Cherkasy Region, Ukraine), and later again in Belarus (Gomel and Minsk Regions) and in Ukraine, in Kharkiv, Kyiv and Volhynian Region. The Belarusian and Ukrainian specimens appeared to be identical, their morphological characteristics corresponded to the European samples of P. amelanchieris described by U. Braun and R. Cook. Chasmothecia of P. amelanchieris ex A. spicata and P. clandestina (Wallr.) Lév. parasitizing Crataegus sp. and Mespilus germanica L. were compared. It was found that the former fungus has longer appendages with more compact apices.
