The author expresses his gratitude to the associated professor of the department of botany of the Belarusian State University T. A. Sautkina for the help in authentication of Mentha spicata and for valuable consultations and to the laboratory assistants of the department of botany of Belarusian State University E. A. Mitroshina and D. D. Burvel for a technical assistance at implementation of work.

Abstract

The data concerning the first findings of the micromycetes Peronospora stigmaticola Raunk. (Peronosporaceae, Peronosporales, Oomycetes, Oomycota, Chromista) within Belarus is presented. This species is an obligate parasitic pseudofungus and causes downy mildew on the plants of the genus Mentha L. and Satureja L. Sporulation is formed only on the flowers of the host-plants. We supply data about distribution of this micromycetes, its chorologic features, host-plants and symptoms of downy mildew on flowers. Micromycetes P. stigmaticola is found on the flowers of Mentha spicata L. in the one location of Belarus. We provide a brief morphological description of this pathogen based on the assessing of collected samples. The herbarium samples that are referred to in our work and serve as the grounds for this article are retained in Belarusian State University Herbarium (MSKU). The results of this research work extend our knowledge of morphometric characteristics and distribution of pseudofungus P. stigmaticola and might be taken into consideration when compiling the inventory of mycobiota of Belarus. The information about possible host-plants P. stigmaticola in Belarus is valuable for the detection of diseased plants and development of measures for protection cultivated plants of the genus Mentha L. and Satureja L. from downy mildew of flowers.
