Smut fungi of Zailiysky Alatau have not been studied enough, despite the fact that they are of great
economic importance, like parasites of cereal plants. Therefore, the work purpose was to identify the
species composition of smut fungi in Zailiysky Alatau, to establish the range of their host plants and
distribution along the altitudinal belts. The scientific and practical significance of the work lies in the
discovery of new species of smut fungi for Zailiysky Alatau, obtaining data on their location and distribution. The material for article was the authors’ own collections from research area. Preparation of
specimens was carried out according to standard methods. The article presents a list of smut fungi on
the territory of Zailiysky Alatau (main ridge, Chu-Ili mountains, Sugaty, Boguty, Turaigyr), including 75
species from two classes, according to modern systematics. The genera Entyloma (18 species), Ustilago
(15), and Urocystis (11) are the most widely represented. The greatest variety of smut fungi (50 species) is
characteristic of the main ridge of Zailiysky Alatau, 27 – of Chu-Ili mountains, 4 – of Sugaty and Turaigyr,
3 species in Boguty. Ustilago cynodontis on Cynodon dactylon and species of the genus Anthracoidea
on Carex spp. are widespread throughout study area. Smut fungi were registered on 81 host plants from
15 families. Most smut fungus species affect cereal plants (33 species) and representatives of the Asteraceae (8) and Ranunculaceae family (6). 44 smut fungi are characteristic of monocotyledonous plants. The
greatest number of smut fungus species is observed in the ephemeroid-sagebrush-feather grass desert
steppes and typical forb-fescue-feather grass steppes (31 and 25 species, respectively). On subnival vegetation, only 2 species were recorded. The value of the study and its practical value lies in the discovery
of new species of smut fungi for Zailiysky Alatau, obtaining data on their location and distribution.
