Abstract

Economic development of the Arctic contributes to distribution of new alien fungal species to the north. In the Taimyr region, 38 species of powdery mildew fungi have been identified, 25 of which are new for the region. Alien and cryptogenic species account for 52.6% of powdery mildew fungi. Fungi were found on 53 host plant species, 28 of which are new for the Russian Arctic. Among the host plants, the share of alien and cryptogenic species is 45.3%. In contrast to the data for alien flora, the proportion of alien species in the mycobiota decreases from north to south, although this result requires further verification.
