Аннотация:Long-term microbiological analysis of birch (Betula pendula) pollen from Moscow and Moscow region showed that about a third of the analysed samples contain fungus Quambalaria cyanescens (de Hoog & G.A. de Vries) Z.W. de Beer, Begerow & R. Bauer. This fungus was known earlier mainly as symbiont of tropical plants Eucalyptus and Corymbia and was not registered in Russia. We established for the first time close association of Q. cyanescens with B. pendula. It is shown that the micromycete is regularly found not only in pollen samples, but also on surface and inside thyrsus, on surface of leaves and shoots of birch. However it is not isolated from other plant species within the investigated areas. Morphology, ultrastructure, frequency of the fungus, and also the phylogenetic analysis of isolated strains are provided in the article.
