Mycobiota of the snow cover of the territory of Samaracity

The article presents a characterization of mycobiota of the formed snow cover in Samara in 2013 and 2014. In the snow cover of suburb, uncontaminated areas of coastal parks Strukovsky and Zagorodnyi micromycetes were detected in the form of single colonies, or were not detected at all. Increase of microscopic fungi in the snow cover of the city (42 CFU/ml) was observed on the territories bordering highways, streams of people, that is due to the horizontal transfer of air masses. The composition of dominant micromycetes of the snow cover (a measure of occurrence was greater than 60 %) in 2013 and 2014 varied considerably and depended on the climatic conditions of the previous warm period of the year and the strength of the current winter frosts. Subdominant (incidence below 11 %), of the snow cover in winter periods studied were similar and were the fungi of the genus Alternaria, constantly prevailing in mycobiota air environment of the city in the summer-autumn period.
