According to V. Shubin, 421 species of cap fungi grow in the district. Edible mushrooms are represented by 208, poisonous - by 22 and mushrooms with medicinal properties - by 43 species. 18 species of fungi are classified as rare and vulnerable. Biological resources of edible mushrooms in accessible young tree stands on dry soils were calculated (tab.). Up to 1780 ton of mushrooms can be harvested in an average-productivity year. These very rough calculations prove that much of the rich mushroom resources in the district remain unutilized. Fifteen so far not widely known species of edible mushrooms have been recommended for harvesting in the first place.
