Mycelial Fungi in the Bottom Sediments of the Black Sea

The material for the study of fungi from the bottom sediments of the Black Sea was collected on the voyages of the NIS "Professor Vodianitsky" (2013, 2016, 2017) at 64 stations in the depth range of 18–2080 m. Mushrooms were isolated by the culture method. 42 species of terrigenous fungi have been identified, the most represented families are Aspergillaceae and Plosoporaceae – 52.4% of the total number of species (17 and 5 species, respectively). A low abundance and frequency of occurrence of all species was recorded, Stachybotrys charlarum was most often noted (29.7%). 1–16 taxa were isolated from the samples for nutrient media, the number varied from 12–25363 (on average 2579 ± 4882) CFU/g of dry soil. The species composition and structure of mycocomplexes of sediments of various depths and different granulometric composition have been revealed. The highest indicators of species richness and abundance were recorded at depths of
