Fungi and fucoids: relationships in different natural regions // Asian Mycological Congress 2013 & 13th International Marine and Freshwater Mycology Symposium. Aug. 19-23, 2013. China National Convention Center (CNCC), Beijing, China. Abstract Book. — Beijing, China, 2013. — P. 69–69. Fucales are dominant macroalgae in marine coastal ecosystems of different natural regions. We studied fungal community associated with dominant fucoids in cold northern White and Barents Seas (Fucus spp. and Ascophyllum nodosum) and in the temperate Black Sea (Cystoseira barbata). Using cultivation on different media, 101 species of fungi belonging to 42 genera were isolated and identified from the northern seaweeds; and 43 species belonging to 24 genera were isolated from the Cystoseira thalli. Also numerous hyaline and dark mycelia sterillia were isolated. We demonstrated that examined microfungal communities include some species typical for the nearby ecosystems (terrestrial soils, marine bottom and water): Aspergillus and Penicillium in the Black Sea samples; Geomyces, Penicillium and Tolypocladium in the White and Barents Seas samples. All the examined fungal communities also contain some specific elements, such as non-sporulating forms, Acremonium- and Phialophora-like fungi, and some pleosporalean anamorphs. Some of these isolates may represent obligate marine species, either yet undescribed or described, but still unknown in the culture.
