Soil microfungi in two post-mining chronosequences with different vegetation types

Soil microfungi were studied in the Sokolov (Czech Republic) post-mining dumps afforested with Alnus glutinosa and in the Lusatian (Germany) post-mining dumps afforested with Pinus sylvestris or P. nigra. Microfungi were isolated using the soil dilution plate method. Soil microfungi communities of two chronosequences were compared by species composition, frequency of species occurrence, and colony forming units of fungi (CFU-counts). Differences in species occurrence were determined. More species of entomopathogenic microfungi were found from the Sokolov post-mining area in comparison with the Cottbus post-mining area. Absidia glauca, A. cylindrospora, Penicillium glabrum, and P. janthinellum were the most frequently isolated species from the Cottbus post-mining area, while A. glauca, Geomyces pannorum, and Trichoderma koningii predominated at the Sokolov post-mining area.
