Species diversity of entomogenous fungal flora of Mountains Dabie, Anhui
安徽大别台区虫生真菌区系的物种多样性研究

Based on study of species diversity, 50 species of entomogenous fungi belonging to 16 genera, 4 families and 4 orders were recorded in Dabie Mountains in western Anhui. At the family level, Clavicipitaceae, comprising 27 species, had the highest percentage, with 54% of the total species, while the family Hyphomycetaceae, comprising 15 species, accounted for 30%. The family Entomophthoraceae comprised 5 species (10%), and the smallest percentage was taken by the family Stilbellaceae, comprising 3 species (6%). Considering genera, the dominant genera were Cordyceps (27 species, 52% of the total), Paecilomyces (6 species, 12%), and Beauveria (3 species, 6%). These three genera covered 35 species, accounting for 70% of the total, while they amounted to 18.75% of the total genera. Akanthomyces and Zoophthora were oligotypic genera, both with two species. The rest were monotypic genera, comprising 68.75% of the total genera and 22% of the total species. The dominant species were Paecilomyces farinosus, P. tenuipes, C. nutans, B. bassiana, and Metarhizium anisopliae var. anisopliae. Therefore, the dominant genera and species were evident in this area. By categorization of modern distribution centers in terms of the present distribution patterns of taxa, species were grouped into Cosmopolitan (42.11%), Eurasian (10.53%), Subtropical to Tropical (5.26%), East Asian (7.89%), East Asian Papuan (5.26%), Sino Japanese (5.26%), and Endemic (23.68%). Overall, East Asian elements were characteristic of this region and local and Chinese endemic species were evident.
