The fertility status of soil depends not only on its chemical and physical composition but also depends of the occurrence of micro-organisms. During the course of study an extensive survey of area of forest of Achanakmar Bilaspur District (Chhattisgarh) was made to investigate the total microbial flora in relation to the seasonal trends in the forest appearance. Forty one fungal species were recorded from Achankmar forest of Bilaspur District of Chhattisgarh state. The fungi from these soil samples were isolated in season I (June – July) and in season II (November – December). Both seasons different species belongs to various groups viz; Ascomycotina, Zygomycotina and Deuteromycotina were identified with the help of relevant literatures. Dominance of Penicillium and Aspergillus were also recorded from both seasons. The diversity indices of forest soil fungi over the two seasons were 3.061, 2.861 (Shannon- Weinner), 0.9011, 0.9032 (Simpson index) and 16.72, 14.92 (Fishers’s alpha), respectively. The soil nutrients were also analyzed . The macro nutrients such as N, P, K content were rich in after the raining season and organic content of natural soil was also increased.
