Fungi within the phylum Gigasporomycota were investigated in iron mines fields in Chhattisgarh. Chhattisgarh is located between 21.27°N 81.60°E. The fungi within this phylum form arbuscular mycorrhizal symbiosis with plant roots. Sampling of soil was carried out to a depth of 30 cm in the rhizosphere. Arbuscular mycorrhizal fungi were found at all 10 sampling sites in each field, at densities in between 0 to 03 spores per g dry weight of soil. Significant differences in spore densities were found between unmined, mined and dumped area of iron mines fields. Our study revealed that the upper half (0-15 cm) of the soil profiles had significantly more spores than the lower half (15-30 cm). Spores from ten sampling sites were identified from the indigenous soils. Almost 90% were shown to belong to the genus Gigaspora. The other genera found were Glomus and Sclerocystis.
