Cyanobacterial strain PS4G was isolated from seepage soil sampled at Pachmarhi, Madhya Pradesh, India, and was characterized using a polyphasic approach. The results of morphological analysis showed that strain PS4G had unique morphological characteristics which were not observed in the other described species of the genus Fortiea . In the 16S rRNA gene phylogenetic analysis inferred using Bayesian inference, maximum-likelihood and neighbour-joining methods, strain PS4G clustered within the clade consisting of the members of the genus Fortiea . Furthermore, in the secondary structure analysis using the D1–D1′ helix and BoxB regions of 16S–23S ITS, strain PS4G showed marked differences in comparison with other members of the genus Fortiea . Overall, the morphological, phylogenetic and folded 16S–23S ITS secondary structure examination indicated that strain PS4G represents a novel species of the genus Fortiea . In accordance with the International Code of Nomenclature of Algae, Fungi and Plants we describe a novel species of Fortiea with the name Fortiea necridiiformans sp. nov.
