Endosporulating cyanobacterium Sphaerocongregus is reported for the first time from the cherty hand of the Lower Bhander Limestone Formation. Bhander Group exposed around Narsingharh in Damoh District, Madhya Pradesh. Individual colonies are globose and contain closely packed globular cells. The cells get arranged in the form of a loose colony after the dissolution of the encircling organic sheath. Globular colonies and the encircled cells can be distinctly discriminated into two distinct groups due to their distinct sizes. Globular colonies are clumped together to form either globose mass or linear chain. It is suggested that endosporulation of the algae was due to stressed habitat.
