On The Morphology of A Rare Coccoid Cyanoprocaryote, Chamaecalyx Swirenkoi, Chroococcales from India

Chamaecalyx (Komárek and Anagnostidis 1986) has been described in detail for the first time from freshwater cemented tanks of Allahabad, India. Studies based on the material collected from many cemented water tanks continuously for two years, revealed that, its growth was most common in those tanks which were located in shady places. This genus is distinguished on the basis of first horizontal division of sessile cells and formation of exocytes from the upper cell. Various stages of exocyte formation and proliferation of stalk cells are recorded. Occasionally repeated transverse divisions of a parent cell may result into a linear row of cells which look similar to the stages of the genus Stichosiphon or due to repeated divisions throughout the cell, the appearance of stalk cell is obscured and then it becomes quite comparable to the genus Cyanocystis.
