Freshwater algae can tolerate wide range of environmental stress and grow naturally in mixedcommunities. In the present study diversity of algae has been studied in some suburban waterbodies near Lucknow, which revealed the occurrence of 32 genera and 40 taxa under four phyla -Cyanophyta, Chlorophyta, Bacillariophyta and Euglenophyta. It is observed that heavyanthropogenic activities and low water level in late summer resulted in accumulation of pollutantswhich affected the algal species composition. The polluted water with high conductivity andtotal dissolved solids (TDS) showed the dominance of Cyanophyta and Bacillariophyta whereasmost of Chlorophyta and few Bacillariophyta were found in less polluted water with lowconductivity and TDS. Taxa Centritractus belonophorus belonging to Xanthophyta is beingreported for the first time from Uttar Pradesh. The study also recorded for the first time severalalgal taxa from these water bodies of Lucknow.
