Abstract
The paper reports a new algal found growing on Ceratophyllum leaves in a small pond near Lucknow. It possesses a heterotrichous vegetative organization, typical Coleochaeta-like bristles and an oogamous sexual reproduction. Antheridia are simple, unspecialized, formed from vegetative cells producing several antherozoids each. Oogonia are large, swollen, oval, slightly elongate structures possessing a prominent beak. One or more oospheres are formed in each oogonium and some sterile residual cytoplasm may be left unutilized during oogenesis. Sterile cortications around the oospore or fertilized oogonia are absent. The present plant is considered a new genus of the family Coleochaetaceae (Chlorophyceae) and named Awadhiella gen. nov.
