Abstract: This paper deals with the morphology and life cycle of a new species of Dysmorphococcus oblatus Yu et Wei (Phacotaceae, Volvocales) from Africa. The alga seems to be morphologically rather distinct from the other members (lorica, protoplast and number of pyrenoid). Moreover, a comparison is made of overall morphological and reproductive characteristics of the present taxon with the other 8 known species of this genus. The cultural experiment of the life cycle of this alga reveals certain attributes unrecorded for early des- cribed species of this genus. The alga is homothallic, and heterogametic and sexual reproduc-tion produces 32-64 male gametes and 2 female gametes.Decontaminated thianthrene disproportion.
