✦ Synopsis

DNA hybridization techniques showed Chlorella fusca vat. vacuolata and C. kessleri to be homogeneous species with DNA homologies of 90-100%. C. fusca var. fusca and vat. rubescens, however, have only about 15% DNA homology with C. fusca var. vacuolata and should no longer be regarded as varieties. A good correlation was found so far between biochemical and physiological characters used in the taxonomy of Chlorella and DNA relatedness. Mutant strains of Chlorella were tested for DNA homologies to prove the reliability of the taxonomical interpretation.
