1. DNA homology was studied in 12 Chlorella species. The DNA of 88 strains was hybridized with 3H-labelled DNA from C.fusca var. vacuolata 2tl-8b and from C. vulgaris 2tl-8m. The results indicate that the genus Chlorella is a heterogenous taxon which consists of several groups of species. 2. The "C.
16 strains of the genus Prototheca do not produce extracellular amylolytic enzymes. The base composition of their DNA shows rather continuous values from 62 ~ to 78 ~o GC (guanine + cytosine). Their assignment to four species and their possible relationship with Chlorella protothecoides are discusse
