Technical Abstract: As a continuation of an ongoing study of DNA relatedness among red-spored streptomycetes, the homology between the four species comprising the Streptomyces fulvissimus phenotypic cluster (S. fulvissimus, S. aureoverticillatus, S. longispororuber, and S. spectabilis) and the four species comprising the Streptomyces griseoviridis phenotypic cluster (S. griseoviridis, S. chryseus, S. daghestonicus, and S. murinus) was measured spectrophotometrically from C0t0.5 determinations. All strains were also compared to 12 strains representing previously determined DNA relatedness clusters in the Streptomyces lavendulae phenotypic cluster, including the type strain NRRL B-1230. The strains segregated into 13 cluster groups at DNA relatedness greater than 70%, including 8 single member clusters. S. griseoviridis and S. daghestonicus were synonymous, as were S. chryseus and S. longispororuber. S. spectablis exhibited species-level homology with strain NRRL B-2402, which had been deposited in the collection as S. lavendulae and S. aureoverticillatus exhibited significant DNA relatedness to S. flavotricini. None of the strains from the S. fulvissimus or S. griseoviridis clusters exhibited significant homology to the type strain of S. lavendulae.
