We studied the morphological characteristics of Streptomyces spec. No.477.This strain was isolated from soil in our laboratory. In early stage of development the morphological characteristics are similar to those of Streptomyces spec. No.240 reported in preceeding paper V, namely, long straight aerial filaments are projected outward radially, branched in monopodial or bifurcate forms and they do not break into oidiospores. But, when the long straigth aerial filaments give rise to short side branches, the latter branch off in various degrees, though the short side branches of No. 240 do not branch. The terminal filaments of the short side branches develop to sinistrorse, compact spirals breaking into oidiospores. The branching systems of the short side branches are similar to those of S. coelicolor reported in III, but the forms of spirals to those of No.240.The aerial hyphae have a diameter of 0.7〜1.4μ and no septa. The oidiospores are oval; 0.7〜1.3 by 1.0〜2.1μ.
