We researched microscopic morphological characters of Streptomyces spec. No.254. This strain was isolated from soil in our laboratory. The morphological characters are considerably different from the three strains reported in preceeding papers. On the CZAPEK-DOX agar and CB series media agar, the aerial mycelia are well developed, powderly or a little cottony, and brownish pink. The aerial mycelia are branched monopodially or in cluster and have many long straight or slightly bent hyphae. The terminal filaments are long straight or long wavy and the ends of them often give rise to spirals, especially on CB-III agar. The forms of spirals are flat and irregular, and the curvature is dextrorse or sinistrorse, compact, 1〜5 turns, 3.2〜9.6μ (occasionally to 12μ) in diameter. The aerial hyphae have a diameter of 0.8〜1.2μ, and no septa. The oidiospores are oval or short rod-shaped, 0.8〜1.2μ×1.0〜2.4μ.
