Popis:	In this paper we present an ultrastructural study of spore formation in aerial vs. substrate mycelia of Streptomyces carpinensis. Both mycelia initiated spore formation at nearly the same time of colony development but exhibited different patterns of spatial localization of sporulation: spore formation took place throughout the aerial mycelium whereas in the substrate mycelium was confined to a narrow zone at the bottom of the colony. The ultrastructural changes leading to spore formation, however, were quite similar in both mycelia, differing only with respect to the outer components of the sporal wall. Spores formed in the aerial mycelium were covered by a thin sheath whereas the spores formed in the substrate mycelium were covered by an amorphous electron-dense material.
