Abstract

SUMMARY: The fine structure of the morphological events during sporulation in grown on chemically defined medium was studied in electron micrographs of thin sections. During vegetative growth the young hyphae were divided into long cells by cross-walls which formed in a way comparable to those in certain other Gram-positive bacteria. Sporulation was initiated by coiling of hyphal tips, which were then divided into spore-sized compartments by special cross-walls, the ‘sporulation septa’. These were laid down as double rings attached to the hyphal wall and extending centripetally. After completion of the septa the walls thickened uniformly and the individual spores began to round off. The new wall material on the long side of the spores appeared to be deposited underneath the old parent wall; the old cell wall probably formed part of the spore wall.
