Fine structure of ascosporogenesis in Nematospora coryli Peglion, a pathogenic yeast.
Observations with the electron microscope of the early stages of ascospore formation in Nematospora coryli Peglion reveal the following sequence of events. Partial dissociation of the nuclear membrane is followed by the appearance of unit membranes. Each unit membrane gives rise to two pairs of double membranes delimiting the ascospores from the epiplasm of the ascus. Enlarged mitochondria which have a granular matrix and limited cristae development are also regularly seen.
