摘要：

The reproductive organs of one of the pathogens responsible for the septoria diseases of wheat were studied rom cultures. There are two types of pycnidia for the asexual stage (one belongs to Septoria nodorum Berk. (=Stagonospora nodorum (Berk.) Castellani & Germano); the other is microconidial) and pseudothecia for the teleomorph: Phaeosphaeria nodorum (E. Muller) Hedjaroude (=Leptosphaeria nodorum E. Muller). The latter are differentiated from glomerular primordia, and their development is typical of an ascolocular pyrenomycete, with a perilocular layer generating descending pseudoparaphyses and periphyses lining the ostiolar cavity. The asci, with a "Jack-in-the-box" dehiscence, are bitunicate.
