Remarks (internal):Petrak (1952b) regarded A. macrospora as a Diplodina or a Stagonospora species, but Melnik (1971) preferred to include it as a subgeneric taxon of Ascochyta Lib. As interpreted by Sprague (1950) the genus is heterogeneous because species with enteroblastic phialidic conidiogenesis are included with A. macrospora which is holoblastic. Species to be removed are A. agropyri Sprague and A. minor Sprague. Later Melnik (1976) accepted the generic name for 8 species including A. macrospora and extended the range to include species on Ranunculaceae and Leguminosae as well as Gramineae.
