Interpretive Summary: Recent changes in the rules by which fungi are named have caused problems in knowing what to call some plant pathogenic fungi. Numerous papers have been published with recommendations on which name should be used for major groups of plant pathogens but some individual species have been overlooked. In this paper all known information is used to decide the correct name for a fungal species causing a disease of apples, Diplocarpon coronariae. This work is significant because it will allow correct identification of this important disease-causing fungus. These results will be used by plant pathologists, horticulturists, and forestry professionals as well as plant quarantine officials who need accurate scientific names to communicate about fungi.

Technical Abstract: Apple blotch is a severe disease of apples that was initially described from North America and has caused enormous losses to apple production in Asia. It is also becoming more problematic in Europe. Known primarily in the asexual morph, the causal fungus has long been known as Marssonina coronariae (Ellis & Davis) Davis. The sexual morph was discovered and described as Diplocarpon mali Y. Harada & Sawamura and there seems to be no doubt that M. coronariae and D. mali both refer to the fungal species causing apple blotch. Several studies have confirmed that this species is congeneric with D. rosae, type of Diplocarpon. It has been recommended that Diplocarpon should be protected and used rather than Marssonina and after evaluating all of the known synonyms that have been applied to this species, the oldest epithet is Ascochyta coronaria 1903. Thus, the name Ascochyta coronaria should be placed in Diplocarpon as Diplocarpon coronariae (Ellis & Davis) Rossman & Wöhner. A nomenclator is provided.
