Although the conidia of these species appear superficially different because of the long appendages on those of E. mespili, developmental similarities to the conidia of M. rosae and M. fragariae have been noted (Farr 1993, Sutton 1980) as well as the morphologically similar sexual morphs. In addition, ITS sequences indicate that the type species of Diplocarpon, Entomosporium, and Marssonina may be congeneric. Over 100 names have been placed in Marssonina, but this genus has not been well defined and many of these names represent unrelated species. We recommend the protection of Diplocarpon.
