Re : Diplodia on malus
Hello Robin,
I suggest you look at Dothiorella spp.
Best wishes




Dothiorella was reduced to synonymy under Diplodia by Crous
& Palm (1999), who used a broad morphological concept for
Diplodia. Phillips et al. (2005) re-examined the type of Dothiorella
pyrenophora Sacc. (K 54912) and found that it differed from
Diplodia by having conidia that are brown and 1-septate early in
their development, while they are still attached to the conidiogenous
cells. . In Diplodia conidial darkening and septation takes place after
discharge from the conidiomata. Crous et al. (2006) re-examined
the types of both Diplodia and Dothiorella and confirmed these
morphological differences.
