A new species, Ramularia hydrangeicola, causing leaf spots was observed on Hydrangea serrata f. acuminata. Morphological characteristics and phylogenetic analyses support this fungus as a distinct new species. The new fungus is described, illustrated, and compared with R. hydrangeae, R. hydrangeae-macrophyllae, and R. philadelphi, three additional species on hosts of the Hydrangeaceae.
