abstract = {Erysiphe species (powdery mildews) on Corylus and Ostrya spp. (Betulaceae subfam.
Coryloideae) in Asia and North America are widespread pathogens on these economically
and ecologically valuable nut crops. An improved understanding of their phylogeny and
taxonomy is of ecological and applied importance. Phylogenetic analyses and
morphological re-examinations conducted in this study revealed a higher degree of
diversity and cryptic speciation than reflected in earlier species concepts. North American
collections on C. cornuta, which were previously assigned to E. corylacearum, proved to
constitute a species of its own, and are herein introduced as E. cornutae sp. nov. Two
additional North American species, E. coryli-americanae sp. nov. and E. ostryae sp. nov.,
have been detected on C. americana and O. virginiana, and are described. They are
morphologically similar to E. cornutae, but genetically distinct. Based on phylogenetic
analyses, E. corylacearum is an Asian species confined to various Asian Corylus species.
Sequence data retrieved from Japanese type material of E. corylicola revealed that this
species clusters with sequences from E. elevata on Catalpa species, distant from all other
Erysiphe species on Corylus. Hence, past taxonomic applications of this name are
obsolete. Morphologically similar specimens on C. sieboldiana, which were previously
assigned to E. corylicola, form a distinct, distant clade. The species involved is described
herein as E. pseudocorylacearum sp. nov. Additionally, an unusual, probably accidental
infection of C. sieboldiana in Japan by E. syrinae has been shown by means of sequence
data. The phylogeny and taxonomy of Erysiphe species belonging to the Corylioideae are
discussed in detail and a key to the species concerned is provided.}
