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.
