基　　金：This project was funded by the National Science Foundation Partnerships for Enhancing Expertise in Taxonomy(NSF 03-28364).Additional funding for field work by DMW was received through Rutgers University,New Brunswick,NJ,from the C.Reed Funk Student Award by the Department of Plant Biology and Pathology,also the Backus Award and Everett Lutrell Mentor Student Travel Award from the Mycological Society of America.DMW also thanks Jo Anne Crouch and Adam Bazinet for assistance with data analyses,Kentaro Hosaka,Shinobu Inoue,Takao Kobayashi,Tsuyoshi Hosoya,Yousuke Degawa for hosting a collecting trip to Japan and Yuuri Hirooka for coordinating the visit,Christian Feuillet and Drew Minnis for discussions about nomenclature,Ryan Vo and Tunesha Phipps for technical assistance,and Larissa Vasilyeva,Alain Gardiennet,Yannick Mourgues,Marc Chovillon,Jacques Fornier,and Mikhail Sogonov for collection of fresh specimens for examination.

摘　　要：Species of Ophiognomonia are leaf-inhabiting endophytes,pathogens,and saprobes that infect plants in the families Betulaceae,Fagaceae,Juglandaceae,Lauraceae,Malvaceae,Platanaceae,Rosaceae,Salicaceae,and Sapindaceae.Based on extensive collecting,this speciesrich genus is now known to have a world wide distribution in primarily temperate areas,although some species are known from the subtropics.Analyses of DNA sequences from three markers including guanine nucleotide-binding protein subunit beta-like protein(MS204),translation elongation factor 1α(tef-1α),and the ITS region including ITS1,5.8 S rDNA and ITS2 regions(ITS)were used to define phylogenetic species in Ophiognomonia.Host plant association correlated with these species.Twenty-five new species of Ophiognomonia and two new combinations are proposed with descriptions and illustrations.In addition,descriptions and illustrations are provided for 12 other species of Ophiognomonia.A key is provided to the 45 currently accepted species of Ophiognomonia.The disposition of additional names in Ophiognomonia is also discussed.
