Abstract

Species of Gnomoniaceae are commonly associated with leaf spot diseases of a wide range of plant hosts worldwide. During our investigation of fungi associated with tree diseases in China, several gnomoniaceous isolates were recovered from symptomatic branches and leaves on different woody plants in the Fagaceae, Pinaceae, and Salicaceae families. These isolates were studied by applying a polyphasic approach including morphological, cultural data, and phylogenetic analyses of partial ITS, LSU, , and gene sequences. As a result, three species were identified with characters fitting into the family Gnomoniaceae. One of these species is described herein as , characterized by developed pseudostromata and ascospores with obvious hyaline sheath; is illustrated showing sympodially branched conidiophore, oval or fusiform conidia; and one known species, . The current study improves the understanding of gnomoniaceous species causing diebacks and leaf spot on ecological and economic forest trees.
