abstract = {Since 2010, an unknown fungus in the Gnomoniaceae has been found on overwintered leaves and petioles of Styrax obassia (Styracaceae) in Japan. This fungus is characterized by dark brown immersed or partially erumpent ascomata with long necks and fusiform to obovoid asci each with an acute or long tapering stipe. Each ascus bears eight fusiform to filiform ascospores. Phylogenetic analyses based on the markers LSU, rpb2, and tef-1α indicated that this is a new monotypic genus in the Gnomoniaceae (Diaporthales). We thus propose Tenuignomonia styracis gen. et sp. nov. Members of the Gnomoniaceae are commonly isolated as endophytes, saprobes, and plant pathogens from a broad diversity of herbaceous, shade tree, and agriculturally significant plants. We thus carried out a pathogenicity test to determine if T. styracis is the causative agent of leaf blotch on S. obassia. One week after inoculation, this fungus produced small necrotic spots on the leaves and petioles, and all leaves having necrotic spots were abscised in a short time. We thus confirmed that this fungus has weak pathogenicity on S. obassia. This new species may promote early defoliation of S. obassia during the fall.}
