Cytospora species are the most serious and widespread pathogens associated with canker disease on multiple plants. In this study, three species, i.e., Cytospora sophoricola, C. chrysosperma, and C. sophorae, which were isolated from Sophora in China, are described and illustrated based on their morphological characteristics and phylogenetic analyses. Cytospora sophoricola was distinguished clearly by its larger disc, multiple ostioles, cystic and multiple locules, and specific cultural characteristics, i.e., protruding fruiting bodies. Maximum parsimony and maximum likelihood analysis showed that it did not cluster with any known species of Cytospora, so it is described as a new species. Cytospora sophorae is a previously reported species from Sophora, which is redescribed based on new isolates and additional observations. Another species was identified as C. chrysosperma, which is reported for the first time on Sophora, so Papilionaceae is shown to be a new host family for C. chrysosperma. The morphological affinities of these species with related taxa are discussed, while the phylogenetic relationships of these species with other fungus in the genus Cytospora were elucidated based on their internal transcribed spacer (ITS) rRNA region sequences.
