Although , and are known as causal agents of anthracnose of soybean, and , respectively, their taxonomy remains unresolved. In preliminary analyses based on ITS, strains of these species appear basal in phylogenies, clustering close to , and other recently described species from tropical or subtropical regions. Phylogenetic analyses (ITS, , ) of 102 strains previously identified as , and as well as other related strains from different culture collections and studies placed these taxa in three species complexes, and distinguished at least 24 species, including 11 new species. In this study, , and were epitypified and their taxonomy resolved, while was proposed as a new name for . Furthermore, a sexual morph was observed for , while , and were reported from new hosts or countries. Regarding their conidial morphology, species in the and species complexes are reminiscent of or s. lat., and were likely to be confused with them in the past.
虽然 、 和 分别被认为是大豆炭疽病的致病因子,但它们的分类学仍未解决。在基于ITS的初步分析中,这些物种的菌株在 系统发育中似乎处于基部,聚集在 、 以及其他最近描述的来自热带或亚热带地区的物种附近。对102株先前鉴定为 、 和 的菌株以及来自不同培养物保藏中心和研究的其他相关菌株进行的系统发育分析(ITS、 、 )将这些分类群置于三个物种复合体中,并区分出至少24个物种,包括11个新物种。在本研究中, 、 和 被指定后选模式,其分类学得到解决,同时 被提议作为 的新名称。此外,观察到 有有性型,而 、 和 是从新宿主或新国家报道的。关于它们的分生孢子形态, 和 物种复合体中的物种让人联想到 或广义的 ,并且过去可能与它们混淆。
