Collections of Bionectriaceae and Nectriaceae from Henan, Hubei and Guangdong provinces, China, were examined. Three new species, Neonectria confusa, N. shennongjiana and N. sinensis, are described and illustrated. Distinctions between the new species and their related taxa are discussed. Phylogenetic relationships among some Neonectria species are investigated based on analyses of nuclear ribosome DNA ITS1-5.8S-ITS2 and beta-tubulin partial sequences. Combined analyses of molecular and morphological data suggest that N. confusa and N. shennongjiana can be classified in Neonectria sensu stricto and N. sinensis in the N. mammoidea-Group. A key to the known species of Neonectria from China is provided.
对中国河南、湖北和广东等地的 Bionectriaceae 和 Nectriaceae 进行了收集和研究。描述并图示了三个新种，即混生拟盘多毛孢（Neonectria confusa）、神农拟盘多毛孢（N. shennongjiana）和中华拟盘多毛孢（N. sinensis）。讨论了新种与相关分类群之间的区别。基于核核糖体 DNA ITS1-5.8S-ITS2 和β-微管蛋白部分序列的分析，研究了一些 Neonectria 种之间的系统发育关系。分子和形态数据分析的综合结果表明，N. confusa 和 N. shennongjiana 可归入 Neonectria 属，而 N. sinensis 归入 N. mammoidea-Group。提供了中国已知 Neonectria 种的一个关键。
