Ophiobolus is a large genus of Phaeosphaeriaceae comprising more than 350 possible species, most of which are saprobes on herbaceous plants in Europe and North America. Ophiobolus species are polyphyletic and the type of Ophiobolus is not represented in GenBank. Therefore, an increased taxon sampling of ophiobolus-like taxa and epitypification of the type species, O. disseminans is reported. Multigene phylogenetic analyses of combined LSU, SSU, TEF1-α and ITS sequence data position O. disseminans in a sister clade with O. ponticus and several Entodesmium species in Phaeosphaeriaceae with high support. Therefore, Entodesmium is synonymized under Ophiobolus. Premilcurensis with it type species, P. senecionis also clusters within the Ophiobolus clade and is synonymized under Ophiobolus. Ophiobolus rossicus sp. nov. is introduced and a reference specimen is designated for O. ponticus. Other ophiobolus-like taxa (Ophiobolus sensu lato) can be distinguished as three main groups, which are introduced as new genera. Ophiobolopsis is introduced to accommodate the new species, Ophiobolopsis italica. The new genus Paraophiobolus is introduced to accommodate P. arundinis sp. nov. and P. plantaginis comb. nov. This genus is characterized by hyaline to pale yellowish ascospores, some green-yellowish at maturity, with a swollen cell, terminal appendages and ascospores not separating into part spores. Pseudoophiobolus gen. nov. is introduced to accommodate six new species and two new combinations, viz. Ps. achilleae, Ps. erythrosporus, Ps. galii, Ps. italicus, Ps. mathieui, Ps. rosae, Ps. subhyalinisporus and Ps. urticicola. Pseudoophiobolus is characterized by subhyaline to pale yellowish or yellowish ascospores, with a swollen cell, lack of terminal appendages and ascospores that do not separate into part spores and is related to Nodulosphaeria. An updated tree for Phaeosphaeriaceae based on multigene analysis is also provided.

朝着蛇怪和类蛇怪类群的自然分类；介绍了三种新的麦兜铃属，副竹节虫和假拟竹节虫属（Poleosporales）

Ophiobolus是一个大属Phaeosphaeriaceae包括超过350种可能，其中大部分是在欧洲和北美的草本植物saprobes。Ophiobolus物种是复系的类型和Ophiobolus未在GenBank中表示。因此，据报道，增加了类玻璃质类群的分类群采样和该类型种（O. disseminans）的表型化。合并的LSU，SSU，TEF1-α的多基因系统发育分析，它的序列数据位置O. disseminans的姊妹进化枝与O. ponticus和几个Entodesmium种Phaeosphaeriaceae具有高的支持。所以，Entodesmium在Ophiobolus下是同义词。Premilcurensis与它键入物种，P. senecionis也是内簇Ophiobolus进化枝和下异名Ophiobolus。蛇形麦冬菌 十一月 介绍了一个参考标本，并指定了O. ponticus。其他类似ophiobolus的类群（Ophiobolus sensu lato）可以分为三个主要类别，它们作为新属被引入。Ophiobolopsis介绍，以适应新的物种，Ophiobolopsis谷子。引入了新属Paraophiobolus以适应P. arundinis sp。十一月 和P. plantaginis梳子。十一月 该属的特征是透明到淡黄色的子囊孢子，成熟时有些绿色-黄色，细胞肿胀，末端附肢和子囊孢子不分离成部分孢子。假蛇麻杆菌属。十一月 被引入以容纳六个新物种和两个新组合，即。附言 achilleae，诗篇。erythrosporus，诗篇。GAL-II，诗篇。italicus，诗篇。mathieui，诗篇。蔷薇，诗篇。亚透明质酸和Ps。荨麻疹。假oph虫其特征是亚透明膜下至淡黄色或淡黄色的子囊孢子，具有肿胀的细胞，没有末端附肢和不分离为部分孢子的子囊孢子，与结节菌有关。还提供了基于多基因分析的更新的球菌科树。
