The genus Ceratocystis was established in 1890 and accommodates many important fungi. These include serious plant pathogens, significant insect symbionts and agents of timber degradation that result in substantial economic losses. Virtually since its type was described from sweet potatoes, the taxonomy of Ceratocystis has been confused and vigorously debated. In recent years, particulary during the last two decades, it has become very obvious that this genus includes a wide diversity of very different fungi. These have been roughly lumped together due to their similar morphological structures that have clearly evolved through convergent evolution linked to an insect-associated ecology. As has been true for many other groups of fungi, the emergence of DNA-based sequence data and associated phylogenetic inferences, have made it possible to robustly support very distinct boundaries defined by morphological characters and ecological differences. In this study, DNA-sequence data for three carefully selected gene regions (60S, LSU, MCM7) were generated for 79 species residing in the aggregate genus Ceratocystis sensu lato and these data were subjected to rigorous phylogenetic analyses. The results made it possible to distinguish seven major groups for which generic names have been chosen and descriptions either provided or emended. The emended genera included Ceratocystis sensu stricto, Chalaropsis, Endoconidiophora, Thielaviopsis, and Ambrosiella, while two new genera, Davidsoniella and Huntiella, were described. In total, 30 new combinations have been made. This major revision of the generic boundaries in the Ceratocystidaceae will simplify future treatments and work with an important group of fungi including distantly related species illogically aggregated under a single name.

毛囊藻属（Ceratocystis）成立于1890年，可容纳许多重要的真菌。其中包括严重的植物病原体，重要的昆虫共生体和木材降解剂，这些物质会造成重大的经济损失。实际上，由于它的类型是用地瓜描述的，所以是Ceratocystis的分类法。一直感到困惑和激烈辩论。近年来，尤其是在最近的二十年中，该属包括非常不同的真菌的多样性非常明显。由于它们相似的形态结构已通过与昆虫相关生态系统的趋同进化而明显演化，因此它们已被粗略地集中在一起。就像许多其他真菌一样，基于DNA的序列数据和相关的系统发育推断的出现，有可能强有力地支持由形态特征和生态差异定义的非常独特的边界。在这项研究中，生成了森森拉美氏囊藻的79个物种的三个精心选择的基因区域（60S，LSU，MCM7）的DNA序列数据。对这些数据进行了严格的系统发育分析。结果使得可以区分七个主要类别，为其选择了通用名称，并提供或修改了描述。修订后的属包括严格意义上的Ceratocystis sensu，查拉罗普氏菌，Endoconidiophora，Thielaviopsis和Ambrosiella，同时描述了两个新属，Davidsoniella和Huntiella。总共进行了30种新组合。角藻科的通用边界的这一重大修订 将简化未来的治疗方法，并与重要的真菌类一起工作，包括不合逻辑地以单一名称聚集的远缘物种。
