Species of Cryphonectria include some of the world's most important and devastating tree pathogens. Largely through the application of DNA sequence phylogenies, the taxonomy of these fungi has undergone major changes in recent years. Cryphonectria, including the chestnut blight pathogen Cryphonectria parasitica, has been restricted to species that have semi-immersed stromata, orange and pulvinate conidiomata, and one-septate ascospores. Other species of Cryphonectria with different morphological characteristics have been transferred to new genera that are strongly supported by phylogenetic data. This review represents a summary of the taxonomic changes to species of Cryphonectria sensu lato, and we discuss the impact that these changes might have on the understanding of their ecology, pathology and worldwide distribution.
隐孢壳菌属的一些物种是世界上最重要且极具破坏力的树木病原体。近年来，主要通过DNA序列系统发育学的应用，这些真菌的分类学发生了重大变化。隐孢壳菌属，包括栗疫病菌寄生隐孢壳菌，已被限定为具有半埋生子座、橙色且垫状分生孢子器以及具一个隔膜的子囊孢子的物种。其他具有不同形态特征的隐孢壳菌属物种已被转移到新的属中，这些新属得到了系统发育数据的有力支持。本综述总结了广义隐孢壳菌属物种的分类学变化，并讨论了这些变化可能对理解其生态学、病理学和全球分布产生的影响。
