真菌系统学是生物学研究的重要组成部分，特别是在其生态和经济意义方面。然而，多形性和非多形性无性型的分类是不确定的，这可以归因于双重命名/分类系统的历史实践。本文回顾了双重分类系统的历史建立和局限性，并叙述了DNA序列数据在发展基于进化关系的分类系统中的可能用途。双重分类制度是一个失败的假设。DNA序列数据现在被常规地用于连接无性型与全形，并提供无性型与未知teleomorphs的系统发育位置。新兴的系统发育和命名的情况下，在Botryosphaeriales，Chaetosphaeriales，禾谷镰刀菌，pestalotiopsis样无性型，和Mycosphaerella复杂的说明潜在的命名和分类的复杂性与双重命名/分类系统。真菌学界有一项艰巨的任务，即开发一个分类系统，以满足不同分类用户的需求。分子特征和工具无疑是真菌系统学研究中不可缺少的一部分。
Fungal systematics is an essential part of biological research especially in the context of its ecological and economic implications. The classification of pleomorphic and non-pleomorphic anamorphs, however, is unsettled, which can be attributed to the historical practice of the dual nomenclature/classification system. This paper reviews the historical establishment and limitations of the dual system of classification, and narrates the possible utilities of DNA sequence-data in developing a system of classification based on evolutionary relationships. The dual classification system is a failed hypothesis. DNA sequence-data are now routinely used to link anamorphs with a holomorph and to provide phylogenetic placement for anamorphs with unknown teleomorphs. Emerging phylogenetic and nomenclatural scenarios in the Botryosphaeriales, Chaetosphaeriales, Fusarium graminearum, pestalotiopsis-like anamorphs, and the Mycosphaerella complex are illustrated to indicate potential nomenclatural and taxonomic complexities associated with the dual nomenclature/classification system. The mycological community has a daunting task of developing a system of classification that fulfils the needs of diverse taxonomic users. Molecular characters and tools are, undoubtedly, an indispensable part of fungal systematics.
