Fungi are one of the most diverse groups of organisms with an estimated number of species in the range of 2–3 million. The higher-level ranking of fungi has been discussed in the framework of molecular phylogenetics since Hibbett et al., and the definition and the higher ranks (e.g., phyla) of the ‘true fungi’ have been revised in several subsequent publications. Rapid accumulation of novel genomic data and the advancements in phylogenetics now facilitate a robust and precise foundation for the higher-level classification within the kingdom. This study provides an updated classification of the kingdom Fungi, drawing upon a comprehensive phylogenomic analysis of Holomycota, with which we outline well-supported nodes of the fungal tree and explore more contentious groupings. We accept 19 phyla of Fungi, viz. Aphelidiomycota, Ascomycota, Basidiobolomycota, Basidiomycota, Blastocladiomycota, Calcarisporiellomycota, Chytridiomycota, Entomophthoromycota, Entorrhizomycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota, Sanchytriomycota, and Zoopagomycota. In the phylogenies, Caulochytriomycota resides in Chytridiomycota; thus, the former is regarded as a synonym of the latter, while Caulochytriomycetes is viewed as a class in Chytridiomycota. We provide a description of each phylum followed by its classes. A new subphylum, Sanchytriomycotina Karpov is introduced as the only subphylum in Sanchytriomycota. The subclass Pneumocystomycetidae Kirk et al. in Pneumocystomycetes, Ascomycota is invalid and thus validated. Placements of fossil fungi in phyla and classes are also discussed, providing examples.

真菌是最多样化的生物群之一，估计物种数量在 2-300 万之间。自 Hibbett 等人以来，一直在分子系统发育学的框架中讨论了真菌的更高级别排名，并且“真真菌”的定义和更高等级（例如，门）在随后的几篇出版物中进行了修订。新基因组数据的快速积累和系统发育学的进步现在为王国内的更高级别分类奠定了坚实而精确的基础。本研究利用对全菌门的全面系统发育分析，提供了真菌界的最新分类，通过该分析，我们概述了真菌树中得到充分支持的节点，并探索了更多有争议的分组。我们接受 19 个真菌门，即。无孢菌门、子囊菌门、担子菌门、担子菌门、芽生菌门、钙孢菌门、壶菌门、昆虫菌门、内托根菌门、球菌门、Kickxellomycota、单眼菌门、Mortierellomycota、Mucoromycota、Neocallimastigogocota、 Olpidiomycota、Rozellomycota、Sanchytriomycota 和 Zoopagomycota。在系统发育中，Caulochytriomycota 居住在 Chytridiomycota;因此，前者被视为后者的同义词，而 Caulochytriomycetes 被视为壶菌门中的一类。我们提供了每个门的描述，然后是它的类。 一个新的亚门 Sanchytriomycotina Karpov 被介绍为 Sanchytriomycota 中唯一的亚门。Pneumocystomycetes， Ascomycota 中的 Pneumocystomycetidae Kirk et al. 亚类是无效的，因此得到了验证。还讨论了化石真菌在门和类中的位置，并提供了示例。
