Epifoliar fungi are one of the significant fungal groups typically living on the surface of leaves. They are usually recorded as saprobes, obligate parasites and commensals and are widely distributed in tropical and subtropical regions. Numerous genera within this group remain inadequately understood, primarily attributed to limited taxonomic knowledge and insufficient molecular data. Furthermore, the taxonomic delineation of epifoliar fungi remained uncertain, with scattered and literature-based data often intermixed with other follicolous fungi. Herein, a comprehensive taxonomic monograph of 124 genera in (32) Asterinales, (18) Capnodiales, (15) Chaetothyriales, (8) Meliolales, (8) Micropeltidales, (10) Microthyriales, (32) Parmulariales and (1) Zeloasperisporiales was provided re-describing with illustrations and line drawings. Notes on ecological and economic importance of the families are also provided. Representatives type herbarium materials of Campoa pulcherrima, Cycloschizon brachylaenae, Ferrarisia philippina, Hysterostomella guaranitica, Palawaniella orbiculata and Pseudolembosia orbicularis of Parmulariaceae were re-examined and provided updated illustrations with descriptions. A backbone phylogenetic tree and divergence estimation analysis for epifoliar fungi based on LSU and 5.8s ITS sequence data are provided.

叶表真菌是通常生活在叶子表面的重要真菌类群之一。它们通常被记录为腐生物、专性寄生虫和共生体，广泛分布于热带和亚热带地区。该类群中的许多属仍未得到充分了解，这主要归因于分类学知识有限和分子数据不足。此外，叶表真菌的分类学划分仍然不确定，分散的和基于文献的数据经常与其他毛囊真菌混合在一起。本文是 (32) Asterinales、(18) Capnodiales、(15) Chaetothyriales、(8) Meliolales、(8) Micropeltidales、(10) 124 属的综合分类专着提供了Microthyriales、(32) Parmulariales和 (1) Zeloasperisporiales 的重新描述，并配有插图和线条图。还提供了有关家庭的生态和经济重要性的注释。重新审查了Campoa pulcherrima、Cycloschizon brachylaenae、Ferrariasia philippina、Hysterostomella guaranitica、Palawaniella orbiculata和Parmulariaceae 的Pseudolembosia orbillaryis的代表性植物标本，并提供了更新的插图和描述。提供了基于 LSU 和 5.8s ITS 序列数据的叶表真菌主干系统发育树和分歧估计分析。
