Abstract
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.
