Species in <i>Microdochium</i>, potential agents of biocontrol, have often been reported as plant pathogens, occasionally as endophytes and fungicolous fungi. Combining multiple molecular markers (ITS rDNA, LSU rDNA, TUB2 and RPB2) with morphological characteristics, this study proposes three new species in the genus <i>Microdochium</i> represented by seven strains from the plant hosts <i>Miscanthus sinensis</i> and <i>Phragmites australis</i> in Hainan Island, China. These three species, <i>Microdochium miscanthi</i> sp. Nov., <i>M. sinens</i><i>e</i> sp. Nov. and <i>M. hainanense</i> sp. Nov., are described with MycoBank number, etymology, typification, morphological features and illustrations, as well as placement on molecular phylogenetic trees. Their affinity with morphologically allied and molecularly closely related species are also analyzed. For facilitating identification, an updated key to the species of <i>Microdochium</i> is provided herein.
