In this study, twelve terrestrial hysteriaceous saprobic fungi growing on different pieces of dead wood were collected from Yunnan Province, China. All hysteriaceous strains isolated in this study tallied with the general characteristics associated with <i>Rhytidhysteron</i>. Detailed morphological characteristics and combined multigene phylogeny of LSU, ITS, SSU, and <i>TEF</i> showed that the twelve hysteriaceous fungi strains represent four distinct new species, and seven new host or geographical records of <i>Rhytidhysteron</i>. Based on morphological and phylogenetic evidence, the four new species (<i>Rhytidhysteron bannaense</i> sp. nov., <i>R. coffeae</i> sp. nov., <i>R. mengziense</i> sp. nov., and <i>R. yunnanense</i> sp. nov.) expand the number of species of <i>Rhytidhysteron</i> from thirty-three to thirty-seven, while seven new geographical records expand the records of <i>Rhytidhysteron</i> in China from six to thirteen. In addition, 10 new <i>Rhytidhysteron</i> host records are reported for the first time, thus expanding the known hosts for <i>Rhytidhysteron</i> from 52 to 62. Full descriptions, images of the morphology, and phylogenetic analyses to show the position of the <i>Rhytidhysteron</i> taxa are provided. In addition, the present study summarizes the main morphological characteristics, host associations, and locations of this genus.
