The Greater Mekong Subregion (GMS) is known as a diverse geographic landscape and one of the richest biodiversity hotspots in the world with a high fungal diversity. Collections were carried out in terrestrial habitats to determine the diversity of woody litter fungi in the GMS, with an emphasis on northern Thailand and the Yunnan Province of China. Morphological characteristics and multigene phylogenetic analyses of combined SSU, LSU, ITS, and <i>tef</i>1-α supported the placement of the new isolates in the family <i>Didymosphaeriaceae</i>. The phylogenetic affinities of our isolates are illustrated through maximum likelihood and Bayesian inference analyses. Seven species of woody litter fungi were identified, comprising a new monotypic genus, <i>Septofusispora</i>; five novel species (<i>Chromolaenicola sapindi</i>, <i>Dictyoarthrinium thailandicum</i>, <i>Karstenula lancangensis</i>, <i>Septofusispora thailandica</i>, and <i>Spegazzinia jinghaensis</i>); and new host records of two species (<i>Austropleospora archidendri</i>, and <i>Montagnula donacina</i>). Furthermore, this study provides a synopsis of the <i>Montagnula</i> aff. <i>donacina</i> species based on their morphological characteristics, which can be useful in the species-level identifications in this genus.
