ABSTRACT=<p>Yunnan, located in southwestern China, is known for its high fungal diversity, and many of which are endemic to the region. As part of our ongoing studies on fungi in Yunnan, we introduce two new genera in <italic>Phaeothecoidiellaceae</italic> (<italic>Mycosphaerellales</italic>), to accommodate one <italic>Repetophragma</italic>-like and another <italic>Stomiopeltis</italic>-like taxa. <italic>Pseudorepetophragma</italic> gen. nov. is introduced herein as a monotypic genus to accommodate <italic>P. zygopetali</italic> comb. nov.(≡ <italic>Repetophragma zygopetali</italic>), whereas <italic>Pseudostomiopeltis</italic> gen. nov. is introduced to accommodate <italic>Ps. xishuangbannaensis</italic> gen. et sp. nov. and <italic>Ps. phyllanthi</italic> comb. nov.(≡ <italic>Stomiopeltis phyllanthi</italic>), based on a new collection from Yunnan. In addition, <italic>Stomiopeltis sinensis</italic> is transferred to <italic>Exopassalora</italic> as <italic>E. sinensis</italic> comb. nov. due to its phylogenetic affinity and grouped with <italic>E. zambiae</italic>, the generic type of <italic>Exopassalora</italic>. This study provides new insights into the biodiversity of fungal species in this region and adds to our understanding of their ecological roles, as well as the resolution to ambiguous taxa in <italic>Phaeothecoidiellaceae</italic>.</p>
