Additions to Dictyosporiaceae: comb. et gen. nov., Two New Species and Four New Host Records from Medicinal Plants in Southwestern China.

Medicinal plants serve as vital resources for preventing and treating diseases, with their flowers, fruits, leaves, roots, or entire plants being utilized in the pharmaceutical industry or as direct therapeutic agents. During our investigation of microfungi associated with medicinal plants in Guizhou and Sichuan Provinces, China, several asexual and sexual fungal morphs were collected. Multi-locus phylogenetic analysis based on combined ITS, LSU, SSU and datasets revealed that these taxa are related to the family Dictyosporiaceae. Morphological characteristics, along with multi-locus phylogenetic analysis, supported the establishment of sp. nov. and sp. nov., as well as the introduction of a novel genus , which accommodates comb. nov. (≡). In addition, four new host records are introduced for from , from , and , from , and from and . Detailed descriptions, micrographs of the new taxa and a phylogenetic tree are provided.
