Staphylotrichum sinense, a new hyphomycete classified in the Chaetomiaceae (Ascomycota), was isolated from soil in Jianshui county, Yunnan Province. It is characterized by globose and ochreous conidia born laterally on aerial hyphae, and micronematous, unbranched and 0–1-septate conidiophores, sometimes reduced to conidiogenous cells. Morphologically, Staphylotrichum sinense is similar to Staphylotrichum boninense, but it can be distinguished by lacking of macronematous conidiophores and having larger conidia. Phylogenetically Staphylotrichum sinense formed a single clade within Staphylotrichum species, and is closely related to Staphylotrichum boninense and Staphylotrichum brevistipitatum.

Exophiala is an important genus, with several species associated with infections in humans and animals. In a survey of soil fungal diversity in Yunnan province, PR China, a novel taxon, Exophiala pseudooligosperma sp. nov., was identified based on combined morphological and molecular phylogenetic features. Morphologically, this species is characterized by having torulose, septate hyphae and swollen, terminal or intercalary conidiogenous cells arising at acute angles from aerial hyphae. Phylogenetic analysis of the combined sequences of the internal transcribed spacer, the small and large nuclear subunit of the rRNA gene and part of the β-tubulin gene confirmed the phylogenetic position of the new species within the genus Exophiala.
