Aspergillus is a monophyletic genus comprising the subgenera Aspergillus, Circumdati, Cremei, Fumigati, Nidulantes and Polypaecilum. The subgenus Circumdati contains many economically important species and mycotoxin producers. Section Jani was recently introduced with morphological and molecular support. In the present study, two strains isolated from farmland soil were assigned in section Jani based on multi-locus phylogenetic analyses but showed low similarity with existing species. Further morphological observation found they had wider vesicles and conidia connections which were different from the known species. Based on phylogenetic and morphological data, Aspergillus yunnanensis was introduced as the third species in section Jani. Members in section Jani are rarely distributed, this is the first report of this section in China.
