Memnoniella sinensis sp. nov., a new species from China and a key to species of the genus.

During a survey of fungal diversity in a deserted rocky area in Yunnan, PR China, a new species, Memnoniella sinensis, was identified. This new species is characterized by having phialidic conidiogenous cells with conspicuous collarettes, and aseptate, verrucose, ellipsoidal to sometimes ovoid, olivaceous brown to dark brown conidia. Morphologically, M. sinensis is similar to M. dichroa, but can be easily distinguished due to its hyaline conidiophores and smaller conidia. Phylogenetic analysis based on DNA sequences at five loci showed that our strain grouped together with M. dichroa and M. oenanthes. Here, the new species is described and illustrated, and a key to the species of the genus Memnoniella is provided.
