Abstract
Two strains of Stachybotrys, identified based on morphology and phylogenetic analysis, were isolated from rocky desertification soils in Yunnan province. Phylogenetic analyses inferred from three loci (the internal transcribed spacer of the nuclear ribosomal RNA gene, β-tubulin and RNA polymerase II second-largest subunit) showed that the two strains formed a single clade and were introduced as a new species of Stachybotrys, S. qujingensis. S. qujingensis is characterized by having ampulliform or broadly fusiform conidiogenous cells and dark olivaceous-green, oblong-ellipsoidal conidia. Phylogenetically, S. qujingensis is most closely related to S. musae, but it distinguishes the latter by longer and narrower conidia. Descriptions, illustrations and phylogenetic placement of S. qujingensis were provided.
期刊介绍：
Published by the Microbiology Society and owned by the International Committee on Systematics of Prokaryotes (ICSP), a committee of the Bacteriology and Applied Microbiology Division of the International Union of Microbiological Societies, International Journal of Systematic and Evolutionary Microbiology is the leading forum for the publication of novel microbial taxa and the ICSP’s official journal of record for prokaryotic names.
The journal welcomes high-quality research on all aspects of microbial evolution, phylogenetics and systematics, encouraging submissions on all prokaryotes, yeasts, microfungi, protozoa and microalgae across the full breadth of systematics including:
Identification, characterisation and culture preservation
Microbial evolution and biodiversity
Molecular environmental work with strong taxonomic or evolutionary content
Nomenclature
Taxonomy and phylogenetics.
