***Backusella*** is the sole [genus](/source/Genus) of [zygote fungi](/source/Zygomycota) in the family **Backusellaceae**, which is classified in the order [Mucorales](/source/Mucorales).[1] Members of this genus have been often isolated from [plant litter](/source/Plant_litter), from locations around the world.[2]

## Taxonomy

C. W. Hesseltine and J. J. Ellis recognised the uniqueness of a new species, *B. circina*, warranted its classification in a new genus; in 1969 they established *Backusella*, named in honour of Professor M. P. Backus. Since then, several species previously placed in the archetypal [mucoralean](/source/Mucorales) genus *[Mucor](/source/Mucor)* were reassessed, found to be close relatives of *B. circina*, and combined into *Backusella* as additional *Backusella* species, while other species were discovered and classified outright as *Backusella*.[1] K. Voigt & P.M. Kirk established the family Backusellaceae to include *Backusella* in 2012, as they likewise recognised the uniqueness of the genus and the need to classify it within a distinct family.
