This study provides a comprehensive update on Bisifusarium fungi, a group that includes species used in cheese production and some that can cause human infections. Researchers examined 116 fungal isolates from around the world and identified 25 distinct lineages using DNA analysis. They formally described 8 new species and provided detailed descriptions and photos of previously poorly documented species. This work doubles the known diversity of this fungal genus and will help scientists and medical professionals better identify and understand these fungi.
