Genus Eurotium is a type of ascomycete fungus that is commonly found in soil, plants, and decaying organic matter. There are several synonyms for this genus, including Aspergillus, Emericella, and Neosartorya. These synonyms are used due to the morphological and genetic similarities shared by Eurotium with other genera in the Aspergillaceae family. Eurotium species are known for their ability to produce mycotoxins and their potential use in the fermentation industry. The taxonomy of Eurotium is constantly evolving as researchers strive to better understand the relationship between this genus and other fungi in its family.
