Aspergillus ustus is a very common species in foods, soil and indoor environments. Based on chemical, molecular and morphological data, A. insuetus is separated from A. ustus and revived. A. insuetus differs from A. ustus in producing drimans and ophiobolin G and H and not producing ustic acid and austocystins. The molecular, physiological and morphological data also indicated that another species, A. keveiisp. nov. is closely related but distinct from A. insuetus. Aspergillus section Usti sensu stricto includes 8 species: A. ustus, A. puniceus, A. granulosus, A. pseudodeflectus, A. calidoustus, A. insuetus and A. keveii together with Emericella heterothallica.
乌斯图曲霉是一种在食物、土壤和室内环境中非常常见的物种。根据化学、分子和形态学数据，将 insuetus 从 ustus 中分离出来并重新命名。insuetus 与 ustus 的不同之处在于产生 drimans 和 ophiobolin G 和 H，而不产生 ustic acid 和 austocystins。分子、生理和形态学数据还表明，另一个物种，A. keveiisp. nov. 与 insuetus 密切相关但不同。狭义的 Usti 节包括 8 个种：ustus、puniceus、granulosus、pseudodeflectus、calidoustus、insuetus 和 keveii 以及异宗配合的 heterothallica。
