In 2017, Talaromyces variabilis was isolated during a survey of fungal diversity in field soils in Korea. This isolate was described based on its morphological and molecular characteristics and it was identified molecularly using the partial 18S-ITS1-5.8S-ITS2-28S rDNA region and calmodulin (CaM)-encoding gene sequence data. Thus, this study reported morphological and multigene sequence characterization of T. variabilis.
