Characterization of Paecilomyces variotii and Talaromyces amestolkiae in Korea Based on the Morphological Characteristics and Multigene Phylogenetic Analyses.

During fungal diversity surveys of the order Eurotiales in Korea, two fungal strains, EML-DG33-1 and EML-NCP50, were isolated from samples of rat dung and fig tree leaf collected at a garden located in Gwangju in 2014. To complete the National Species List of Korea, it is a prerequisite to verify whether many questionable species, which were previously recorded but not confirmed, indeed present in Korea. Herein, the isolates were confirmed as undescribed species, Paecilomyces variotii and Talaromyces amestolkiae based on the combination of morphological and phylogenetic analyses of multigenes including the rDNA internal transcribed spacer, β-tubulin, and RNA polymerase II subunit 2.
