Abstract

During a survey of fungal diversity in different provinces of South Korea in 2017, a new fungal isolate was discovered. This fungal isolate was identified as Westerdykella reniformis, based on its morphological characteristics and phylogenetic analysis, using internal transcribed spacer (ITS) and 28S ribosomal DNA (28S rDNA) sequence data. To our knowledge, W. reniformis has not previously been reported in South Korea. Thus, in this study, we report a new record of a species from the Dothideomycetes class in Korea, and provide a detailed description with morphological illustrations.
