  • During a survey of fungal species in South Korea, a species of Volutella ciliata was isolated and described based on the analysis of the internal transcribed spacer region of its rDNA and its morphological characteristics. This is the first record of Volutella ciliata isolated from crop field soil in Korea.

  • Boxwood is a representative ornamental shrub that is widely used in landscaping horticulture. After pruning, damaged leaves or stems of boxwoods are unavoidably vulnerable to infection by various plant pathogens. Several boxwood diseases caused by fungi, such as Volutella blight and Macrophoma leaf spot, have been reported worldwide including Republic of Korea. In this study, we isolated and identified fungal pathogens of boxwood diseases that occurred in Korea and characterized their morphological and taxonomic characteristics. Boxwood samples showing blight symptoms were collected in Seoul, Republic of Korea, and the putative fungal pathogens Pseudonectria buxi, P. foliicola, and Neofusicoccum buxi were successfully identified. Investigation of the morphological features of the field isolates, including mycelial growth and conidial morphology, and phylogenetic analysis of multiple DNA barcode loci revealed that there were some morphological and genetic variations among isolates, but all of the analyzed isolates were closely related to the corresponding reference strains. We also found that P. foliicola strains were more virulent than P. buxi, and the N. buxi strains isolated in this study were weak pathogens or saprophytes. The results of our study will contribute to the development of control strategies for boxwood diseases caused by fungi and accelerate research on the complex ecology of boxwood diseases.

  • We isolated nine fungal strains from different environmental materials collected from different locations during a survey of fungal diversity in Korea. Using molecular phylogenetic analyses and morphological characteristics, nine previously undescribed strains were identified and assigned to the species Collariella robusta, Fusicolla acetilerea, Hongkongmyces pedis, Hongkongmyces snookiorum, Mariannaea fusiformis, Metarhizium pemphigi, Pallidocercospora crystallina, Scopulariopsis candida, and Volutella citrinella. Diverse environmental samples may thus be a promising source for isolating and investigating novel fungal species, thus sampling efforts should be increased in future studies. This study also reports identification of some rare fungal species belonging to the genera Hongkongmyces and Pallidocercospora from Korea.
