Freshwater is a diverse and complex environment for fungi and provides several types of habitat including plant
litter, sediment, and carcasses. We collected plant litter from the main stream and branch streams of Nakdong River, Sohancheon
in Samcheok, and Geumoreum in Jeju. From several samples of plant litter, we isolated 8 fungal strains belonging to 4
Montagnulaceae species unrecorded in Korea: , , Paraphaeosphaeria
, and Paraphaeosphaeria . These fungi were identified by phylogenetic analysis using the internal transcribed
spacer (ITS) region and examination of morphological characteristics. Montagnulaceae is known as one of the families in
Pleosporales and includes coniothyrium-like fungi. In this study, we described phylogenetic analysis and mycological characteristics
of these species, and this is the first report of these taxa in Korea.
