  • 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: Paraconiothyrium archidendri, Paraphaeosphaeria sporulosa, Paraphaeosphaeria michotii, and Paraphaeosphaeria viridescens. 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.

  • The present study reports 16 species of Ascomycota that were previously unknown in Korea, namely Acremonium cellulolyticus (KNU14-25), Acremonium zonatum (KNU14-15), Chaetomium madrasense (KNU14-9), Cladosporium silenes (KNU 14-18-1), Humicolopsis cephalosporioides (KNU15-3), Leptosphaerulina chartarum (KNU14-16), Paecilomyces marquandii (KNU14-8), Paecilomyces tenuis (KNU14-18-2), Paraphaeosphaeria sporulosa (KNU15-2), Penicillium rubidurum (KNU14-12), Pochonia suchlasporia (KNU15-6), Sporothrix inflata (KNU15-8), Thielavia hyrcaniae (KNU15-1), Thielavia terricola (KNU14-23-1), Xylogone sphaerospora (KNU15-7), and Zopfiella longicaudata (KNU15-5). These fungal species were isolated from soil samples collected from various regions of Korea and identified based on their morphological characteristics and rDNA internal transcribed spacer sequence data. Full descriptions and illustrations for each species are provided.

  • In this study, we analyzed the changes in fungal populations of red-pepper fields employing eco-friendly farming methods, such as microbial agents and crop rotation, by using polymerase chain reactions coupled with denaturing gradient gel electrophoresis (PCR-DGGE). Primer specific for fungi were used to determine the contribution of domains to the microbial community. Analysis of planted and non-planted soil samples applying PCR-DGGE technology offered evaluation of long-term patterns in fungal species richness. To evaluate the stability of DGGE patterns from different soils, comparison of planted and non-planted soil samples were compared using PCR-DGGE. The number of DNA fragments obtained from all planted soil samples by DGGE separation was far greater (14 to 15 bands) than that of the non-planted soil samples (3 to 4 bands). In addition, 14 bands were observed from crop continuation soil treated with agrochemicals and 18 bands from crop rotation soil treated with microbial agents. The PCR-DGGE analysis suggests that the use of crop rotation and microbial agents benefits the fungal community more than crop continuation using agrochemicals. These results indicate that crop rotation with microbial agents was better able to support beneficial organisms, enable more effective biological control and maintain a healthier balance of nutrients, organic matter and microorganisms.
