Abstract
Research on fungi isolated from freshwater environments contribute to expanding the fungal diversity and species inventory of freshwater ecosystems, as well as aiding in understanding the roles they play within these ecosystems. This study presents detailed descriptions and phylogenetic tree of 10 fungal species isolated from various freshwater environments in South Korea. These species were isolated from freshwater environments, such as plantlitter, sediment, and filtered freshwater. Identification of based on morphological characteristics and phylogenetic analysis using the DNA sequences from the internal transcribed spacer (ITS), elongation factor (EF1), calmodulin (cmd), β-tubulin (btub), and RNA polymerase II (rpb2) coding genes, depending on the species. The following species were recorded for the first time in Korea: Plectosphaerella pauciseptata NNIBRFG186, Striatibotrys rhabdosporus NNIBRFG2094, Gibellulopsis serrae NNIBRFG1912, Trichoderma hunanense NNIBRFG33378, T. Albofulvopsis NNIBRFG34098, Curvularia americana NNIBRFG34293, Phacidium mollerianum NNIBRFG28409, Mucor brunneogriseus NNIBRFG50199, M. laxorrhizus NNIBRFG37671, and M. pseudolusitanicus NNIBRFG39976.
