  • A fungal isolate, designated KNU-JJ-1824, was isolated from a soil sample collected from a field on Jeju, Korea. Colonies of the isolates cultured on PDA, MEA and CMAD for 14 days grew to diameters of 49~51 mm, 60~63 mm, and 47~50 mm, respectively. The colonies of this fungal isolate were dark green in color on both sides, and had irregular margins on the PDA media. Mycelia submerged and exhibited clear lines from the center to the edge on MEA media. On CMAD media, they were dark brown to greenish-brown, with narrow white margins. The shape of the conidia was guttulate, fusiform or clavate, and $1.9{\sim}3.4{\times}6.5{\sim}10.2{\mu}m$ in size. A molecular phylogenetic tree was constructed using dataset from small subunit (SSU) rDNA and the internal transcribed spacer (ITS) regions, and the isolate was found to cluster with Scleroconidioma sphagnicola UAMH 9731. Based on the results of the phylogenetic tree analysis and the cultural and morphological characteristics, the isolate was identified as Scleroconidioma sphagnicola. We report S. sphagnicola for the first time in Korea.
