Isolation and Characterization of Four Unrecorded Mucor Species in Korea

During an investigation of fungi of the order Mucorales from freshwater and sediment samplesin Korea, we isolated six strains, NNIBRFG6649, NNIBRFG6255, NNIBRFG1498, CNUFCYJ13,CNUFC-YR7, and NNIBRFG2739. The morphology and phylogeny of these strains wereanalyzed. Based on the morphological characteristics and molecular data from internal transcribedspacer (ITS) region, the isolates NNIBRFG6649 and NNIBRFG6255 were identified asMucor abundans, and M. aligarensis, respectively. The isolates NNIBRFG1498 and CNUFC-YJ13were identified as M. moelleri, whereas the isolates CNUFC-YR7 and NNIBRFG2739 were identifiedas M. heterogamus. To the best of our knowledge, M. abundans, M. aligarensis, M. moelleri,and M. heterogamus have not yet been reported in Korea.

Characterization of Two New Records of Zygomycete Species Belonging to Undiscovered Taxa in Korea

During a biodiversity survey of undiscovered taxa in Korea, two zygomycetous fungal strains were isolated. The first strain, EML-FSDY6-1 was isolated from a soil sample collected at Dokdo Island in the East Sea of Korea in 2013, and the second strain, EML-DG-NH3-1 was isolated from a rat dung sample collected at Chonnam National University garden, Gwangju, Korea in 2014. Based on the morphological characteristics and phylogenetic analysis of the internal transcribed spacer, 18S and 28S rDNA, actin and translation elongation factor-1α genes. EML-FSDY6-1 and EML-DG-NH3-1 isolates were confirmed as zygomycete species, Absidia pseudocylindrospora and Absidia glauca, respectively. Neither species has previously been described in Korea.

Confirmation of Two Undescribed Fungal Species from Dokdo of Korea Based on Current Classification System Using Multi Loci

Using dilution plating method, 47 fungal isolates were obtained from a soil sample collected from Dokdo in the East Sea of Korea in 2013. In this study, two fungal isolates, EML-MFS30-1 and EML-DDSF4, were confirmed as undescribed species, Metarhizium guizhouense and Mortierella oligospora in Korea based on current classification system using multi loci including rDNA internal transcribed spacer, large subunit, small subunit, and beta-tubulin (BTUB) genes. Herein, detailed morphological descriptions on characters of the undescribed fungal species as well as their molecular phylogenetic status are provided with comparisons to related species.

A New Record of Penicillium raphiae Isolated from Agricultural Soil of Ulleung Island, Korea

A fungal isolate EML-NCP01 was recovered from agricultural soil in Ulleung Island, Korea. Phylogenetic analysis of internal transcribed spacer and beta-tubulin genes identified the isolate as the Penicillium species P. raphiae. Morphologically, the EML-NCP01 isolate was identical to the previous description of P. raphiae. The species presented here has not been reported in Korea.
