  • A seed-borne fungus, Curvularia sp. EML-KWD01, was isolated from an indigenous wheat seed by standard blotter method. This fungus was characterized based on the morphological characteristics and molecular phylogenetic analysis. Phylogenetic status of the fungus was determined using sequences of three loci: rDNA internal transcribed spacer, large ribosomal subunit, and glyceraldehyde 3-phosphate dehydrogenase gene. Multi loci sequencing analysis revealed that this fungus was Curvularia spicifera within Curvularia group 2 of family Pleosporaceae.

  • The fungal strain KNU16-004 was isolated from a field soil sample collected in Seoul. The isolate was identified as Leptosphaerulina australis based on morphological characterization and phylogenetic analysis using the internal transcribed spacer (ITS), large subunit (LSU) rDNA regions, and ${\beta}-tubulin$ (Tub2). This is the first report of Leptosphaerulina australis in Korea.

  • New $\alpha$-pyrones (1 and 2) and cyclohexenones (13 and 14) were isolated along with known analogues (3, 5−12) from the ethyl acetate extract of the whole broth of the fungus Paecilomyces lilacinus, a strain derived from a marine sponge Petrosia sp. Their structures were established by interpretation of 1D and 2D NMR, and FABMS data. It is interesting to isolate cyclohexenone derivatives from the genus Paecilomyces (family Trichocomaceae, order Eurotiales), since these cyclohexenones were previously reported only from far distinct genera, Phoma and Alternaria (family Pleosporaceae, order Pleosporales). Compounds 6, 7, and 9 were evaluated for cytotoxicity against a small panel of human solid tumor cell lines. Their cytotoxicity was insignificant upto a concentration of 30 ${\mu}g/mL$.
