Forty-two endophytic fungi were isolated from the roots of coastal plants, such as Maxim., L., , and Ohwi, naturally growing in Taean peninsula. The identity of the
endophytic fungal strains was analyzed using the sequence of internal transcribed spacer regions. All fungi belonged to the
phylum Ascomycota, and they were classified into eight orders (Botryosphaeriales, Capnodiales, Diaporthales, Dothideales,
Eurotiales, Helotiales, Hypocreales, and Pleosporales) and thirteen genera (). Among the
analyzed fungi, the fungi belonging to the genus in Eurotiales were the most widely distributed. The host plant L. was found to contain the most diverse endophytic fungal species among the coastal plants.
