  • Through a survey of symbiotic endophytic fungi, we isolated an endophyte fungal strain from the roots of Glycyrrhiza uralensis in Korea. The isolated fungal strain was identified using its morphological characteristics and through phylogenetic analysis of the internal transcribed spacer, the large subunit rDNA region, and the translation elongation factor region. The strain was identified as Neocosmospora rubicola. This species has not been previously reported in Korea. In this study, we report its isolation from the roots of Glycyrrhiza uralensis in Korea, followed by the characterization and identification of the strain.

  • Endophytic fungi were isolated from needle leaves of two conifer species in Korea. The fungal isolates were identified based on their morphological characteristics and phylogenetic analyses of their internal transcribed spacer and large-subunit rDNA regions. Three species of endophytic fungi, namely Celosporium laricicola, Neocatenulostroma germanicum, and Phaeophleospora eucalypticola were the first records in Korea. In this study, we reported the morphological and phylogenetic characteristics of these fungi.

  • Some fine specimens of Annulariopsis bunkeiensis were collected from two fossil sites of the Amisan Formation of Nampo Group distributed in the Jogaegol, Boryeng City, Chungnam Province. According to our detailed study from our new material, the leaves of A. bunkeiensis are not mucronate, but emarginate at their apices. Accordingly, we revised the diagnostic characters given by Kimura and Kim (1988) mainly in regard to the leaf apex.

  • In this study, endophytic fungi were isolated from the leaves of evergreen woody plants in Hansando Island in South Korea. The fungal isolates were identified based on morphological characteristics and phylogenetic analysis of the DNA sequences of the internal transcribed spacer and the large subunit regions of rDNA. It was confirmed that two endophytic fungal species, Muyocopron lithocarpi and Didymocyrtis cladoniicola, isolated in this study have not previously been reported in South Korea.

  • We isolated endophytic fungi from the roots of Quercus spp. in Korea. The isolates were identified based on morphological and molecular characteristics from the nucleotide sequences of the internal transcribed spacer and large subunit of rDNA regions. We confirmed that the four species we isolated - Oidiodendron citrinum, Acremonium crotocinigenum, Mammaria echinobotryoides, and Pleotrichocladium opacum - have not been recorded previously in Korea. Herein, we present their morphological characteristics and the result of phylogenetic analysis.
