  • Four strains of Phellinus spp. was identified based on internal transcribed spacer(ITS) region of rDNA sequence analysis and morphological characteristics. Basidiocarps of all strains were effused-reflexed and hymenial surface was poroid. Hyphal system was dimitic and basidiospore was globose to ellipsoid. The amplification of ITS regions produced a DNA fragment of 500 to 780 by in all strains examined. The determined sequences were analyzed for the reconstruction of phylogenetic tree. From these results, Phellinus sp. KM-1, KM-2, and KM-4 was identified as P. hartigii, P. baumii, and P. linteus, respectively.

  • During our studies on the diverse endophytic fungi resident on conifer needles, many species of Cladosporium previously unreported in Korea were encountered. In this paper, we report on two species of Cladosporium from the needles of pine trees (Pinus spp.). Based on analyses of internal transcribed spacer gene sequence, and cultural and micromorphological characteristics, they were identified as C. oxysporum and C. sphaerospermum. Both species have not been hitherto reported in Korea.

  • The family Ulvaceae species are difficult to distinguish from one another on the basis of morphological and cytological criteria alone. ITS2 sequences are hewn to evolve quickly and have been reported to be useful for the study of intraspecific and interspecific variation and biogeography in algae (Bakker et al., 1992). We will here describe the basic characteristics of the ITS2 sequences in Ulva and Effteromorpha to compare our result with the above previous studies. (omitted)

  • The genus Hypomyces contains fungi that grow on mushrooms, including agarics, boletes, and Aphyllophorales. While 53 Hypomyces species have been reported worldwide, only one was in Korea. In this study, two new Korean species were identified as H. luteovirens and H. tubariicola based on morphology and internal transcribed spacer sequencing.

  • Soft rot in apple caused by Rhizopus oryzae was found for the first time in Korea. A detailed description of the specimen is given along with its internal transcribed spacer rDNA sequence. The fungus was identified as Rhizopus oryzae based on the mycological characteristics, molecular data, and pathogenicity testing.

  • Three isolates of Penicillium pimiteouiense were recovered from sandy beach soil samples in Penang Island, Peninsular Malaysia. All the isolates were identified based on morphological characteristics and phylogenetic analysis of internal transcribed spacer regions and ${\beta}$-tubulin gene. This is a first record of P. pimiteouiense in Malaysia.

  • A fungal strain was isolated from surface-sterilized roots of Rhododendron mucronulatum, a plant species belonging to the Ericaceae family, collected from Mt. Minjujisan, Korea. This fungal strain was identified as Rhizodermea veluwensis based on its morphological characteristics and based on phylogenetic analysis of its internal transcribed spacer regions and large-subunit rDNA. R. veluwensis has not been previously reported in Korea, and for the first time, we report and describe it herein.
