In Seoul, a majority of plant communities have undergone significant changes over the last few decades; however, how wood decay fungi have responded and adapted to the changes in vegetation remains unknown. Through an ongoing investigation of Korean indigenous fungi, ca. 300 specimens with poroid basidiocarp were collected in Seoul during 2008~2012. Morphological examination and molecular analysis using the internal transcribed spacer and nuclear large subunit ribosomal DNA region sequences helped identify 38 species belonging to 28 genera, 10 families, and 5 orders in this area. Among them, three polypores, Abundisporus pubertatis, Coriolopsis strumosa, and Perenniporia maackiae were found to be new to South Korea.

문제 정의
In Seoul, many plant communities have undergone changes over the last few decades [13]; however, the ecological impact on wood decay fungi due to the changes in vegetation remains unknown. In this study, we focused on the polypore diversity among the wood decay fungi. Previously, 28 species of polypores were reported to exist in Seoul [14-20].

Morphological examination.Basidiocarps collected from Seoul between 2008 and 2012 were used in this study. The collected areas are represented in Fig.

Around 300 polypore specimens were sorted from the materials collected in Seoul between 2008 and 2012. Specimens that were immature, too small, or in poor condition were excluded from the analysis, which left approximately 240 specimens for the examination. Our analysis helped identify 38 species of polypores belonging to 28 genera, 10 families, and 5 orders.
DNA sequencing was performed through the Macrogen sequencing service (Seoul, Korea). The sequences obtained in this study were deposited in NCBI GenBank (accession Nos. KF356153~ KF356162). Each sequence was compared to the reference sequences in GenBank, using a BLAST search (http://blast.
The following abbreviations are used: L = mean spore length, W = mean spore width, and n = the number of spores measured/the number of examined specimens. The study materials were deposited at the National Institute of Biological Resources, Incheon, South Korea (KB) and/or the Korea University Culture Collection, Korea University, Seoul, South Korea (KUC).
pubertatis (KUC20080726-14), while the ITS sequence was not successfully amplified, the identity of the polypore could be confirmed using the nLSU sequence. Three specimens of C. strumosa (KUC20091016-32, KUC20110916-07, and KUC20111027-09) clustered with C. strumosa from China, with high support (0.96 posterior probability value [p.p.]) (Fig. 5B), and two specimens of P.maackiae (KUC20080801-33 and KUC20080801-45) grouped with P. maackiae from China, with high support (0.93 p.p) (Fig. 5C). The detailed descriptions of these three species are presented below.
성능/효과
Among the identified species, three polypores were confirmed to be new to South Korea, namely, Abundisporus pubertatis, Coriolopsis strumosa, and Perenniporia maackiae (Figs. 2~4). They were found in Mt.
Since the field surveys were performed irregularly during a 5-year period and we may not have captured every single species, our survey suggests that Trametes versicolor, Perenniporia fraxinea, and Hyphodontia tropica are widespread in this region. In addition, 20 species were newly reported in Seoul: Abundisporus pubertatis, Antrodia heteromorpha, A. malicola, Antrodiella semisupina, Ceriporia lacerata, Coltricia cinnamomea, Coriolopsis strumosa, Daedaleopsis confragosa, D. styracina, Heterobasidion ecrustosum, Hyphodontia tropica, Junghuhnia nitida, Microporus vernicipes, Perenniporia maackiae, P. ochroleuca, Porodisculus orientalis, Postia stiptica, Pycnoporus coccineus, Skeletocutis nivea, and Trametes orientalis.
