Ganoderma lucidum has a long history for traditional medicine in Asian countries. However, taxonomy of Ganoderma species remains controversial, since it was initially classified on the basis of morphological characteristics. Recently, Ganoderma sichuanense was proposed as a re-proposed name for Ganoderma lucidum in China. Likewise, all of the Korean G. lucidum were clustered into 1 group together with G. sichuanense from China, when a phylogenetic analysis was undertaken based on the ITS rDNA sequences of the Ganoderma species. Furthermore, G. lucidum from Europe and North America were clustered into different group. Based on these results, re-consideration of naming Korean cultivated G. lucidum is needed.

Korean freshwater turtles are divided into native turtles, Chinemys reevesii in Geoemydidae, Pelodiscus sinensis in Trionychidae, and imported turtles, Trachemys scripta elegans, T. s. scripta, Pseudemys rubriventris and Ocadia sinensis. In this study, we determined the distribution of Korean freshwater turtles based on a field study and literature study, and considered the taxonomic position of unidentified native turtles. The study was carried out between May 2010 and November 2011 during the day time, and the capturing tool used to collect turtles consisted of net and metal frame. C. reevesii and P. sinensis were found in 16 and 11 places, respectively. C. reevesii, which inhabits the Korean peninsula, is a taxonomically controversial species, but it is presumed that the turtle belongs to Mauremys. Moreover recent taxonomic studies of the soft-shell turtle have shown that the Korean native species is P. maackii, and P. sinensis was imported from abroad and has been in the natural habitats of Korea since 1970s. The exterior shape and skeletal form of P. maackii and P. sinensis are nearly similar. However, the skin color and yellow spots on the shell could be used to distinguish the two species.

국내에 분포하는 대사초절에 속하는 3분류군의 외부형태형질을 분석하고 분자계통학적 연구를 수행하여 이들 간의 유연관계를 밝혔다. 대사초절 내의 기본종인 대사초의 외부형태학 특징을 재검토하여 기존 문헌과의 차이를 파악하였으며, 식물상 문헌 및 표본을 통해 국내 분포도를 작성하였다. 문헌에 언급된 형질들 중에서 잎의 형태는 생육지 조건에 따라 변이가 심하였지만, 지하경 생장 양상, 잎과 과낭의 털의 존재 등은 종수준에서 구분하는데 좋은 형질이었다. 분자계통학적 연구에서 털대사초는 독립된 종으로 처리되는 것을 지지하였다.
