  • We collected nearly 70 specimens of Amanita species during a diversity study of Korean mushrooms conducted in 2012. In this study, we primarily investigated 23 Amanita specimens belonging to sections Amanita and Vaginatae. Based on sequence data of the internal transcribed spacers and partial large subunit of ribosomal RNA and morphological characteristics, we identified the following 15 phylogenetic species: A. alboflavescens, A. ceciliae, A. farinosa, A. fulva, A. griseofolia, A. ibotengutake, A. melleiceps, A. orientifulva, A. pantherina, A. rubrovolvata, A. sinensis, A. subglobosa, A. vaginata, A. cf. vaginata f. alba, and an undescribed Amanita species. In this study, four of the identified Amanita species (A. griseofolia, A. ibotengutake, A. orientifulva, and A. sinensis) were reported for the first time in Korea.

  • 광대버섯 Lepidella 아속은 독광대버섯군 (Sect. Phalloideae)가 속해있는 것으로 잘 알려진 그룹이다. 그렇지만, 국내 광대버섯 종의 분류학적 연구는 여전히 진행 중이다. 이번 연구에서, 우리는 국내에서 2009년부터 2015년까지 수집된 광대버섯 표본 중 형태학적 기반으로 Lepidella 아속에 속하는 22 표본을 분석하였다. Internal transcribed spacer (ITS) 영역의 염기서열을 기반으로 분자유전학적계통분석을 진행한 결과, 16종의 분류군이 동정되었으며 이 중 국내 미기록인 Amanita sepiacea, Amanita modesta와 Amanita kotohiraensis가 포함되어있었다. 처음 보고되는 3종의 현미경적 특징은 기록과 함께 이미지를 저장하고 삽화를 그렸다. 본 연구에 사용된 모든 표본은 국립농업과학원 표본실에 보관되어 있다.

  • 본 연구는 2000년부터 2015년까지 한국에서 수집되어 Amanita virosa로 동정된 40개 표본의 분자계통학적 종동정을 위해 internal transcribed spacer rDNA 영역의 염기서열을 사용하여 수행하였다. 이번 연구에서 Lepidella 아속의 Phalloideae절에 속하는 Amanita oberwinklerana의 14개 표본, A.cf. rimosa 5개 표본, A. pallidorosea 20개 표본 및 A. virosa 1개 표본을 확인하였고, 그들의 형태학적 특성을 재조사하였다. 백색 계열의 맹독성 버섯에 속하는 위 3종(A. oberwinklerana, A.cf. rimosa, A. pallidorosea)은 아직 국내에는 잘 알려지지 않았지만, 형태학적 특징들이 A. virosa와 매우 유사하여 존재하더라도 오동정되었을 가능성이 높다. 본 연구에 사용된 모든 표본은 국립농업과학원 표본실에 보관되어 있다.

  • Amanita Pers. is a well-known monophyletic mushroom genus with a broad distribution. However, the diversity of Korean Amanita species has been underestimated, and most taxonomic studies conducted in Korea have only investigated their morphological characteristics. This approach is frequently insufficient for correct identification in fungal classification; therefore, we constructed a phylogeny of Amanita subgen. Lepidella in order to understand the phylogenetic placements of 16 Amanita specimens collected in Korea in 2012. The phylogeny constructed using the sequence data of the internal transcribed spacers and the partial large subunit of ribosomal RNA identified nine Amanita species (A. citrina, A. excelsa var. spissa, A. flavipes, A. fritillaria, A. oberwinklerana, A. pallidorosea, A. rubescens, A. subjunquillea, and A. volvata); of these, A. fritillaria, A. oberwinklerana, and A. pallidorosea are new to Korea.

  • Two new species of Amanita were collected in central areas of Korea from 1997 to 2000. They were identified, described and illustrated. One of them, Amanita longstipeta has turtle-shaped warts of crust and its base is longer under the soil than is above the soil. The other A. aureofarinosa is covered with golden yellow farina and annulus is absent. Both are solitary in soil with sand.

  • Amanita (Agaricales, Basidiomycota) is one of the most well-known genera composed of poisonous mushrooms. This genus of almost 500 species is distributed worldwide. Approximately 240 macrofungi were collected through an ongoing survey of indigenous fungi of Mt. Jeombong in Inje County, Korea in 2014. Among these specimens, 25 were identified as members of Amanita using macroscopic features. Specimens were identified to the species level by microscopic features and molecular sequence analyses of the internal transcribed spacer and large subunit of nuclear ribosomal RNA. We molecularly identified 13 Amanita species, with seven species matching previously recorded species, four species (A. caesareoides, A. griseoturcosa, A. imazekii, and A. sepiacea) new to Korea, and two unknown species.

  • Molecular events that cause tumor formation enhance a number of HOX genes, called switch genes, coding for RNApolymeraseII transcription factors. Thus, in tumor cells, RNApolymeraseII is more active than in other somatic cells. Amanita phalloides contains amanitin which inhibits RNApolymeraseII. Partial inhibition with amanitin influences tumor cell - but not normal cell - activity. To widen the treatment spectrum, dilutions of Amanita phalloides, containing amanitin, are applied to a patient with mammary duct cancer. For monitoring tumormarkers, different doses of amanitin are applied. The former duplication time of tumor growth represented three months; however within a period of 18 months the patient can be stabilized without further growth of the tumor. There are also no severe symptoms, no liver damage and no continuous erythrocyte deprivation. This new principle of tumor therapy shows high potential to provide a medical treatment.

  • In order to elucidate the mechanism of toxic action of a pisonous mushroom, Amanita pantherina, biochemical effects of the mushroom extracts on mice were studied. A hotwater extract of Amanita pantherina injected intraperitoneally into male ICR mice evoked signs similar to those observed clinically upon acute poisoning by the mushroom and also changed the levels of component enzyme activities in blood, liver and urine. The serum cholinesterase activity was decreased significantly during 1-3 h after injection.
