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.

Amanita subgenus Lepidella is a well-known group that includes lethal amanitas. However, the taxonomic investigation of Korean Amanita species is still in progress. In this study, we collected Amanita specimens in Korea from 2009 to 2015 and classified 22 of them as subgenus Lepidella based on the morphology. Phylogenetic analysis of the 22 Amanita specimens based on the internal transcribed spacers sequences identified 16 phylogenetic species which included three undescribed Amanita species (A. sepiacea, A. modesta and A. kotohiraensis). Microscopic features of newly recorded Amanita species were photographed and line drawings were made. All collections cited here are deposited in the Herbarium Conservation Center of the National Institute of Agricultural Sciences.

A molecular phylogenetic analysis of 40 fungal specimens that were collected from the Korean peninsula from 2000 to 2015 and recorded as Amanita virosa was performed using internal transcribed spacer sequence data. Results confirmed that Amanita oberwinklerana (14 specimens), Amanita rimosa (5), Amanita pallidorosea (20), and Amanita virosa (1) belong to section Phalloideae of subgenus Lepidella, and the morphological features of these specimens were re-examined. The former three species with deadly poisonous white mushrooms were not yet recorded in Korea. Because of their morphological similarities with A. virosa, they are frequently overlooked or misidentified in the field. All collections were deposited in the Herbarium Conservation Center of the National Institute of Agricultural Sciences.

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.

For the purpose of investigating the distribution and flora of wild mushrooms in Korea, this study was conducted primarily on the genus Amanita. Through survey of Suweon, Kwangneung, Mt. Chiri, Taegwanryung, Yeongdong district and Mt. Hanta, 25 species of Amanita including 3 unrecorded species were discovered and are described in this paper. The author proposes to group 25 Korean species of Amanita into 3 subgenera according to morphological characteristics by the modern taxonomic system, and also designated the 3 unrecorded species of Amanita including one variety in Korean common name.

In search for plant-derived cytotoxic compounds, it was found that the MeOH extracts obtained from Amanita pantherina(DC. ex Fr.) Krombh exhibited significant cytotoxic activity against human tumor cell line. The classical fractionation on the basis of the inhibitory activity upon the growth human tumor cell line. in vitro, and repeated column chromatography afforded several cytotoxic compounds from Amanita pantherina (DC, ex Fr.) Krombh. (omitted)

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.
