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.

Poisoning with mushroom containing amatoxin may be a real medical emergency and is characterized by long incubation time lag, gastrointestinal symptoms, hepatotoxic phase and sometimes death. We report a family of parents and two children who ingested wild mushroom and recovered from varying degrees of hepatotoxicity. After eating cooked wild mushroom and its soup, they all developed abdominal pain, vomiting and diarrhea 11 hours later, Their liver enzymes reached peak level between 48 and 72 hours after the ingestion. Among the family members, 5-year-old girl showed the most severe hepatic toxicity of AST/ALT 14,099/13,176 IU/L. They were all treated with supportive measures including repeated activated charcoal and penicillin G and recovered from the hepatotoxicity between 7 and 28 days after the ingestion. Being based on the shape and a typical course of the amatoxin poisoning, we presume that this wild mushroom belongs to Amanita virosa.

Phalloides syndrome has usually occurred after incidental mushroom ingestion. It is sometimes difficult to differentiate toxic mushrooms from edible ones, especially in lay person because of their morphological similarities. In Korea, Amanita virosa and Amanita subjunquillea have been reported as a cause of fulminant hepatic failure in mushroom poisoning (phalloides syndrome). We report a case of phalloides syndrome who came to death with fulminant hepatic failure even though we planned liver transplantation and used T-PLS(R) (Twin Pulse Life Support) for hemodynamic support while waiting for the donor.

Antifungal and antibacterial activities of 108 extracts from 36 species of mushrooms in Korea were screened. The powder of fruiting body of each mushroom was extracted with petroleum ether, 80% ethanol and distilled water subsequently. Among these, five extracts including the ethanol extract of Agaricus subrutilescens, seven extracts including the water extract of Amanita virosa, nine extracts including the water extract of Amanita pantherina and twenty five extracts including the water extract of Lycoperdon perlatum showed antibiotic activities against yeasts, fungi, Gram-negative bacteria and Gram-positive bacteria, respectively.

The antifungal activities of 153 extracts from 51 species of Korean mushroom on six phytopathogenic fungi were investigated. The powder of fruit-body of each mushroom was extracted with petroleum ether, 80% ethanol and distilled water. The water extracts of four mushrooms including Amanita virosa showed antifungal activities on Alternaria alternata, Colletotrichum graminicola, Fusarium solani, Idriella bolleyie. The 80% ethanol extracts of seven mushrooms including Boletus auripes showed antibiotic activities against A. alternata, C. gramincola, Cylindrocarpon destructans, F. solani, F. oxysporum cucumerinum, and I. bolleyie. The petroleum ether extracts of six mushrooms including Amanita citrina showed antibiotic activities against A. alternata, C. destructans, and C. graminicola. The 102 extracts of 34 mushrooms including Agaricus arvensis didn't show antibiotic activities.

The aim of this study was to investigate the physiological functionalities of 60 wild mushroom methanol extracts. We determined their fibrinolytic and ${\alpha}-glucosidase$ inhibitory activities. Among them, 11 mushrooms showed fibrinolytic activity. In particular, Armillaria sp. showed the greatest enzyme activity (4.2 plasmin units/ml) in a fibrin plate assay. The fibrinolytic activities of Amanita virosa. Gymnophilus sp. and Lepista nuda were 2.3, and the activities of Amanita citrina and Cortinarius alboviolaceus were 2.1 and 2.0 plasmin units, respectively. In a ${\alpha}-glucosidase$ inhibitory activity test, Naematoloma fasciculare showed the greatest inhibitory activity at 98.5%. The ${\alpha}-glucosidase$ inhibitory activities of Suillus luteus and Gomphidius maculatus were 66.6% and 61.5%, respectively. This study suggests that both Armillaria sp. and N. fasciculare can be used as candidates for the development of new medicine effective to cardiovascular diseases and biofunctional food.

Mushroom fruiting was investigated in pine and oak dominated forest stands in Songni National Park located in central Korea for six years from 2003 to 2008, in order to understand the relationship between mushroom diversity and the environmental factors, precipitation, temperature, soil moisture and vegetation. The most frequent fruiting families were those of ectomycorrhizal mushrooms, Tricholomataceae, Amanitaceae, Russulaceae, Cortinariaceae, and Boletaceae. The frequency of mushroom fruiting varied from 94 to 167 species per year, with July and August having the highest(13~90 species). Mushroom fruiting was positively correlated to precipitation(r=0.897), using Palmer Drought Severity Index for the long term period and Standard Precipitation Index for short term period. Soil moisture content also affected mushroom fruiting, with Lactarius chrysorrheus and Russula virescens fruiting only at soil moisture content higher than 20%. Positive correlation between mushroom fruiting and temperature was also noted(r=0.77), with optimum rates at $21{\sim}25^{\circ}C$. Tricholoma flayayirens, Amanita gymnopus, Lactarius piperatus, Inocybe asteropora and Xerocomus chrysenteron were able to fruit at temperatures higher than $25^{\circ}C$. However, Laccaria amethystea, Amanita virosa and Russula mariae fruited at relatively wide temperature range. The influence of vegetation on mushroom fruiting was likewise noted, with 38 species, including Suillus bovinus and Boletopsis leucomelas being specific to pine dominated stands, while 42 species, including Polyporus arcularius and Hericium erinaceum were specific to oak dominated stands. On the other hand, around 50 species, including Laccaria laccata and Lycoperdon parlatum, were able to fruit in both types of vegetation. In conclusion, mushroom fruiting greatly varies with changes in precipitation, soil moisture, temperature and vegetation.
