Mushroom surveys and collections were conducted in the western and eastern forest areas in Cambodia, and then fungal biodiversity was analyzed by identifying mushrooms. One thousand and three hundreds eighty three specimens were identified by morphological and genetical characteristics, and were classified into 238 species, 160 genera, 52 families, 15 orders, and 3 phylums. The collected mushrooms were immersed in 70% ethyl alcohol for DNA extraction, and the rest of them were dried in the portable mushroom dryer for 12 hrs. Among these mushrooms, the genera Mycena (8.7%), Ganoderma (5.6%), Microporus (5.3%), Marasmius (4.2%), Marasmiellus (3.0%), Phellinus (2.5%), Trametes (2.5%), Hygrocybe (1.9%) and Pycnoporus (1.5%) were dominant. In the western Cambodia, 1,061 specimens were collected from Koh Kong forests, while 263 specimens were collected from the eastern Cambodia, Seima and Mondulkiri forests. Elevations of surveyed sites were ranged from 0 to 750 m above sea level. The number of species observed in the elevation of 251-500 m was the highest as compared to the other ranges of elevation. Daldinia concentrica, Microporus vernicipes, Microporus xanthopus, Pycnoporus coccineus, Stereum hirsutum, and Stereum ostrea were commonly distributed in all ranges of elevation, while the distribution of Ceratomyxa fruticulosa, Panus fulvus, Schizophyllum, Trametes versicolor, and Tyromyces chioneus were limited under 500 m. One hundred and forty one species including Amauroderma sp., Bjerkandera adusta, Trichaptum abietinum, and Tyromyces chioneus were collected only in Cardamom, while 20 species including Auricularia auricula-judae, Coriolopsis sanguinaria, Rigidoporus microporus, and Xylaria polymorpha were collected only in Seima. Ganoderma sp., Mycena sp., Marasmius sp., Microporus xanthopus, Phellinus sp., and Russula sp. were dominant species in both the western and eastern Cambodia. Species diversity indices in the eastern and western survey sites were 1.83 and 1.77, respectively, while evenness indices were 0.92 and 0.90. The species similarity index between two survey sites was 0.42.

Two hundred seventy-four microorganisms were isolated from the soil of abandoned mines around for selecting the heavy metal-degrading strains and their microbial diversity was analyzed. The specimens of macrofungi were isolated from the soil of abandoned mines around for selecting the heavy metal-degrading strains. Eunseong and Dogok in Gyeongsangbuk-do, for selecting the heavy metal-degrading strains. Soil was also collected from same location. Contents of heavy metals (Cd, Cu, Pb, Zn, Ni, Cr, and As) were determined spectrometically in fruiting bodies of forty eight wild macrofungi specimens with soils. When the analysed their transfer factor from soil to fruiting body, Amanita volvata have the highest transfer factor of cadmium and arsenic. And Mycena pura showed the highest in mercury, Marasmius pulcherripes in zinc, Laccaria laccata in nickel, and Collybia confluens in chrome. When compare the population of mushrooms between the contaminated mines and Mt. Chiak as the healthy area, Genus Russula and Collybia were collected both area, but Leucocoprinus, Coprinus, Suillus, Lepiost, Gyroporus, Lepista, Microstoma, Stropharia, and Agrocybe were only in the contaminated mine area.

For the searching of antibiotics in the mushroom, we studied on the screening of antiyeast and antifungal components. The powder of fruiting body of each mushroom was extracted with petroleum ether, 80% ethanol, and distilled water in that order, respectively. The antifungal activity of each extract from 32 different mushrooms were tested. The petroleum ether or ethanol extracts from fruiting bodies of Boletus auripes, Leccinum extremiorientale, Gomphus floccosus, Phaeolus schweinitzii, Pycnoporus cinnabarinus and Marasmius maximus showed antiyeast activities. The ethanol extract of Gyrophora esculenta showed an antiyeast activity against Cryptococcus neoformans, and its minimal inhibitory concentration (MIC) was $600\;{\mu}g/ml$. The petroleum ether or ethanol extracts from fruiting bodies of Amanita citrina, Leccinum extremiorientale, Gomphus floccosus, Phaeolus schweinitzii, Pycnoporus cinnabarinus, Marasmius maximus and Gyrophora esculenta showed antifungal activities. The ethanol extract of Gomphus floccoscus showed an antifungal activity against Microsporum gypseum, and its MIC was $1,000\;{\mu}g/ml$. The ethanol extract of Gyrophora esculenta showed antifungal activities against Trichophyton mentagrophytes, Microsporum gypseum and Pyricularia oryzae, and theirs MIC were $300\;{\mu}g/ml,\;600\;{\mu}g/ml\;and\;600\;{\mu}g/ml$, respectively. The petroleum ether extract of Gyrophrora esculenta also showed an antifungal activity against Microsporum gypseum, and its MIC was $300\;{\mu}g/ml$.

Agaricales species form pileate-stipitate fruiting bodies and play important roles in maintaining the terrestrial ecosystem as decomposers, symbionts, and pathogens. Approximately 23,000 Agaricales species have been known worldwide, and 937 species have been recorded in the Republic of Korea. However, most of them were identified solely based on morphological characteristics that often led to misidentifications. The specimens collected from 2018 to 2020 in the Republic of Korea were identified based on phylogenetic analysis of the internal transcribed spacer (ITS) sequences. Their identities were confirmed by microscopic characteristics. As a result, 14 Agaricales species were discovered for the first time in the Republic of Korea. They belonged to nine genera: Agaricus, Calocybe, Cortinarius, Hygrocybe, Inocybe, Lepista, Leucoagaricus, Marasmius, and Psathyrella. Detailed macroscopic and microscopic descriptions were provided to help distinguish these species. The morphological and molecular data provided in this study will serve as reliable references for the identification of Agaricales species.

Macrofungi play important roles in forest ecology as wood decayers, symbionts, and pathogens of living trees. For the effective forest management, it is imperative to have a comprehensive overview of macrofungi diversity in specific areas. As a part of the National Institute of Biological Resources projects for discovering indigenous fungi in Korea, we collected macrofungi in Gayasan National Park from 2017 to 2018. These specimens were identified based on morphological characteristics and sequence analysis of internal transcribed spacer (ITS) or the nuclear large subunit rRNA (LSU) region. We discovered 17 macrofungi new to Korea: Butyrea japonica, Ceriporia nanlingensis, Coltricia weii, Coltriciella subglobosa, Crepidotus crocophyllus, Cylindrobasidium laeve, Fulvoderma scaurum, Laetiporus cremeiporus, Lentinellus castoreus, Leucogyrophana mollusca, Marasmius insolitus, Nidularia deformis, Phaeophlebiopsis peniophoroides, Phanerochaete angustocystidiata, Phlebiopsis pilatii, Postia coeruleivirens, and Tengioboletus fujianensis. We described their detailed morphological characteristics.

Seasonal production and nutrient concentrations of mushrooms in an Quercus acutissima forest were studied from 1999 to 2000. Thirty 2×2m quadrats were established randomly in the study area. 114 species of mushrooms were identified during the study period. Although mushrooms occurred from May to November in each year, the highest biomass production occurred in August. Seasonal dominant species was Lactarius violascens in June, R. bella and L. violascens in July, Marasmius siccus in August, Cortinarius tenuipes in September, Lepista nuda and C. tenuipes in October, respectively. Annual production of mushrooms in 1999 and 2000 were 84.8 kgDW·ha/sup -1/·yr/sup -1/ and 86.7 kgDW·ha/sup -1/·yr/sup -1/, respectively. Seasonal production was27.1kg/ha for July, 35.9kg/ha for August and 17.1 kg/ha for September, 3.7kg/ha for October, respectively. Seasonal dominant species in biomass was Russula alboareolata in June, R. bella in July, R. pseudodelica in August and September, Lepista nuda in October, respectively. R. pseudodelica showed the highest biomass in the study area, which is 17.5% of the total biomass. Average concentration of nutrients in mushrooms was 45.2mg/g for N, 1.5 mg/g for P, 29.6 mg/g for K, 0.2 mg/g for Ca and 0.8 mg/g for Mg, respectively, which were much higher than those in the leaf litter. Nutrients absorbed by mushrooms in 2000 was 4,163.1 g·ha/sup -1/·yr/sup -1/ for N, 130.1 g·ha/sup -1/·yr/sup -1/ for P, 2,568.2 g·ha/sup -1/·yr/sup -1/ for K, 12.4 g·ha/sup -1/·yr/sup -1/ for Ca, 68.5 g·ha/sup -1/·yr/sup -1/ for Mg, respectively.

Amanita hemibapha is a kind of mycorrhizal mushroom which has a relation with host plants and environmental factors. For the purpose of studying the relationship between environmental factors and mushrooms, in this study we conducted to investigate the soil physicochemical properties, the distribution of plants and the diversity of mushrooms in Gwangyang, Chungdo and Daegu. Soil texture in habitate of Amanita hemibapha was Sandy Loam and Sandy Clay Loam which contains a high rate of sand. Soil pH was approximately 5.0 in all study sites. Total nitrogen contents, C/N ratio and available phosphate($P_2O_5$) were the highest at the Chungdo. However, Gwangyang and Chungdo represent similar Cation Exchange Capacity(C.E.C) and Daegu has much less than other areas. Exchangeable cations, $Ca^{2+}$ content was higher at Gwangyang and Chungdo than Daegu and $Na^+$ content was the highest at Chungdo among three sites. Daegu has much $Mg^{2+}$ contents followed by Chungdo and Gwangyang. Interestingly, $K^+$ content listed in reverse order of $Mg^{2+}$ at Gwangyang, Chungdo and Daegu. The main woody plants in study sites are confirmed as Carpinus laxiflora, Quercus mongolica, Q. serrata and Pinus densiflora. Quercus species are found as a common species in three study sites. Lastly, 8 family and 12 species of mushrooms are emerged in Gwangyang, also 8 family and 12 species and 5 family and 10 species are found in Chungdo and Daegu, respectively. Amanita pantherina, Boletus edulis, Tylopilus felleus and Marasmius maximus, which found in study sites, are also kind of mycorrhizal mushroom same as A. hemibaph. By using correspondence analysis, Q. mongolica, Q. serrata, Q. variabilis and C. laxiflora are expected to as a host plant of A. hemibapha.
