To understand host ranges and host specificity of ectomycorrhizal fungi and fungus specificity of host tree species, higher fungi from pure forest stands of following twelve tree species were collected for six years from 1981 to 1986: Pinus densiflora, P. rigida, P. koraiensis, Picea koraiensis, Larix leptolepis, Abies holophylla, Populus $alba{\times}glandulosa$, Castanea crenata, Quercus aliena, Q. acutissima, Q. mongolica, and Betula platyphylla. A total of 196 ectomycorrhizal species with 8 varieties in 48 genera were identified. Thirty-one species with one variety belonged to Russula, 22 species with 5 varieties to Amanita, 18 species with one variety to Lactarius. Fungi belonging to above three gepera, Laccaria, and Cantharellus had a relatively wide host range. Laccaria laccata was collected under all the 12 tree species, Amanita vaginata group under 11 tree species, Laccaria amethystina and Russula foetens under 10 tree species, Lactarius gerardii and Russula sororia under 9 tree species, and Amanita agglutinata, Cantharellus cibarius, Russula bella, and R. virescens under 8 tree species. Above 10 fungal species may be classified to have a wide host range. Following fungi were collected under 4 to 5 tree species of both conifers and broad-leaved trees: Amanita citrina, Boletus bicolor, B. erythropus, Lactarius piperatus, L. subzonar­ius, and Russula pseudodelica. Above fungi may be classified to have an intermediate host range. Chroogomphus, Gomphidius, Rhizopogon, and Suillus were collected only under Pinaceae and may be classified to have a narrow host range. Particularly Suillus grevillei was collected only under Larix leptolepis, and appeared to have high host specificity. A total of 83 ectomycorrhizal species were collected under Abies holophylla, 66 species under Pinus densiflora, 50 species under Pinus rigida, 49 species under Pinus koraiensis, 46 species under Quercus aliena, and 23 fungal species under Larix leptolepis. Particularly, Larix leptolepis was associated with different fungal flora, with fewer species of Amanita, Lactarius and Russula, and more species of Laccaria. Most host tree species surveyerl in the present study appeared to have low fungus specificity for ectomycorrhizal formation.

This study was performed to screen antimicrobial activities of 198 extracts from 66 Korean mushrooms against 19 human pathogenic microorganisms using paper disc method. Mushrooms were extracted with petroleum ether 80% ethanol and distilled water in that order Among the extracts with antimicrobial activities, 1 water extract of Amanita virgineoides, 8 ethanolic extracts including Amanita and 1 petroleum ether extrac of Psathyrella hydrophila were highly active against fungi, respectively. In addition to, 24 extracts including Amanita pseudoporphyria, Amanita spissacea, 3 extaracts including Paxillus curtisii were highly active against Gram negative and positive bacteria, respectively.

Ectomycorrhizal fungi in Pinus $rigida{\times}taeda$ and poplar stands (Populus $alba{\times}glandulosa$ and others) were collected in 1981 and 1982. A total of 39 mushrooms representing 15 genera were identified from the pine stand, and the major genera were Amanita, Lactarius, Russula, Laccaria, and Boletus. From the poplar stands 16 mushrooms representing 8 genera were identified and 13 of them were the same found in the pine stand. Amanita, Russula, Laccaria, and Leccinum are the major genera in the poplar stands. A single species of Boletus was found in large number in pine and poplar stands. Lactarius was not observed in the poplar stands, while Leccinum was not found in the pine stand. Cantharellus lutescens which has not been reported in Korea was collected in the pine stand.

Toxic effects of a mushroom, Amanita volvata, were studied in respect to biochemical and histological changes induced in the liver and kidneys of mice. The changes in biochemical parameters characteristically appeared 12 hrs after oral administration of an aqueous extract of the mushroom. The hepatic glycogen decreased markedly to 17% of the control level and a concemitant decrease in blood glucose was also observed. The activity of serum glutamic oxaloacetic transaminase (SGOT) was elevated by 2.5-fold and the level of blood urea nitrogen (BUN) increased by 3-fold, respectively, 12 hrs after administration of the mushroom, their levels being maintained up to 24 hrs.

This study was conducted to provide a fundamental information for commercial, medical usage and mushroom gene prezervation. The results of study are as following: 1. There were mushrooms of 53 families, 141 genus, 318 species at Mt. Palgong. 2. There were main edible mushroom of 63 species, main medicinal mushroom of 16 species, white rot fungus of 36 species and brown rot fungus of 4 species and Poisonous mushroom of 13 species at Mt. Palgong. 3. Poisonous mushrooms that are growing naturally at Mt. Palgong were Lampteromyces japonicus Sing, Amanita pantherina Krombh, Amanita phalloides Link, Naematoloma Krast and Amanita volvata Martin. 4. Numbers of mushroom species that are growing naturally at Mt. Palgong more than other regions.

Amanita virgineoides Bas is an ectomycorrhizal mushroom belonging to the family Amanitaceae in the order Agaricales. This fungus usually grows solely on damp soil in coniferous or deciduous forests from summer to autumn. Although Korean people consume A. virgineoides, some studies indicate that it can be poisonous. During our biodiversity survey of four specific regions i.e., Yongin, Eumseong, and Chungju from 2016 to 2018, A. virgineoides specimens were collected on the sixth rotation. We analyzed the temperature, precipitation, relative humidity, and vegetation surrounding the A. virgineoides fruiting bodies to reveal the environmental factors that influenced mushroom formation. It was found to usually grow in August, the hottest season in Korea. For 60 days before forming the fruiting body, temperatures were found to be between 20 and $30^{\circ}C$. More evidence is necessary to ensure that change in temperature is the major environmental factor that determines A. virgineoides fruiting.

To understand microorganism effects on wild mushroom fruiting bodies, we investigated the fungi in hyphosphere soil supporting wild mushroom species Cortinarius violaceus, Amanita hemibapha, Laccaria vinacelavellanea, and Amanita verna found in the Gotjawal area of Jeju Island. Fungal species identification based on morphological traits and molecular analysis of ITS, LSU rDNA, and β-tubulin gene sequences resulted in isolation and identification of eleven fungal species previously unrecorded in Korea. These newly-recorded species are: Arthrinium kogelbergensis, Kalmusia longisporum, Keithomyces carneum, Neopyrenochaeta cercidis, Penicillium ranomafanaense, Phomatodes nebulosa, Pyrenochaeta nobilis, Tolypocladium album, Talaromyces kendrickii, Talaromyces qii, and Umbelopsis gibberispora, and their morphological characteristics and phylogenetic positions are described.
