Pholiota sp. were collected from the forest of Kangwon province (Mt. Samak, Mt. Odae and Kangwon National University Forest Experimentation) from the early of August to the end of October 1997. Among these fungi, Poliota adiposa was selected for culture experiment because it is suitable for edible mushroom. The Optimal temperature for the mycelial growth of Pholiota adiposa was in the range of $28^{\circ}C$ while that of fruit body formation was $15{\pm}1^{\circ}C$. Brown sugar as carbon source and soybean flour as nitrogen source were good for mycelial growth in commercial liquid culture. The fruit bodies of Pholiota adiposa were artifitially produced on plastic bottle including poplar sawdust and rice bran (4:1).

To elucidate the composition of phytosterols in the fruit body of Pholiota spp. 6 species(P. adiposa, P. aurivella, P. highlandensis, P. nameko, P. squarrosa and Pholiota sp.) were analyzed with Gas chromatography(GC). Pholiota spp. were contained campesterol, stigmasterol, and $\beta$-sitosterol as the major phytosterols.

This study was performed to obtain basal data for development of new functional food by using mushroom Pholiota spp.. Among several kinds of extracts, water extracts of Pholiota adiposa ASI 24027 showed the highest solid yield of 58.7%. Crude protein of Pholiota adiposa ASI 24015 and ${\beta}$-glucan contents of Pholiota adiposa ASI 24005 were 25.0% and 0.66%, respectively. K and Mg were also contained plentifully in the fruiting body of Pholiota adiposa ASI 24004 (3,649 mg and 138 mg/100g dried fruiting body, respectively). Amino acid and total fatty acid contents were similar between almost all of Pholiota spp..

Extracts from 63 kinds of Pholiota sp. fruiting bodies were prepared using water and methanol, and then their physiological functionalities were investigated. The methanol extracts from Pholiota adiposa PAD030 showed high fibrinolytic activity and those of P. adiposa ASI PAD-022 showed potential inhibitory activity of 76.8% against ${\beta}-hydroxy-{\beta}-methylglutaryl(HMG)-CoA$ reductase. The highest antioxidant and tyrosinase inhibitory activities were found in the water extracts of Pholiota sp. PSP-015 (72.7%) and methanol extracts of P. nameko PNA-024 (69.5%), respectively. However, superoxide dismutase(SOD)-like activity and elastase inhibitory activity were low in almost of the extracts. The HMG-CoA reductase inhibitor from the fruiting body of P. adiposa PAD-022 which showed the highest functionality was extracted maximally when powder of the fruiting body was shaked at $30^{\circ}C$ for 12 h by methanol and its HMG-CoA reductase inhibitory activity was 80.2%.

Five basidiocarps of Pholiota species have been collected from the areas of BubJu Temple for last two years, and identified to those of P. adiposa or Pholiota species. The taxonomy of these basidiocarps with the morphological aspects was compared with the analysis obtained from the polymorphisms of PCR-RAPD bands made after reacted with the random primers. The polymorphic variations were observed within the species of the basidiocarps, but not between genomic DNA's of the mycelia obtained and the basidiocarps. Several different bands made from the primers (28 and 36) in PCR-RAPD reactions were identified within the genus of Pholiota and speculated to be specific for the individual basidiocarp of P. adiposa collected. The primers employed here were considered to be very useful for distinguishing the individual isolates or basidiocarps collected from the fields. Also, the basidiospores were obtained from the sporeprints of the above basidiocarps as a simple agar and confirmed with observations of clamp connection under microscopes. The matings of them indicated the 'tetrapolar' type, being different from the 'bipolar' type reported by Japanese basidiocarps of P. adiposa or P. nameko. Based on our work, the edible fungi collected were speculated to be a new breeding resource for those of Pholiota commercialized in Japan.

Present experiments were conducted to determine the possibility of cultivation of 9 edible wild species selected among the higher fungi growing in Korea. In the investigation on the mycelial growth according t6o the different media, the mycelial growth of Coprinus comatus was fast on the CSA medium, when malt extract was added to the basal medium PSA, the mycelial of Lapista nuda and Auricularia auricula-judae was fast in growth and density. In the spawning, the mycelial growth of Pholiota squarrosa on the oak tree's sawdust, Pleurotus cornucopiae on the broad-leaves' sawdust, and Coprinus comatus on the compost was respectably fast and also it shown to be possibility of artificial cultivation owing to their carporphore budding when Coprinus comatus and Lepiota alborubescens cultivated on the rice straw, Auricularia auriculajudae and Pleurotus cornucopiae on the sawdust of the popla and Pholiota squarrosaon the sawdust of the oak tree.

This study was carried out to obtain new cancer metastasis inhibitor from mushrooms. Extracts from 52 isolates belong to 7 species of mushrooms were prepared by water, ethanol and methanol extractions and its anti-angiogenic activity were investigated by choriollantoic membrane(CAM) assay. Water extracts of Fomitella fraxinea ASI 17003 and ASI 17009 fruiting bodies, ethanol extract of Pholiota sp. ASI 24008 and Grifola frondosa ASI 9017 fruiting bodies and methanol extract of Inonotus obliquus ASI 74012 mycelia had the potential anti-angiogenic activity of 62.5%~68.8%. Finally, Pholiota sp. ASI 24008 was selected as a producer of cancer metastasis inhibitor on the basis of their solid yield and anti-angiogenic activity, etc.

To develop potent anitumor polysac-charides from higher hungi of Korea the alcohol precipitated polysaccharides, which were obtained from hot water extracts of shake-cultured mycelia of eight species of basidiomycetes, were subjected to antitumor screening tests, using sarcoma 180 as a tumor cell. When administered i. p, at the dose level of 20mg/kg/day for ten days into the mice which were implanted with $1{times}10^{8}$ cells of sarcoma 180 twenty-four hour before the start of polysaccharide injection, the polysaccharides of Plutcus cervinus ISA-Pc-1004, Pleurotus pulmonarius, Hydnum repandum ISA-Hr-1006, and Laccaria laccata ISA-LI-1008 respectively showed inhibition ratios of 62.0%, 51.7%, 64.8%, and 57.8%. They were selected for further study, while those of Pancillus serotina ISA-Ps-1012, Laccaria amethystina ISA-La 1001, Pholiota adiposa ISA-Pa-1010, and Lepista spISA-Ls-1007 respectively showed inhibition ratios of -9.3%, 25.3%, 27.3% and 33.0%.

This study was conducted to investigate the physiological activities of the ethanol extracts from 10 different strains of Pholiota nameko. In addition, the ${\beta}$-glucan and polyphenol contents from these strains were also measured. Total polyphenol contents from all the strains were more than 40 mg% with the highest content of $61.50{\pm}0.59$ mg% and ${\beta}$-glucan contents were 30% with the highest content of $37.20{\pm}1.12%$. The highest inhibitory activities on ${\alpha}$-amyloglucosidase activity and nitric oxide production were $13.78{\pm}0.56%$ and $56.59{\pm}7.11%$, respectively. However, ethanol extracts from all the strains have little effects on DPPH radical and nitrite scavenging rates and the activity of angiotensin I converting enzyme. The cytotoxic activity of ethanol extracts from all the strains on A549 cell was shown upto 30% with the highest effect of $47.96{\pm}8.46%$ treated at 1 mg/mL concentration.

Hispidin is a secondary metabolite found in numerous medicinal mushrooms that has attracted significant attention, owing to its distinct biological effects, including antioxidant, anti-inflammatory, antitumor, and cytoprotective properties. Experiments are being carried out to study the interaction of detonation nanodiamonds (DNDs) with synthetic and natural hispidin sourced from extracts of Pholiota sp. fungus. The bioluminescence method is used to determine the adsorption/desorption properties of DNDs toward hispidin. It is found that hispidin forms strong conjugates with DNDs, and the use of various eluents does not result in a significant release of the adsorbed hispidin molecules. DND-bovine serum albumin (BSA) complex, where DNDs serve as a carrier for the protein and the latter acts as a hispidin sorbent, has been developed and applied in hispidin adsorption/desorption tests. The results support the use of the DNDs as a carrier for hispidin in medical applications. They also advocate the application of the DND-BSA complex for isolating the substance from fungal extracts.
