  • This study was conducted to investigate morphological characteristics of veiled lady mushroom (Dictyophora sp.). Morphological observation of mycelium showed the presence of chlamydospore-like swelling cells, and typical mycelial champ connections. Fruiting body of the veiled lady mushroom consists of cap, velum, stipe, and vulva. Oval-shaped eggs were surrounded by exodermis, gelatin layers and endodermis, and the fruiting bodies remained inside volva as liquid gelatin layer. Dark green spore layer was formed at the top of cap. The surface eggs in the cultivated veiled lady mushroom was covered with white needle-shaped mycelial projection that was oval in shape. The velum of fruiting body stretched down to the top of volva. The net was regularly shaped, and smelled like fragrance with chestnut flower. The strain KACC 50650 was identified as Dictyophora echinovolvata based on the morphology of eggs and fruiting bodies, and named as Huin-Dol-Gi-Mang-Tae mushroom in Korean.

  • To establish a genetic relationships of collected Ganoderma strains, mycelium growth according to media and temperature, colony morphology, chlamydospore formation and fruitbody morphology were investigated. For the identification of optimal growth conditions of the strains, five different growth media and four different temperature were tested. GCM (Ganoderma complete medium) at $30^{\circ}C$ was the most effective for mycelial growth of 68 strains with more or less variation. The strains were divided into 28 groups based on their colony shapes, and most of them belong to CM3 or CM8 group. Chlamydospores were observed in the mycelia of 16 strains including ASI 7022 on microscope, but not in most G. lucidum domestic strains, which showed relatively lagging growth on $35^{\circ}C$ in mycelial growth experiment. These results were not similar to those of G. lucidum but those of G. tsugae imported from USA. The strains were cultivated on oak sawdust media to see their fruit body formation. Ninety-seven among 115 strains formed fruitbodies in sawdust cultivation. They showed two forms of fruitbodies, 89.7% of flat type or 10.3% of antler type, although these shapes can be affected by $CO_2$ concentrations. These results suggest that the native strains formerly considered to belong to G. lucidum have to be re-classified with further study.

  • Phellinus linteus (Sang Hwang mushroom; P. linteusis) has been widely used for a traditional medicine in Japan, Korea and China. In traditional oriental applications, P. linteus and their extracts have been exclusively used to treat various diseases like insomnia, neurasthenia, gastric ulcers, arthritis, nephritis, stress, asthma, bronchitis, neuromuscular disorders, hypertension and also as an immune system stimulator in cancer therapy. In a number of articles, it is indicated how tremendous their therapeutic values are. According to these studies, P. linteus and their extracts show immunomodulatory activities like enhancing immune system function including anti-tumor activity and inhibiting the growth of existing tumors. P. linteus and their extracts have been being studied for use as immunotherapy agents and biological response modifiers (BRMs) for the possible treatment of cancer without side effects. Recently, the cultured mycelium product of P. linteus has been developed and approved as a medicine in Korea. This review shows not only the current status of methods of developmental technology like artificial culture and various biological applications of P. linteus but also recent market trends of functional foods made from P. linteus.

Genetic Analysis of the Life Cycle in Interspecific Hybrids of Pleurotus ostreatus and Pleurotus florida Following Protoplast Fusion (원형질 체융합에 의한 느타리버섯과 사철느타리버섯 체세포 잡종의 유전 분석)

  • Interspecific hybrids of Pleurotus ostreatus and Pleurotus florida were formed by using protoplasts of complementing auxotrophs. The genetic markers were shown to segregate and recombine in the first generation of monosporus isolates from basidiocarp of seven fusion products. The analysis provides proof of heterokaryosis and strong evidence for haploidy of vegetative nuclei, a sexual cycle consisting of nuclear fusion and meiosis. In all the crosses there was no evidence of linkage between the genetic markers. Clamp connections were formed in monosporus mycelia from basidiocarp of fusion products.

  • The biological activities of both ethanol and water extracts from the fruiting body of E. applanata and E. applanata mycelium and the three fractions of ethanol extracts from E. applanata were compared. 91% of MCF7 cell growth was inhibited by adding 0.5 g/l of water extracts of E. applanata and 81% of MCF7 cell growth was inhibited by adding 0.5 g/l of diethyl ether and chloroform fractions. It was also showed that above 60% of Hep3B cell growth was inhibited by adding all samples including the fractions. The ethanol extracts of E. applanata mycelium showed 33.3% of cytotoxicity on normal liver cell, WRL68 in adding 0.5 g/l of the samples and 40% in adding 0.5 g/l of chloroform fractions. The result of anti-mutagenicity of all extracts and fractions including ethanol extracts of Phelinus linteus were showed that diethyl ether fractions were most effective than any other samples. Hypoglycemic activities of diethyl ether and chloroform fractions were the most effective which scores were above 75%. The enhancement of glutathione-S-transferase activity was increased above 2.3 times by adding 1.0 g/l ethanol extracts of E. applanata and diethyl ether, chloroform fractions. It can be concluded that both biological activities of the fruiting body and mycelium of E. applanata were almost equivalent.

  • The Oyster mushroom is saprophytic fungus. The pileus is stemmed at the side and later depressed. It grows to 5-15 cm, and is of grey, grey-lilac, blackish-grey, steel grey, grey-brown, and blue-blackish. Various kinds of Oyster mushrooms such as golden, pink, brown, grey, white, and blue make marketing an interesting challenge depending upon the market niche. A new commercial strain "Chung" of oyster mushroom was developed by hyphal anastomosis. It was improved with hybridization between monokaryotic strain derived from Pleurotus ostreatus ASI 2194 and ASI 2487. The pileus of parental strain ASI 2194 and ASI 2487 was grey and light blue-grey, respectively. Most of intra-specific hybrids between strain ASI 2194 and ASI 2487 were showed similar pileus color of parents. By the way, the pileus color of variety 'Chung' was blue to bluish grey. The optimum temperatures of mycelial growth and fruiting body development was $25{\sim}30^{\circ}C$ and $12{\sim}16^{\circ}C$, respectively.
