Four species such as Amanita gemmata, Tricholoma aurantiipes, Panellus violaceofulvus, and Leucopaxillus septentrionalis which were found in Jeju Island, are first reported in Korea. Four species were identified with macro- and microscopic descriptions and distinctive characters are presented for each species. A. gemmata and T. aurantiipes were collected in evergreen broadleaf forest of Gwaneumsa and the former also founded in Manjanggul. P. violaceofulvus was collected in subalpine plants including Abies koreana and Carpinus laxiflora of Halla Mountain. And L. septentrionalis recorded in deciduous broadleaf forest of Tamla valley.

DOI : 10.4489/KJM.2012.40.3.132
This study was performed to isolate and identify the orchid mycorrhizal fungi (OMF) from roots of five species of terrestrial orchids in Korea; Cymbidium goeringii, Spiranthes sinensis, Calanthe discolor, Bletilla striata, Pogonia minor. DNA was extracted from isolated OMF and ITS region was amplified using primers, ITS1-OF and ITS4-OF. Four species of OMF belong to Tulasnellaceae and Sebacinaceae were identified; Tulasnella calospora, Tulasnella irregularis, Tulasnella sp., Sebacina vermifera.

Leaves of Lindera obtusiloba were collected from four sites in Gangwon Province, Korea. Endophytic fungi were isolated from the leaves and identified using ITS sequences of rDNA. Total twelve species belonging of endophytic fungi were identified; Alternaria alternata, Annulohypoxylon annulatum, Creosphaeria sassafras, Diaporthe eres, Discosia sp., Epicoccum nigrum, Glomerella acutata, Glomerella cingulata, Paraconiothyrium brasiliense, Pestalotiopsis neglecta, Phomopsis amygdali, Xylaria sp. The endophytic fungus, Phomopsis amygdali, was the most dominant species isolated from L. obtusiloba in this study and the fungal diversities varied in the different sites.

DOI : 10.4489/KJM.2012.40.3.145
Two strains Pleurotus eryngii KNR2312 and A8B10 (Na) which have good traits in cap quality and speedy growing were selected to breed a new strain carrying the two traits. KNR2312-2636-
(Ga) with 45.2 cap lightness and 6.5 quality was breeded by a consecutive inbreeding between KNR2312-derived monokaryons.
came from outcrossing between Ga and Na was backcrossed with KNR2312-derived monokaryons twice to improve quality in cap color and shape. Therethrough Ga5NaKNR2312-47KNR2312-
carrying lightness of 49.5, quality of 7.3 and weight of 95.1 g was selected. The selected strain possesses good quality and dark color of cap. Especially its edge is 24 mm thick, therefore it is not likely damaged during processing and distribution.

The lignocellulytic enzymes including a-amylase (EC 22.214.171.124), lignin peroxidase (EC 126.96.36.199), laccase (EC 188.8.131.52), xylanase (EC 184.108.40.206),
-xylosidase (EC 220.127.116.11),
-glucosidase (EC 18.104.22.168) and cellulase (EC 22.214.171.124) were extracted from spent mushroom compost (SMC) of Pleurotus eryngii. Different extraction buffers and conditions were tested for optimal recovery of the enzymes. The optimum extraction was shaking incubation (200 rpm) for 2 h at
-Amylase was extracted with the productivity range from 1.20 to 1.6 Unit/SMC g. Cellulase was recovered with the productivity range from 2.10 to 2.80 U/gf.
-xylosidase productivities showed lowest recovery producing 0.1 U/g and 0.02 U/g, respectively. The P. eryngii SMCs collected from three different mushroom farms showed different recovery on laccase and xylanse, cellulase. Furthermore, the water extracted SMC was compared to commercial enzymes for its industrial application in decolorization and cellulase activity.

Kim, Jun-Ho ;
The Korean Journal of Mycology, volume 40, issue 3, 2012, Pages 159~163
DOI : 10.4489/KJM.2012.40.3.159
This study was performed to investigate the biological activities of Hericium erinaceus fruiting body, including antioxidative, fibrinolytic, thrombin inhibitory and
-glucosidase inhibitory activities. The water extract of H. erinaceus was fractionated into hexane, chloroform, ethyl acetate, butanol and water fractions, and each of these fractions was individually assayed. The water extract showed high antioxidative activity at 87.78%. The water fraction showed the highest extraction yield at 35.68% (w/w). In the fraction activity tests, butanol and water fractions showed strong antioxidative activities at 87.91% and 92.27%, respectively. Assays for fibrinolytic activity indicated that only the ethyl acetate fraction has significant efficacy at 2.96 plasmin units/mL. The 10-fold dilution of hexane fraction showed high thrombin inhibitory activity, and
-glucosidase inhibitory activity at 77.67% and 90.53%, respectively. In conclusion, solvent fractions of H. erinaceus can be used as materials for the development of biofunctional foods to prevent cardiovascular diseases.

For development of new high-value Korean traditional fermented food by using bioactive fungi and bacteria, Nuruk, Makgeolli and Cheonggukjang were prepared by mold, yeasts and bacteria from Korean traditional fermented foods and their physiological functionalities were investigated. Aspergillus oryzae N152-1 Nuruk showed the highest antihypertensive angiotensin I-converting enzyme inhibitory activity(57.2%), and Makgeolli made by Saccharomyces cerevisiae Y111-5 and commercial JS Ipguk (solid cultures of saccharifying enzyme-producing mold) was showed 42.0% of anti-obesity
-glucosidase inhibitory activity. Among various Cheonggukjang, No 463 Cheonggukjang made by Brevibacterium iodinum NCDO 613(T) was showed the highest fibrinolytic activity (size of clear zone: 28 mm) and good anti-obesity
-glucosidase inhibitory activity.

We report morphological and physiological characteristics of newly isolated six kinds of yeasts which are new in Korean mycoflora. The yeasts were isolated from wild flowers in Daejeon city, Korea and identified by molecular analysis of the amplified internal transcribed space rDNA sequence or partial 18S rDNA sequence. Species of isolates were identified as Kuraishia capsulate, Lodderomyces elongisporus, Pseudozyma antarctica, Starmerella bombicola.

Kwon, Jin-Hyeuk ; Choi, Si-Lim ; Lee, Heung-Su ; Shim, Hong-Sik ;

Stem rot of perilla (Perilla frutescens var. japonica Hara) occurred sporadically in the exhibition field at Gyeongsangnam-do Agricultural Research and Extension Services in Korea. The infected stems are water-soaked, rotted, wilted and finally leads to the death of the whole plants. The sclerotia, 1-3 mm, white to brown, spherical, were formed on lesions and the surface of soil line. The optimum temperature for mycelial growth and sclerotia formation was
on potato dextrose agar and the hyphal width was 4-9
. The typical clamp connections were observed in the hyphae of the fungus. On the basis of mycological characteristics and pathogenicity to host plants, this fungus was identified as Sclerotium rolfsii Saccardo. This is the first report of stem rot on perilla caused by S. rolfsii in Korea.
