The capability of higher ascomyceteous fungi to cause typical soft-rot decay for wood under laboratory conditions is reviewed and discussed. Fungi tested were extremely active in the decomposition of timbers. Scanning electron micrographs illustrated typical soft-rot decay pattern of higher wood decay ascomycetes, with the exception of H. trugodes that caused white-rot decay. Most of the fungi tested could be grouped as soft-rot fungi that showed typical soft-rot type II. Hypha confined primarily to the resin canals in softwoods or vessel elements in hardwoods and spread tracheid to tracheid via pits of cell wall to cell wall with mechanical force.

From April 2009 to October 2011, we surveyed the higher fungi in the Byeonsanbando National Park, Korea. In total, we identified 2 kingdoms, 3 divisions, 7 classes, 22 orders, 63 families, 149 genera, and 313 species (including 6 undocumented taxa: 2 families, 2 genera, and 2 species). Seventeen 17 orders, 49 families, 128 genera, and 286 species belonged to Basidiomycota; 7 orders, 9 families, 15 genera, and 21 species were of Ascomycota; and 4 orders, 5 families, 6 genera, and 6 species of primordial fungi. Among the Basidiomycota, Agaricomycetes were represented by 47 families, 126 genera, and 282 species. The most common fungi were Boletaceae (33 species), followed by Russulaceae (30), Agaricaceae (27), and Amanitaceae (24). Various species of most of the higher fungi occurred during periods with average temperatures of $23{\sim}24.9^{\circ}C$, maximum temperatures of $28{\sim}31.9^{\circ}C$, minimum temperatures of $22{\sim}22.9^{\circ}C$, > 82% relative humidity, and > 200 mm precipitation.

Free amino acids in extracts and total amino acids in hydrolysates of eight species of higher fungi were analyzed by an amino acid autoanalyzer. Twenty amino acids were analyzed in eight species of higher fungi. 1) of all free amino acids contained in higher fungi, alanine is the richest, and then comes glutamic acid, serine, arginine, proline and histidine in that order. Of all total amino acids contained in higher fungi, glutamic acid is the richest, and then comes proline, valine, aspartic acid, alanine, leucine in that order. Especially Russula fragilis and Lepiota procera contain large quantity of glutamic acid. 2) Gross contents of free amino acids in the extracts is high in order of Lepiota procera, Phylloporus rhodoxanthus, Russula fragilis, Tylopilus felleus and total amino acids in hydrolysates is high in Phylloporus rhodoxanthus, Lepiota procera, Russula fragilis, Lentinus lepideus. 3) Total amount of essential amino acids in the extracts was high in Lepiota procera, Phylloporus rhodoxanthus, Tylopilus felleus, Xylaria hypoxylon, Lentinus lepideus, Russula fragilis, Lactarius piperatus and Calocybe gambosa and in the hydrolysates of Phylloparus rhodoxanthus, Russula fragilis, Lepiota procera, Tylopilus felleus, Lentinus lepideus, Lactarius piperatus, Calocybe gambosa and Xylaria hypoxylon in that order, respectively.

To investigate the fungal flora in Korea, the basidio-mycetes and other higher fungi were collected in Seoul and Gyung-gi Province and examined for identification. Nine species and two varieties were identified and two of them, Agaricus xanthodermus Gen. and Lactarius nigroviolascens var. marginatus Smith & Hesler, were found to be unrecorded fungi. The total number of the higher fungi in Korea now exceeds 600 species including those reported during the past five years.

This study was conducted to investigate the diversity of higher fungi in NaeJangSan National Park from April 2004 to November 2006. The obtained results from investigation were as follows. The total of 5 classes, 19 orders, 60 families, 168 genera and 418 species (including 10 families, 13 genera and 15 species unrecorded) including saprophytic and ectomycorrhizal fungi was investigated. The higher fungi were classified into 47 families, 143 genera and 384 species in Basidiomycotina, 9 families, 19 genera and 28 species in Ascomycotina and 4 families, 6 genera and 6 species in Myxomycota. It was turned out that most of the higher fungi belong to Hymenomycetidae in Basidiomycotina, for which 34 families 122 genera, and 353 species were observed. Dorminant species belonged to Tricholomataceae(64 species) Russulaceae(39 species), Polyporaceae(36 species) and Boletaceae(36 species). The mushroom occurrence of higher fungi was closely related to climatic conditions such as high air temperature and lots of rainfall from July to September. The environment which has a favorable influence of mushroom occurrence was air temperature, relative humidity and rainfall of climatic environment.

Higher fungi were collected in the northern area of Kyungsangbuk-Do (Mt. Sobaek, Youngju, Andong and Koun Temple) during the period from April, 1974 to October,1978 and were identified. The total number of fungi were as follow: two classes, 10 orders, 32 families, 86 genera, and 149 species. These contained higher fungi which were published by Lee and Cho, 1976 (referred below with a special mark). Among them, Psilocybe merdaria (Fr.) Ricken, Laccaria galerinoides Sing., Conocybe tenera Var. subovalis Kuhner and Helotium sulphurinum Quel. were new fungi in Korea.

To investigate the fungal flora in Korea, the basidiomycetes and other higher fungi were collected and examined. Five species Coriolus pinsitus, Hirshioporus fusco-violaceus, Hymenurhaete intricata, Merulius tremellosus, Steccherinum ochraceum, were newly added to the list of previously recorded Korean higher fungi, the total amounting to 386 species.

The biodegradable characteristics of starch-filled polyethylene film by fungi were investigated. Aspergillus niger showed the highest cell growth among five species of fungi used in the experiment. Higher starch content gave the higher growth rate of A. niger; however, the kind of film or cutting direction did not give any effects on the cell growth. The use of vinyl trimethoxysilane for the stronger binding of starch and polyethylene did not inhibit the cell growth. When the starch content was higher than 10%, the elongation of the film decreased significantly after the growth of microorganism in the case of transverse direction samples.

Higher fungi (Basidiomycetes) were collected from forest stands of Kwangnung Experimental Forest, Kwangnung, Kyonggido, during the summer and fall seasons of 1976, 1984, 1985 and 1986. A total of 257 species and varieties in 104 genera were identified. Saprophytic fungi accounted for 135 species in 75 genera while mycorrhizal fungi accounted for 120 species in 28 genera. Two parasitic species were collected and they were root parasites. Among the mycorrhizal species Amanita, Russula, Lactarius, and species in the Boletaceae were the dominant taxa. The mycorrhizal fungi appear to be an important component in the essential elements needed for forest management in Korea. A reevaluation of the higher fungi previously described in Korea was made and we report 77 higher fungi previously undescribed from Korea. This is from a single experimental forest and suggests that there are many unreported higher fungi which play an important role in Korean forests.

A screening has been performed to find hyper-ligninolytic fungi, which degtrade beech and pine lignin extensively in order to broaden the understanding of the ligninolytic enzymes elaborated by various white-rot fungi. One hundred and twenty two ligninolytic strains were selected from decayed woods with a selective medium for screening ligninolytic wood-rotting fungi. Two of them, Phanerochaete sordida YK-624 and YK-472, showed much higher ligninolytic activity and selectivity in beech-wood degradation than typical lignin-degrading fungi, phanerochaete chrysosporium and Coriolus versicolor. They also degraded birch dioxane lignin and residual lignin in unbleached kraft pulp(UKP) much more extensively than P. chrysosporium and C. versicolor. During fungal treatment of beech wood-powder, the fungus strain P. sordida YK-624 showed higher activity of extracellular manganese peroxidase (MnP) in the medium than P. chrysosporium. It also showed MnP activity, which would not be lignin peroxidast during treatment of oxygen-bleached kraft pulp(OKP) and under enzyme-inducing conditin.
