Nomenclatural code for fungi was dramatically modified in the 18th International Botanical Congress (IBC) held in Melbourne, Australia in July 2011. Its name was changed into International Code of Nomenclature for Algae, Fungi and Plants (ICN), which was formerly called as International Code of Botanical Nomenclature (ICBN) of the Vienna Code of 2005. The most important change for fungi is abandoning dual nomenclature and introducing one fungus/one name system (2013. 1). Since more than 10,000 species of fungal names should be renamed based on this new classification system (one fungus/one name system), it is challenging to both mycologists and taxonomic users such as plant pathologists and food scientists. Here, we introduced background, progress and future plan for its transition into one fungus/one name system. The new code is allowing electronic-only publication of names of new taxa (2102. 1) and the requirement for a Latin validating diagnosis was changed to allow either English or Latin for the publication of a new name (2011. 1). Furthermore, pre-publication deposit of key nomenclatural information in a recognized repository is mandatory in ICN (2013. 1). The aims of this manuscript are to introduce new code of fungal nomenclature and recent trends in one fungus/one name system to Korean mycological society.

URP primers that were derived from repetitive DNA sequence of rice weedy rice have been applied for producing PCR polymorphisms in different fungal species. URP-PCR protocol employed stringent PCR with high annealing temperature over
throughout the thermo-cycling reaction, giving high reproducibility. Under the PCR condition, Each single URP primer produced characteristic fingerprints from diverse genomes of different fungal species, indicating its universal applicability. URP-PCR has been accessed for applicability to various fungal species with 33 genus, 142 species and 1,489 isolates. Numerous related papers have demonstrated that URP-PCR profiles of fungal species are very useful for identifying fungal species at intra and inter species levels. The results were reviewed in this paper.

Halophyte samples, such as Suaeda japonica, Phragmites australis, Limonium tetragonum, Suaeda maritima were collected from Go-chang salt marsh. Thirty-nine endophytic fungal strains were isolated from the roots of halophytes naturally growing in salt marsh. All endophytic fungal strains isolated were analyzed by internal transcribed spacer (ITS) containing ITS1, 5.8 s and ITS2 region. Endophytic fungal strains belong to eight orders, i.e., Eurotiales (36%), Pleosporales (26%), Hypocreales (18%), Incertae sedis (8%), Glomerellales (5%), Sordariales (2%), Xylariales (2%), and Capnodiales (3%). On genus level, they were composed of Alternaria, Aspergillus, Chaetomium, Cladosporium, Colletotrichum, Coniothyrium, Dothideomycete, Fusarium, Gibberella, Macrophoma, Penicillium, Pestalotiopsis, Phaeosphaeria, Phoma, Pleosporales, Pseudozyma, Talaromyces, and Termitomyces. Of them, Penicillium (26%), Fusarium (13%) of Eurotiales and Hypocreales were predominant.

Gamma ray irradiation mutagenesis was employed to get variants of Pleurotus eryngii with functionally enhanced and improved characteristics. Protoplasts released from P. eryngii were treated with gamma ray radiation under 0.25-1.25 KGy. Protoplast sample that showed fatality rate of 80% at the 0.25 KGy was spreaded on YPMGA (yeast, peptone, malt-extract, glucose, agar) and 500 mycelial colonies were randomly selected from the medium. Of them, 100 mutant strains with mycelial morphology and growth rate that differ to control strain were observed on PDA. The cellulase and laccase activity of 67 gamma ray-irradiated P. eryngii isolates with morphological variation were investigated. Among these, 5 isolates were higher cellulase. In addition, the genetic variation of the mutant strains was analyzed by PCR fingerprinting.

This study has been conducted to screen the decolorization of 4 aromatic synthetic dyes and production of ligninolytic enzymes by 4 white rot fungi such as Bjerkanderia adusta, Cerrena unicolor, Pleurotus pulmonarius and Abortiporus biennis. It was found that B. adusta, C. unicolor, and P. pulmonarius have the ability to efficiently decolorize congo red and moderately decolorized amaranth and orange G in solid and liquid culture media. However, the decolorization rate of 4 synthetic dyes by A. biennis was relatively low. The decolorization of congo red, amaranth, orange G were related to the growth rate of the fungal mycelia in the solid medium. But, the all fungi tested did not efficiently decolorize methylene blue in the liquid culture media. To investigate the production of ligninolytic enzymes in media containing aromatic compounds, fungi were cultured in 1% naphthalene supplemented potato dextrose broth medium. All fungi tested had the capability to produce laccase, lignin peroxidase and manganese peroxidase, and B. adusta was the best ligninolytic enzymes producing white rot fungus among other fungi tested.

For development of new bioactive compounds from main edible mushrooms, we determined some physiological functionalities of water extracts from mushrooms. Among water extracts from some mushroom fruiting bodies, water extracts from Pleurotus ostreatus showed 73.2% of anti-hypertensive angiotensin I-converting enzyme inhibitory activity and 73.3% of anti-gout xanthine oxidase inhibitory activity, respectively. Fibrinolytic activity was also showed 21.5 mm of clear zone in water extract of Lyophyllum cinerascens. However, the other physiological functionalities were very weaked except 40.3% of antioxidant activity in Lentinus lepideus. Furthermore, the water extracts of Pleurotus eryngii and Lyophyllum cinerascens showed high anti-osteoporosis osteoclast differentiation inhibitory activity. However, the water extract from Lentinus lepideus and Pleurotus ostreatus were not detected any osteoclast differentiation inhibitory activity.

In order to develop environment friendly fungicide for the control of citrus green mold (Penicillium digitatum) using endophytic bacteria, the 21 bacterial isolates were isolated from citrus leaves in seven different orchards in Jeju Province. Among the 21 bacterial isolates, 5 bacterial isolates presented antifungal activity against green mold pathogen P. digitatum. The CB3 isolate, which showed the most strong antagonistic effect, was selected through opposite culture against the pathogen. The rod-shaped, gram-positive bacterium CB3 was identified as Bacillus velezensis based on morphological, physiological characteristics, 16S rDNA, and gyr A gene sequence analysis. The isolate CB3 showed strong antifungal activity against two citrus postharvest pathogen P. digitatum. Citrus fruits were treated by wound inoculation with P. digitatum pathogen, and the control efficacy of CB3 culture broth was 66.7% (
cfu/ml). In conclusion, The stability of CB3 and its strong antifungal activity also lead us to believe that it has potential for application as an environment friendly biological control agent.

Stem rot symptoms of Eupatorium lindleyanum occurred sporadically in the herb exhibition field at Hamyang-gun Gyeongsangnam-do Agricultural Research and Extension Services in Korea. The typical symptom included water-soaking on the main stem, rotting, wilting, and blighting, which eventually leads to death of the plant. The sclerotia, white to brown, globoid with size of 1-3 mm, were formed over lesions and surface soil line. The optimum temperature for mycelial growth and sclerotia formation was
on PDA. The typical clamp connections were observed in the hyphae of the fungus grown on PDA. Mycological characteristics and pathogenicity to host plants indicated that the infected fungus was Sclerotium rolfsii Saccardo. This is the first report of stem rot on Eupatorium lindleyanum caused by S. rolfsii in Korea.
