ABSTRACT
Basidiomycetous macrofungi play important roles in maintaining forest ecosystems via carbon cycling and the mobilization of nitrogen and phosphorus. To understand the impact of human activity on macrofungi, an ongoing project at the Korea National Arboretum is focused on surveying the macrofungi in unexploited areas. Mt. Oseo was targeted in this survey because the number of visitors to this destination has been steadily increasing, and management and conservation plans for this destination are urgently required. Through 5 field surveys of Mt. Oseo from April to October 2012, 116 specimens of basidiomycetous macrofungi were collected and classified. The specimens were identified to the species level by analyzing their morphological characteristics and their DNA sequence data. A total of 80 species belonging to 57 genera and 25 families were identified. To the best of our knowledge, this is the first study to identify five of these species-Artomyces microsporus, Hymenopellis raphanipes, Pholiota abietis, Phylloporus brunneiceps, and Sirobasidium magnum-in Korea.

One rare and interesting species collected from Seorak-san, Inje-gun; Yeonyeop-san, Hongcheon-gun; Daeam-san, Yanggu-gun, Gangwon-do; Pocheon-gun, Gyeonggi-do; Songni-san, Boeun-gun; Joryeong-san, Goesan-gun, Chungcheongbuk-do and Sobaeksan, Yeongju-si, Gyeongsangbuk-do is described and illustrated in detail. The species "Protodaedalea hispida Imazeki" and genus "Protodaedalea Iamzeki" has not been previously recorded in Korean fungal flora. The specimens have been deposited in the Herbarium Conservation Center of the National Academy of Agricultural Sciences.

Los hongos se encuentran difundidos en el medio ambiente y son contaminantes frecuentes de los alimentos, siendo éste, el medio más fácil y rápido de transporte. Sus efectos nocivos dependerán de las condiciones externas que se brinden para que ellos puedan producir toxinas que afecten la salud del consumidor y el deterioro de los productos finales. El objetivo fue la identificación de la flora fúngica que pudiese estar presente en una empresa procesadora de alimento. La muestra estuvo constituida por áreas y superficies de interés para la empresa: áreas de empaque, rodillos de secado, piso 1, piso 2, piso 3 y la azotea, ubicada en el estado Carabobo, Venezuela. Se tomaron un total de 19 hisopados, para ser sembrados en agar Sabouraud y 49 placas empleando la técnica de sedimentación con el mismo agar, posteriormente fueron contabilizadas las UFC/mm3. Para la identificación por género y especie de los microorganismos se emplearon diferentes métodos y técnicas como: Cinta Adhesiva Transparente, Tubo Germinativo, Microcultivos y Pruebas API 20C. Los resultados obtenidos arrojaron que el mayor número de UFC/mm3 aisladas correspondieron a Cladiosporum oxysporum, Aspergillus níger, Rhizopus Spp y a Cándida albicans
Fungi are found spread throughout the environment and are frequent contaminants of food, since this is the fastest and easiest means for transport. Their injurious effects depend on the external conditions provided so that they can produce toxins affecting the health of the consumer and deterioration of the end products. The objective of this study was to identify the fungal flora that could be present in a food processing company. The sample consisted of areas and surfaces of interest to the company: packing areas, drying rollers, floor 1, floor 2, floor 3 and the roof, located in the state of Carabobo, Venezuela. A total of 19 swabs were taken, which were sown in Sabouraud agar and 49 plates, using the sedimentation technique with the same agar; later, the UFC/mm3 were counted. For identification of the microorganisms by genre and species, different methods and techniques were used, such as: transparent sticky tape, germinating tubes, microcultures and* API 20C tests. Results indicated that the greatest number of UFC/mm3 isolates corresponded to Cladiosporum oxysporum, Aspergillus níger, Rhizopus Spp and Cándida albicans

Effect of the antifungal antibiotic gliotoxin on root-rot diseases caused by Fusarium solani and its influence on population of fungal flora in soil were investigated. Bean seeds were treated with different concentrations of gliotoxin before sowing. The results obtained from the green house application of bioagent indicated that soaking seeds in different concentrations of gliotoxin from 1μg/mL to 15μg/mL (for 60 minutes) significantly reduced the percentage of damping off and root rot as compared with control (pathogen only). Also 10μg/mL of gliotoxin was significantly decreased the population of fungal flora as compared with control.
