Five species of the genus Xylaria are recognized on Malaysia materials: X. hypoxylon (L. FR.) Grev., X. allantoidea (Berk.) Fr., X. cubensis (Mont.) Fr., X. curta Fr. and X. grammica (Mont.) Fr.. The collection of Xylaria allantoidea from Malaysia is compared to the collection from Taiwan in morphological characters. The species are described their the host and cultural characteristics by a bright microscope and a scanning electron microscope.

Leaf spot symptoms were frequently observed on yam plants grown in the Yeoju area in Korea during a disease survey in 2008. A total of five isolates of Pseudophloeosporella sp. were obtained from the infected leaves of yam plants. All of the isolates were identified as Pseudophloeosporella dioscoreae based on their morphological and cultural characteristics. A phylogenetic tree derived from the internal transcribed spacer sequences of the fungal isolates showed that the fungus is distinctly separated from species in other related genera. P. dioscoreae isolates caused very tiny spots on leaves of yam plants two weeks after artificial inoculation which were similar to those observed in the field. This is the first report that Pseudophloeosporella dioscoreae causes leaf spot in yams in Korea.

Anthracnose symptoms severely occurred up to 50% on leaves of English ivy growing in greenhouses in Cheongwon area of Korea during disease survey in April, 2000. The symptoms developed as concentric spots with dot-like acervuli on leaves of the plant. A total of 24 isolates of Colletotrichum sp. were obtained from the spotted lesions and identified as Colletotrichum trichellum based on the morphological and cultural characteristics. Leaf spots similar to the original anthracnose symptoms were induced on the host leaves by artificial inoculation with the isolates of the fungus. This is the first record of C. trichellum causing anthracnose of English ivy in Korea.

Thirty-seven single spore isolates were obtained from specimens of ascomycetous fruiting bodies collected from Mt. Suri, Anyang in Korea. The fungal specimens and isolates were identified as Dumontinia tuberosa based on their morphological and cultural characteristics. This is the first record of this fungus occurring in Korea.

A fungal survey that targeted the tribe Arachnopezizeae (Hyaloscyphaceae, Helotiales) was conducted in Korea. One variety belonging to Proliferodiscus and one species belonging to Rodwayella are recorded for the first time from Korea. Proliferodiscus inspersus var. magniascus differs from P. earoleucus by its amyloid reaction in ascal apices and larger asci. Rodwayella citrinula is distinguished from other members of the genus by small ascospores and its occurrence on grasses. The descriptions, illustrations and cultural characteristics of the species are provided.

Anthracnose symptoms severely occurred up to 100% on leaves of May lily grown in four locations in Korea during a disease survey in 2001. The symptoms appeared as circular to irregular spots with brown to dark brown discoloration on leaves of the plant, and severely infected leaves blighted. A total of 35 isolates of Colletotrichum sp. was obtained from the spotted lesions and identified as Colletotrichum liliacearum based on the morphological and cultural characteristics. Leaf spots similar to the original anthracnose symptoms were induced on the host leaves by artificial inoculation with the isolates of the fungus. This is the first report that C. liliacearum causes anthracnose of May lily.

Leaf spot disease was observed in sesame (Sesamum indicum L.) during 2009 and 2010 in Korea. The pathogen was identified as Alternaria simsimi based on morphological and cultural characteristics. The morphological identification was well supported by phylogenetic analysis of the ribosomal DNA-internal transcribed spacer region. A. simsimi isolates caused spot symptoms on leaves and stems of sesame plants 2 wk after artificial inoculation, which were similar to those observed in the field. This is the first record of leaf spot disease in Korea caused by A. simsimi.

Cultural characteristics and phylogenic relationships were investigated and classified among collected strains in Pholiota spp. which contain P. adiposa, P. squarrosa, P. nameko etc. They were tested on the four different media (PDA, MCM, YM, MEA) and sawdust (Alder, Oak, Pine, Popular) substrates. There was a little variation according to the media and sawdust substrates, although PDA and popular sawdust substrate seemed to be better. Most strains showed white colonies, but some strains were brown. Mycelial growth length differed according to the strains. To classify species, the internal transcribed spacer regions (ITS) of the ribosomal DNA (rDNA) repeats from Pholiota spp. were amplified using polymerase chain reaction (PCR) and then sequenced. According to the analysis of ITS sequences, they were classified into five clusters. Their spacer regions were 644~700 nucleotides in length. The reciprocal homologies of each ITS region among these strains were ranged from 49.6~99.9%. The phylogenic analysis might give a criterion to classify species in the collected strains.

Nine species of genus Ganoderma different in cultural characteristics each other were separated by histo-anatomical differences. Differences among the species and geographic distribution of G. lucidum were also analyzed to provide the criteria for the classification of Korean cultivation or wild type strains. Korean cultivation and wild type strains were quiet different from other species as well as Taiwan and North American G. lucidum strains in histo-anatomical traits of Ganoderma. Pore color of Korean G. lucidum strains was less brown than those of Taiwan and North American strains. Shapes of pores were round or circular in Korean strains but ellipsoidal or angular in Taiwan or North American strains. Pore numbers of Korean strains were more than those(4~6/mm) of Taiwan or North American strains. Hardness of the pileus of Korean strains was much more than that of Taiwan or North American strains. Such characteristics of Korean strains were different from those of other species of Ganoderma. Korean G. lucidum strains could be classified into the other group because they had many different traits in growth characteristics of fruiting bodies and histo-anatomical characteristics from those of Taiwan or North American G. lucidum and other species of G. lucidum complex.

Grape fruits with blue mold symptoms were collected from house storages in different locations in Korea and were investigated for their association with Penicillium species. A total of 12 isolates of Penicillium were isolated from the collected fruits. Based on morphological and cultural characteristics and beta-tublin gene sequence data analysis, they were identified as P. bialowiezense, P. citrinum, P. echinulatum, P. expansum, P. solitum and unidentified Penicillium species. P. solitum was the predominant followed by P. expansum. P. bialowiezense and P. echinulatum were newly recorded in Korea. beta-Tubulin gene sequences could be used to distinguish each species of Penicillium and the molecular groups were correlated well with the morphological species. The unidentified species was supposed to be a new species, not previously reported in literature.
