This study was carried out to investigate the effect of soil-born microorganism, vitabio on growth of leaf lettuce in the vinyl house. Total weights of leaf lettuce treated with vitabio showed difference compared with untreated leaf lettuce. Sugar content was also increased. Mineral contents of leaf lettuce showed no difference between treated with vitabio and untreated with vitabio. Exchange Capacity (EC) and Organic Matter (OM) in chemical properties of soil treated with vitabio showed higher than soil in untreated vitabio. Vitabio treated soil contained much more microorganisms such as Bacteria, Actinomycetes, Hyphomycetes, Bacillus sp. Pseudomonas sp. after harvest.

Cladophialophora is characterized by simple hyphomycetes with brown hyphae that give rise to branched chains of pale brown conidia and shows affinities with the Herpotrichiellaceae. A fungal strain belonging to the genus Cladophialophora was isolated from soil in Daegu, Korea. This strain produces numerous greenish to dark black lanose aerial mycelia with hair like structures. It is morphological similar to C. chaetospira, C. inabaensis, and C. multiseptata; however, the conidiophores and conidia sizes of the newly isolated strain (KNU16-032) are clearly different from them. The novelty of the strain was also confirmed based on phylogenetic analysis using the data sets of the internal transcribed spacer region of and the partial sequence of 28S ribosomal DNA region along with the cultural characteristics. Because morphological observations and phylogenetic analysis indicated that the strain is distinct from previously known Cladophialophora species, we propose this species as a new species Cladophialophora lanosa sp. nov., and provide the detailed descriptions in this study.

Asian Dust samples were collected in the ambient air of Seosan, Western Korea, in spring of 2000∼2002. PM (Particulate Matter) concentrations were 199,8$\mu\textrm{g}$/㎥ in the first Asian Dust period (March, 23∼24) and 249.4$\mu\textrm{g}$/㎥ in the second period (April, 7∼9) of 2000. Compared with the concentrations in 2000, relatively low PM concentrations, 157.3$\mu\textrm{g}$/㎥ were measured in the periods of 2001 (April, 24∼26). Especially high PM concentration 953.1$\mu\textrm{g}$/㎥ were measured in the periods of 2002 (March, 21∼22). The variation in the PM concentration was observed according to the time for the formation of Asian dust. Considering the particle size distributions of Asian dust, a high concentration was also observed in coarse particle region. The results of backward trajectory model showed the route of the dust storms from northern area of Mongol and Gobi desert. Various mycelia grown from fungal spores were observed on the PM samples and identified at the genus level. All the genera from the three years (2000∼2002), Fusarium, Aspergillus, Penicillium, Basipetospora, Epicoccum and Monotospora are hyphomycetes in the division Fungi imperfecti (Deuteromycota). Fungal composition on the dust sample in March, 2000 was similar to the result of March, 2002. However, the result of April, 2001 was obviously different from the other dust periods. The variations of fungal compositions between the dust periods could be caused by the trajectories of the dust storms.

Conidia of molds within the Asian dust were captured in the ambient air of mid-west Korea, in springtime of 2000~2002. An eight-stage Cascade impactor and 0.22 $\mu\textrm{m}$ pore size membrane filters were used for the dust samples. Several kinds of molds grown from the samples were identified to the genus level. Those are Aspergillus, Basipetospora, Epicoccum, Fusarium, Monotospora and Penicillium. Relatively diversified mycelia of hyphomycetes were grown on the fine dust sample (1.1~2.1 $\mu\textrm{m}$) in the first year Asian dust episode (23~24 March, 2000). On the other hand, some fluffy molds and dark molds aggregations were grown on even the backup particle sample less than 0.43 $\mu\textrm{m}$ during the second year episode (24~26 April, 2001). The result of the last year episode (21~22 March, 2002) showed various mycelia grown on the sample contained from 1.1 to 2.1 $\mu\textrm{m}$ sized particles, just like the result of the first year episode (23~24 March, 2000). These variations between the episodes might be caused by the difference of the dust origins.

A mycological survey was carried out with the soil samples collected in Korea from Sptember, 1978 to December, 1979. Special attention was paid fungus genus Penicillum. One hundred twenty three isolates, as a result, were obtained from the Korean soils. Among these, sixteen species were iedentified and described in this paper. Almost all of the fungi reported here are new to Korea. One of them is an asomycete cleisothecia of $120~50\mu$ in diameter. Ascospores of this fungus were found lenticular with an equatorial furrow as indicated in the previous descriptions.

Hirsutella subulata (Hyphomycetes) was observed for the first time on diseased larvae of Chilo suppressalis in Korea. This fungus formed slender and slightly attenuated synnemata consisting of closely bound, longitudinal hyphae on the insect larvae. Typical characteristics of this species are ellipsoid or broadly obovoid phialides with slender, needle-like necks and asymmetric conidia. It is very similar to H. barberi but can be distinguished by its asymmetrical conidia.

Forty-eight fungal isolates were collected from the Korean traditional maejus and twenty-eight isolates of them were identified to be a hyphomycetous fungus(three genera and 20 species) Aspergillus flavus, A. flavus var columnaris, A. oryzae, A, oryzae var effusus, A. terreus, Scopula­riosis brevicaulis, Penicillium botryosum, P. gorlenkoanum, P. griseo-purpureum, P. citrinum, P. miczynskii, P. gaditanum, P. turolense, P. funiculosum, P. rubicundum, P. godlewskii, P. jensenii, P. roqueforti, P. volguense, P. verrucosum. Various 14 species of Penicillium were isolated from maejus, but all of them were not considered to be involved in the maeju fermentation. Otherwise, S. brevicaulis was especially collected from the maejus of various located areas, but were also related to the good quality of maejus under labratory conditions. A. flavus, A. oryzae P. tulolense, and P. funiculosum were also observed to be involved in the process of maeju.
