The pathogenic fungus was isolated from diseased plants and the cultural and morphological chracteristic were observed. Conidia were rod in shape, 1-3 septa and 67.5-95.0×4.8-6.5 μm (av. 82.0×6.0 μm) in size. The optimum temperature for the mycelial growth of the isolates was 27oC. According to result the pathogenicity test, first disease symptoms appeared five days after inoculation. On the basis of mycological characteristics and pathogenicity test on host plants, the fungus was identified as Cylindrocladium spathiphylli. This is the first report on Spathiphyllum spp. caused by C. spathiphylli in Korea.
