Description
Summary:	Stem rot symptoms of Convallaria keiskei occurred sporadically in the herb exhibition field at Hamyang- gun Gyeongnam province in Korea. The typical symptom is water-soaking on the main stem, rotting, wilting, and blighting, which eventually leads to death of the plant. The sclerotia, which were white to brown in color, globoid in shape with size of 1~3 mm hyphal width of which was 4~9 μm, were formed over lesions and surface soil line. The optimum temperature for mycelial growth and sclerotia formation was 30℃ 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 Convallaria keiskei caused by S. rolfsii in Korea.
