A stem and leaf rot disease of English ivy(Hedera helix) was found in the flower market, Jeonju, Chonbuk province, Korea in July 2007. A Phytophthora species was isolated from the diseased part of the plant. Based on the mycological properties and pathogenesis the isolate was identified as Phytophthora nicotianae. The fungus produce ovoid sporangium which was ovoid to spherical which is noncaducous, papillate and averaged in dimension. Chlamydospores were abundantly produced on agar media and sized about 28.5 in diameter. The fungus was heterothallic and A1 mating type. Oospores were measured 23.3 in size. Optimum temperature for growth of the fungus was 25 to . Up to our knowledge, this is the first report demonstrating the stem rot on English ivy caused by P. nicotianae in Korea.
