Abstract
A stem and root rot disease of English ivy (Hedera helix) was found in the flower market, Jeonju, Chonbuk province, Korea in May 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 cinnamomi. The fungus produce ovoid sporangium which was ovoid to spherical and obpyriform which is noncaducous, non-papillate and averaged $33.8{\times}16{\mu}m$ in dimension. Chlamydospores were abundantly produced on agar media and sized about $19.7{\mu}m$ in diameter. The fungus was heterothallic and A1 mating type. Oospores were measured $26.2{\mu}m$ in size. Optimum temperature for growth of the fungus was 25 to $30^{\circ}C$. Up to our knowledge, this is the first report demonstrating the stem rot on English ivy caused by P. cinnamomi in Korea.
