Phytophthora isolated from different endemic locations were studied for morphological and molecular characterization using ITS, ITS-RFLP, MLST, SSCP and hybrid analysis. The isolates showed papillate, ovoid-obovoid sporangia with pedicel length > 20 μm which is distinct from the semi-papillate, caducous sporangia with short pedicel of <5 μm characteristic of P ramorum. The isolates failed to grow at 10 °C or at 37 °C and chlamydops...
