Abstract

A recent study to determine the cause of collar and root rot disease outbreaks of cold tolerant Eucalyptus species in South Africa resulted in the isolation of two putative new Phytophthora species. Based on phylogenetic comparisons using the ITS and ?-tubulin gene regions, these species are distinct from known species. These differences were also supported by robust morphological characteristics. The names, Phytophthora frigida sp. nov. and Phytophthora alticola sp. nov. were thus provided for these taxa, which are phylogenetically closely related to P. mulitvesiculata and P. arecae, respectively. Phytophthora frigida is heterothallic, and differs from P. multivesiculata in producing stellate to rosaceous growth patterns on growth medium, corraloid hyphae, zoosporangia with a variety of distorted shapes and has the ability to grow at low temperatures. Phytophthora alticola can easily be distinguished from P. arecae by its slower growth in culture, and it is homothallic. Both Phytophthora frigida and Phytophthora alticola are pathogenic to Eucalyptus dunnii. They were, however, less pathogenic than P. cinnamomi, which is a well-known pathogen of Eucalyptus in South Africa.
