Abstract

During routine vegetation health surveys in the southwest of Western Australia (SWWA), several Phytophthora isolates with affinity to Clade 6a have been recovered. In this study, all known taxa from Clade 6a, P. inundata, P. humicola, P. gemini, P. 'walnut' and P. 'personii', and the new isolates were compared based on morphology and DNA sequence data from three nuclear genes and two mitochondrial genes resulting in the description of five new species, P. balyanboodja, P. condilina, P. cooljarloo, P. kwongonina and P. pseudorosacearum. With the exception of P. gemini and P. humicola, all species from Clade 6a have been recovered from natural ecosystems in SWWA. These species are morphologically similar, with predominantly ovoid sporangia and nested and extended internal proliferation. If oospores are present, they tend to be aplerotic with paragynous antheridia mostly attached adjacent to the oogonial stalk. They can all grow at 35°C and have a fast growth rate on most agar media. These species have all been recovered from the rhizosphere soil and dead and dying plants within dry kwongon heathlands, often from water gaining sites and frequently from very isolated areas. The radiation, origin and potential ecological role of these species are discussed.
