DNA sequencing of the ITS rDNA and cox1 gene confirmed that &lt;em&gt;P.&amp;nbsp;arenaria&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;constricta&lt;/em&gt; are unique species residing in ITS clades 4 and 9, respectively. &lt;em&gt;Phytophthora arenaria&lt;/em&gt; has been isolated from vegetation occurring on the northern sandplains which are warmer and drier than the southern sandplains from which &lt;em&gt;P.&amp;nbsp;constricta&lt;/em&gt; has been predominantly isolated, and both species appear morphologically and physiologically well adapted to the ecosystems in which they occur. Both species have been associated mainly with dead and dying &lt;em&gt;Banksia&lt;/em&gt; species and the pathogenicity of both &lt;em&gt;P.&amp;nbsp;arenaria&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;constricta&lt;/em&gt; to &lt;em&gt;Banksia attenuata&lt;/em&gt; was confirmed in this study. The combination of unique DNA sequences, including considerable variation in cox1 sequence data, thick oospore walls and physiological characteristics that appear to be adaptations favouring survival in the harsh Kwongan ecosystem suggest that these species may be endemic to Western Australia.&lt;/p&gt;</style></abstract></record></records></xml>
