DNA sequencing of the internal transcribed spacer (ITS) DNA and &lt;em class=&quot;a-plus-plus&quot;&gt;cox&lt;/em&gt;I gene confirm &lt;em class=&quot;a-plus-plus&quot;&gt;P. elongata&lt;/em&gt; as a distinct species within ITS clade 2. It has been isolated in the northern jarrah forest of Western Australia (WA) from the roots and collars of dead and dying &lt;em class=&quot;a-plus-plus&quot;&gt;Eucalyptus marginata&lt;/em&gt; and occasionally &lt;em class=&quot;a-plus-plus&quot;&gt;Corymbia calophylla&lt;/em&gt; in rehabilitated bauxite mine pits. It has also been associated with dead and dying plants of several mid- and understorey species in the northern and southern jarrah forest—&lt;em class=&quot;a-plus-plus&quot;&gt;Banksia grandis, Leucopogon propinquus, Dryandra squarrosa&lt;/em&gt; and an &lt;em class=&quot;a-plus-plus&quot;&gt;Andersonia&lt;/em&gt; sp., as well as the monocotyledonous &lt;em class=&quot;a-plus-plus&quot;&gt;Xanthorrhoea preissii, X. gracilis&lt;/em&gt; and &lt;em class=&quot;a-plus-plus&quot;&gt;Patersonia xanthina. P. elongata&lt;/em&gt; has also been isolated from sandy soils and loams in Victoria in eastern Australia. The pathogenicity of &lt;em class=&quot;a-plus-plus&quot;&gt;P. elongata&lt;/em&gt; to &lt;em class=&quot;a-plus-plus&quot;&gt;E. marginata&lt;/em&gt; and &lt;em class=&quot;a-plus-plus&quot;&gt;Banksia&lt;/em&gt; spp. has been shown in this and earlier studies. Due to the uniformity of the ITS DNA and &lt;em class=&quot;a-plus-plus&quot;&gt;cox&lt;/em&gt; 1 sequence data in WA, &lt;em class=&quot;a-plus-plus&quot;&gt;P. elongata&lt;/em&gt; may be the result of a recent clonal introduction. More pathogenicity tests on a wider range of native plant species are needed to assess the host range of &lt;em class=&quot;a-plus-plus&quot;&gt;P. elongata&lt;/em&gt; and its invasive potential in WA.&lt;/p&gt;</style></abstract></record></records></xml>
