P. kernoviae&lt;/em&gt; was discovered in late 2003 during surveys of woodlands in Cornwall, south-west England, for the presence of another invasive pathogen, &lt;em&gt;P. ramorum. P. kernoviae&lt;/em&gt; is self-fertile (homothallic), having plerotic oogonia, often with distinctly tapered stalks and amphigynous antheridia. It produces papillate sporangia, sometimes markedly asymmetric with medium length pedicels. Its optimum temperature for growth is ca 18 $ınfty$C and upper limit ca 26$ınfty$. Currently, &lt;em&gt;P. kernoviae&lt;/em&gt; is especially noted for causing bleeding stem lesions on mature &lt;em&gt;Fagus sylvatica&lt;/em&gt; and foliar and stem necrosis of &lt;em&gt;Rhododendron ponticum. P. kernoviae&lt;/em&gt; is the latest of several invasive tree &lt;em&gt;Phytophthoras&lt;/em&gt; recently identified in the UK. Its geographical origins and the possible plant health risk it poses are discussed.&lt;/p&gt;</style></abstract></record></records></xml>
