The new species &lt;em&gt;Phytophthora obscura&lt;/em&gt; sp. nov. is formally named based on phylogenetic analysis, host range, Koch’s postulates and morphology. &lt;em&gt;Phytophthora obscura&lt;/em&gt; is homothallic with paragynous antheridia and semipapillate sporangia. It is genetically closely related to &lt;em&gt;P.&amp;nbsp;syringae&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;austrocedrae&lt;/em&gt; and together these three species define a new &lt;em&gt;Phytophthora&lt;/em&gt; subclade 8d, with significant support for all genetic loci analysed including seven nuclear genes and the mitochondrial gene coxII. The morphological and ecological characteristics are very similar to &lt;em&gt;P.&amp;nbsp;syringae&lt;/em&gt;, and it is likely that &lt;em&gt;P.&amp;nbsp;obscura&lt;/em&gt; was not described earlier because it was identified as &lt;em&gt;P.&amp;nbsp;syringae&lt;/em&gt;. Artificial inoculations indicated that horse chestnut, kalmia, pieris and rhododendron might be hosts, and Koch’s postulates were confirmed for kalmia from which it was isolated. This pathogen was named after its elusive nature since it has to date rarely been detected in the US and Germany.&lt;/p&gt;</style></abstract></record></records></xml>
