Isolations from infected tissues and rhizosphere soil samples consistently yielded a &lt;em&gt;Phytophthora&lt;/em&gt; species. It was initially identified as &lt;em&gt;Phytophthora cinnamomi&lt;/em&gt; var. &lt;em&gt;parvispora &lt;/em&gt;Kröber and Marwitz by comparing morphological features with the original description and the internal transcribed spacer (ITS) sequences with those present in GenBank. A multigene phylogeny based on DNA sequence data from two nuclear (ITS and β-tubulin) and two mitochondrial (&lt;em&gt;cox&lt;/em&gt;1 and &lt;em&gt;cox&lt;/em&gt;2) gene regions combined with extensive morphological and physiological properties of these isolates, including the ex-type culture of &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; var. &lt;em&gt;parvispora&lt;/em&gt;, demonstrates that this taxon is unique and it is redesignated here as &lt;em&gt;Phytophthora parvispora&lt;/em&gt; sp. nov. Although morphologically similar to &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;,&lt;em&gt; P.&amp;nbsp;parvispora&lt;/em&gt; differs by its smaller-sized sporangia, chlamydospores, oogonia and oospores, higher oospore wall index, single-celled antheridia, higher minimum and maximum temperatures for growth and faster growth at optimum temperature. In the phylogeny, &lt;em&gt;P.&amp;nbsp;parvispora&lt;/em&gt; falls within &lt;em&gt;Phytophthora &lt;/em&gt;ITS clade 7a, grouped in a well-supported clade sister to &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;. In pathogenicity tests, &lt;em&gt;P.&amp;nbsp;parvispora&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; were equally aggressive towards &lt;em&gt;A.&amp;nbsp;unedo&lt;/em&gt; seedlings. The possible geographic origin of &lt;em&gt;P.&amp;nbsp;parvispora&lt;/em&gt; is also discussed.&lt;/p&gt;</style></abstract></record></records></xml>
