Based on sequence of the internal transcribed spacer (ITS) region of the ribosomal DNA, 11 &lt;em&gt;Phytophthora&lt;/em&gt; spp. and two hybrid species were identified. A majority of the isolates were &lt;em&gt;P. citricola&lt;/em&gt; (35.9%) or &lt;em&gt;P. citrophthora&lt;/em&gt; (27.4%). Six isolates were confirmed as hybrids (four of &lt;em&gt;P. cactorum&lt;/em&gt; × &lt;em&gt;hedraiandra&lt;/em&gt; and two of &lt;em&gt;P. nicotianae&lt;/em&gt; × &lt;em&gt;cactorum&lt;/em&gt;) by cloning and sequencing the ITS region. Three &lt;em&gt;P. cactorum&lt;/em&gt; × &lt;em&gt;hedraiandra&lt;/em&gt; isolates were obtained from the same site, from three &lt;em&gt;Rhododendron&lt;/em&gt; spp., which are known hosts to the parental species. The fourth isolate, however, was recovered out of a different location in a &lt;em&gt;Dicentra&lt;/em&gt; sp., which is not a known host to either parental species, suggesting an expansion of host range of the hybrid isolate as compared with either parental species.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue></record></records></xml>
