Unlike &lt;em&gt;Pythium, Phytophthora&lt;/em&gt; was essentially monophyletic, all but three species forming a cluster of eight clades. Two clades contained only species with nonpapillate sporangia. The other six clades included either papillate and semipapillate, or semipapillate and nonpapillate types, transcending traditional morphological groupings, which are evidently not natural assemblages. &lt;em&gt;Peronospora&lt;/em&gt; was related to &lt;em&gt;P. megakarya&lt;/em&gt; and &lt;em&gt;P. palmivora&lt;/em&gt; and appears to be derived from a &lt;em&gt;Phytophthora&lt;/em&gt; that has both lost the ability to produce zoospores and become an obligate biotroph. Three other &lt;em&gt;Phytophthoras&lt;/em&gt; located some distance from the main &lt;em&gt;Phytophthora-Peronospora&lt;/em&gt; cluster probably represent one or more additional genera.&lt;/p&gt;</style></abstract></record></records></xml>
