Hjelmqvist], in Oregon was recently observed. Most of the symptomatic or dead trees were located near roads. The cankers on the lower boles of trees are similar to those caused by species of &lt;em&gt;Phytophthora&lt;/em&gt; on other trees in western North America. The cankers in the inner bark were reddish-orange in colour and extended upward from necrotic roots. &lt;em&gt;Phytophthora&lt;/em&gt; (Petri) Buisman was isolated from the cankers; identity was confirmed by morphological comparison with known isolates and internal transcribed spacer sequence analysis. Pathogenicity was confirmed by inoculation of &lt;em&gt;chinquapin&lt;/em&gt; seedlings and mature trees. Seven of nine isolates from &lt;em&gt;chinquapin&lt;/em&gt; were A2 mating type; 27 of 28 isolates from other hosts in Oregon and Washington were A1 mating type.&lt;/p&gt;</style></abstract></record></records></xml>
