Healthy (Amance) or declining (Illwald) forests were compared. The &lt;em&gt;Phytophthora&lt;/em&gt; population in both was diverse and locally abundant. At least eight species were present at Amance and six at Illwald. At Amance &lt;em&gt;Phytophthora&lt;/em&gt; species had a localized distribution in water and low-lying soils. At Illwald distribution was more uniform apparently due to flooding events. Most often recovered were &lt;em&gt;P. citricola, P. gonapodyides&lt;/em&gt; and &lt;em&gt;P. quercina. P. gonapodyides&lt;/em&gt; was ubiquitous in water and colonized leaf debris. &lt;em&gt;P. quercina&lt;/em&gt; was widely distributed in soil but not abundant, and was found in sites that did not otherwise appear to favor &lt;em&gt;Phytophthora&lt;/em&gt;. No correlation was detected between presence of &lt;em&gt;Phytophthora&lt;/em&gt; in soil and health of trees. Unusual combinations of environmental factors may be required for resident &lt;em&gt;Phytophthora&lt;/em&gt; to have a detrimental impact on oaks. © 1999 Editions scientifiques et médicales Elsevier SAS.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Hansen, E.M.</style></author><author><style face="normal" font="default" size="100%">P.

The new species resembles &lt;em&gt;P. ilicis&lt;/em&gt; with homothallic, amphigynous antheridia and deciduous, semi-papillate sporangia, and has a related ITS-DNA sequence. Symptoms and host range are similar to &lt;em&gt;P. ramorum&lt;/em&gt;, cause of Sudden Oak Death and leaf blight and shoot dieback diseases in California and Oregon forests, although &lt;em&gt;P. nemorosa&lt;/em&gt; does not appear to cause wide-spread mortality of oak trees.&lt;/p&gt;</style></abstract></record></records></xml>
