Prior to this, &lt;em&gt;P.&amp;nbsp;foliorum&lt;/em&gt; had only been reported from foliage of hybrid azaleas in nurseries in California and Tennessee and from azalea plants in an ornamental nursery in Spain. No other hosts were known, and much of the behaviour of &lt;em&gt;P.&amp;nbsp;foliorum&lt;/em&gt; remained enigmatic. The species is classified in &lt;em&gt;Phytophthora&lt;/em&gt; Clade 8c, with closest relatives, &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; and &lt;em&gt;Phytophthora lateralis&lt;/em&gt;, both of which are highly damaging tree pathogens. To explore the threat that &lt;em&gt;P.&amp;nbsp;foliorum&lt;/em&gt; might pose to trees, its growth–temperature responses on agar media and ability to cause lesions in the living bark of various hosts were contrasted with the behaviours of &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;lateralis&lt;/em&gt;. &lt;em&gt;Phytophthora foliorum&lt;/em&gt; proved faster growing and more tolerant of temperature extremes than the other &lt;em&gt;Phytophthora&lt;/em&gt; species. Comparisons of bark colonization initially focussed on &lt;em&gt;R.&amp;nbsp;ponticum&lt;/em&gt; and larch species &lt;em&gt;Larix decidua&lt;/em&gt; and &lt;em&gt;Larix kaempferi&lt;/em&gt; as all three are significant hosts of &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; in the UK. Further experiments included another &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; host, &lt;em&gt;Fagus sylvatica&lt;/em&gt; (European beech), and the main host of &lt;em&gt;P.&amp;nbsp;lateralis&lt;/em&gt;, &lt;em&gt;Chamaecyparis lawsoniana&lt;/em&gt; (Lawson cypress). Findings suggested that as well as being a significant pathogen of &lt;em&gt;R.&amp;nbsp;ponticum&lt;/em&gt;, damage caused by &lt;em&gt;P.&amp;nbsp;foliorum&lt;/em&gt; to both species of larch and beech was very similar to that of the EU1 lineage of &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt;, although growth in host tissue was also influenced by season.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue></record></records></xml>
