Isolations from infected tissues and rhizosphere soil samples consistently yielded a &lt;em&gt;Phytophthora&lt;/em&gt; species. It was initially identified as &lt;em&gt;Phytophthora cinnamomi&lt;/em&gt; var. &lt;em&gt;parvispora &lt;/em&gt;Kröber and Marwitz by comparing morphological features with the original description and the internal transcribed spacer (ITS) sequences with those present in GenBank. A multigene phylogeny based on DNA sequence data from two nuclear (ITS and β-tubulin) and two mitochondrial (&lt;em&gt;cox&lt;/em&gt;1 and &lt;em&gt;cox&lt;/em&gt;2) gene regions combined with extensive morphological and physiological properties of these isolates, including the ex-type culture of &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; var. &lt;em&gt;parvispora&lt;/em&gt;, demonstrates that this taxon is unique and it is redesignated here as &lt;em&gt;Phytophthora parvispora&lt;/em&gt; sp. nov. Although morphologically similar to &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;,&lt;em&gt; P.&amp;nbsp;parvispora&lt;/em&gt; differs by its smaller-sized sporangia, chlamydospores, oogonia and oospores, higher oospore wall index, single-celled antheridia, higher minimum and maximum temperatures for growth and faster growth at optimum temperature. In the phylogeny, &lt;em&gt;P.&amp;nbsp;parvispora&lt;/em&gt; falls within &lt;em&gt;Phytophthora &lt;/em&gt;ITS clade 7a, grouped in a well-supported clade sister to &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;. In pathogenicity tests, &lt;em&gt;P.&amp;nbsp;parvispora&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; were equally aggressive towards &lt;em&gt;A.&amp;nbsp;unedo&lt;/em&gt; seedlings. The possible geographic origin of &lt;em&gt;P.&amp;nbsp;parvispora&lt;/em&gt; is also discussed.&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%">Scanu, B.</style></author><author><style face="normal" font="default" size="100%">Linaldeddu, B.

Following surveys conducted in three declining cork oak forests, a &lt;em&gt;Phytophthora&lt;/em&gt; species was consistently isolated from soil samples collected from trees displaying different level of decline. Based on morphological features, growth rates at different temperatures and analysis of DNA sequences of the ITS region, all isolates were identified as &lt;em&gt;Phytophthora cinnamomi&lt;/em&gt; Rands. This pathogen caused large brownish lesions on inoculated freshly cut branches of cork oak. It was re-isolated from all infected tissues. These findings represent the first report of &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; on cork oak trees in Italy.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue></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%">Scanu, B.</style></author><author><style face="normal" font="default" size="100%">Webber, J.

The causal agent was identified as &lt;em&gt;Phytophthora pseudosyringae&lt;/em&gt;, based on morphological and analysis of the internal transcribed spacer (ITS) sequences. Between 2011 and 2013, a survey assessed the frequency and nature of these &lt;em&gt;P. pseudosyringae&lt;/em&gt; infections. Mature trees of &lt;em&gt;Nothofagus&lt;/em&gt; with stem lesions caused by &lt;em&gt;P. pseudosyringae&lt;/em&gt; were found across England, Scotland and Wales. Additional symptoms such as twig blight and leaf necrosis indicated that aerial infection was occurring. Besides &lt;em&gt;N. obliqua&lt;/em&gt;, other hosts regularly encountered included &lt;em&gt;Nothofagus alpina&lt;/em&gt;,&lt;em&gt; Fagus sylvatica&lt;/em&gt; and &lt;em&gt;Vaccinium myrtillus&lt;/em&gt;. In pathogenicity tests involving inoculation of logs, &lt;em&gt;P. pseudosyringae&lt;/em&gt; was shown to be an aggressive bark pathogen of &lt;em&gt;N. obliqua&lt;/em&gt; and &lt;em&gt;F. sylvatica&lt;/em&gt;, but significantly less aggressive on &lt;em&gt;N. alpina&lt;/em&gt;. Foliage susceptibility and sporulation tests showed marked differences between the six host species tested. Leaves of &lt;em&gt;N. obliqua&lt;/em&gt; and &lt;em&gt;V. myrtillus&lt;/em&gt; were highly susceptible. Leaves of &lt;em&gt;N. alpina&lt;/em&gt; were moderately susceptible, those of &lt;em&gt;Rhododendron ponticum&lt;/em&gt; slightly susceptible and those of &lt;em&gt;F. sylvatica&lt;/em&gt; not susceptible at all. High levels of sporulation were observed only on inoculated &lt;em&gt;N. obliqua&lt;/em&gt; and &lt;em&gt;V. myrtillus&lt;/em&gt; leaves. This suggests that &lt;em&gt;P. pseudosyringae&lt;/em&gt; may sporulate heavily on &lt;em&gt;N. obliqua&lt;/em&gt; foliage in the field and that this inoculum initiates the aerial lesions observed on the shoots, branches and stems. The results also suggest that &lt;em&gt;P. pseudosyringae&lt;/em&gt; has the potential to pose a serious threat to &lt;em&gt;N. obliqua&lt;/em&gt; and other &lt;em&gt;Nothofagus&lt;/em&gt; species in their Southern Hemisphere native ranges.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record></records></xml>
