It was also found associated with necrotic fine roots and stem necroses of &lt;em&gt;Fagus sylvatica&lt;/em&gt; and &lt;em&gt;Alnus glutinosa.&lt;/em&gt; Due to morphological and physiological similarities, the semi-papillate isolates were previously identified as &lt;em&gt;P. syringae&lt;/em&gt; by various authors. The morphology, physiology and pathogenicity against fine roots of &lt;em&gt;Quercus robur, Q. petraea&lt;/em&gt; and &lt;em&gt;F. sylvatica,&lt;/em&gt; bark of &lt;em&gt;A. glutinosa,&lt;/em&gt; leaves of &lt;em&gt;Ilex aquifolium&lt;/em&gt; and apple fruits of this &lt;em&gt;Phytophthora&lt;/em&gt; species are described and compared with those of related and similar &lt;em&gt;Phytophthora&lt;/em&gt; species, namely &lt;em&gt;P. ilicis, P. psychrophila, P. quercina, P. citricola&lt;/em&gt; and &lt;em&gt;P. syringae.&lt;/em&gt; The phylogenetic placement on the basis of ITS and mtDNA sequence data was also examined. Isolates of this taxon produce colonies with stellate to rosaceous growth patterns and limited aerial mycelium on various agar media. Antheridia are predominantly paragynous. In water culture catenulate hyphal swellings and semi-papillate caducous sporangia, that are usually limoniform, ellipsoid or ovoid, are formed abundandly, mostly in lax or dense sympodia. This taxon is a moderately slow growing, low temperature species with optimum and maximum temperatures around 20 and 25 °C, respectively. Tested isolates are moderately aggressive to fine roots of oaks and beech, highly aggressive to holly leaves and apple fruits, and slightly pathogenic to alder bark. Thirteen tested isolates had an identical and distinct ITS sequence which was more similar to that of &lt;em&gt;P. ilicis&lt;/em&gt; and &lt;em&gt;P. psychrophila&lt;/em&gt; than any other known taxa. On the basis of their unique combination of morphological characters, colony growth patterns, cardinal temperatures for growth, growth rates, pathogenicity to oaks, beech, alder, apple and holly, their host range, and ITS and mtDNA sequences the semi-papillate caducous &lt;em&gt;Phytophthora&lt;/em&gt; isolates from oaks, beech and alder are clearly separated from related and similar &lt;em&gt;Phytophthora&lt;/em&gt; spp., and described as a new species, &lt;em&gt;P. pseudosyringae&lt;/em&gt; sp. nov.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">7</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%">Thomas Jung</style></author><author><style face="normal" font="default" size="100%">Nechwatal, Jan</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Phytophthora gallica sp. nov., a new species from rhizosphere soil of declining oak and reed stands in France and Germany</style></title><secondary-title><style face="normal" font="default" size="100%">Mycological Research</style></secondary-title><short-title><style face="normal" font="default" size="100%">Mycological Research</style></short-title></titles><dates><year><style  face="normal" font="default" size="100%">2008</style></year><pub-dates><date><style  face="normal" font="default" size="100%">10/2008</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">112</style></volume><pages><style face="normal" font="default" size="100%">1195 - 1205</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;A non-papillate, slow-growing &lt;em&gt;Phytophthora&lt;/em&gt; species, which could not be assigned to any existing taxon, was isolated from rhizosphere soil of a declining oak in Northeast France, and from the rhizosphere of &lt;em&gt;Phragmites australis&lt;/em&gt; at Lake Constance in south-west Germany in 1998 and 2004, respectively. We describe this species, previously informally designated &lt;em&gt;Phytophthora&lt;/em&gt; taxon ‘G’, as &lt;em&gt;Phytophthora gallica&lt;/em&gt; sp. nov. Morphology, growth rates, and pathogenicity against cuttings of riparian tree species and leaves of reed are described and compared with those of morphologically and phylogenetically similar &lt;em&gt;Phytophthora&lt;/em&gt; species. &lt;em&gt;P. gallica&lt;/em&gt; produces colonies with limited aerial mycelium and variable growth patterns. Gametangia are not formed in single or mixed cultures with tester strains of known mating types. &lt;em&gt;P. gallica&lt;/em&gt; produces globose and elongated irregular chlamydospores, of which a high proportion is abortive. In water culture irregular hyphal swellings and non-papillate persistent sporangia are formed abundantly. &lt;em&gt;P. gallica&lt;/em&gt; is moderately aggressive to &lt;em&gt;Alnus glutinosa&lt;/em&gt; and &lt;em&gt;Fagus sylvatica&lt;/em&gt;, weakly aggressive to &lt;em&gt;Quercus robur&lt;/em&gt; and &lt;em&gt;Salix alba&lt;/em&gt; and non-pathogenic to &lt;em&gt;Fraxinus excelsior&lt;/em&gt; and &lt;em&gt;Phragmites australis&lt;/em&gt;. According to ITS and mtDNA sequence data &lt;em&gt;P. gallica&lt;/em&gt; belongs to a distinct &lt;em&gt;Phytophthora&lt;/em&gt; clade, with &lt;em&gt;P. boehmeriae&lt;/em&gt; and &lt;em&gt;P. kernoviae&lt;/em&gt; being the closest relatives. The origin of &lt;em&gt;P. gallica&lt;/em&gt; and its ecological role in wet ecosystems remain unclear.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">10</style></issue></record></records></xml>
