We used the ingrowth bag technique to sample the fine roots produced by each species in spring, summer, and winter. For each season, root architecture traits (specific root length, root diameter, root tips) and variables associated to root ectomycorrhizal status were measured in the laboratory. Results showed a marked seasonality in the fine root architecture, including more fine root tips and longer roots per unit of weight formed in spring and summer, revealing a capacity in Mediterranean oak species to modify root architecture in spring and suggesting the possibility of increased resource capture in summer. Fine root ectomycorrhizal status was comparable between species and also showed marked seasonality: we found a high percentage of roots colonized by dead ectomycorrhizas in winter but low ectomycorrhizal colonization rates in summer. Quercus ilex produced greater amounts of fine roots than Q. faginea (particularly during spring), suggesting greater competitive ability in the former species for belowground resources.</style></abstract><issue><style face="normal" font="default" size="100%">3</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%">Olivera, a</style></author><author><style face="normal" font="default" size="100%">Fischer, C.

Successful long-term management of a perennial plantation replacing an annual crop requires understanding the system in all phases of the life cycle, and in the case of trufﬂes this involves understanding the interactive growth of the aboveground host and the belowground symbiotic ectomycorrhizal fungus whose fruitbody is the desired trufﬂe. Here we focus on the pre-production phase, 4 years after establishing the trufﬂe-oak plantation and prior to trufﬂe production. We tested the inﬂuence of weed control, irrigation and fertilizer, each at 3 levels, on plant growth and ectomycorrhizal proliferation in three trufﬂe-oaks plantations in northeast Spain. Results show that adequate weed control improves root and shoot dry weight while fertilizer and irrigation treatments did not inﬂuence plant growth. The low dose of irrigation (50% of the estimated water deﬁcit for the site) and glyphosate weed control both increased total root tips/plant and T. melanosporum colonized tips (ectomycorrhizae) by approximately two-fold, compared to control treatments. Distribution of the ectomycorrhizae within the soil proﬁle was signiﬁcantly inﬂuenced by the low dose irrigation treatment, with increases observed in the 10–20 cm and the 20–30 cm deep layers compared to the control and high irrigation treatments. Four years after planting, T. melanosporum remained the dominant fungal symbiont, despite the presence of 14 other ectomycorrhizal morphotypes from these sites.</style></abstract><issue><style face="normal" font="default" size="100%">2</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%">Garcia-Montero, Luis G.</style></author><author><style face="normal" font="default" size="100%">Di Massimo, Gabriella</style></author><author><style face="normal" font="default" size="100%">Manjon, Jose L.</style></author><author><style face="normal" font="default" size="100%">Velazquez, Javier</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Description of Tuber malenconii mycorrhizae and a comparison with mycorrhizae of T. aestivum and T. mesentericum</style></title><secondary-title><style face="normal" font="default" size="100%">MYCOTAXON</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Ectomycorrhizae</style></keyword><keyword><style  face="normal" font="default" size="100%">hypogeous fungus</style></keyword><keyword><style  face="normal" font="default" size="100%">Tuberaceae</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2008</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2008///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">105</style></volume><pages><style face="normal" font="default" size="100%">407 - 414</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Tuber malenconii is a recently described uncommon European truffle associated with Quercus ilex that is potentially detrimental to the cultivation of the highly prized edible, T. melanosporum.

However, Chinese truffles could be introduced accidentally or fraudulently into the plantations of Mediterranean truffles, and they could have a negative effect on truffle production and natural ecosystems. The study of Tuber species from China which are commercialized in Europe began 14 years ago. Tuber pseudoexcavatum was proposed as a new species, and this has been validated by some authors based on molecular and phylogenetic studies. We synthesize their ectomycorrhizae using samples from the type collection, and we compare T. pseudoexcavatum and Tuber indicum ectomycorrhizae. The ectomycorrhizae of these species have a morphology which is related to the ectomycorrhizae of T. melanosporum. We provide useful information for the rapid screening of the above-mentioned Chinese truffles ectomycorrhizae, for the quality control of commercial plants mycorrhized with Tuber. Moreover, we analyze the soil tolerance and the host plant affinity of T. pseudoexcavatum and T. indicum, in order to assess the capacity of both Chinese truffles to penetrate T. melanosporum plantations and habitats.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 18813959</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Clavería, Vanessa</style></author><author><style face="normal" font="default" size="100%">De Miguel, Ana Mª</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Diversidad ectomicorrícica en una formación natural de carrasca (Quercus ilex L. subsp. ballota (Desf.)

Samp.) and to relate the above- and below-ground species diversity. The study area is the Nature Reserve of Monte del Conde, which has been proposed to be included in the Sites for Community Importance (SCI) and for Special Areas of Conservation (SAC) for the European Community. In autumn 2003, in an area of 225 m2, 374 sporocarps belonging to 52 taxa were collected. Clavulina cinerea (Fr.) Schroet., Entoloma rhodopolium (Fr.) Kumm. and Tricholoma scalpturatum (Fr.) Quél. were the dominant species. Belowground, morphological and anatomical analyses of ectomycorrhizal root tips were performed, yielding a total of 41 types. Cenococcum geophilum Fr. and thelephoroid fungi were dominant species on the root system. The preliminary results show that the sporocarps survey does not reflect the real ectomycorrhizal community diversity. Therefore, it is important to sample both sporocarps and root tips to achieve an accurate estimate of the ectomycorrhizal fungal community in forest ecosystems.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: IV Congreso Forestal Español&lt;br/&gt;issue: 1992&lt;br/&gt;pub-location: Zaragoza</style></notes></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%">De Roman, Miriam</style></author><author><style face="normal" font="default" size="100%">de Miguel, Ana María</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Post-fire, seasonal and annual dynamics of the ectomycorrhizal community in a Quercus ilex L. forest over a 3-year period.</style></title><secondary-title><style face="normal" font="default" size="100%">Mycorrhiza</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Annual variation</style></keyword><keyword><style  face="normal" font="default" size="100%">Ectomycorrhizae</style></keyword><keyword><style  face="normal" font="default" size="100%">Post-fire dynamics</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">seasonal variation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2005</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2005///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/15889285</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">15</style></volume><pages><style face="normal" font="default" size="100%">471 - 482</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Two study plots, burned and control, were established in autumn 1998 in a Quercus ilex forest located in northern Spain, part of which had been affected by a low intensity fire in 1994. Soil samples for ectomycorrhizae (ECM) were taken over a 3-year period in each study plot in spring, summer, autumn and winter. ECM morphotypes were identified and the relative abundance of each morphotype in each soil sample calculated, along with species richness, Shannon diversity index and percentage of mycorrhization in each soil sample. The relative abundance of certain ECM morphotypes differed between burned and control plots, and the percentage of mycorrhizal tips was significantly lower in the burned than in the control plot. Nevertheless, there were no significant differences in the diversity, species richness or species composition of the ECM community in the burned and control plots. The dominant ECM morphotypes in both stands were Cenococcum geophilum and several thelephoroid fungi. Sphaerosporella brunnea and Pisolithus tinctorius thrived especially in the burned plot, whereas three ectomycorrhizal morphotypes assigned to the genus Hebeloma were especially abundant in the control plot. There was no significant variation in the relative abundance of the ECM morphotypes between seasons, but ECM community species richness was highest in autumn and lowest in summer. The percentage of mycorrhizal tips reached a maximum in winter, with its minimum in autumn. Collection of samples over the 3-year period also enabled us to detect a significant increase in percentage of ECM colonisation in the burned stand over time.</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;accession-num: 15889285</style></notes></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%">De Roman, Miriam</style></author><author><style face="normal" font="default" size="100%">Clavería, Vanessa</style></author><author><style face="normal" font="default" size="100%">Maria De Miguel, Ana</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A revision of the descriptions of ectomycorrhizas published since 1961</style></title><secondary-title><style face="normal" font="default" size="100%">Mycological Research</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">descriptions</style></keyword><keyword><style  face="normal" font="default" size="100%">Ectomycorrhizae</style></keyword><keyword><style  face="normal" font="default" size="100%">habitat (PG)</style></keyword><keyword><style  face="normal" font="default" size="100%">host tree</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2005</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2005///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0953756208602324</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">109</style></volume><pages><style face="normal" font="default" size="100%">1063 - 1104</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">All available publications providing descriptions of ectomycorrhizas (ECM) were reviewed in order to build a database containing details on fungus forming the ECM, host tree, country where the material for description was collected, and habitat of the ECM.

Samp.) in Nazar and San Cristóbal (Navarra, Spain) has been carried out. In 1993 a stand in Nazar burnt, but it was not until 1998 that the study started. On the contrary, the study in San Cristóbal started immediately after the stand had caught fire in 2000. Therefore we have been able to compare the regeneration in both stands and the species composition five years after the fire and immediately after the fire, as well as the differences in ectomycorrhizal colonization and abundance of morphotypes between the burnt plots and areas which remained undisturbed in both forests, thus acting as control plots. In both sites the percentage of ectomycorrhizal colonization tended to be lower after the wildfire. In San Cristóbal, in the burnt site there was a lower abundance of morphotypes compared to the control site. However, in Nazar, five years after the fire, we did not find any significant change in species richness, but rather a shift in the abundance of each morphotype when comparing the burnt and the control plots. There are some species of mycorrhizal fungi which seem to be particularly adapted to fire, such as Type 1 in San Cristóbal and Cenococcum geophilum in Nazar. Sphaerosporella brunnea, a pioneer species considered to be especially suitable for the colonization of burnt substrates, was only found in Nazar.</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%">Román, D.
