“…The highest ECM percentages were obtained in the fertilisation treatments, independently of the fertilisation method used. Spore inoculum of M. ambiguus has been previously used for inoculation of containerised conifers [24,32]. The improvement of M. ambiguus mycorrhization ability by fertilisation could indicate a different foraging strategy of this fungus with higher nutrient demands for hyphal development compared with the rest of fungi tested in our study.…”

-The influence of the fertilisation method: soluble (SF) vs. slow-release fertiliser (SRF) and of inoculation with Laccaria laccata (Scop.) Fr., Pisolithus tinctorius (Pers.) Coker & Couch and Melanogaster ambiguus (Vittad.) Tul & C. Tul. on ectomycorrhizal colonization and growth of Pinus pinea L. and Pinus pinaster Ait. was evaluated. For both pines, mycorrhization with L. laccata was not affected by the fertilisation method. Percentages of ectomycorrhizas (ECM) formed by P. tinctorius were dependent on the fertilisation method, the inoculum type (vegetative or spores) and the pine species involved. ECM formed by M. ambiguus were increased with fertilisation in both pines. Inoculation significantly improved P. pinea biomass when seedlings were fertilised with SRF whereas no effect was found in non-fertilised ones. For non-fertilised P. pinaster, inoculation with L. laccata and both inocula of P. tinctorius increased seedling biomass whereas fertilisation neutralised the fungal effect. Fertilisation increased P. pinea and P. pinaster biomass, independently of the inoculation treatment. Pour les deux pins, la mycorhization avec Laccaria laccata n'a pas été modifiée par la méthode de fertilisation. Le pourcentage d'ectomycorrhizes (ECM) formé by P. tinctorius dépendait de la méthode de fertilisation, su type d'inoculum (spores ou inoculum végétatif) et de l'espèce de pin. La fertilisation a augmenté les ECM produites par Melanogaster ambiguus chez les deux pins. L'inoculation a augmenté significativement la biomasse des semis de Pinus pinea lorsqu'ils ont été fertilisés avec SRF tandis qu'aucun effet n'a été trouvé pour les traitements non fertilisés. Pour les semis non fertilisés de Pinus pinaster, l'inoculation avec Laccaria laccata et avec les deux inoculums de Pisolithus tinctorius a augmenté la biomasse des semis tandis que la fertilisation a neutralisé l'effet de l'inoculation. La fertilisation a augmenté la biomasse de Pinus pinaster et de Pinus pinea indépendamment du traitement d'inoculation utilisé.Pinus pinea / Pinus pinaster / mycorhization contrôlée / champignon ectomycorhizien / pépinière de production de semis / fertilisation

“…Novel associations between nonnative planted trees and native fungi have been previously observed (Parlade´et al 1995, Jairus et al 2011, Trocha et al 2012, Bahram et al 2013), though not for P. menziesii in New Zealand (Chu-Chou and Grace 1987), but no prior studies of invasive trees have found novel associations with endemic ectomycorrhizal fungi (Dickie et al 2010, Nun˜ez and Dickie 2014, Bogar et al 2015. Novel associations in P. menziesii may, in part, reflect the tree's broad receptivity to a diverse range of fungi.…”

“…In fact, recent research has revealed that both co-invasion of nonnative mutualist species and novel associations with native species determine invasion success (Pringle et al 2009, Dickie et al 2010, Nun˜ez and Dickie 2014, Wood et al 2015. For example, ectomycorrhizal pines appear to invade only when co-invading exotic or cosmopolitan fungi are available (Nun˜ez et al 2009, Dickie et al 2010, Hynson et al 2013, Hayward et al 2015, though introduced trees may form novel associations with native fungi as adults (Parlade´et al 1995, Jairus et al 2011, Trocha et al 2012, Bahram et al 2013. These studies also demonstrate that the importance of co-invasion in conferring invasion success is variable among studies or taxa, but the reasons for this are unresolved.…”

Abstract. Biological invasions are a rapidly increasing driver of global change, yet fundamental gaps remain in our understanding of the factors determining the success or extent of invasions. For example, although most woody plant species depend on belowground mutualists such as mycorrhizal fungi and nitrogen-fixing bacteria, the relative importance of these mutualisms in conferring invasion success is unresolved. Here, we describe how neighborhood context (identity of nearby tree species) affects the formation of belowground ectomycorrhizal partnerships between fungi and seedlings of a widespread invasive tree species, Pseudotsuga menziesii (Douglas-fir), in New Zealand. We found that the formation of mycorrhizal partnerships, the composition of the fungal species involved in these partnerships, and the origin of the fungi (co-invading or native to New Zealand) all depend on neighborhood context. Our data suggest that nearby ectomycorrhizal host trees act as both a reservoir of fungal inoculum and a carbon source for late-successional and native fungi. By facilitating mycorrhization of P. menziesii seedlings, adult trees may alleviate mycorrhizal limitation at the P. menziesii invasion front. These results highlight the importance of studying biological invasions across multiple ecological settings to understand establishment success and invasion speed.

The morphology and anatomy of ectomycorrhizas of Rhizopogon arctostaphyli, R. ellenae, R. flavofibrillosus, R. occidentalis, R. rubescens, R. smithii, R. subcaerulescens and R. truncatus synthesized on Ponderosa pine (Pinus ponderosa) in glasshouse conditions using spore slurries, are described and compared. All species produced a well‐developed Hartig net, and a well‐developed fungal mantle. The mantles of R. arctostaphyli, R. smithii and R. subcaerulescens ectomycorrhizas were two‐layered with outer mantle hyphae of wider diameter than inner mantle hyphae. The mantle of R. subcaerulescens ectomycorrhizas also had distinctive peg‐like structures (cystidia) along peripheral hyphae. Rhizopogon truncatus ectomycorrhizas were tuberculate in morphology and had a rind‐like mantle enclosing adjacent roots. In addition, several species exhibited crystal inclusions in the outer mantle, presumably at the interface between mantle and soil.
