  abstract = {{N}ew {C}aledonian serpentine (ultramafic) soils contain high levels of toxic heavy metals, in particular nickel, (up to 20 g kg−1) and are deficient in essential elements like carbon, nitrogen and phosphorus while having a high magnesium/calcium ratio. {A}lthough previous studies showed that ectomycorrhizal symbioses could play an important role in the adaptation of the endemic plants to ultramafic soils ({FEMS} {M}icrobiol {E}col 72:238–49, 2010), none of them have compared the diversity of microbial communities from ultramafic vs non-ultramafic soils in {N}ew {C}aledonia. {W}e explored the impact of edaphic characteristics on the diversity of ectomycorrhizal ({ECM}) fungi associated with different endemic species of {T}ristaniopsis ({M}yrtaceae) growing under contrasting soil conditions in the natural ecosystems of {N}ew {C}aledonia. {ECM} root tips were thus sampled from two different ultramafic sites ({K}oniambo massif and {D}esmazures forest) vs two volcano-sedimentary ones ({A}rama and {M}ont {N}inndo). {T}he molecular characterization of the {ECM} fungi through partial sequencing of the {ITS} r{RNA} gene revealed the presence of different dominant fungal genera including, both soil types combined, {C}ortinarius (36.1%), {P}isolithus (18.5%), {R}ussula (13.4%), {H}eliotales (8.2%) and {B}oletellus (7.2%). {A} high diversity of {ECM} taxa associated with {T}ristaniopsis species was found in both ultramafic and volcano-sedimentary soils but no significant differences in {ECM} genera distribution were observed between both soil types. {N}o link could be established between the phylogenetic clustering of {ECM} taxa and their soil type origin, thus suggesting a possible functional—rather than taxonomical—adaptation of {ECM} fungal communities to ultramafic soils.},
