Ectomycorrhizal communities in one region of origin of seagrape (Guadeloupe, after Séne et al. [30]) and sites from five regions of introduction, in percent of barcoded ectomycorrhizae. For each site, the numbers in brackets indicate the sampling effort, respectively, the number of soil cores and total number of ectomycorrhizae investigated. The diverse OTUs found in Guadeloupe are detailed in Table S2; Thelephora sp. #1 occurs in both Guadeloupe and Brazil
