Bayesian phylogeny of Glomeromycotina virtual taxa (VT; SSU rRNA gene sequences). The relative abundance of reads derived from each VT is shown for mainland and island sites collectively and for each island separately (i.e., symbol areas sum to 1 within each column). Islands are ordered by increasing remoteness. Blue symbols indicate islands of oceanic origin; green symbols indicate islands of continental origin. VT containing sequences from known morphospecies (cultured) are indicated by an open symbol. A mean estimate of spore diameter could be calculated for some cultured VT (shown in barplot in right-hand panel)
