Bayesian clustering of P. × cambivora-related isolates using STRUCTURE at K = 5. Each isolate is represented by a vertical line partitioned into coloured sections that represent the isolate’s estimated membership fractions in each cluster. Black lines separate isolates from different DAPC groups (see main text for details). The horizontal colour bar below the DAPC group name represents the colour used for that group in maps and supplementary figures. The mating type (A1 or A2) and ploidy level (diploid = 2n or higher) of each group is given below the plot and the geographic distribution of the group is given above the plot
