Supplementary Material 4. Percentages of basidiomycetous ITS1 (light blue columns) and ITS2 (light blue columns) sequences obtained from each soil sample following rarefaction to the same sequencing depth for both datasets (100 sequences per sample). Asterisks indicate a statistically significant difference between ITS1 and ITS2 for each sample [chi-square tests with Montecarlo simulation (5000 iterations); P <0.05].
