FIGURE 1. PhyML analysis of the nuclear ribosomal ITS region. Collection locations where known are given by the US Postal code for states. GSM=Great Smoky Mountains National Park, Tennessee side; BC=Canada British Columbia; CR=Costa Rica; ENV=environmental sequence. Ecto=ectomycorrhizal root tip. Bootstrap values are given to the left of the supported node. Percent divergence calculations were calculated using all base pair differences (i.e., a 13bp insertion in CLO3549 and AGF21 was counted as 13 bp differences, not a single difference).
