Phylogenetic tree generated from Bayesian analysis based on ITS sequences, showing the phylogenetic relationships of Balsamia. Tuber anniae and T. bellisporum are the outgroups. Maximum parsimonious bootstrap support values (≥ 70%) and maximum likelihood bootstrap support values (≥ 70%) are indicated above the nodes as MPBS/MLBS. Thick black branches received Bayesian posterior probabilities (BPP) ≥ 0.95. Novel sequences are printed in bold.
