Phylogenetic trees constructed by ITS (A) and COI (B) haplotypes. ITS and COI sequences from the same individuals are connected with lines. The dashed lines are Ophiocordyceps laojunshanensis. The pink, green, blue and red solid lines represent the four most abundant ITS haplotypes F01, F02, F03 and F04, respectively. Numbers above branches are Bayesian posterior probabilities shown as percentages (left) and bootstrap values calculated from the ML analysis of 1000 replicates (right). Haplotypes in a highlighted box are those delimited as representing “core” production regions in this study. The number of specimens of each haplotype sequenced is given in brackets. The yellow highlighted ITS (F01) and COI (H03) haplotypes are identical to the epitype designated by Li et al. (2021).
