FIGURE 4.

Lichen-associated fungal composition and phylogenetic tree of major fungal OTUs. (A) Composition of lichen-associated fungi at the class level along the vertical position of thalli. Positions of thalli in the colony and labels of subsection were illustrated in Figure 1B. (B) Bayesian tree of major OTUs (>0.5% relative abundance). Thick branches represent those that were conserved in Bayesian, ML, and MP analyses. Posterior probabilities and bootstrap values (>0.9 and >70%) were shown on corresponding branches (Bayesian/ML/MP). The tree was rooted with Cladochytrium replicatum (NG 027614, Chytridiomycota). Detailed information for relative abundance of classes and OTUs was included in Supplementary Tables S3,S4.
