Fig 1. Phylogeny of Protoparmelia sensu lato and its allies based on a concatenated 6-locus data set including ITS, nuLSU, mtSSU, MCM7, TSR1 and RPB1 sequences.

This is a maximum likelihood tree. Numbers above branches indicate ML BS ≥ 70%. Branches in bold indicate Bayesian posterior probabilities (PP) ≥ 0.94. Terminal clades were collapsed for clarity of presentation. The length of the triangle corresponds to branch lengths. Numbers in parentheses indicate number of specimens included in collapsed clade. Identity of each specimen in a clade is given in Supporting information S1 Table. Protoparmelia s.l. species are in bold.
