Time-calibrated phylogeny of the major lineages of Lecanorales (Lecanoraceae, Parmeliaceae, Ramboldiaceae, and Gypsoplacaceae), based on a six-locus dataset, dataset 1 (Singh et al. 2015). Cladoniaceae was used as outgroup (Arup et al. 2007, Singh et al. 2013). Mean node age, 95% highest posterior density (HPD) and posterior probability (PP) were mapped on the maximum clade credibility tree. The red circle indicates the calibration point, i.e. the split between Protoparmelioideae and Parmelioideae. Only the strongly supported nodes were considered for divergence time estimates. Geological times are indicated at the axis of the tree. The number of specimens per species is indicated in brackets in front of the taxon names. The scale at the bottom of the tree represents age in millions of years (Ma). Parmelioideae, Gypsoplacaceae, Cladoniaceae, Ramboldiaceae and Lecanoraceae clades are collapsed. In Parmelioideae, Miriquidica and Protoparmelia s. l. clades are collapsed at the species level.
