Best tree from the maximum-likelihood analysis.
Numbers in circles indicate the nodes used for fossil calibration: (1) Paleopyrenomycites devonicus; (2) Chaenotheca sp.; (3) Calicium sp.; (4) Alectoria succinica or Parmelia ambra; and (5) Chaenothecopsis sp. Numbers above branches correspond to bootstrap support values and thicker branches show bootstrap support >70%.

Maximum clade credibility chronogram for the major groups of Ascomycota.
The chronogram is the result from the BEAST analysis of Scenario 4. Each node represents the mean divergence time estimate and bars show their associated 95% credibility interval. Numbers corresponding to dated groups shown in Table 3 are written above the nodes.
Figure 3.
Comparison of divergence ages in several Ascomycota clades.
The mean divergence time estimates and their associated 95% credibility intervals (y–axis) for selected nodes within Ascomycota for the 4 scenarios studied (x–axis) are represented. A: node 1, Ascomycota crown; B: node 2, Pezizomycotina crown; C: node 3, Pezizomycetes–“Leotiomyceta”; D: node 9, Lichinomycetes–Coniocybomycetes; E: node 10, Coniocybomycetes crown; F: node 19, Lecanoromycetes crown; G: node 20, Eurotiomycetes crown; H: node 33, Ostropomycetidae; I: node 43, Ostropales; J: node 46, Lecanoromycetidae crown; K: node 47, Lecanorales crown; L: node 41, Arctomiaceae.
