Table 1 The fit of three alternative models of host evolution among decay fungi of Agaricomycetes. The best model (shown in bold), based on Akaike weights (w), was the model 3.3, which allowed only intermediate host transitions (“Correlated hosts”), no brown rot to white rot reversals (“norev”) and a root prior with equal probabilities among white rot fungi and zero probability for brown rot states (“white rot equal”). For model selection based on the exclusivity coding, see Additional file 1: Table S6
