Three possible unrooted species tree of the four filamentous Ascomycetes and their support by different analyses. Steps refer to the fewest total number of state changes of all characters required for a particular tree topology. Compatible characters refer to the number of characters compatible with a particular tree topology (the number of steps for a compatible character equals to the minimum value for a particular tree topology compared to other topologies). Reconcile cost refers to the sum of reconcile cost for a particular tree topology as described in the text. The percentage under the classical genes refers to the bootstrap support.
