A. There was a faster rate of molecular evolution occuring among free-living fungal species compared to lichens.
B. Fungi coevolving with algae in lichens featured higher rates of nucleotide substitutions.
C. Higher rates of nucleotide substitution in mutualistic fungi were widespread across many sections of the genome.
D. The transition to mutualism accelerated the rate of molecular evolution for fungal species.
