Maximum likelihood phylogeny based on 11 SSU rDNA sequences (2033 characters) of sphaeromyxids and related taxa. Sphaeromyxa lycodi forms a robust clade with S. kenti, which is a well-supported sister clade to the S. hellandi group. The sphaeromyxids form two robustly supported groups from node A (arrowed); one clade contains taxa with straight spores (blue box) and the other contains those with curved spores (green box). Figures at the nodes represent percentage bootstrap support values from 1000 samplings. Cystodiscus melleni is used as the outgroup and to root the tree.
