Neighbor-joining tree inferred from ITS2 sequence comparisons (length, 276 nt). Desmodesmus serratus, D. lunatus, D. costato-granulatus, D. ultrasquamata, and D. elegans were used to root this tree. Numbers at each node represent bootstrap probabilities from NJ/ML (SYM + I + G model) analyses; only values above 50% are shown.
