SUMMARY Seven isolates of Porphyridium from 2 species were compared. P. cruentum Naeg. isolates were similar in size and pigmentation; differences were observed among the P. aerugineum Geit. isolates. Differences were detected among isolates in reproduction, rate of movement, growth rate, and sensitivity to CuSO 4 and crystal violet. No isolate grew heterotropically; however, growth differences were apparent on various carbon sources.
