Abstract
Two new species of non-colonial silica-scaled chrysophytes were discovered in Ontario and were assigned to the genusSpiniferomonas (Chrysophyceae) owing to their solitary cell habit. Scale structure in the two new species is distinctive but includes features common to bothSpiniferomonas andChrysosphaerella. The use of scale structure as the main diagnostic feature to distinguish the two genera is no longer acceptable. A more expedient separation of the two genera based on cell habit (solitary vs. colonial) is proposed and includes the transfer ofChrysospharella salina Birch-Andersen andChrysosphaerella coronacircumspina Wujek & Kristiansen to the genusSpiniferomonas as new combinations. The proposed revision is consistent with existing generic circumscriptions of other ochromonadalean forms with either solitary or colonial cell habit.
