ABSTRACT Three new species and one new variety of Mallomonas (Mallomonadaceae, Chrysophyceae) were discovered in Ontario, Canada. Descriptions based on electron microscopy of silica scale structure are provided for Mallomonas inornata sp. nov., Mallomonas perfossa sp. nov., Mallomonas sexangularis sp. nov. and Mallomonas guttata var. simplex var. nov. The relationships of the scale structures of the new taxa with those known for other similar species are discussed. About 80 Mallomonas species and subspecies now are known from North America.
