Two new species belonging to the Synurophyceae are described from Orchid Bog Pond, a highly acidic, humic-stained bog, low in dissolved substances, situated in Newfoundland, Canada. Mallomonas baskettii has three types of scales, including highly asymmetric body and apical scales, and caudal scales with a small base plate and exceptionally long spines. Given the high degree of similarity of its scales with Mallomonas retrorsa, M. baskettii is placed in section Retrorsae, making it only the second species known for this section. It is further proposed that the description of a third species, M. fenestrata, be emended and that the taxon be transferred from section Quadratae to section Retrorsae. Synura kristiansenii sp. nov., placed in section Petersenianae, possesses scales with a large and variable-shaped median keel, and an enormous foramen pore on the base plate. Scales of Synura kristiansenii possess the largest foramen pore and median keel within the genus.
