AbstractTwo new algal taxa are described from the approximately 2,000 m.y. old Gunflint Iron Formation, Ontario. Leptoteichos golubicii, n. gen. et sp., were relatively large (5-31 mu m) spherical plankters living in the water column above the central portions of the Gunflint basin. Post-mortem degradation processes have acted on this taxon to produce a "spot cell" organization similar to that exhibited by younger putatively eukaryotic cells; however, L. golubicii is here placed among the Algae incertae sedis and considered to be a probable cyanophyte. Megalytrum diacenum, n. gen. et sp., is the preserved sheath of a colonial chroococcalean blue-green alga. It constitutes an allochthonous element of the algal chert facies microbiota of the Gunflint Iron Formation.
