Cyanidioschyzon merolae belongs in the red algae group.

C. merolae is a club-shaped, unicellular red alga that lives in highly acidic environments and in warm conditions.[1] C. merolae has a single chloroplast and a single mitochondrion, but lacks a vacuole and a cell wall.[2] The organism's genome was the first full algal genome to be sequenced in 2004;[3] its plastid was sequenced in 2000 and 2003, and its mitochondrion in 1998.[4] The organism is one of the most primitive red algae.[2]

Although possessing a small genome,[3] the chloroplast genome of C. merolae contains many genes not present in the chloroplast genomes of other algae and plants.[5] Most of its genes are intronless.[3]
