Dictyochloropsis reticulata is a species of green algae in the Microthamniales. It is a known as a photobiont (photosynthetic symbiont) with several lichen species, like Lobaria pulmonaria, but also as a free-living soil alga as well.[1] Phylogenetic analysis of rRNA sequence data revealed that the species shares a sister group relationship with two other green algae that lack motile stages, Chlorella saccharophila and C. luteoviridis.[2]
