Christensenia produces enormous amounts of spores, up to 7,000 spores per sporangium. The synangia are radially arranged, a unique character among extant species, but quite common in fossil representatives of the order. Because of its radial synangia (an archaic character that is also found in fossil Asterothecaceae) Christensenia has been considered to be an ancient lineage, despite the lack of fossil evidence.
