Delesseria sanguinea is a common and bright red perennial alga with flat leaf-like red blades rising from a discoid holdfast. The blades are monostromatic, that is composed of a layers of single cells, and can grow to 25 cm long. Each blade rises from a cylindrical stipe, the stalk-like part, which branches only at near the base. Each blade may 8 cm wide and show a clear midrib with lateral veins. The tips of the blades are rounded.[1][2] Other similar algae include: Apoglossum ruscifolium, Hypoglossum hypoglossoides and Membranoptera alata all of which are much smaller.[2] Phycodrys rubens is of comparable size but can be easily distinguished having lobed edges to the blades.
