Mazzaella splendens (Setchell & N.L.Gardner) Fredericq, 1994
Thallus is an undivided, cordate to lanceolate blade, to 40 cm, very rubbery, and usually an iridescent brownish or purplish red in colour. This alga has a perennial, fleshy holdfast out of which a 3-6 cm stipe grows. Northern specimens are smaller than those found from British Columbia south.
This annual (with perennial crustose base) grows on rock in the low intertidal of semi-protected to exposed habitats.
Mazzaella splendens is a red algae with separate male and female thalli and three different life history phases.
Most similar to Mazzaella flaccida (can be virtually indistinguishable in the field).
