A red seaweed whose thallus is papery thin, rose red and a fan-shaped blade with fine veins radiating from near the base (though here it's tangled up). The blade is dissected into numerous lobes, which can be fringed with tiny bladelets.
Exposed at low tide near the West Point lighthouse, along the beach at Discovery Park. This perennial occurs on rock in the low intertidal to subtidal in semi-protected to semi-exposed habitats.
