Notes: Northern record: Roller Bay, Hope Island, British Columbia, Canada, UBC A48789. Southern records in California: Eel Point, San Clemente Island; La Jolla, San Diego Co., NCU-A-0002381.

Status: Confirmed by DNA sequence: Bodega Bay, Sonoma Co. (Lam & Zechman 2006).

Habitat: Low intertidal - subtidal, or in pools, on floats or other algae, often in exposed environments

Life History: Diplontic life history with diploid unisexual gametophytes developing directly from zygotes resulting from the fusion of anisogametes; gametic meiosis (Smith 1938).

Bryopsis Lamouroux 1809b

Thalli erect, usually densely branched but with few orders of branches. Branches mostly with percurrent axes, pinnately or radially branched. Chloroplasts numerous, discoid, with conspicuous pyrenoid. Thalli monoecious or dioecious, the gametes liberated through several pores in wall of gametangium. Zygote developing directly, without sporangial phase in life history.

Bryopsis corticulans Setch.

Setchell, P.B.-A., 1895-1919 [1903]: no. 626; Smith 1944: 73 (incl. synonymy).

Thalli mostly tufted, 5-10(16) cm tall, blackish-green; main erect axes to 1 mm diam., naked below, abundantly pinnately branched above; older branches with coarse, descending rhizoidal branches from their bases; ultimate branches 150-300 µm diam., cylindrical, abruptly constricted at base.

Frequent, on vertical sides of rocks exposed to strong surf, very abundant locally in fall as epiphytes on denuded branches of Egregia menziesii, midtidal to lower intertidal, S. Br. Columbia to Is. San Benito, Baja Calif. Type locality: Pacific Grove, Calif.
