Low intertidal, on rock.
Tetrasporophyte phase, tetrasporangia present.
Identified to C. gardneri because there are ecorticate (lacking cortication) region between nodes, branch apices are forcipate (crab-claw-like) and tetrasporangia appear to be in whorls around the main axis.
Taxonomic note: Used to be in the genus Ceramium (Ceramium gardneri), but was recently moved to the genus Campylaephora.

On rock, mid-intertidal.
Common, and lower down in intertidal than most Pyropia blades. Didn’t bring this one back to section, but a number of other similar blades were sectioned and had two cell layers (Pyropia has one cell layer).

Attached to small rock, upper intertidal. Both life phases present (upright and crust).
Probably Mastocarpus alaskensis because it is often found higher in the intertidal and has been DNA barcoded at this park, but staying conservative with this ID because Mastocarpus are quite variable.

Growing on Calliarthron tuberculosum in the low intertidal zone.
New name not updated on iNat yet — this should be called Callilithophytum parcum now.

Reproductive, this specimen was producing tetraspores by meiosis (four spores in a sporangium shown in first photo). Spores produced in special structures called 'conceptacles' that look like white bumps on the body. One photo shows the uncalcified segment in between the calcified segments of the body.

On rock near waterline at a 1.0m low tide. Under a microscope, the filaments branch like an Acrosiphonia (from the long-edge of a cell, not the very top of a cell), and have the curved or 'hooked' cells that are more common in A. coalita than A. arcta. The tips of filaments are noticably dark, I suspect because they are very actively growing at this point in their season.
