eporcher's Identifications

Drift specimen, quite common. Body deteriorated, only a small portion of the blade left.
The papillae (bumps) had cystocarps, often 2-3 cystocarps per papillae. With this feature you can distinguish C. corymbiferus from the similar C. exasperatus.

Drift specimen, not common.
A red seaweed that appears quite brown, O. floccosa can be variable in morphology and hard to ID. This specimen is branching alternately and the branches lay flat (are in one plane).

Drift specimen, not common.
Brown seaweed, hollow tube, unbranched, with frequent constructions. Length ~ 20cm.
Think it fairly likely this is S. lomentaria because of the constrictions and published DNA barcode data for the area.

On rock, mid-intertidal. Near Scytosiphon lomentaria, Petalonia fascia, Ulva intestinalis.

Hard to see in photo, but short side branches arranged in a spiral or “winding staircase” way around the main axis. Often easy to confuse this genus with Odonthalia, but the overall stiff (not lax) thallus and short spiraling branches make me think this is most likely N. larix

On small rock, mid-intertidal (last photo shows location on beach).
Filamentous (polysiphonous construction visible with hand lens). Branches lay flat when spread out, helps distinguish from Polysiphonia.

No sign of reproduction.

On rock, mid-intertidal (second photo shows location). Fairly common.
Brown seaweed, hollow tube, unbranched, with frequent constructions. Length ~ 30cm for longest tubes.
Think it fairly likely this is S. lomentaria because of the constrictions and published DNA barcode data for the area.

On small rocks, rocks often buried in sand. Fairly common in mid-intertidal. Often next to Scytosiphon lomentaria.

Can tell this is not a baby kelp by, among other features, the small, discoid holdfast (young Saccharina and most other kelps in area with hapteral/root-like holdfast).

Kye Bay Beach, Comox.
