Description

Found washed up with no other nereocysts around. The holdfast was completely gone so I think it may have been ripped/eaten and dislodged.

The blades were very patchy, so I think it’s possible it may have been reproductive although I couldn’t find any clear sori.

Found near tideline. Very decayed/damaged. Root-like holdfast no longer attached to anything. Seems to have some ulva and rhodophyta species tangled in it.

Although heavily damaged, the remaining blade near the stipe shows the 5 midribs that are characteristic of costaria costata.
