"Small & scattered oscula, dark color, not inhabited by barnacles: probably not S. confoederata. Also, all the S. confoederata I have found thus far that are small-medium sized are covered in porous disks, a la this observation: <a href="https://www.inaturalist.org/observations/26703131">https://www.inaturalist.org/observations/26703131</a>. This looks just like the Penares saccharis I have found at the channel islands. It could also be Penares cortius, which I have not yet found."<br />
