Naming

Subspecies of "C. fragile" can only be distinguished microscopically.
Dead Man's Fingers Here's one to add to the invasive species list, though I'm not sure if on this beach it is. It's somewhat unclear to me if it's invasive on the Pacific coast of the US or not, but it is on the Atlantic. It is thought to have originated in the oceans near Japan.
