Striated feather moss
No interactions present.
Looks a bit like Hypnum cupressiforme to me but I don't know much about mosses so I could easily be wrong.
There's not enough detail to be sure
E.striatum would usually have a more bushy look. I agree that Hypnum sp. is a possibility but definite ID is not possible.
