Not rustyback

either A. adiantum nigrum or A, martimum first more likely

Agree with Mark, this is not Rustyback.

Fair enough - ferns are not a group I'm especially good at TBH... worth putting up a revised ID even if just to genus?

Genus ID

It's an Asplenium (but then so is rustyback - Asplenium ceterach).

If it was an inland site, I would identify your fern as Asplenium adiantum-nigrum. Turning to Stace, A. marinum is 1-pinnate, whilst A. adiantum-nigrum is 2-3-pinnate (in part). The yellowed frond is 2-pinnate at its base, so this would be A. adiantum-nigrum.

Asplenium

Thanks for the info - I might have to put some time aside to go out and dust off my fern ID!

Winter is a good time ...

... for fern spotting, as most common ferns are wintergreen (bracken and lady fern are prominent exceptions), and as much other vegetation has died back the ferns are more easily seen.

Garbled my sea spleenwort Latin!!
Rusty back fern was the first plant I ever identified on my own from CTW way back in the Pre-cambrian.
