Looking closely at mine they look very similar, but mine has slightly serrate edges. I can't see those on yours.

The shape of the pinnae looks slightly different to me, you can see the edges recurve slightly, that may be due to the spore foming on the backs. You can see where the spore makes in lines from the centre veins where the grooves are.

This looks like yours, I can see some serrate edges, I wonder if there are slight variations.
