comparisons
Cystopteris fragilis Brittle Bladder Fern versus Asplenium adiantum-nigrum Black Spleenwort
Left: Cystopteris fragilis Brittle Bladder Fern versus
Right: Asplenium adiantum-nigrum Black Spleenwort
I guess for me the easiest way to identify the difference is by examining the pinnae and with the Cystopteris (Brittle Bladder) (above left) you note there is a central rib showing throughout each branch of pinnae, whereby on the Asplenium (Black Spleenwort) you do not see this central rib pronounced its more a question of equal small veins coming in from all directions towards the rachis. The opposing examples can be seen clearly in the above photos.
