I think so

It certainly looks more convincing than my observation, which has the flattened, wider lobes of R. siliquosa combined with the blackened areas of R. cuspidata, and matches neither species description in the big flora.

Yes ...

both species are horribly variable.

I ducked agreeing with your observation, Nigel, but the mouths or the ostioles are definitly black, and not just shadow, and I think you were right.

Thank you...

yet again. That's reassuring. I was beginning to think about hybridisation. It's probably best that I just stop thinking and chill out.
