@ Tamlin:

Yes i thoroughly agree. Intermedia is certainly more glaborous.
I see your points now.
But i'll wait for more opinions from elsewhere before i make my final decision on it.

And is that Dr. Robert Gibson of the land of Oz? I certainly remember him and Fuzzy (with umlaut) from that trip in 08. Good luck to him on that voyage for identifying D. peltata.

Now Im going to try to sort our the mess i undoubtedly have upstairs...
