Jane, N albimarginatus seems to do OK here in UK in a raised bed in well-drained neutral soil which is somewhat shaded in summer and if N calcicola does well with you there's a good chance that albimarginatus would like similar conditions. I imagine it wouldn't like to be too dried out in summer. It's exciting that it seems to be thriving with you and others as it is somewhat threatened in the wild, more from collectors than a major change in its habitat. Good luck with pollination! In Portugal, I have seen N calcicola growing in pockets of leaf mould on limestone and I am sure, as you say, the soil is acidic.
