The black spots have completely stopped showing up and the existing ones have sunken, dried out and don't seem to be doing anything now. I've had more root and leaf growth and I now have two flower spikes coming up!

Thanks for your help everyone.

Very cool! Lets see some pics!

If this were my plant, I would cut away the black area with a single-use single edged razor blade, and then dust the cut edge with cinnamon. If it is a fungal infection, it is probably local - for the moment. You don't want that infection to get into the rest of the plant, and cutting away the bad part (go a little into the clean tissue to be sure of getting it all) may well stop it in its tracks.
