Thanks Chris - I have spent hours recently trying to update ZA LIchens - because I had no firm names - there was no way of sorting them and the very old links were useless.
But there is so much more happening with the dictionaries - just look at this - I’ve just got my head around Combea now I find Dufourea is also mentioned
