It can sometimes take a long time to identify lichens by yourself so it is really helpful when an expert shows you an unfamiliar lichen in the field and tells you what it is. Then all I have to do is take its picture, note it down, catalogue it and process it for the website - still time-consuming but so much easier!
I am very grateful to the following people for helping me in this way.
Also many thanks for people who have sent in photos:-
