Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Your photo shows several crustose lichens. Lichen photography is generally agreed to be a challenge, and identification to species often requires more information than a photo alone can provide. However, as one of the stated aims of this website is to help people to improve their skills, I hope my comments will be useful, and that you will post more photos.
Habitat is often a useful for lichen identification; for example, is it growing on a rock, a tree trunk, tree branch, or on the soil?
If you look at Jenny's Irish Lichens site you will see, on the home page, examples of the other growth forms. http://www.irishlichens.ie/index.html. Jenny's and Alan's sites http://www.lichens.lastdragon.org/
are both recommended in the iSpot , and provide reliable information against which to check IDs. They also contain useful textual info on lichens.
Thank you that's really helpful
