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.
It appears that Dublin city is a major source of anthropogenic nitrogen pollution. Many of our shrubs, trees and all the rooftops are covered with this lichen. (Before studying lichens with the Open university I thought the yellow on the rooftops was crow droppings!)
So while a lack of fruticose lichens is a barometer of air quality, it appears that so is an abundance of Xanthoria sp.
except near the sea!
