Not sure which species this is so any comments will be great, thanks. Found on a sea defence boulder.
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.
According to the description, this is "on a sea defence boulder". According to the Location, this is between Rugby and Northampton.
Anyhow, Lecanora dispersa agg. on coastal rocks are tricky, perhaps especially so now the coastline has evidently moved. It might be true L. dispersa, but I am going with Thistle on this and agreeing to "agg.".
This was indeed taken near the coast on one of my travels, unfortunately I entered it as been from home!
