Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Not Flavoparmelia caperata

The photograph appears to show a crustose rather than a foliose lichen. From the bluish colour it could be a Lepraria sp.

It doesn't help being frozen, many thanks will change it, I had a huge debate as to wether it was algae but no.

Not an identification!

My comment above was just a suggestion and not a definite identification!

Would it be possible to post a clearer photograph that would show more detail?
