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

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

    Likely ID
    rockloving lecidea lichen (Lecidea sp.)
    Confidence: It's likely to be this, but I can't be certain.

No (probably not)

I don't recognise this. (No surprise, there a huge number of crustose species I don't know, even when I should.) Whatever this is, I don't think it is Lecidea lithophila.

But one or two apothecia on the margin of the colony look ok, so perhaps it might be an odd form. Microscope needed, as is nearly always the case with a Lecidea or one of the allied genera.
