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

This isn't Hypogymnia physodes, which has a more tube-like, less leafy lobe structure.

I think it's a Punctelia species, but not sure which.

Edit: I'm more convinced by gardener's ID.

hi nigel & gardener thanks

hi nigel & gardener
thanks for your suggestions/corrections ... having looked on the EOL website, i'm inclined to agree with gardener too!
as i'm new to this whole lichen thing, i'm really grateful for your input - neither of your suggested names were in my (limited) books, so i now have increased knowledge!
many thanks

I made a mistake with that ID - I meant to put Platismatia glauca so I don't know what I was thinking of to have put Cetrelia instead!

(Oh where's an embarrassed Smiley?!)

Fairly similar-looking, but yes - that looks like an even better match! I have yet to see either species.

LOL Jenny, it's actually quite reassuring that there can be a crack (albeit an isolated one) in your usual efficiency.

again, thanks Jenny!
looking at other pics, that looks like the one ... interestingly, some of the other pics were taken close to here (north wales)!

Blimey Alan - You've got the wrong impression of me, I've never been very efficient though right now there are lots of cracks opening up!
