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.
I can't see clearly enough to be 100% certain that the lobe tips are hooded rather than split which would identify it as P. adscendens rather than P. tenella

Cheers - could you explain a little further?
If you follow the two links you should be able to see the difference between the two species
Cheers Jenny - I see what you mean. Rather a lot to absorb with lichens, isn't there?
Yes, its hard as a lot of them are so small and can be very similar - having to remember Latin rather than common names doesn't help at all!
Habitat is important to note when trying to identify them as some lichens can be +/- habitat specific. Some only grow on trees, others are mainly found on either acidic or basic (e.g limestone) rocks and mortar so where they are growing can (sometimes) help narrow down ID possibilities.
