These are foliose lichens - that means they can be peeled from their substrate (although obviously we would never do that!) and they're kind of leafy. I'm pretty sure of the identification of all of them, but am prepared to be corrected . . . Just look at the different colours!
|Anaptychia runcinata - This beautiful bronze-coloured lichen turns green when wet.|
|On a stone at Ardnave - Physcia adscendens (white) amongst Xanthoria parietina (yellow). This beautiful lichen has 'eyelashes' or cilia visible through a hand lens. The Xanthoria is plentiful round Islay's coasts.|
|Physconia distorta (I think) with Physcia adscendens - on fence at Gruinart|
|Melanelixia subaurifera (I think) - same fence at Gruinart|
