Found on the same log as the previous 2 posts. While the yellow ones may be Xanthoria parietina - Maritime Sunburst, don't know if the whitish and the brownish ones are the same ? Kindly enlighten please.
Hi David, Thank you for sharing your photo of this lovely lichen community. I agree Xanthoria parietina. Also top right whitish one is a Parmelia. Similar size whitish one on left, and smaller one lower middle is a Physcia, probably P. adscendens. As well there is a marvellous collection of crustose lichens across the entire surface of the photo. Some look like Lecanoras (possibly including Lecanora pacifica) and there are other types as well here. -frog
Many many thanks for your speedy reply. I went to Iona again this morning but was able to relocate the same log. But took some others with a proper macro lens in lieu of yesterday's wide angle one. However, I relocated yesterday's blue morph snow goose out of a flock of 500.
