Very nice photos, Doug!
On first glance, the center part of that first image struck me as being very similar to some lichens that grow in my area on rocks in the desert. I posted about them earlier this year,
here.
But on more careful study, I think I was misled by the general appearance of the yellow and white colors. The forms of the beasts look different, at least I think they do.
Any chance of getting a closer shot of the first one?

PS. I really like that third image, too. I've been looking at an old issue of "Wings" magazine (published by the
Xerces Society, an invertebrate conservation group). It has a picture of some tropical tree that looks a lot like this -- except that hidden in their picture is a cryptically colored mantid
and a cryptically colored spider! You haven't noticed any of that lichen moving around, have you?
. The first picture is lichen on a tree. The second shot is lichen I found on a Granite border stone in the cemetery surrounding a headstone dating back to 1887. The whole lichen on the rock was a good 12 inches in diameter 
. The third picture is Lichen on my wood fence (old wood). The field of view on the first and third image is about 2 inches and 1 inch on the second picture.
