Lichens on Tree Branches

I have finally gotten out to the local botanic garden after a month long hiatus.  I went a couple of days ago on a bright sunny day.  Today, in the foggy gloom, I went again.  Both times, camera in hand.  The sunny day I was accompanied by a friend while this morning one of my dogs came along.

In today’s gloom, the bright green lichens on this tree caught my eye.  I’ve photographed it a number of times, in different seasons, under different lighting conditions.  There are spots of green, white, and dark grey.  Textures range from smooth to rough.  In the textures of the garden – leaves, flowers, critters, stems, branches, – it is easy to overlook the subtle beauty of a couple of branches.
