I walked to lunch today, and paused along the way to take pictures of some of the lichens I saw.

There were only a few species represented (I assume, based purely on superficial appearance, which my brother tells me is not actually a good way to identify lichens).

A closer look.
I assume the large blue-grey lichen is a different species from the tiny blue-grey lichen also visible on the trunk, but what do I know about lichens?

I also saw this handsome moss along the way:

Someone on Twitter was just mentioning that the fact of their easy visibility in winter is one of the best things about lichens.
