In the woods.

This one was actually in the woods. The woods are not too dark, but not too sunny either. The dominating species are oaks, but the understory is full of maple, and just about every one of them have this lichen on them. I like going there just to find some interesting shapes and forms (and colors) of this particular lichen.

I have a collection of this identical thing from the Smokies (by our mailbox, actually), and it seems to key as L. thysanophora, even the spores are right. But I’ll be d—-ed if I can find a fibrous prothallus anywhere on it. Is it just so well-developed that there is no growing margin left? Was this in a sun-exposed location? (Mine was.) Maybe that could account for the color difference?
