In the last post, I went to look for what was flowering along the A9, but much to my surprise I found that there were some unexpected lichens as well. Because the new part of the A9 near the Wildlife park has been built through woodland, there are still some older trees. There was a group of old aspens that I looked at.

The ecological survey before building the road must have checked these trees as two of them had a metal disc with a number attached - presumably to protect them from workmen with a chainsaw!
There were woodland plants like Wood Anemone and Common Dog Violet in the grass, but I wanted to see what lichens there were. On a fallen log was a lichen I had never seen before.
It looked like a series of dark brown lobes (leaves) with some lighter brown structures that look a bit like fingernails (they are apothecia - the spore producing parts). Looking more closely, there were lots of little peglike growths as well (they are called isidia and are another way a lichen can spread).

The lichen turned out to be Peltigera praetextata and it was growing on the trunk of a live tree as well.
