Douglas State Forest

Nectria damaged Black Birch.  Bill Neill reminds me that is called Nectria galligena

One revived (by melting snow) bracket mushroom growing on a stump, about 3.5" wide.  Bill Neill identifies it as Lenzites betulina

Gills.  The spore print was pale beige.  The spores were very variable in size and hard to see under the microscope.

This sign speaks for itself.  Black Birch to the right.

Here is a portion of the trail.

It looks like the forest is regularly harvested since most of the remaining trees are small in diameter.
