This is on Betula lenta, staining/bruising readily the dark brown color of the snail trail. I am very familiar with this area if I need to go back to it.

it is a bit hard to tell, but it looks as if there’s a lot going on here … possibly more than one fungus. If you can return to the site and compare what you see to my OB # 198612 (Biscogniauxia atropunctata) it might help identify the underlying fungus which looks to me, at least from this photo angle, like an Hypoxylon Canker. The most common host is Oak, but it is also associated with hickory, maple, beech, birch (as you have identified here) and some others. There is a link in the reference section in my observation which might help you rule that in or out when you take another look.
Impossible to say without microscope data.
