Yeah, the K test can be hard to see on the surface of Aspicilia

If you scratch it open, it can be easier to see. Even if the medulla doesn’t react, the K+ from the cortex will bleed over onto it and be more visible sometimes. I’ve unfortunately had to resort to testing with P if I get apparent K- – P is more sensitive to stictic/norstictic acid complex in my experience. Blah. Why can’t lichens be more consistent??

Checked thallus with K. It gives K+something light (as much as can be seen on green-gray surface). Perhaps yellowish as is supposed to be with this species. A.laevata should be found in northern Wisconsin on acidic rocks, which are mostly the bedrock up north (Southern parts are covered with basic dolomites and mixed-acidity sandstone).
