Recognized by sight: Actually I think it is fungal and a lichen of some sort. Marking it as ‘Lichen’ should get some of the lichenologists to look at it.

This one can be hard to read. KOH has a habit of dissolving everything, especially with these tiny disintegrating thalli, making it just sort of K+ “dark” of some indeterminate greenish-blackish-brownish color. Ideally you would apply it carefully and watch the immediate reaction, disregarding the final color after it’s dissolved the cortex. If I’m right, there should be a split second where it is intense lemon yellow, unmistakable if you see it.

Thanks, glad I posted this one too. I’ll try some chemicals on it if I pass by there next week.

Definitely a Cladonia

Growing on wood/bark, entirely a mass of squamules beginning to disintegrate into corticate granules, no podetia… suggests C. parasitica. If so, it would have very strong K+ yellow reaction.
