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.

Note about spot tests

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

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.
