Getting a permit

I’m in a process of getting a permit for this State Natural Area – hope to get some samples after that.

Definitely possible

The problem (for me at least) is that this set of Rhizocarpon (assuming it really is Rhizocarpon!) all looks the same to me. I’ve dissected quite a number in the last few months, and I’m frequently surprised by chemistry and/or spore differences hidden safely inside where the likes of us can’t see them. I think this is just one of those groups that require microscopy.

Maybe R.obscuratum?

R.hochstetteri doesn’t check out for Wisconsin. Could you check it against R.obscuratum? Some features, like growth pattern and black prothallus, seem to match. And even though color is described as ashy to rusty, the pics I’ve seen (Sharnoff) are actually greenish (but not as green as mine).

Very Christmasy!

There’s a few Rhizocarpon that look similar to this, like R. hochstetteri, I think it’s called?

The red rocks are really striking. What a cool effect.

Green circles

These lichen grow in deep shade. Alongside, there is whole panoply of other green crustose lichen on various rocks, so I tried to show the ones most likely belonging to the same species.
