Let’s call it Graphis scripta for the lack of alternatives.

The thing perches itself on just about anything flat around here, and is present in this observation. As for the substrate it’s on and that surrounds it – no one knows, and no one ever will. Something off-white and flat. There are no specialists who can figure this out, not on MO at this point (I dare to say it :) I can call it Dendrothele (my default name for everything whitish and flattish), or I can call it a Martian, and no one will call my bluff :) Graphis scripta is in there though – undeniable fact.

I see the Graphis in the third photo

the bluish thing. It’s entirely possible the white stuff is unlichenized. Which thing is this observation supposed to be about? Judging by the fact that the thumbnail photo has no Graphis, I assume it was supposed to be about the white thing.

And yes, my notes, while terse, left no room for doubt that I found Trentepohlia in the specimen I dissected.

Jason, this is specimen #9162012-4

Looks like you found some Trentepohlia there…

Jim Bennett confirmed it’s non-lichenized.

I am saving the specimen for the next available Dendrothele specialist…

I do not know a Dendrothele species specific to Carya.

If you want an answer I fear you have to stick to an optical help.
I am quite sure though about Dendrothele. Aleurodiscus is somewhat with a cap-like structure, at least effuso-reflexed in most cases. You cannot rule out a lichen wholly though. Good literature and microscope is the only advice I can give here.

I’m thinking it’s similar to observation 89326

This one is definitely on Hickory – Carya. These fungi seem to be pretty common around here. The big question is – are they all the same species or just similar looking?
