I appreciate the positive feedback! I agree with you. It’s why I became involved with MO, too. Darvin, Douglas Smith, etc. were so helpful when I was just starting to learn mushrooms. Good stuff.

Thanks Jason.

IMO this is the best thing about MO. One potentially gets quick clarification on technicalities only understood by someone who is well versed in the vernacular.

Ah, I understand the confusion!

The squamules on the podetia, even if they are concentrated toward the base, are considered “secondary” or “podetial” squamules. I don’t see any primary squamules in these photos. You can best tell in the first photo. All squamules seen there are clearly attached to the base of a podetium.

Thanks Jason.

C. scabriuscula looks like a good proposal. The grainy podetia which are branched, often on the upper portions, matches.

The big lichen book says, about C. scabriuscula, “Primary squamules rarely seen.” My wife and I thought this means the leafy looking attachments at the podetia bases. That had led us away from scabriuscula. Is this the correct interpretation of “primary squamules?”

C. gracilis ssp. gracilis has the same overall shape, even the abundant squamules on the stalks, but not the branching (as you say), and most importantly it has a smooth continuous cortex. Yours is missing cortex completely in places and has granular to powdery surface in other places. The other one I’d consider is C. squamosa but it should never be granular.
