dark vinaceous on cap, yellow orange then orange on blued context in cap, bright orange on stipe, negative on context in stipe.

Another feature… red areas of context inside stipe.

I really think this one is vermiculosoides. But since I have not IDed this species previously, and there are look-alikes, I’m leaving the proposal as “promising” for now.

Found one other fruit body in the same general area. I’ll post this one also.

What about macrochemical tests? Those should resolve any doubt…
