the shape here is a perfect match for Xylaria — clavate w/ a nearly right angled “stipe” just past the point of attachment — as is the occurrence on wood, hollow interior (not a genus-wide character, by any means), apparent firm-fleshy to coriaceous consistency, plus there looks to be a layer of black forming just beneath that yellow surface (visible in the cross section image), which are likely young, developing perithecia.

Clavariadelphus would be less broadly clavate or broadly clavate but apically truncate (as opposed to apically rounded, as seen here), and would have a more longitudinally wrinkled and uneven surface, at least in age. its consistency is more fragile-fleshy. i don’t know if any spp. occur on wood, but I only know them to be terrestrial.

it is also worth mentioning that Xylaria is most abundant and diverse in the tropics and subtropics, while Clavariadelphus is, at least predominantly, if not exclusively, temperate.

why not?
not arguing; just wondering why.
i am still trying to learn about Clavariaceae.

is it the hollow fruit body or substrate or both?
