Having trouble finding the basidia, I found spores still attached to the basidia but couldn’t make out any detail about the basidia. Spores have turned out actually to be ellipsoid rather than globose. I think Dacryopinax spathularia might be a possibility because you can make out a spatula shape on a couple of the fruitbodies, also its preference for growing on structural wood, and spore characters are consistent.
