That much we can be sure of. :) In all seriousness, we can narrow it down to a small handful of species. But since you’re so far out of my geographic range, I hate to go on record saying anything with certainty.

Bug Alan, I think he still has it. :)

Also, what genus does “U.” refer to?

Looks a lot like U. parvula / U. cirrosa

It’s a tough genus, though. Things you’d need: color of medulla and central axis (sort of a rubber band-like consistency); K, C, KC tests on medulla; presence of papillae (“goosebumps”) on the surface of the main branches; texture of the medulla (U. parvula, for example, has a dense outer medulla and loose cottony inner layer). Probably one or two other things depending on the answers to these questions, but that’d be a good start. Dissecting microscope is highly recommended. (As is patience! :)
