Another difficult genus

I’m ruling out the very common H. imshaugii because your specimen clearly has “lobules” (also called adventitious lobes by some) — short perpendicular side-lobes which are constricted a little at the base — and H. imshaugii becomes really gnarled and compact in the southern parts of its range. I think H. gracilis and H. heterophylla are more likely candidates. The differences between these latter two are: H. gracilis is smaller (big help!) and has white to pale brownish interior, contrasting with H. heterophylla with its dark brown to black interior surfaces. [Interior, in this genus, refers to the inner surface of the tube, as seen by tearing open one of the hollow lobes, not the lower exterior surface.]
