Acro ID?

So @madweazl generously gave me a piece of a colony.

Frag that fell off (after like a month of growth):

Full Colony:

At first I thought it was Red Planet/A hyacinthus, but it looks less and less so the more I look at it. (I would say "we" since I think @madweazl has come to similar conclusions, but I don't want to speak for him. :D )

Any guesses as to the scientific name (preferred) or trade name? Going through COTW, my guess is A. bifurcata, though cytherea (itself a species complex) and plana are also fairly similar.
