i'm probably just seeing stuff thats not there... but i wouldnt ID it as mahogany just because of the colour.. i dont think its oak or beech either i just mentioned them as woods with lots of medullary flecking, which is what i think i can see when i look at that picture but dont mind being wrong.
if the dark bits are actually pores rather than flecks its most likely mahogany or some far eastern variant of it.
