    Looks quite a bit like bacterial wetwood to me. Interesting, looks as though it may be radiating out along rays.

    Ive seen similiar radial discoloration from trunk injections but don't recall seeing them coalesce in the center like that.

    I've been here 26 years. The house is 30 yrs. Never been tapped.
    Initially, I also thought old branches .................. but there are too many, and too regular..
    They run out to the last few yrs of growth; and there were no branches there since I got here.
    Also, there are too many vertically, and regular, to be branches. Those cuts are every 18" apart !

    Try again ?

    I'm not an expert with this stuff, but could it be from frost cracks or some other introduction of fungi.
    I can't really see from the pictures what caused it, but isn't it compartmentalized decay?

    "Wood-decay fungi spread through wood as microscopic strands called hyphae, which begin as either germinating spores or bits of hyphae carried to the wound by insects. These strands of wood-decay fungi often secrete oxidizing enzymes that discolor wood and reduce its resistance to decay. "http://www.nrs.fs.fed.us/pubs/gtr/gtr_nrs97.pdf

    Very well could be discoloration and decay caused by fungi.
