http://en.wikipedia.org/wiki/SpaltingDark dotting, winding lines and thin streaks of red, brown and black are known as zone lines. This type of spalting does not occur due to any specific type of fungus, but is instead an interaction zone in which different fungi have erected barriers to protect their resources. The lines are often clumps of hard, dark mycellium, referred to as pseudosclerotial plate formation.
Zone lines themselves do not damage the wood. However, the fungi responsible for creating them often do.
ok, I will try to cut some of it this weekend if i can find a chain saw .what type of wax should i be using to protect the ends from cracking will parifin wax work i have a couple of lbs of that
