I see evidence of at least three fungi there. The center was originally attacked by the brown cubical rot, but when it died, the red crumbly rot took over. What likely actually killed the tree was the laminated root rot, which is evident in the remaining sapwood and the stain in the log on the mill. Note that the brown cubical rot seldom kills trees except by accident, the red crumbly rot is a decay fungus that only sets in after the tree is dead, and the laminated root rot can kill a healthy tree in a matter of weeks. Autopsying trees from the stumps and logs is essential in understanding the dynamics between trees and their associates beneath the soil; a healthy tree may show no evidence of disease hidden deep within the bole, while a dying tree may show symptoms of something other than what's killing it. The post-mortem is where all the pieces come together into a clear picture.

How can I tell the difference between brown cubicle rot, (called heart rot in redwoods) and red crumbly rot?

Sometimes it's tough. They can look and feel almost the same. Usually brown cubical is inside and red crumbly outside, but that's not always the case. Conks help some; the former is on the ground and thin, the latter is on the stem and thick. But, a lot of the time you won't have a conk conveniently located. Lots of things can be confused with others. You just have to sort of calibrate your eye to see the stuff needed to tell one from another. It takes practice.
 
This one had a large buttress on the backside. I faced both trunks and back cut the front. Then I back cut the buttress and ran away bravely. It fell where I aimed it. Dern lucky.

Now, I ask a shocking question. How do you get shocked whilst sawing whilst standing in water? Is it worse wearing calks? I must know these things!

I stuck a waterlogged knee under the rear handle for leverage, the gravel shifted under my boots (non-caulked) my leg slid off the handle and went right where the spark plug lives. It was quite a pop, McCulloch magnetos crank out the volts at full revs. The water level was right at my knees.
 
Well......finally went back and dropped the tree.............had more good wood in it than I thought it would. Bored in and sure enough, good center wood. Used some rigging to pull it away from a nearby asset ( footbridge). Just kept it old school, and over she went......
