Discolored wood

[stf01]

Hello

What type of discoloration is this? The wood is kind of discolored, 50 years old, but then there are some light "spots"...


It's under the pillar foundation, a little everywhere. I've felt it with a knife, it's hard. You can see the same thing two beams behind as well. There's no difference in contour on these spots.

It is probably wasps, bees, or bumblebees that have gnawed off the outer wood and exposed fresh wood.
