Spalted Maple question

My guess is that it was not properly kiln dried(not high enough temp).
Fungus is dead in kiln dried wood and dormant in air dried wood.

could you carve it into

a chia pet

it think bleach will stop the fungus
then see what you can do about the cupping

Fungal, mold, and mildew spores are all over the place. It does not matter that it was kiln dried because you un-kiln dried by leaving it in the rain. The spores were in the environment. The conditions were perfect for fungal/mold growth, and that is what happened.

Any wood that is kiln dried that is left out in the outside environment will re-equilibrate with the ambient environmental conditions, meaning that the wood will gain moisture, the amount based on the humidity. The board cupped because after it got wet, it dried more on the exposed side than on the underside, creating tension that caused the cupping. If you turn the cupped side down flat on a surface, it might flatten back out. Then, be sure and store it so that air can circulate freely around both side of the board until the board reaches equilibrium again.
