Removed the carpet to install vinyl floor and discovered this. Is this mold? Fungus? What should I do? Should I remove the subfloor and see underneath?
Did the carpet has that speckled foam stuff under it?

Do you live in a humid area? Mold and fungus are the same thing and that’s what it looks like to me given the discoloration that looks like water damage.

At first I thought it was mold, but if it’s dry and crumbly, it’s probably disintegrated foam bits from the carpet padding. You should be able to vacuum it up.

Dye/ residual foam from the carpet padding/underlayment. Nothing to worry about.

Eh no harm in spraying it with bleach.
