If dry now, I would call it water-stained from a past leak. If it is still wet, it's a leak. If there are fruiting bodies of mould that can be wiped with a finger, then I call it active mold growth.
But there are places you are advised to say mold-like or some other wishy washy term unless you have a PhD in moldology. :D

OSB takes 10 times longer than plywood to dry out. So that subfloor may need to be replaced if the moisture content is still over 20%.

For what it’s worth – I don’t see any mould.
