Natural spalting is best, no way around it.

But years ago when I was doing a lot of wood turning a lot of us were "force" spalting by rough turning a bowl, Christmas ornament, or just about anything else, and we put the objects into a tightly sealed trash bag covered with all the green shavings.

In a way, forced spalting is natural. Uses the same process, fungi and/or mold. The difference is one placing the ingredients in place, rather than it naturally occurring.

Another example: Holiday pumpkins, left on a table top too long, often mold and discolor the table. Obviously, other produce will do the same.

I usually hose off the saw dust and dirt from freshly milled lumber. If it's not washed thoroughly, any remaining debris might mold, causing discoloration, even if it's stickered. The last pine I milled discolored this way.

One of the reasons lumber mills continuously spray water on their cache of logs is to help prevent spalting.
