Anyone know what this is black dusty stuff is?

I was out on my deck today and found this stuff growing on the siding under my French doors that exit to my deck. If you touch it puts out a cloud of black dust. I'm assuming that it is some type of fungus but I'm hoping it's not from rotting wood. Any help would be much appreciated.

Could be a species of Stemonitis, a fungus or slime mold. (Stemonitis Splendens?) Scrape it off, wash it off, end of problem. Might come back... if it does, repeat. What it is is kind of beside the point unless you just want to satisfy your curiosity.

If you leave it there, yeah it can rot the wood, cuz it is feeding off it.

Usually a fresh coat of paint after cleaning it will prevent or at least slow down a reoccurrence.
