The PHAK already answers my question, by the way. Chapter 12 page 12-15 states "Fog is a cloud that is on the surface."
So yesterday's little fog phenomenon on the runway (and nowhere else) means that even in Class G airspace, you cannot takeoff in something as benign as this since you wouldn't be "clear of clouds."
It was gone by the time I started the engine.
