If scanning the environment while walking or jogging works, then I'd recommend learning how to identify edible mushrooms. Whenever you're outside you go into 24/7 extreme scanning mode that is pretty much impossible to turn off.

Beginning mushroom hunters find mushrooms by seeing them. Expert mushroom hunters just see things in their peripheral vision that are consistent with a mushroom being there. (E.g. some leaves out of place, a pop of color where there shouldn't be, a wisp of smoke, etc.) By the time you actually consciously focus your eyes/attention on the area and get close enough to see whether or not there really is a mushroom, you're already pretty sure whether or not you've found something.

Why a wisp of smoke? Because they see something grey or are mushrooms out there starting forest fires?

If the mushrooms are older you can sometimes see the spores before seeing the actual mushroom. This obviously happens with puffballs, but I've also seen it with Honey Mushrooms and Maitake.

These are really bad for you to breathe in though, so if you see this happening then definitely go in the other direction.

Visible evaporate == really good mushroom habitat, most of the time.
