The mushrooms you're looking for are pretty small, and hidden underneath and behind the larger mushrooms scattered around the cave.

It would appear that you can only do one cooking daily per day, regardless of city. I'd done the one in Orgrimmar and alas, there is now no cooking quest to be found in Thunder Bluff. Sad day.
The yellow description when you mouseover the mushrooms in your bags reads:
"Delicious and completely absent of psychedelic proprieties"
Love how this is ok but not the wolpentiger or pink ellek quests on EU servers.

Description
You know of the Pools of Vision, yes? There is a sort of mushroom that grows there... not the tough, rank fungi that dominates the place, but smaller, more delicate caps that grow beneath them. They are rare and quite delicious, adding a flavor to meat dishes that one might even call magical. ...what? No, really. They just taste good. That's it.
