Fresh Mushrooms

Fresh Mushrooms

How long are mushrooms good for? I bought some fresh mushrooms and used them for kabobs a little over a week ago. I still have some left that I would love to put in spaghetti sauce, but I have no idea how to tell if they are still good or not? Any tips on how to determine if they are still fresh enough to use? Any guidelines on how long mushrooms keep? Thanks!
