Yes, fresh mushrooms can be frozen. This will however be frozen in a particular manor for them not to go bad. Start by washing the mushrooms, trim of the ends and then cook them. Heat the mushrooms in a frying pan with a small amount of butter or oil over high heat and then steam them. Finally allow the mushrooms to cool completely. Then, pack them in freezer safe packages, leaving 1/2 inch of headspace for expansion. The frozen mushrooms should be used within a year or before not letting them get spoiled.

If you are talking about white caps or Portobello mushrooms then yes they can be frozen, however some edible wild mushrooms become toxic when frozen, so if they are wild mushrooms please double check a mushroom identification guide for notes on toxicity.
