Don’t go by any general rules. If you are unsure, take it home and sit down with your mushroom guide book and go through all the ways of identifying it and separating it from similar species until you are sure, or you give up and throw it away.
Just off the cuff here are a couple of examples that violate the advice given above, golden chanterelle is very spicy but perfectly edible; gyromitra esculenta (“false morel”) does not have lamelles, is supposed to be mildly flavoured, but is deadly toxic.
