One can not have too many recipes for risotto with mushrooms. It is hard to imagine any other foods that meld so perfectly. There are several risotto recipes available on www.classicpasta.com, but true to our calling, here is another.
This recipe comes from Janet Moga, of the East Bay, who has tested (and corrected) many of the recipes on the site. She uses slightly more dried porcini than we, but both are excellent -- your taste.
If you have truffle oil available, here is a great chance to use it.
