Prepare butternut squash by peeling and seeding it and cut up and reserve 3/4 cup diced; the remainder place in boiling water and cook till tender. Drain and puree (should have 1 cup). Set aside. Mix remaining mushroom liquid with broth and chicken stock and bring to a simmer. Meanwhile saute the onions and garlic in the oil until soft but not brown. Add the 3/4 cup of diced squash, scallions and stir. Add the arborio rice to the pan and 2 ladles full of the broth.
