Polyporus brumalis also has more or less radially elongated, diamond-shaped pores, but they are much smaller than those of N. alveolaris, the cap is darker, the stem more central, and the spores smaller, (Gilbertson).Habitat
annual, on dead hardwood, associated with a white rot, (Gilbertson), on dead hardwood (Phillips), summer and fall (Miller)
