This beautiful, late season mushroom can be seen lining sticks and tree trunks. It appears to be a toothed fungus, but is actually a polypore. Sometimes the caps are not well developed and it grows flat against the branch. Milk White Toothed Polypore (Irpex lacteus). Photo contributed by Lisette Lauzon.
