From Facebook Group, All Things Polypore (I'm reposting here for a more permanent collection) ME: This lovely polypore is on a fallen oak in Athens, Georgia USA. There were three clusters growing near each other (see photo): younger-more white; intermediate; older-more brown. All three groups have a browish rim and up close are velvety on top. Pores 3 per mm. Cap 1 cm thick.
