Bracket Fungus

Cracked Cap Polyphore is so intimately associated with black locust (Robinia pseudoacacia) that the fungus’s binomial memorializes it: Phellinus robiniae. Hard to find the tree without the fungus. Right next to this black locust is another, and it also sprouts some of these shelf-like fungal growths.

N.B.: both of these locusts are still alive.
