Phellinus robiniae is the name to use for this taxon on locust trees. Phellinus rimosus is a similar Old World species (Europe, Africa, Asia).

Great call Martin…

I looked at the uncropped image and it was indeed a black locust tree. Some of the other images on MO have more of a creamy pore surface like this one.

They are very conspicuous this time of the year; they only grown on black locust. I can’t tell if yours in growing on black locust or not. As you will see, all of mine have a brown pore surface, so it may not apply to what you photographed.
