I found this Polypore on a big black walnut today. It was ID’d as being Bondarzewia berkeleyi on one of the Facebook ID groups. It seems to be indicative of butt rot in hardwoods. Was curious if anyone found there was an indicator as to how severe that it may be; my intuition says it is *probably* fine. The canopy looked good but I know that doesn’t always correlate with what’s happening inside or below the soil line.
