Umbrella polypore

Polyporus umbellatus

A species of Polyporus.

The umbrella polypore (Polyporus umbellatus) creates a dense cluster of caps that strikingly resembles an enormous hydrangea blossom. This formation typically emerges at the base of a tree suffering from white-rot, caused by the fungus. As long as the host tree survives, this parasitic fungus tends to reappear in the same location during summer or autumn over multiple years.
