Observation 53250: Fulvifomes robiniae (Murrill) Murrill
When: 2010-09-19
No herbarium specimen

Notes: A hoof-shaped, woody, medium size shelf found on the bark of a dead black locust tree. The top had concentric color zones and ridges. The predoninant color was dark red-brown. The chocolate-brown under side had minute pores, relatively thick walled. They were not visible to my naked eye but were easily seen with 5X magnification. Some specimens have several annual layers of tubes (Photo 4).

Probably Phellinus rimosus rather than P. gilvus.

I originally labeled this Phellinus gilvus, but I think it is more likely Phellinus rimosus. It was found on a black locust tree and the color is better for P. rimosus. I understand that some think P. rimosus and P robiniae are synonyms.

I found this on Cape Cod

Hi, I found this this summer on Cape Cod in Nickerson State Forest and saw that it was also on dead black locust (Robinia psuedoaccacia). I first ID’d my specimen with Bessette’s Cape Cod book as P. robineae and saw P. rimosus in Lincoff. I think they are synonymous.
