Observation 34609: Polyporales sensu lato

When: 2010-03-07

Collection location: Beaver Co., Pennsylvania, USA [Click for map]

Who: Bob Zuberbuhler (Bob Z)

No specimen available

A medium size semicircular shelf mushroom found on a dead deciduous log. The upper surface is rough and yellowish brown with some concentric color zones. The underside feels velvety. No pores are visible to the naked eye but minute pores asre seen with magnification. The cut surface shows tube length of several millimeters and there are several annual layers. I’m calling this Phellinus gilvus, but would appreciate other opinions. I’m worried that the tubes are rather long.

P. gilvus could well be it. If you knew the species (oak or poplar, say?) someone might be able to rule one or two other species out.
