Observation 161777: Polyporaceae Fr. ex Corda
When: 2014-03-19
No herbarium specimen

Notes: Someone gave this to me to identify. It was said to be growing on an oak (Tan Oak?) log or stump near Windy Hollow Road in Point Arena.
Out in the open not under forest canopy. Appears to have “pores” but are very large. Each pore has one to two “teeth in the center”. Pore surface feels slightly waxy.
Could not get much of a spore print but appears to be white.
Has dark brown to black, off-center stipe. Cap is very large (two are shown in photo, one large and one small—-the stipes are connected). The large one is 7.5 inch by 10 inches.
Flesh is white.
cap color is buff to orangish which red-brown fibrils.
Cap margin is upturned.
