Observation 161132: Phellinus everhartii (Ellis & Galloway) A. Ames
When: 2014-03-09
No herbarium specimen

Notes: Growing at the base of dead standing oak. The impaled debris shows that these FB’s were scoured by flood waters caused by the heavy rains on 3/1 and 3/2 which may have affected colors. We found Trametes and Fomitopsis species similarly affected by this storm.

on the cap is definitely black. Also, according to Kuo Pseudoinonotus dryadeus is parasitic on living oaks in the east (the oak in this obs is dead and not recently so) and on true firs in the west—see Kuo, M. (2010, March).

Ime, the pores darken and the pileate portion becomes aerolate as I. dryadeus ages. If the pileate portion is truly black then this proposal seems less likely.

Thanks for the proposal Rocky

We’ve found Pseudoinonotus dryadeus on living oak and it is quite different—spongy to the touch, bleeds red, lacks the cracked black cap surface and has a mild odor—also pore color is different.
