Scientific names: Phellinus everhartii (Ellis &
Phellinus igniarius (L.) Quel.;
(Brot.) Bondartsev & Singer
Derivation of names: Phellinus means "made of cork"or
"corky." Everhartii honors B.M. Everhart, a mycologist who
lived from 1818 to 1904. Igniarius refers to "fire." Pini
indicates its occurrence on pines (Pinus spp.)
Synonymy: Index Fungorum lists the current name of P. pini
as Porodaedalea pini (Brot.) Murrill
Comments: A number of Phellinus species occur in the
Northeast. These perennial species are resupinate, effused-
reflexed, or sessile. Cap colors vary from yellowish to
to gray to black. Caps may be cracked or not.
The pore surface
is brownish. They have a brownish context
microscopic setae. Many are parasites. Some
occur at the base
of the tree
(root and butt rot species) and
others are high up on the tree (trunk rot species). Most
use of a
microscope to identify them with
certainty and are
included in the keys. A few
species are pictured

many genera and continues as a saprotroph after the tree
dies. According to Gilbertson and Ryvarden, P.
is a complex of closely related species. Photo © Tom Volk.
