Oak Conk

Phellinus gilvus

Description:

Decaying polypore growing out of a stump about 1.5 - 2 feet in diameter. Largest cluster was about 9 inches across. Last picture is of cluster that was growing on the roots several feet away.

Habitat:

Found just outside of Comstock Riverside Park, which is full of hardwoods, conifers, and beeches. The park floods from time to time and can often be very marshy.

Notes:

Appears parasitic. I found this specimen in front of someone's house (not in their front lawn, but the lawn in front of the sidewalk in front of their house). While I was examining it, a woman who lived there was leaving and she told me that it had killed the tree the spring before. I also observed that both of the trees on either side of stump, despite being separated by driveways and well over a dozen feet, also appeared to be dying. They appear to be the same species of tree (will confirm when the leaves come in) and I highly suspect that they are infected with the same fungi.
