This is almost certainly Crytoporus volvatus: unfortunate for the host tree, as this fungus has an open chamber on the bottom where Ambrosia bark beetles can overwinter, then spread their eggs and infect more trees. The beetles can easily girdle trees, killing them. Next time you find one (they will be on the same tree and likely nearby trees as well), slice one open from the top to the bottom. There should be a tiny hole near the bottom which leads into a spore-producing chamber with descending hymenium. This drops the spores on the beetle, and spreads the infection with the beetle eggs.
