It was fruiting near the base.

The close-ups are from a sporocarp about 4.5 feet up. And the upper observation is from about 15 feet up the snag.

Snag, a standing dead log. Probably dead for as long as it was living, about 20-25 years. Stand really too crowded, and I suspect many of the affected stems were killed while still trying to stay alive, but too many crown trees nearby. One massive Western hemlock is over 6 feet diameter at breast height, and easily 200 feet or more tall, just by eyeballing it. Lots of downed logs and standing snags, as well as branches. A clear-cut area, fortunately not very wide or long, is about 50 feet away from this obs. On north side of road additional old-growth Western hemlock and scattered Douglas-fir make this one of my favorite close-by collecting sites. Such diversity!!

Heterobasidion is a root rot pathogen and fruits near the soil line. Pores start out white but change to a pinkish beige.
