Observation 146705: Hydnum rufescens Pers.

These were growing in primarily a Sitka spruce habitat.
Caps up to 5 inches across.
Spore print was white.
Spores were ~ 6.0-8.0 X 6.0-7.1 microns, globose to subglobose.
A few seemed smooth but many had a soccer ball-like or plated appearance.
Steve Trudell notes this species in his book but I don’t see much else about their presence in the PNW.
5-5-2017; According to Rachel Swenie at the U. of Tenn., who sequenced this collection, these are unlikely the H. rufescens of Europe. They seem to belong to a clade of western NA Hydnum and probably a new species. She will be during more work to determine species boundaries.
