Used references: Arora, Mushrooms Demystified, p. 529. Young pores more white than normal. Said to favor spruce, which appears to be present in the background of the photos. Not known from Oregon that I’m aware of.

Indeed there is a “spruce” form of Boletus edulis.

It’s shown and discussed in Arora. It is found in the Rockey Mountain states, probably with Engelmann spruce.

The Sitka spruce variety on the Oregon and Washington (and probably California) coast varies from this in having a lighter cap (the spruce B. edulis has a red cap); mycorrhizal association with Sitka spruce instead of Engelmann spruce; and mostly white pores (B. edulis pores are yellowish but turn olive yellow in age).

I suggest this is one of the millions of unnamed species currently lumped together for the ease of book publishers. In the future we will learn it is different than Boletus edulis.

The lumpers will still lump it with Boletus edulis and eat it. But like an 80% of other fungi found in PNW, it is actually unnamed at this time.

is 8 miles S of Newport, this site would actually be closer to Waldport, wouldn’t it?

Most of the trees in that area are either Lodgepole pine (not shown in the photos) or Sitka spruce (twigs shown in the photo).

Are you asking for specific location?

It was found 12 miles south of newport Or, 1 mile inland.

It was in the woods along the edge of a tree farm. Not sure what type of trees I think it was mostly conifers.

It was about 20 cm tall growing at the base of a tree.

Can you be more specific than Newport?

This looks very similar to Boletus barrowsii, which prefers dryer habitats than the Oregon coast. We’ve had several similar collections at OMS, but no one seems willing to suggest a proper scientific name, even after microscopic examination. Usually it’s lumped in with Boletus edulis (which it is not).
