Observation 117295: Suillus caerulescens A.H. Sm. & Thiers
When: 2012-11-19
No herbarium specimen

Notes: In grass, within 10 feet of Douglas fir. Cap viscid. Pore surface bruises brown. Pores slightly larger than 1 mm radially, slight narrower circumferentially. Lower part of stem stains blue-green (not deep) when cut. Upper part of stem does not bruise when handled. Photos taken on a very wet day, so cap color may not be typical. Taste not distinct, perhaps a trifle bitter.
Is this Suillus caerulescens or Suillus lakei?

I don’t know what I was thinking

This is definitely not S. pungens. I’d say that it’s S. caerulescens because the veil is dry and it occurs with Doug fir.

From my limited knowledge, I don’t think this is S. pungens. That species does not appear in Pacific Northwest-specific guidebooks or keys. See Scates, Gibson & Bishop, Trial field key to the BOLETES in the Pacific Northwest (rev. 2011); Trudell & Ammirati, Mushrooms of the Pacific Northwest (2009).
And according to Arora, Mushrooms Demystified (2d ed. 1986), S. pungens is associated with Monterey pines. And Arora does not mention stem staining for S. pungens.
But this is a residential area with some non-native trees, and there are some Shore (2-needle) Pines about 50 feet away on the other side of an asphalt driveway.
