Used references: According to Dimitar, this was finally published in late 2008 as a separate species in the journal of Economic Botany in the article “California Porcini: Three New Taxa, Observations on Their Harvest, and the Tragedy of No Commons” by Arora and Simonini. I’ll provide more details as I get them.

Recognized by sight: now that I’m looking at these a litle harder…why wouldn’t this mushroom, from a known barrowsii location, not also be that pale bolete species?

Don’t think it’s B. barrowsii

It had some brown tones and was under heavy pine needles. The particular area is where I’ve found a number of B. edulis var. grandedulis in the past. Also in coastal California I’ve only seen what I would call B. barrowsii under live oak. I’d actually be really interested to see some ITS sequence data from our white live oak porcini and compare it to the other porcini of the western US.
