These are common on the west coast and go by two names Porphyrellus porphyrosporus or Tylopilus porphyrosporus. As far as I know, the variety is Tylopilus porphyrosporus var. porphyrosporus. According to Wolfe, Tylopilus porphyrosporus var. olivaceobrunneus should have a reticulated net on the stipe covering half to one third of it and has been found in Oregon.

I have to ask what made you come to the conclusion these were different from Tylopilus porphyrosporus? The cap color seems to be within the variability seen for the later. The Bessette book says that the olivaceobrunneus variety fruits under Doug fir. Staining reactions?

If you see it again at Pt Reyes – please save a specimen
