I spent some decades in coastal California, saw satanas many times, always sort of startling. So here's one of the subject boletes, reddish reticulate stem, red cap, brick red pores that are yellow when I cut into them, the whole thing stains blue as fast as does B. bicolor when cut. The ones from out in the forest are clean but occur here and there, the ones from under the oaks in the parking lot islands at the county park are much rougher in surface, but that's where they come up in large groups. I'm used to touching boletes to my tongue to assess bitterness; these are citrusy, lemony.
The other thing shown is in the Falcon guide, which I still have, as Austroboletus. I found ONE of them a couple years ago when it was nearly as wet in summer as this year; now I have a dozen or so, they're pretty tasty but never more than one here and one there, not patches as with chanterelles or black trumpets.
Oh, and there are several yellow pored species here that have a lemony taste as well; one is bitter, I think there might be five or six closely related species. It was easy in California, with zelleri, edulis, and satanas, and a half dozen other reliably identifiable (for me) species out in the hills.
