Well, as someone from Europe, there is a reason for the confusion, you are right, this isn’t actually a Boletus pinophilus. There is a Bolete that grows up in the Sierras in California, that got called B. pinophilus when first observed. Later people have found it was a new species, but it still hasn’t been published as a new species in all the years that this is known. The proposed name is Boletus “rexvernus”, but for a while now for a number of people we still just call it Boletus pinophilus, even though we know it isn’t. Sorry about that.
If there get to be postings here of the real Boletus pinophilus from Europe, we should split off of the Sierra observations to the new name, to keep them separate.
