Boletus appendideliciosus would be a fitting name ;)

Andreas, it seems that the european version of this is different , and we need a new name for this Californian type. For now we continue to eat them and they taste good by any name!

don’t know

whether those are identical with our european Boletus appendiculatus. The cap colour looks quite different, with those rose to pinkish coloration. Looks more like B. speciosus, but not the european pseudoregius. May be it’s still something different from those three.
