Boletus regineus makes sense

as a californian “aereus”, providing it doesn’t grow with hardwoods like Fagus or Quercus. If it does, I can still imagine the true Boletus aereus even in California.

this is not “piniphilus”/rex-veris, which grows under pine in the Sierra in the spring.
California “aereus” is now being called Boletus regineus sp. nov.
