I brought several nice specimens of what I called Boletus nobilis. They were all very much the same with pale or absent reticulations. Michael Kuo did some chemical tests and separated out some Boletus atkinsonii, a species that I am familiar with but not with the rugose pileus. KOH gave an amber brown reaction on B. nobilis and was negative on B. atkinsonii (which is supposed to go brown as per BB&R.) So my confidence level has been shaken.
your not having complete confidence in calling this obs “Boletus nobilis” is at least partly on account of the stipe lacking reticulations.
A member of our local mushroom club made a very similar collection a couple days ago. Large fleshy bolete, non staining, pores white at first, and stipes without reticulations. The person who made the collection IDed it as B. nobilis. Based on my own collections which I have IDed as B. nobilis, this looked good to me… except for there being no reticulations, even at the apexes.
