Recognized by sight: A very interesting collection, I hope you saved it.
It resembles Boletus flavissimus, except for the fact that Murrill does not mention the red cap in young specimens; which could mean he didn’t see one, or this is something different. What gets called B. pseudosulphureus in the south is probably the same?

Recognized by sight: We are in the process of publishing this species. As shown, this specimen does not fit the description of either B. flavissimus due to the degree of reddish coloration of cap when young and maintained into maturity. Also, according to Murrill B. flavissimus lacks reticulation. N. pseudosulphureus also lacks red coloration on the caps and has a non-reticulate stipe. We frequently collect these specimens.
Used references: Boletes of Eastern North America by Bessette, Roody & Bessette
