Pores soon free of stem; bright yellow, unchanging. Stem 60-120 x 10-45mm, bulbous to equal; bright golden yellow; surface finely reticulate on upper half. Flesh firm; yellow. Odor pleasant.

Comment The cap of this species changes color markedly from young to old and is strongly reminiscent of Xanthoconium (=Boletus) affine (Pk.) Singer, with which it might be better grouped. |
