Boletus coniferarum, the conifer bolete, is a mushroom of the genus Boletus native to North America. The species is inedible[1] due to its extremely bitter taste.[2]
The semi-velvety cap is grayish and the yellow tubes stain dark blue.[2] The stipe is yellowish, darkening in age, and sometimes larger near the base.[2] The flesh is buff and stains blue.[2]
Boletus frustosus is similar, but has reddish hues at the bottom of the stipe,[2] as does Cyanoboletus pulverulentus, which stains a greener hue than B. coniferarum and tastes mild.[2]
