Boletus miniato-olivaceus

[2] The species was first described by American botanist Charles Christopher Frost in 1874, from collections made near Marlboro, Vermont.

The color in young specimens is red, changing gradually to pale rose-pink or rose-tan with greenish or yellowish tints in maturity.

The pore surface on the underside of the cap is initially yellow but turns dingy olive-green (sometimes with reddish tints) when older.

They can be used in mushroom dyeing, and produce colors ranging from brown, beige, yellow, or light orange, depending on the mordant used.

Its distribution includes eastern Canada south to Florida, extending west to the Great Lakes region.
