Figure 300.—Boletus auripes. One-half natural size. Caps yellowish-brown. Tube surface and stem yellow.

Auripes is from aureus, yellow or golden; pes, foot; so called from its yellow stem.

The pileus is three to four inches broad, convex, nearly smooth, yellowish-brown, the flesh often cracking in areas in old plants; flesh yellow at first, fading to a lighter color, in age.

The tubes are nearly plane, their mouths small, nearly round, at first stuffed, yellow.

The stem is two to four inches long, nearly equal, often reticulated, solid, a bright yellow on the surface and a light yellow within. The spores are ochraceous-brown, tinged with green, 12×5µ.

The whole plant, except the upper surface of the cap, is a golden yellow, and even the surface of the cap is more or less yellow. It favors one form of the B. edulis. It is sometimes found in mixed woods, especially if there are mountain laurels in the woods (Kalmia latifolia). It is found in July and August.
