Butterdish yellow-brown

Cap: In a yellow-brown oiler, the cap is initially semicircular with a tucked edge, later cushion-shaped, 50-140 mm in diameter. The surface is initially olive or gray-orange, pubescent, which gradually cracks into small scales that disappear in maturity. In young mushrooms, it is gray-yellow, gray-orange, later brown-reddish, light ocher at maturity, sometimes slightly slimy. The peel is very difficult to separate from the pulp of the cap. The tubules are 8-12 mm in height, at first adherent to the stem, later slightly cut, at first yellow or light orange, dark olive at maturity, slightly blue at the cut. The pores are small at first, then larger, gray-yellow, then light orange and finally brown-olive, when pressed slightly turn blue.

Leg: The leg of a yellow-brown oiler is cylindrical or clavate, 30-90 mm high and 20-35 mm thick, smooth, lemon-yellow or lighter in color, in the lower part it is orange-brown or reddish.

Flesh: Firm, light yellow, light orange, lemon-yellow above the tubules and under the surface of the stem, brownish at the base of the stem, slightly blue in places on the cut. Without much taste; with the smell of pine needles.

Spore powder: Olive brown.

Spores: 8-11x 3-4 microns, ellipsoid-fusiform. smooth, light yellow.
