Lactarius fumosus

The cap surface is dry, unpolished, azonate, usually becoming somewhat wrinkled with age, pale dingy yellow-brown to whitish overall, with a smoky tinge, sometimes with tawny olive, pinkish buff, or dull brown areas.

The gills are attached to subdecurrent (running slightly down the length of the stem), narrow, crowded together, whitish, becoming dingy yellow-buff, staining reddish when bruised.

The stem is 4–11 cm (1.6–4.3 in) long, 6–15 mm (0.24–0.59 in) thick, nearly equal, dry, dull, stuffed, colored like the cap, whitish towards the base, staining reddish, but more slowly than the gills.
