The profuse whitish latex may become brownish upon exposure to air, and stains tissues brown.
The fruit body of Lactarius volemus has a fleshy and firm cap with a velvety or smooth surface and a shape that changes with maturity: it starts off convex, with edges curved inwards, then later grows flat with a depression in the middle. With a typical diameter of 5 to 11 cm (2–4 1⁄2 in), its colour ranges from apricot to tawny. The cap colouration, however, is somewhat variable, as has been noted in Asian, European, and North American specimens. The stem, whose height varies between 4 and 12 cm (1 1⁄2 and 5 in), and which is typically between 1 and 1.5 cm (0.4 and 0.6 in) thick, has a slightly lighter colouration than the cap
