Lactarius subpalustris is a species of mushroom that grows in association with pine trees. In East and Central Texas, it typically fruits from May to October, often in sandy soils under loblolly or shortleaf pines. The cap is 2-6 cm wide, convex to flat, and reddish-brown to orange-brown with lighter patches. The gills are pale yellowish to cream-colored and exude a white to pale yellow latex when injured. The stem is 2-5 cm long and 0.5-1.5 cm thick, often tapering towards the base.
