Hygrophorus roseobrunneus is a pinkish-brown to reddish-brown waxy cap fungus that grows in association with oak trees. In East and Central Texas, it typically fruits from September to November, often in clusters on the ground in wooded areas with rich soil. The cap is 2-6 cm in diameter, convex to flat, and sticky to moist. The gills are decurrent, waxy, and pale pinkish-brown. The stipe is cylindrical, equal, and concolorous with the cap. This species is considered rare to uncommon in the region.
