Tylopilus rhodoconius is a species of bolete fungus that grows in association with trees, particularly oak and pine. In East and Central Texas, it typically fruits from June to October, often in sandy soils and wooded areas. The cap is pinkish-red to reddish-brown, 3-8 cm wide, and convex to flat. The pores are small, angular, and yellowish to olive-green. The stalk is similar in color to the cap, 3-6 cm long, and 0.5-1.5 cm thick. Spores are brown in deposit and elliptical in shape. This fungus is considered edible, but its quality is often reported as poor due to a soft, bitter, or unpleasant texture.
