Suillus hirtellus is a species of bolete fungus that grows in association with loblolly and shortleaf pine trees. In East and Central Texas, it typically fruits from May to October, producing medium-sized, brown to tan caps with yellow to brown pores and a stout, hairy stem. The fungus is commonly found in sandy soils and wooded areas, often in abundance under mature pines. Its distribution in the region is widespread, with records from many counties, including Travis, Williamson, Bastrop, and Houston.
