Gyroporus ballouii is a species of bolete fungus that grows in association with oak trees. In East and Central Texas, it typically fruits from June to October, producing medium-sized, brown to reddish-brown caps with yellow pores and stems. The flesh is white and has a sweet, nutty odor. It can be found in woodland areas, particularly under live oak and post oak, where it grows singly or in small groups. The fungus is edible and considered a delicacy by some mushroom enthusiasts.
