Butyriboletus floridanus is a species of bolete fungus that grows in association with oak trees. In East and Central Texas, it typically fruits from May to October, producing medium-sized caps that range from yellow-brown to reddish-brown in color, often with a velvety or wrinkled surface. The pores are yellow and stain blue when injured. It is found in wooded areas, particularly under live oak and post oak, where the soil is rich and moist. The fungus is considered edible, but caution is advised due to potential confusion with lookalike species.
