AI-generated summary of observations

Retiboletus ornatipes was observed under oaks, pines, Yaupon, and magnolia in the Big Creek Scenic Area of Sam Houston National Forest, typically on higher ground. The bright yellow bolete mushrooms had long stems and yellow pores on their underside. Cross sections revealed a consistent internal structure. Some specimens showed yellowing sections, while others appeared fresh and vibrant. The mushrooms were found to have a distinctive appearance, with yellow pores and a bright yellow cap. Observations were made in July 2021, suggesting that this species may fruit during the summer months in East and Central Texas. The variety of tree species under which they grew suggests that Retiboletus ornatipes may have a wide range of potential host trees.
