Common name: Pineapple Bolete.
Extract from Wikipedia article: Boletellus ananas, commonly known as the pineapple bolete, is a mushroom in the family Boletaceae, and the type species of the genus Boletellus. It is distributed in southeastern North America, northeastern South America, Asia, and New Zealand, where it grows scattered or in groups on the ground, often at the base of oak and pine trees. The fruit body is characterized by the reddish-pink (or pinkish-tan to yellowish if an older specimen) scales on the cap that are often found hanging from the edge. The pore surface on the underside of the cap is made of irregular or angular pores up to 2 mm wide that bruise a blue color. It is yellow when young but ages to a deep olive-brown color. Microscopically, B. ananas is distinguished by large spores with cross striae on the ridges and spirally encrusted hyphae in the marginal appendiculae and flesh of the stem. Previously known as Boletus ananas and Boletus coccinea (among other synonyms), the species was given its current name by William Alphonso Murrill in 1909. Two varieties of Boletellus ananas have been described. Although the mushroom may be considered edible, it is not recommended for consumption.

Boletellus ananas is a species of bolete fungus that grows in association with roots of trees, particularly oak and pine. In East and Central Texas, it typically fruits from May to October, producing small to medium-sized caps that are yellow to orange-yellow in color, often with a powdery or fuzzy appearance. The flesh is yellow and stains blue when injured. It can be found in wooded areas, especially under oak and pine trees, in regions such as the Piney Woods of East Texas and the Post Oak Savannah of Central Texas.
