Fistulinella jamaicensis is a species of bolete fungus that grows in association with roots of certain tree species. In East and Central Texas, it has been found to fruit in late summer to early fall, typically under oak, pine, and other hardwood trees. The cap is 3-8 cm in diameter, reddish-brown to brown, and often cracked or wrinkled, while the pores are yellow to greenish-yellow and stain blue when bruised. It is considered a rare species in the region, with limited collections reported from areas such as the Lost Maples State Natural Area and the Sam Houston National Forest.
Observations of the fungus Fistulinella jamaicensis in East and Central Texas reveal its presence under various tree species, including oak, pine, magnolia, and holly. The mushroom was found on Kirby Trail in Big Thicket National Preserve, Warren, Texas, on September 25, 2021. It was observed growing alongside the white corticioid fungus Dendrothele candida on a piece of tree bark. The bolete mushroom's cap, underside, and side view were documented, showing its distinctive features. A cross-section and dissection of the mushroom were also made, providing further insight into its internal structure. These observations suggest that Fistulinella jamaicensis is able to thrive in the specific ecological conditions found in Big Thicket National Preserve, associated with a variety of tree species. The documentation of this fungus provides valuable information about its habitat and morphology.
