Extract from Wikipedia article: Suillus brevipes is a species of fungus in the family Suillaceae. First described by American mycologists in the late 19th century, it is commonly known as the stubby-stalk or the short-stemmed slippery Jack. The fruit bodies (mushrooms) produced by the fungus are characterized by a chocolate to reddish-brown cap covered with a sticky layer of slime, and a short whitish stipe that has neither a partial veil nor prominent, colored glandular dots. The cap can reach a diameter of about 10 cm (3.9 in), while the stipe is up to 6 cm (2.4 in) long and 2 cm (0.8 in) thick. Like other bolete mushrooms, S. brevipes produces spores in a vertically arranged layer of spongy tubes with openings that form a layer of small yellowish pores on the underside of the cap.
Suillus brevipes is a species of bolete fungus characterized by its short to medium stature, typically 3-8 cm tall and 3-6 cm wide, with a brown to reddish-brown cap and white to yellowish pores. In East and Central Texas, it is commonly found in association with loblolly pine, particularly in sandy soils and woodland edges, from summer to fall. The fungus produces a mild to sweet odor and has a soft, edible flesh, although its flavor is often described as bland. It can be distinguished from similar species by its short stem and lack of prominent reticulation.

The fungus was found growing on terraces over creeks, near creek crossings, and along hiking trails, often in association with pine trees. Multiple observations were made in the Sam Houston National Forest, particularly on the Lone Star Hiking Trail and North Wilderness Trail, where the mushrooms were found growing in large numbers. The fungi were also observed on mowed roadsides, including Road 149, where they were found in abundance. Dissections of the mushrooms revealed their internal structure, including gills and caps. Observations were made over several years, from 2013 to 2021, during the fall and winter months, suggesting that Suillus brevipes is a common and widespread species in East and Central Texas.
