Suillus brevipes

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 does not have either a partial veil or prominent dark or 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.
