Suillus fuscotomentosus, commonly known as the poor man's slippery jack,[1] is an edible species of mushroom in the genus Suillus. Found in western North America, it was described as new to science in 1964 by mycologists Harry Delbert Thiers and Alexander H. Smith. It usually grows under three-needle pines, such as ponderosa pine and Monterey pine. Although it is edible, it is often considered to be of poor quality. David Arora once said that, according to many people who tried this mushroom, it ranks at the bottom when compared to other boletes.
