Suillus brevipes

Suillus brevipes is a species of mushroom belonging to the genus Suillus, which is part of the family Suillaceae. This mushroom is commonly known as the short-stemmed slippery Jack or the stubby-stalk. It is a mycorrhizal fungus, forming symbiotic associations with the roots of pine trees, which is a characteristic trait of the Suillus genus. Suillus brevipes is found in various parts of North America, particularly in coniferous forests where its host trees reside.

Description

Suillus brevipes features a cap that can range from 5 to 10 cm in diameter, initially convex before flattening out with age. The cap's surface is smooth and often slimy, with a color palette that varies from yellow-brown to reddish-brown. The mushroom's stem is short and stout, typically 2 to 5 cm in length, which contributes to its common name. Unlike many other Suillus species, Suillus brevipes does not have a ring on its stem. The spore print of this mushroom is brown, and its spores are oval and smooth.

Habitat and Distribution

Suillus brevipes predominantly forms mycorrhizal relationships with pine trees, including species such as Pinus ponderosa (ponderosa pine) and Pinus contorta (lodgepole pine). These relationships are crucial for the nutrient exchange between the fungus and the tree, benefiting both organisms. The mushroom is commonly found in the coniferous forests of North America, from the Pacific Northwest down to the southwestern United States and into Mexico. It prefers moist, well-drained soils and is typically found growing in groups.

Edibility

The edibility of Suillus brevipes is considered good, although it is not as highly regarded as some other members of the Suillus genus. The slimy cap skin can be removed before cooking, as it is often unpalatable. The mushroom is best consumed when young and firm, as older specimens can become slimy and less appealing. It can be used in a variety of dishes, including soups, stews, and as a sautéed side dish.

Conservation

Currently, there are no significant conservation concerns for Suillus brevipes, as it is relatively widespread and common in its natural habitat. However, like all wild mushrooms, it should be harvested sustainably to ensure that populations remain healthy and viable for future generations.
