Suillus subluteus, commonly known as the slippery jack or subalpine fir suillus, is a species of edible mushroom in the genus Suillus within the family Suillaceae. It is found in coniferous forests across North America and Europe, forming symbiotic relationships with the roots of pine trees. The mushroom is characterized by its slimy cap, which can vary in color from yellow to brown, and the presence of a ring or annulus on its stalk.

Description

Suillus subluteus mushrooms have caps that can range from 5 to 10 cm in diameter, initially convex before flattening out with age. The cap surface is sticky or slimy, especially when wet, and is yellow-brown to olive-brown in color. The underside of the cap features spore-bearing tubes instead of gills, which are a distinctive feature of the Suillus genus. These tubes are yellow and become olive-yellow as the mushroom ages. The stalk measures 4 to 10 cm in height and 1 to 2 cm in thickness, often featuring a distinctive ring that remains from the partial veil that once enclosed the developing spores.

Habitat and Distribution

Suillus subluteus is predominantly found in coniferous forests, particularly in association with pine trees, with which it forms ectomycorrhizal relationships. This symbiotic relationship is crucial for the nutrient exchange between the soil and the tree, benefiting both organisms. The species is widely distributed in North America and Europe, thriving in both lowland and mountainous regions.

Edibility

The mushroom is considered edible, although not highly regarded due to its slimy texture, which some find unappealing. It is recommended to remove the slimy cap skin before cooking. Suillus subluteus can be used in a variety of dishes, including soups, stews, and as a sautéed side dish. However, individuals should always exercise caution and ensure proper identification before consuming wild mushrooms, as there are many look-alikes that could be poisonous.

Conservation

While Suillus subluteus is not currently listed as endangered or threatened, its existence is closely tied to the health of coniferous forests. Deforestation, climate change, and pollution pose indirect threats to its habitat and, consequently, its population.
