Suillus glandulosipes

Suillus glandulosipes Thiers & A.H. Sm 464166

Suillus glandulosipes is a species of mushroom belonging to the genus Suillus, which is part of the family Suillaceae. This species is closely associated with coniferous trees, particularly with pines, forming mycorrhizal relationships. These symbiotic associations are crucial for nutrient exchange between the soil and their host trees. Suillus glandulosipes is found in various parts of North America, where its preferred hosts, different species of pine trees, are native.

Description

Suillus glandulosipes mushrooms are characterized by their sticky, often slimy caps, which can vary in color from yellow to brownish. The cap typically measures between 5 to 15 cm in diameter and has a convex to flat shape as it matures. The underside of the cap features spore-bearing structures known as tubes, which are easily separable from the cap flesh. These tubes end in small pores that are initially covered by a partial veil, leaving a ring or remnants on the stipe (mushroom stem) as it disappears. The stipe itself is usually slender, measuring 4 to 10 cm in height, and may display glandular dots or streaks, especially towards the top near the cap.

The spores of Suillus glandulosipes are ellipsoid, smooth, and feature a brownish spore print. This species is distinguished from other Suillus species by its glandular-dotted stipe, the sticky cap surface, and its association with specific pine species.

Habitat and Distribution

Suillus glandulosipes is primarily found in coniferous forests, especially in symbiosis with pine trees. This mycorrhizal relationship is essential for the survival and growth of both the fungus and the host tree, as it facilitates the exchange of nutrients. The distribution of Suillus glandulosipes is closely tied to the range of its pine hosts, predominantly in North America. It is commonly found in pine plantations, mixed forests, and areas where its host trees are present.

Ecological Role

As a mycorrhizal fungus, Suillus glandulosipes plays a significant role in forest ecosystems. It helps in the nutrient cycling process, particularly in the uptake of minerals and water for the trees, while benefiting from the carbohydrates produced by the photosynthesis of its host. This mutualistic relationship enhances the growth and health of the forest, contributing to its overall biodiversity and stability.

Culinary and Medicinal Use

While many Suillus species are considered edible, the edibility of Suillus glandulosipes specifically varies. Some foragers and mushroom enthusiasts consume it, often after removing the slimy cap surface. However, as with all wild mushrooms, proper identification and knowledge of any potential toxicity are crucial before consumption. There is no significant documentation of medicinal uses of this species.

Conservation

Currently, there are no specific conservation concerns for Suillus glandulosipes, as it is not listed as endangered or threatened. However, the health of its pine forest habitats is crucial for its survival. Practices that support forest health, such as sustainable forestry and the protection of natural habitats, indirectly benefit this and other mycorrhizal fungi species.
