Suillus placidus

Elfenbeinroehrling

Suillus placidus is a species of mushroom belonging to the genus Suillus, which is part of the family Suillaceae. This mushroom is commonly known as the placid suillus or white suillus. It is found in North America and Europe, where it forms symbiotic relationships with the roots of pine trees, a phenomenon known as mycorrhiza. This relationship is beneficial for both the tree and the mushroom, as it enhances nutrient and water absorption for the tree, while the mushroom gains carbohydrates produced by the tree through photosynthesis.

Description

Suillus placidus 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 sticky when wet, displaying a color palette that varies from creamy white to light brown. The stipe (stem) of the mushroom is slender, measuring 4 to 8 cm in height, and is typically the same color as the cap or slightly lighter. The pores on the underside of the cap are small and round, changing color from white to yellowish with age. The spore print of Suillus placidus is brown.

Habitat and Distribution

Suillus placidus is predominantly found in coniferous forests, especially those dominated by various species of pine. It is a common sight in both North America and Europe, particularly in areas where its host pine trees are abundant. The mushroom tends to grow in small groups rather than individually, often appearing in the late summer to fall.

Culinary Uses

While Suillus placidus is considered edible, it is not regarded as one of the more desirable species within the Suillus genus due to its slimy cap and mild flavor. If collected for consumption, it is recommended to remove the slimy layer from the cap to improve its texture. It can be used in a variety of dishes that call for wild mushrooms, including soups, stews, and sautés.

Conservation

As of now, Suillus placidus does not face any immediate threats that would warrant conservation concern. Its ability to form symbiotic relationships with pine trees helps ensure its proliferation as long as its host trees remain healthy and undisturbed. However, like many fungi, it could be susceptible to changes in its environment due to factors such as deforestation, pollution, and climate change.
