Suillus tomentosus
Suillus tomentosus, commonly known as the blue slide bolete or the woolly bolete, is a species of fungus belonging to the genus Suillus within the family Suillaceae. It is a mycorrhizal species, forming symbiotic relationships with the roots of pine trees, which is a characteristic trait of many members within its genus. This species is found in various parts of North America, particularly in coniferous forests where its host trees reside.
Description[edit | edit source]
Suillus tomentosus features a cap that can range from 3 to 10 cm in diameter, initially convex before flattening out with age. The cap surface is tomentose, meaning it has a soft, woolly texture, and it can vary in color from yellow-brown to olive-brown. The pores on the underside of the cap are small and round, typically yellow in color, which may bruise to a blue or blue-green when damaged. The stipe (stem) is 2 to 5 cm long and 1 to 2 cm thick, often displaying a similar coloration to the cap but may have a reddish tinge at the base. It is adorned with a woolly ring that can be quite prominent in young specimens but often disappears with age.
The spore print of Suillus tomentosus is brown, and its spores are ellipsoid and smooth. This species is considered edible, though not highly regarded due to its slimy texture and the presence of a bitter taste in some specimens.
Habitat and Distribution[edit | edit source]
Suillus tomentosus is predominantly found in North America, with a range extending from the eastern United States through to the west coast, and into Canada. It forms mycorrhizal associations with various species of pine, including ponderosa pine, lodgepole pine, and others, aiding in the nutrient uptake of these trees. The fungus prefers sandy or well-drained soils and is typically found in pine forests, often appearing after the first rains of fall.
Ecological Role[edit | edit source]
As a mycorrhizal fungus, Suillus tomentosus plays a crucial role in forest ecosystems. It helps in the nutrient cycling process, facilitating the transfer of minerals and water from the soil to the pine trees it associates with. This symbiotic relationship is beneficial for the forest as a whole, promoting healthier trees that can better resist pests and diseases.
Culinary and Medicinal Use[edit | edit source]
While Suillus tomentosus is edible, it is not among the most sought-after mushrooms due to its slimy cap and potential bitterness. If consumed, it is recommended to remove the slimy cap skin and possibly pre-boil the mushroom to reduce its bitterness. There are no well-documented medicinal uses of Suillus tomentosus.
Conservation[edit | edit source]
There are currently no major conservation concerns for Suillus tomentosus, as it is relatively widespread and common in its natural habitat. However, like many fungi, its presence is dependent on the health of its host trees and the broader ecosystem. Conservation of pine forests and maintaining natural habitats are essential for the continued survival of this species.
